3
00:00:28,362 --> 00:00:31,448
NARRATOR: Our oceans are
the lifeblood of our planet.

4
00:00:37,829 --> 00:00:41,208
My grandfather, Jacques Cousteau,
inspired the world

5
00:00:41,610 --> 00:00:44,753
through his exploration,
sharing the mysteries

6
00:00:44,962 --> 00:00:47,589
of one of Earth's most important habitats.

7
00:01:07,818 --> 00:01:11,154
It was in that spirit that a team
of Disneynature filmmakers

8
00:01:11,655 --> 00:01:15,409
embarked on a quest to shed new light
on this hidden world...

9
00:01:20,664 --> 00:01:23,417
...and on one
of its most enchanting inhabitants.

10
00:01:27,379 --> 00:01:32,092
NARRATOR: For wildlife filmmakers,
the ocean presents the greatest challenge.

11
00:01:32,369 --> 00:01:34,194
It is unforgiving.

12
00:01:37,973 --> 00:01:40,684
And visits beneath the waves
are fleeting.

13
00:01:47,482 --> 00:01:51,903
Here, they will enter a realm
where they are not the masters.

14
00:01:57,284 --> 00:01:59,494
And they must be respectful of the locals.

15
00:02:00,537 --> 00:02:02,164
MAN: No, no, no, no, no!

16
00:02:05,334 --> 00:02:06,885
NARRATOR: The team's mission?

17
00:02:07,711 --> 00:02:09,504
To reveal what it's like to live...

18
00:02:09,921 --> 00:02:11,715
-...in a dolphin's world.

19
00:02:20,057 --> 00:02:24,061
In the Red Sea,
wildlife cinematographer, Roger Horrocks,

20
00:02:24,227 --> 00:02:27,230
is preparing to film
the main character of our story...

21
00:02:28,315 --> 00:02:29,650
bottlenose dolphins.

22
00:02:30,651 --> 00:02:32,819
He has filmed dolphins all over the world,

23
00:02:33,320 --> 00:02:35,822
but it's his first time in this location.

24
00:02:36,948 --> 00:02:40,827
The key to his success
lies with scientist, Angela Ziltener.

25
00:02:41,620 --> 00:02:43,997
Having studied them here
for over a decade,

26
00:02:44,247 --> 00:02:47,376
she is a virtual gatekeeper
to the Red Sea dolphins.

27
00:02:47,793 --> 00:02:50,379
Certainly, the dolphins are
probably one of the most

28
00:02:50,545 --> 00:02:52,422
charismatic animals
that you do get in the ocean.

29
00:02:52,589 --> 00:02:54,508
They're mammals,
people can relate to them.

30
00:02:54,841 --> 00:02:58,387
Um, they're very, you know,
they have a mammalian consciousness.

31
00:02:58,553 --> 00:03:01,348
So, we have a kinship with them.

32
00:03:03,809 --> 00:03:05,852
NARRATOR:
As a highly experienced free-diver,

33
00:03:06,144 --> 00:03:10,315
Roger certainly has the athleticism
to keep up with dolphins underwater.

34
00:03:11,024 --> 00:03:13,110
ROGER: Filming dolphins
is probably the most physical

35
00:03:13,276 --> 00:03:15,779
-because they are incessantly on the move.
-

36
00:03:16,697 --> 00:03:19,741
So, the biggest challenge
is really just keeping up with them

37
00:03:20,033 --> 00:03:24,246
and coming across those moments
of pure, beautiful interaction.

38
00:03:27,999 --> 00:03:29,876
It was massively helpful to have Angela,

39
00:03:30,168 --> 00:03:33,714
who has spent an incredible amount of time
in that location.

40
00:03:34,341 --> 00:03:36,842
Her knowing the dolphins
helped us tremendously.

41
00:03:38,427 --> 00:03:41,179
NARRATOR: Angela is
one of the few scientists in the world

42
00:03:41,471 --> 00:03:43,390
who studies them by scuba diving.

43
00:03:45,517 --> 00:03:49,813
It has allowed her to get to know
over 200 individual dolphins,

44
00:03:50,063 --> 00:03:52,232
-and allowed them to get to know her.
-

45
00:03:52,983 --> 00:03:57,279
ANGELA: To understand the animals,
you actually have to be one of them.

46
00:03:57,639 --> 00:04:00,449
That means not that you are
the animal itself,

47
00:04:00,809 --> 00:04:03,285
but that you are accepted in the group.

48
00:04:04,244 --> 00:04:09,291
You will actually see all the individuals
and that every dolphin is different.

49
00:04:10,292 --> 00:04:13,628
Every dolphin has their own personality,
like humans.

50
00:04:14,629 --> 00:04:16,339
-NARRATOR: The pod knows Angela,

51
00:04:17,048 --> 00:04:20,260
but will the dolphins accept
our strange new cinematographer?

52
00:04:20,844 --> 00:04:23,847
ROGER: I, kind of, knew
literally from the moment that I got in

53
00:04:24,189 --> 00:04:26,107
that this was a great opportunity.

54
00:04:26,725 --> 00:04:30,604
When those dolphins
were absolutely keen to interact,

55
00:04:30,812 --> 00:04:33,115
not only with each other,
but also with me as a cameraman...

56
00:04:33,315 --> 00:04:35,776
-...so that was just such a joy.

57
00:04:37,152 --> 00:04:40,739
Wild animals actually wanting
to be filmed. It was amazing.

58
00:04:51,833 --> 00:04:53,502
ROGER: The more we film,
the more we got a sense

59
00:04:53,668 --> 00:04:55,420
of how they operate as groups.

60
00:04:56,296 --> 00:04:59,049
You know, one thing that was very,
very marked for me

61
00:04:59,549 --> 00:05:02,761
was the degree of interaction
between the dolphins.

62
00:05:03,595 --> 00:05:06,890
It was astounding to see
how tactile they were.

63
00:05:08,850 --> 00:05:11,269
ROGER: Dolphins spent time fin rubbing,

64
00:05:11,436 --> 00:05:13,563
and touching each other,
grooming each other.

65
00:05:14,439 --> 00:05:17,108
I thought initially
it was maybe a romantic thing,

66
00:05:17,275 --> 00:05:19,528
but actually, it's a bonding thing.

67
00:05:20,237 --> 00:05:23,323
They are emotional,
highly intelligent creatures,

68
00:05:23,532 --> 00:05:25,659
-very, very similar to us.
-

69
00:05:27,494 --> 00:05:30,872
NARRATOR: And it wasn’t long
before Roger spotted another example

70
00:05:31,081 --> 00:05:32,749
of their playful intelligence.

71
00:05:36,002 --> 00:05:40,298
ROGER: A group of juveniles just came in
and they were almost showing off.

72
00:05:40,924 --> 00:05:44,761
I remember that feeling of knowing
this is a unique piece of behavior

73
00:05:44,970 --> 00:05:47,097
and probably never going to get
this chance again.

74
00:05:48,473 --> 00:05:51,101
NARRATOR:
They flick their fluke to clear the sand,

75
00:05:51,726 --> 00:05:54,104
exposing a piece of coral.

76
00:05:55,480 --> 00:05:58,859
And voilà, a toy is born.

77
00:06:09,411 --> 00:06:12,873
Few animals spend so much time playing,

78
00:06:13,606 --> 00:06:15,150
yet this perceived playfulness

79
00:06:15,333 --> 00:06:18,003
might also be one of the ways
that young dolphins

80
00:06:18,169 --> 00:06:20,255
-practice their hunting skills.
-

81
00:06:25,802 --> 00:06:27,888
ROGER: You can just, kind of,
see that intelligence

82
00:06:28,054 --> 00:06:30,140
and that mischievousness
about them,

83
00:06:30,307 --> 00:06:35,729
and again, just such an incredible insight
into how intelligent these animals are.

84
00:06:39,900 --> 00:06:42,611
I think dolphins just do it
because they absolutely love it,

85
00:06:42,777 --> 00:06:44,829
and they enjoy the skill
and the challenge.

86
00:06:49,868 --> 00:06:52,054
I think they do it
for the sheer fun of it.

87
00:07:04,674 --> 00:07:08,511
NARRATOR: Angela's research has revealed
another aspect of dolphin life

88
00:07:08,845 --> 00:07:10,555
rarely witnessed in the wild...

89
00:07:12,015 --> 00:07:13,099
sleeping.

90
00:07:16,061 --> 00:07:19,230
This group of dolphins
is so relaxed in her presence,

91
00:07:19,981 --> 00:07:21,816
they take a nap as she watches...

92
00:07:24,653 --> 00:07:25,904
and Roger films.

93
00:07:31,117 --> 00:07:34,037
Dolphins sleep
with just half the brain at a time.

94
00:07:35,622 --> 00:07:39,209
Half the brain needs to be awake
to remember to surf as to breathe

95
00:07:40,043 --> 00:07:42,629
and to keep an eye out for any danger.

96
00:07:44,631 --> 00:07:47,676
As a consequence
of having such active brains,

97
00:07:47,968 --> 00:07:52,347
wild dolphins, just like us,
need lots of sleep.

98
00:07:54,641 --> 00:07:57,268
ROGER: They do these beautiful movements,
synchronized movements where they

99
00:07:57,485 --> 00:07:59,237
come up and they go back down again.

100
00:08:00,563 --> 00:08:04,109
It's very, you know, very soporific,
very slow.

101
00:08:05,151 --> 00:08:07,278
Really, really beautiful to watch.

102
00:08:09,698 --> 00:08:11,241
It just felt very poetic.

103
00:08:20,625 --> 00:08:23,211
NARRATOR: Thanks to Angela,
Roger and the team

104
00:08:23,530 --> 00:08:27,924
are starting to get a taste
of what it's like to be a wild dolphin.

105
00:08:29,092 --> 00:08:33,430
Knowledge they will need to build on,
in the next leg of their adventure.

106
00:08:35,890 --> 00:08:40,437
It was just an absolute privilege
to be... to have that kind of access

107
00:08:40,603 --> 00:08:45,316
to, you know, these animals on their terms
because they choose to be with you.

108
00:08:45,483 --> 00:08:47,694
You know, you can't force them
to be with you, and I think,

109
00:08:48,153 --> 00:08:50,280
you know, of all the locations I've dived,

110
00:08:50,822 --> 00:08:52,407
they were the most welcoming,

111
00:08:52,615 --> 00:08:56,369
um, and that was, you know,
something that I'll never forget.

112
00:08:58,705 --> 00:09:01,124
NARRATOR:
Roger has made filming dolphins look easy,

113
00:09:01,958 --> 00:09:06,129
but will cinematographer, Didier Noirot,
have the same luck in Hawaii

114
00:09:06,504 --> 00:09:09,257
filming the next main characters
of our story?

115
00:09:12,677 --> 00:09:13,970
Humpback whales.

116
00:09:18,349 --> 00:09:22,020
Hawaii is a very good location to film
humpback whales...

117
00:09:23,063 --> 00:09:25,398
because of the whale population.

118
00:09:25,857 --> 00:09:28,318
-DIDIER: You're sure to see whales there.
-

119
00:09:28,568 --> 00:09:32,739
DIDIER: Crystal clear water,
so, that's perfect place to film whales.

120
00:09:33,948 --> 00:09:38,661
NARRATOR: It is also here that every year,
the females give birth to their calves.

121
00:09:41,122 --> 00:09:44,292
And filming a mother and calf
is the team's first task.

122
00:09:46,753 --> 00:09:48,797
They set out aboard the Luckey Strike

123
00:09:49,756 --> 00:09:51,216
where skipper Tad Luckey

124
00:09:51,716 --> 00:09:55,011
and a group of scientists
led by Professor Joe Mobley

125
00:09:55,386 --> 00:09:58,515
are their best chance
for locating these family pairs.

126
00:09:59,599 --> 00:10:01,226
This is always a big challenge.

127
00:10:01,559 --> 00:10:04,354
You don't know what you get,
never in advance.

128
00:10:04,562 --> 00:10:06,147
These whales are so difficult.

129
00:10:06,898 --> 00:10:10,652
It's very tricky for the producer, I mean.

130
00:10:11,945 --> 00:10:14,572
NARRATOR: Finding a whale in Hawaii
is not that hard,

131
00:10:15,115 --> 00:10:17,826
but skipper Tad
has to find the right whale,

132
00:10:18,451 --> 00:10:19,911
and that's the challenge.

133
00:10:20,662 --> 00:10:23,790
DIDIER: To find the right whale to film,

134
00:10:24,374 --> 00:10:27,877
especially mom and calf,
I have no expectation.

135
00:10:28,336 --> 00:10:32,507
That means I never know
what I'm going to get on camera.

136
00:10:34,717 --> 00:10:38,221
NARRATOR: As part of Jacques Cousteau's
original expedition team,

137
00:10:38,888 --> 00:10:42,809
Didier has over 30 years' experience
filming whales.

138
00:10:43,768 --> 00:10:44,894
I have 200.

139
00:10:45,687 --> 00:10:48,606
NARRATOR: But each opportunity
is always unpredictable.

140
00:10:51,484 --> 00:10:53,486
Come on. Come on.

141
00:10:55,479 --> 00:10:57,406
NARRATOR: It is a mother and calf

142
00:10:58,324 --> 00:11:02,662
but will Mom accept Didier
as easily as the dolphins warmed to Roger?

143
00:11:03,663 --> 00:11:04,706
You can try.

144
00:11:05,665 --> 00:11:07,170
Go ahead.

145
00:11:08,001 --> 00:11:10,670
DIDIER: The difficult thing to film
when you film mother and calf

146
00:11:10,837 --> 00:11:14,716
is to get close, silently,
as close as you get.

147
00:11:15,633 --> 00:11:19,053
NARRATOR:
He uses a bubble-free rebreather apparatus

148
00:11:19,429 --> 00:11:21,097
to silently approach.

149
00:11:25,643 --> 00:11:29,480
And any whale that doesn't accept
Didier's presence is left alone.

150
00:11:33,886 --> 00:11:36,196
The team needs to find a friendly whale

151
00:11:36,779 --> 00:11:38,489
that is comfortable around a diver.

152
00:11:44,078 --> 00:11:45,205
Well, they just left.

153
00:11:45,914 --> 00:11:48,875
We were ready to go, but now they are far.

154
00:11:50,627 --> 00:11:53,129
NARRATOR: But attempts to film
another mom and calf...

155
00:11:54,005 --> 00:11:55,340
produced the same result.

156
00:11:55,882 --> 00:11:59,594
DIDIER: When you see mother and calf,
the mother is always very aware.

157
00:11:59,928 --> 00:12:03,473
She's protecting the calf,
so any unknown thing

158
00:12:03,640 --> 00:12:06,351
like me would make her alert.

159
00:12:07,310 --> 00:12:08,728
Take two for nothing.

160
00:12:12,649 --> 00:12:14,234
NARRATOR: Another one gets away.

161
00:12:15,777 --> 00:12:19,113
-The mom and calf left.
-WOMAN: You have nothing, huh?

162
00:12:23,618 --> 00:12:24,619
Go.

163
00:12:30,550 --> 00:12:33,302
NARRATOR:
Didier is becoming all too familiar

164
00:12:33,503 --> 00:12:35,755
with the backsides of mother whales.

165
00:12:41,678 --> 00:12:43,805
DIDIER: So, you have to keep trying,

166
00:12:44,264 --> 00:12:49,185
finding a whale, new whale,
and one that lets you come close.

167
00:12:56,609 --> 00:12:59,529
NARRATOR:
After a long, unsuccessful day,

168
00:12:59,946 --> 00:13:02,240
he makes one last attempt.

169
00:13:02,600 --> 00:13:04,784
DIDIER:
By the way, this is the ninth time.

170
00:13:07,912 --> 00:13:09,998
NARRATOR: Then, a stroke of luck.

171
00:13:10,373 --> 00:13:14,210
Didier has found a playful,
approachable calf.

172
00:13:14,544 --> 00:13:18,506
DIDIER: You don't dive and go straight
for the mom with the calf underneath.

173
00:13:18,715 --> 00:13:21,384
You first have to make friends
with the calf.

174
00:13:22,010 --> 00:13:25,555
If the calf stays around you,
that he is not scared, then turns around,

175
00:13:25,972 --> 00:13:28,891
the whale will know down there,
even if she sleeps,

176
00:13:29,267 --> 00:13:31,227
you know, she knows that there is someone,

177
00:13:31,686 --> 00:13:34,564
but she knows the calf is happy
with this someone,

178
00:13:35,106 --> 00:13:37,025
so she may tolerate that.

179
00:13:41,529 --> 00:13:44,615
NARRATOR: And as it dives back
under its mother to rest,

180
00:13:45,033 --> 00:13:48,411
-Didier follows quietly.
-

181
00:13:48,661 --> 00:13:51,956
DIDIER: Now is the time,
because maybe after the whale will leave,

182
00:13:52,290 --> 00:13:55,001
and I will lose her for good.

183
00:13:55,293 --> 00:13:58,629
So, I decided to swim very, very slowly,

184
00:13:59,088 --> 00:14:02,091
and without making any noise at all.

185
00:14:07,263 --> 00:14:09,015
NARRATOR: Mom watches him carefully,

186
00:14:09,682 --> 00:14:12,185
but she seems content
with him alongside her.

187
00:14:15,063 --> 00:14:17,148
Finally, success.

188
00:14:19,233 --> 00:14:20,526
Divers like Didier...

189
00:14:20,943 --> 00:14:24,947
are just humble visitors
in this vast undersea world...

190
00:14:26,616 --> 00:14:28,910
but even the most powerful of creatures

191
00:14:29,118 --> 00:14:31,537
will sometimes allow you
to get close to them.

192
00:14:35,124 --> 00:14:36,959
After weeks of persistence,

193
00:14:37,251 --> 00:14:41,047
the team finally succeeded in filming
a mother and calf.

194
00:14:42,590 --> 00:14:46,928
This mother's duty is to protect her calf
while it grows quickly,

195
00:14:47,261 --> 00:14:51,101
before the long migration
back to Arctic waters.

196
00:14:51,349 --> 00:14:53,643
As they travel between resting spots,

197
00:14:53,976 --> 00:14:57,772
the mother encourages her calf
to breach repeatedly.

198
00:15:05,113 --> 00:15:07,907
It may look like just some fun
splashing about,

199
00:15:08,314 --> 00:15:12,620
but it's key to helping the young calf
build strength and muscles,

200
00:15:13,214 --> 00:15:15,540
that also develops
their breath-holding abilities.

201
00:15:31,264 --> 00:15:34,308
The close bond
between a mother whale and her calf

202
00:15:34,559 --> 00:15:37,478
provide our filmmakers
with their first inroad

203
00:15:37,687 --> 00:15:39,647
into humpback whale society.

204
00:15:41,983 --> 00:15:44,861
Shallow coastal waters
are the perfect sanctuary

205
00:15:45,403 --> 00:15:48,239
for a young calf
to grow healthy and strong.

206
00:15:49,157 --> 00:15:52,452
Away from the dangers
found in deeper, open waters.

207
00:15:56,539 --> 00:15:59,292
But it is also where it will soon
be introduced

208
00:15:59,584 --> 00:16:01,461
to a greater whale community,

209
00:16:02,170 --> 00:16:03,713
a complex society...

210
00:16:04,797 --> 00:16:08,426
one our team
is just beginning to understand.

211
00:16:13,681 --> 00:16:16,100
To truly understand a dolphin's world...

212
00:16:17,059 --> 00:16:21,063
the filmmakers need to journey
to the very heart of their ocean home.

213
00:16:23,232 --> 00:16:25,526
To the foundations of the whole story.

214
00:16:26,694 --> 00:16:29,030
A delicately balanced ecosystem...

215
00:16:29,780 --> 00:16:33,618
that is sanctuary to millions
of incredible supporting characters.

216
00:16:35,703 --> 00:16:37,163
A coral reef.

217
00:16:38,915 --> 00:16:41,792
Capturing the intricacies
of this underwater world

218
00:16:42,335 --> 00:16:45,254
requires a great deal
of technical camera skill

219
00:16:45,630 --> 00:16:48,966
and an exceptional eye
for precision and detail.

220
00:16:51,177 --> 00:16:55,181
Cinematographer, Doug Anderson,
is the perfect choice for such a job.

221
00:16:56,807 --> 00:16:59,352
DOUG: We wanted to make that experience
of viewing the reef

222
00:16:59,519 --> 00:17:00,937
as immersive as possible.

223
00:17:01,103 --> 00:17:02,522
So, we tried different techniques...

224
00:17:02,813 --> 00:17:05,191
...as many things
as we could think of

225
00:17:05,358 --> 00:17:08,486
to try and get
more engaging photography.

226
00:17:10,905 --> 00:17:12,448
Uh, we used this underwater scooter,

227
00:17:12,615 --> 00:17:15,493
which is like a torpedo
with a propeller on it,

228
00:17:15,868 --> 00:17:19,664
to get that feeling of the dolphin
like gliding over the reef.

229
00:17:26,337 --> 00:17:29,131
We used a jib, which is like a camera
on the end of an arm,

230
00:17:29,298 --> 00:17:31,717
which allowed us to make
for very stable tracking moves

231
00:17:31,884 --> 00:17:34,220
over the coral reef,
and really try and bring

232
00:17:34,387 --> 00:17:38,808
the character of the individual species
that we wanted to include

233
00:17:39,175 --> 00:17:40,176
to the screen.

234
00:17:47,984 --> 00:17:50,898
Of all the underwater habitats
on the planet,

235
00:17:51,153 --> 00:17:54,198
it's coral reefs
that are the most overtly diverse.

236
00:17:55,491 --> 00:18:00,871
Just amazed by the color, and the life,
and beauty in front of me.

237
00:18:02,121 --> 00:18:04,333
Absolutely breathtaking when you're there.

238
00:18:07,128 --> 00:18:09,505
Intense experiences of life.

239
00:18:18,848 --> 00:18:21,225
I like to think of a coral reef
a bit like a city.

240
00:18:22,751 --> 00:18:24,826
The buildings are the corals.

241
00:18:27,398 --> 00:18:32,403
Those buildings provide homes
and habitat for countless animals.

242
00:18:34,639 --> 00:18:37,617
Every animal that lives there
is as important to each other

243
00:18:37,783 --> 00:18:39,035
as the next one.

244
00:18:40,494 --> 00:18:42,814
But there are very obvious animals
in the coral reef

245
00:18:43,247 --> 00:18:44,957
that do very important jobs.

246
00:18:48,878 --> 00:18:51,464
NARRATOR: Doug wants to find
key characters like these...

247
00:18:52,256 --> 00:18:54,675
to highlight critical links
in the community.

248
00:18:56,132 --> 00:18:59,180
These handsome devils
are the perfect example.

249
00:19:00,556 --> 00:19:01,974
Bumphead parrotfish.

250
00:19:04,610 --> 00:19:06,571
They are the local groundskeepers,

251
00:19:06,896 --> 00:19:10,207
clearing the reef
of dead algae-covered coral.

252
00:19:15,404 --> 00:19:21,077
Recently, as our oceans have warmed,
coral reefs have bleached and died.

253
00:19:22,078 --> 00:19:24,538
Reefs with parrotfish are quickly cleaned,

254
00:19:24,872 --> 00:19:28,501
and new coral can recolonize
so the reef lives on.

255
00:19:30,044 --> 00:19:33,756
Reefs that have lost
to their parrotfish rarely recover.

256
00:19:38,469 --> 00:19:41,430
Parrotfish are important
to maintain the health of the reef...

257
00:19:42,598 --> 00:19:45,309
but Doug also discovers
another important fish.

258
00:19:46,185 --> 00:19:49,522
The incredible, workaholic cleaner wrasse.

259
00:19:52,358 --> 00:19:55,361
DOUG: There are moments in the reef
where it becomes very obvious

260
00:19:55,528 --> 00:19:57,738
how controlled and complex

261
00:19:57,947 --> 00:20:00,574
the relationships
between the individual animals are.

262
00:20:01,027 --> 00:20:04,328
And one of them, for sure,
is watching cleaner wrasse do their work.

263
00:20:06,330 --> 00:20:08,457
They do an enormously important job,

264
00:20:08,624 --> 00:20:11,043
and that's pick the parasites
and dead skin

265
00:20:11,335 --> 00:20:12,628
and scales and everything else off.

266
00:20:13,003 --> 00:20:14,755
You know, they're getting
right inside their mouths

267
00:20:14,922 --> 00:20:18,467
and inside their gills.
They're constantly busy.

268
00:20:19,009 --> 00:20:21,804
They are just so fun to watch.

269
00:20:23,222 --> 00:20:24,849
And they, kind of,
do this funny little dance

270
00:20:25,015 --> 00:20:26,434
to try and bring in business.

271
00:20:29,270 --> 00:20:31,397
Everyone comes to their cleaning stations.

272
00:20:32,264 --> 00:20:33,724
Cute little reef fish.

273
00:20:34,859 --> 00:20:36,736
And then you've got big predators.

274
00:20:37,903 --> 00:20:39,613
I tell you, it really takes
your breath away

275
00:20:39,947 --> 00:20:41,031
when you watch a cleaner wrasse

276
00:20:41,240 --> 00:20:43,409
going into the mouth
of a two-feet predator.

277
00:20:44,410 --> 00:20:46,120
There's just this convention
on the reef,

278
00:20:46,203 --> 00:20:50,708
they do not touch the cleaner wrasse.
It's one of those really lovely examples

279
00:20:50,958 --> 00:20:54,712
of how intricate
the relationships on a reef are.

280
00:20:58,841 --> 00:21:01,719
NARRATOR: While Doug continues
to explore the interconnections

281
00:21:01,886 --> 00:21:03,637
between the fish and the reef...

282
00:21:05,097 --> 00:21:08,267
back in the Red Sea,
Roger is about to find out

283
00:21:08,684 --> 00:21:11,312
that dolphins have similar dependencies.

284
00:21:13,981 --> 00:21:16,817
Angela has discovered
an incredible connection

285
00:21:17,109 --> 00:21:19,320
that dolphins have with the coral here.

286
00:21:19,663 --> 00:21:22,907
ROGER: I was really excited
about this one particular unique behavior

287
00:21:23,449 --> 00:21:24,617
that Angela had told me about,

288
00:21:24,859 --> 00:21:27,736
which I was really determined
to capture on film.

289
00:21:35,628 --> 00:21:38,547
NARRATOR: Angela has brought Roger
to a very special location

290
00:21:38,756 --> 00:21:40,883
that the dolphins
like to visit every day...

291
00:21:43,010 --> 00:21:45,429
and from which they reap great benefits.

292
00:21:46,388 --> 00:21:49,186
ROGER: The key focus for me
was that feeling, as a cameraman,

293
00:21:49,336 --> 00:21:53,395
knowing this is a unique piece of behavior
and is that wonderful pressure...

294
00:21:53,562 --> 00:21:55,356
-...to get it into the film.

295
00:22:02,029 --> 00:22:04,865
NARRATOR: Angela's hard-earned
acceptance by the dolphins

296
00:22:05,241 --> 00:22:09,703
is what allowed her to follow them
and make this incredible discovery.

297
00:22:11,497 --> 00:22:13,415
ANGELA:
There is one certain kind of coral.

298
00:22:13,666 --> 00:22:15,417
It's called the gorgonian coral.

299
00:22:16,126 --> 00:22:22,466
And they really like to rub each body part
in this coral because it's quite soft.

300
00:22:29,682 --> 00:22:31,559
This rubbing behavior seems to be

301
00:22:31,767 --> 00:22:35,104
such an important aspect
in their daily life.

302
00:22:40,442 --> 00:22:43,445
ROGER: So, it's so wonderful
to see them, kind of, lining up.

303
00:22:44,488 --> 00:22:46,991
And they're very gentle.
They don't like fight to get through.

304
00:22:47,157 --> 00:22:50,578
And they're very courteous and allow
the one to go after the other.

305
00:22:51,537 --> 00:22:53,622
And then they circle back
and go through again.

306
00:23:00,713 --> 00:23:03,257
So, it's a wonderful
social ritual as well.

307
00:23:07,720 --> 00:23:10,014
ANGELA: What we also know
about different corals,

308
00:23:10,180 --> 00:23:12,266
they have antibacterial substances.

309
00:23:13,851 --> 00:23:17,646
So, it could also be
that the dolphins actually use also

310
00:23:17,813 --> 00:23:23,903
these corals for medicine, for example,
for even prevention for skin diseases.

311
00:23:26,322 --> 00:23:28,032
It's difficult to really prove it

312
00:23:28,282 --> 00:23:31,619
because it can be also
a very nice feeling,

313
00:23:32,411 --> 00:23:37,666
but we have to find out if it's a really
awareness of self-medication.

314
00:23:39,001 --> 00:23:41,337
NARRATOR:
Angela's groundbreaking observations

315
00:23:41,712 --> 00:23:43,464
have broaden our understanding,

316
00:23:43,881 --> 00:23:47,843
and also pose important new questions
about dolphin behavior.

317
00:23:49,762 --> 00:23:52,723
ROGER: The hypothesis
that Angela's exploring,

318
00:23:53,182 --> 00:23:55,351
and you know,
if this can be proven to be true,

319
00:23:55,726 --> 00:23:58,520
it just highlights the amazing
interdependence

320
00:23:58,687 --> 00:24:01,023
between these mammals
and the coral reefs.

321
00:24:02,566 --> 00:24:06,487
Not only do they come here
to rest and to play and to feel safe,

322
00:24:07,404 --> 00:24:10,366
but they're also actually coming
to heal themselves.

323
00:24:13,827 --> 00:24:17,206
NARRATOR: Angela hopes to reveal
more about these dolphins' lives

324
00:24:17,790 --> 00:24:20,501
so that we can protect them
and their reef home

325
00:24:20,751 --> 00:24:22,294
long into the future.

326
00:24:25,881 --> 00:24:30,344
But a coral reef doesn't always provide
a healthy sanctuary to its residents,

327
00:24:31,011 --> 00:24:33,180
as Doug is about to find out.

328
00:24:34,431 --> 00:24:38,102
DOUG: Obviously we have this vibrancy,
this color, this beauty.

329
00:24:38,268 --> 00:24:40,229
It's that, you know,
the light side of the reef,

330
00:24:40,496 --> 00:24:43,749
but the reef has its back alleys, too.

331
00:24:45,150 --> 00:24:46,694
It's got its dark places.

332
00:24:47,444 --> 00:24:48,862
Places where...

333
00:24:49,029 --> 00:24:54,493
you know, visually, things aren't just
all joy and beauty and vibrancy,

334
00:24:54,827 --> 00:24:57,955
but feel a little bit more
on the sinister side.

335
00:25:00,332 --> 00:25:04,461
NARRATOR: They are the places
that most divers dare not venture.

336
00:25:06,797 --> 00:25:08,549
Doug and his team are in Malaysia,

337
00:25:09,341 --> 00:25:10,676
on their way to Sipadan,

338
00:25:11,051 --> 00:25:15,097
an oceanic island
with a unique and hidden secret

339
00:25:15,514 --> 00:25:18,600
that reveals the dangers
some of our characters face

340
00:25:18,892 --> 00:25:20,561
right in their backyard.

341
00:25:21,478 --> 00:25:24,481
Sipadan is an extraordinary,
little island.

342
00:25:25,274 --> 00:25:28,986
It's a rock in the middle
of hundreds of meters of water.

343
00:25:29,653 --> 00:25:31,447
And it's a marine reserve,

344
00:25:31,613 --> 00:25:35,451
and there is just
an absolute heap of turtles here.

345
00:25:39,955 --> 00:25:42,541
NARRATOR: This reef would seem
like the perfect sanctuary.

346
00:25:44,293 --> 00:25:48,255
But beneath its tranquil shell
hides potential catastrophe

347
00:25:48,589 --> 00:25:50,257
for any wayward turtle.

348
00:25:52,468 --> 00:25:55,888
Inside the reef structure,
there's a catacomb.

349
00:25:56,263 --> 00:25:58,265
And that's what they are here to film.

350
00:25:59,043 --> 00:26:02,102
DOUG: I had heard of Turtle Cave
20 years previously,

351
00:26:02,478 --> 00:26:04,188
and how tricky it was to get in.

352
00:26:06,815 --> 00:26:09,443
...a small operation.
Just even getting the kit in there,

353
00:26:09,610 --> 00:26:12,529
before we even start thinking
of lighting it or doing the photography.

354
00:26:13,906 --> 00:26:15,574
We've got a jib,
which is like a big boom

355
00:26:15,741 --> 00:26:18,077
with a camera on one end
and weights on the other.

356
00:26:19,661 --> 00:26:21,330
We've got communications underwater,

357
00:26:21,622 --> 00:26:23,499
which mean that we can
talk to each other.

358
00:26:25,375 --> 00:26:26,960
We do have comms with the boat,

359
00:26:27,252 --> 00:26:30,172
um, but we lose that as soon
as we're through the cave entrance.

360
00:26:30,631 --> 00:26:32,633
Topside, topside, this is divers.

361
00:26:32,841 --> 00:26:34,760
We are just about to enter the cave.

362
00:26:34,968 --> 00:26:36,095
See you on the other side.

363
00:26:36,512 --> 00:26:38,597
HELEN: They could be down there
for a good three hours.

364
00:26:39,848 --> 00:26:41,183
If anything does go wrong,

365
00:26:41,391 --> 00:26:44,019
there's really nothing
that we can do from up here.

366
00:26:44,394 --> 00:26:46,105
All we can really do is wait.

367
00:26:47,848 --> 00:26:50,892
So, fingers crossed,
it all goes according to plan.

368
00:26:51,401 --> 00:26:52,986
Oh, divers

369
00:26:54,196 --> 00:26:57,032
Divers, divers, are you okay?

370
00:26:58,909 --> 00:27:00,619
We're at the cave

371
00:27:01,354 --> 00:27:04,679
Such a spooky place

372
00:27:04,957 --> 00:27:06,750
Very eerie

373
00:27:07,334 --> 00:27:08,961
Oh, divers...

374
00:27:10,921 --> 00:27:13,757
DOUG: We realize that this is going to be
a really tough place for us to work.

375
00:27:14,133 --> 00:27:15,425
We have to lay lines

376
00:27:15,717 --> 00:27:18,262
so that we could feel our way
in and out of the cave.

377
00:27:19,263 --> 00:27:21,807
There's no light in there.
It's a small passage.

378
00:27:22,099 --> 00:27:24,017
We only illuminate it with a flashlight.

379
00:27:25,511 --> 00:27:28,722
Okay now, so, you're getting glimpses
of just how remote

380
00:27:29,164 --> 00:27:31,166
and how difficult to get into,
and therefore,

381
00:27:31,433 --> 00:27:33,348
difficult to get out of this space was.

382
00:27:35,445 --> 00:27:37,781
I never felt completely at ease.

383
00:27:46,123 --> 00:27:48,709
DOUG: Usually, you know,
when you're diving open ocean,

384
00:27:49,001 --> 00:27:52,087
you get a problem, you run out of gas,
you got an equipment problem,

385
00:27:52,462 --> 00:27:55,340
you just go up. And in a cave,
you can't do that.

386
00:27:55,507 --> 00:27:58,844
You know, there's only out.

387
00:28:01,305 --> 00:28:03,765
And then, obviously, the other big thing
is it's dark in there, you know,

388
00:28:03,891 --> 00:28:06,643
from an equipment point of view,
so we're going to have to light it.

389
00:28:07,144 --> 00:28:10,689
Most of the thought went into how
we were going to logistically do it

390
00:28:10,856 --> 00:28:13,650
rather than the actual visuals
of what it was going to look like.

391
00:28:13,984 --> 00:28:17,154
Then it really wasn't until I turned
the lights on in the cave

392
00:28:17,321 --> 00:28:19,364
that I really got a sense
of what sort of place it was.

393
00:28:20,949 --> 00:28:23,243
What I saw was a tomb.

394
00:28:24,036 --> 00:28:25,954
And on the ledges of these caverns

395
00:28:26,371 --> 00:28:28,957
lay the almost perfect skeletons
of green turtles

396
00:28:29,249 --> 00:28:31,251
that had, over the years, died there.

397
00:28:40,469 --> 00:28:42,804
This turtle behind you

398
00:28:44,681 --> 00:28:47,976
Wondering what you are doing

399
00:28:48,810 --> 00:28:50,562
Filming in the cave

400
00:28:51,772 --> 00:28:54,233
He wants to come with you

401
00:28:54,983 --> 00:28:58,195
With you, come with you...

402
00:28:58,654 --> 00:29:01,615
NARRATOR: Doug must move
very slowly and carefully.

403
00:29:02,366 --> 00:29:05,077
The cave floor is covered
in fine sediment.

404
00:29:09,748 --> 00:29:12,334
Some believe this to be
the powdered remains

405
00:29:12,834 --> 00:29:18,423
of thousands of turtle skeletons
that have crumbled over countless ages.

406
00:29:18,966 --> 00:29:22,386
And one false move
could cloud the entire cave,

407
00:29:22,636 --> 00:29:25,973
making it difficult for the crew
to find their way out.

408
00:29:31,979 --> 00:29:34,314
After hours of meticulous setup,

409
00:29:35,274 --> 00:29:38,193
Doug starts to reveal
the cave's haunting secrets

410
00:29:38,443 --> 00:29:42,990
from the perspective of a turtle
who has tragically lost its way.

411
00:29:50,789 --> 00:29:52,541
DOUG: It felt like being in a church.

412
00:29:53,583 --> 00:29:55,419
I felt enormous respect for the place.

413
00:29:56,295 --> 00:29:58,880
There was a sense of peace and reverence.

414
00:30:00,215 --> 00:30:03,802
An eerie connection to something.

415
00:30:05,470 --> 00:30:06,680
We all felt it.

416
00:30:07,806 --> 00:30:10,809
A coral reef, in many ways,
is a giver of life...

417
00:30:11,893 --> 00:30:13,186
but it also takes.

418
00:30:15,814 --> 00:30:19,192
NARRATOR: Hours later,
they make their way back to the surface

419
00:30:19,693 --> 00:30:23,030
-and to the safety of the boat.
-

420
00:30:25,824 --> 00:30:27,826
For you...

421
00:30:40,147 --> 00:30:43,108
That was so much more special
than I thought it would be.

422
00:30:43,467 --> 00:30:47,054
It was really quite touching
to see all these turtle skeletons

423
00:30:47,262 --> 00:30:49,514
in the bottom of the cave,
and then, you know,

424
00:30:49,681 --> 00:30:52,768
just imagining the turtles
when they got lost in there

425
00:30:52,851 --> 00:30:55,062
and how scared and afraid
they must've been.

426
00:30:59,232 --> 00:31:02,027
NARRATOR: To convey the broader story
of this undersea world,

427
00:31:02,402 --> 00:31:05,489
the filmmakers wanted to balance
these harsh realities

428
00:31:06,198 --> 00:31:08,533
with scenes of beauty and enchantment.

429
00:31:09,618 --> 00:31:10,911
And back in Hawaii,

430
00:31:11,328 --> 00:31:14,915
Didier has found
the greatest enchantment of all.

431
00:31:17,167 --> 00:31:19,544
A singing male humpback whale

432
00:31:20,170 --> 00:31:24,174
with hundreds of others
from miles around joining the chorus.

433
00:31:27,886 --> 00:31:30,931
NARRATOR: Just 50 years ago,
these waters were quiet.

434
00:31:33,225 --> 00:31:37,104
Scientist, Joe Mobley, has been monitoring
their population recovery.

435
00:31:39,523 --> 00:31:42,776
JOE: Humpback whales in North Pacific
were hunted to near extinction

436
00:31:42,968 --> 00:31:45,220
until they were protected in 1966.

437
00:31:45,695 --> 00:31:47,739
At that time, there were probably
under a thousand whales

438
00:31:47,948 --> 00:31:48,949
that came to Hawaii.

439
00:31:49,574 --> 00:31:51,576
But now, 50 years later,

440
00:31:51,993 --> 00:31:56,123
there are maybe as many as 10,000 animals
that visit the Hawaiian Islands.

441
00:31:57,749 --> 00:32:01,294
So, this day on the Luckey Strike,
we were looking for a singer.

442
00:32:01,810 --> 00:32:04,423
To show that the whales
communicate together,

443
00:32:04,589 --> 00:32:06,174
it's part of a community.

444
00:32:06,425 --> 00:32:10,720
NARRATOR: But nothing prepared Didier
for what he was about to encounter.

445
00:32:10,846 --> 00:32:12,514
...hundred feet down
and we can see the back fins.

446
00:32:12,764 --> 00:32:14,599
There are a lot of mackerel showing here,
which is...

447
00:32:15,100 --> 00:32:17,811
That's a whale right here,
this red mark right here.

448
00:32:18,562 --> 00:32:21,022
-It's down a hundred feet.
-He's right there.

449
00:32:21,231 --> 00:32:24,067
-He was singing away...
-DIDIER: I heard it, too.

450
00:32:24,234 --> 00:32:25,652
Well, the girls said they could hear him

451
00:32:25,777 --> 00:32:27,863
-clear as could be on the bow.
-DIDIER: Yeah.

452
00:32:29,781 --> 00:32:33,118
DIDIER: Being on the boat,
we can hear the male singing so strong

453
00:32:33,285 --> 00:32:35,162
when you are right above the singer.

454
00:32:37,581 --> 00:32:39,416
-We can still hear him.
-DIDIER: Yeah, yeah, yeah.

455
00:32:39,708 --> 00:32:40,876
So, we're very close.

456
00:32:42,377 --> 00:32:44,921
DIDIER:
So, gently, we went down into the water.

457
00:32:54,806 --> 00:32:58,268
DIDIER:
Today I looked down, then two whales came,

458
00:32:58,602 --> 00:33:02,314
and they start to move
and to stop in front of me.

459
00:33:02,898 --> 00:33:04,232
Right in front of me.

460
00:33:16,161 --> 00:33:20,332
NARRATOR: Then, an unimaginable event
began to unfold

461
00:33:20,540 --> 00:33:21,917
before Didier's eyes.

462
00:33:26,922 --> 00:33:31,635
DIDIER: Then, a third whale came,
and they start to dance together.

463
00:34:20,392 --> 00:34:27,357
It's really a gift from nature
to be first row in the theater.

464
00:34:33,613 --> 00:34:35,198
Diving with those giants,

465
00:34:35,865 --> 00:34:38,994
you finally realize how small you are.

466
00:34:51,172 --> 00:34:54,797
That was one of the best moments
of my life.

467
00:34:55,051 --> 00:34:56,761
That was just magnificent.

468
00:35:08,441 --> 00:35:10,191
You can't forget any of those moments

469
00:35:10,400 --> 00:35:13,987
when you are alone, very small
next to those giants, you know.

470
00:35:14,195 --> 00:35:16,740
So, it is really something like it is...

471
00:35:17,073 --> 00:35:19,284
I will keep in my memory forever.

472
00:35:21,202 --> 00:35:25,040
NARRATOR: What Didier has managed
to capture is just a tiny glimpse

473
00:35:25,457 --> 00:35:28,627
into the humpback's complex,
social behavior.

474
00:35:29,878 --> 00:35:32,797
But we are yet to understand
the true meaning

475
00:35:32,964 --> 00:35:35,216
of this magnificent whale ballet.

476
00:35:40,597 --> 00:35:45,018
Dolphins take their social activities
to a whole new level.

477
00:35:47,187 --> 00:35:50,982
And the team wanted to show
exactly how they get their thrills.

478
00:35:52,317 --> 00:35:53,985
ROGER:
They're a symbol of freedom, you know.

479
00:35:54,194 --> 00:35:56,446
They roam the oceans.
They're not constrained.

480
00:35:56,704 --> 00:36:02,243
And you really see that perhaps,
most beautifully expressed when they surf.

481
00:36:04,079 --> 00:36:06,247
NARRATOR:
Surfing dolphins are a regular sight

482
00:36:06,456 --> 00:36:09,751
on the Wild Coast of South Africa,
where Roger grew up.

483
00:36:11,211 --> 00:36:16,091
Now, he's returning to his roots
with a team of big wave specialists

484
00:36:16,591 --> 00:36:19,552
to try and film
this amazing dolphin behavior.

485
00:36:22,430 --> 00:36:25,684
ROGER: The reason we chose the Wild Coast
is that we know it's got dolphins.

486
00:36:25,892 --> 00:36:28,353
We know that in the winter,
when the winter swells come through,

487
00:36:28,520 --> 00:36:29,979
it's got these incredible swells.

488
00:36:31,481 --> 00:36:34,192
NARRATOR: And Roger's goal
is to film them by getting

489
00:36:34,526 --> 00:36:36,945
right inside the surf zone.

490
00:36:39,114 --> 00:36:41,324
Fellow cinematographer, Jamie McPherson,

491
00:36:41,574 --> 00:36:45,995
has attached a gyro-stabilized camera
on the back of a high-speed boat,

492
00:36:46,430 --> 00:36:51,251
while skipper, Carl, negotiates the boat
behind the breaking waves.

493
00:36:53,002 --> 00:36:55,797
Pro surf veteran, Paris,
will use a jet ski

494
00:36:55,964 --> 00:36:59,134
to place Roger
right in front of the break.

495
00:37:01,010 --> 00:37:02,220
The stage is set,

496
00:37:02,804 --> 00:37:05,473
and the dolphins have turned up
as if on cue,

497
00:37:05,849 --> 00:37:08,101
traveling up the coastline
in large groups.

498
00:37:09,644 --> 00:37:12,981
But the crew have just met
their first hurdle.

499
00:37:13,565 --> 00:37:19,529
Ironically, the infamous Wild Coast
has turned completely calm.

500
00:37:21,573 --> 00:37:25,034
We've passed literally, I would say,
two to three hundred dolphins,

501
00:37:25,301 --> 00:37:28,304
maybe, you know, in about
six or seven different pods.

502
00:37:28,538 --> 00:37:32,584
So, the dolphins are here,
but absolutely no swell.

503
00:37:33,042 --> 00:37:35,253
It's good that we got dolphins,
we just need a decent wave.

504
00:37:35,470 --> 00:37:37,430
At the moment we got no decent wave, so...

505
00:37:38,631 --> 00:37:41,176
Hopefully in the next two days,
we're supposed to get some better swells.

506
00:37:41,342 --> 00:37:44,679
So, it's just a case of waiting
and hoping that the swell picks up

507
00:37:44,846 --> 00:37:48,057
and that dolphins actually fancy
having a surf.

508
00:37:52,687 --> 00:37:56,733
But what we did get
was this incredibly clean patch of water,

509
00:37:56,941 --> 00:37:59,277
which in the Transkei
is very, very unusual.

510
00:38:00,195 --> 00:38:01,529
So, we took this opportunity

511
00:38:01,696 --> 00:38:04,866
to try and get some underwater shots
of these dolphins coming through.

512
00:38:05,563 --> 00:38:09,120
Holding fingers, fins,
crossing rostrums and blowholes

513
00:38:09,329 --> 00:38:10,830
and flukes and flippers
and hands and feet.

514
00:38:11,122 --> 00:38:12,916
Everything we can cross, we're crossing.

515
00:38:14,626 --> 00:38:16,753
NARRATOR:
Roger dives into the clear shallows

516
00:38:16,961 --> 00:38:18,046
of the beach break.

517
00:38:21,382 --> 00:38:25,094
And soon, an enthusiastic
dolphin pod approaches.

518
00:38:26,721 --> 00:38:29,224
ROGER: When I got in the water
with the dolphins for the first time,

519
00:38:29,682 --> 00:38:32,685
there's this kind of strange jostling
back flexing behavior.

520
00:38:32,852 --> 00:38:36,773
Now, whether that was some social,
you know, interaction, I'm not sure.

521
00:38:37,106 --> 00:38:39,526
And I've never seen this before
anywhere else in the world.

522
00:38:43,655 --> 00:38:46,908
NARRATOR: As luck would have it,
with Roger now in amongst the pod,

523
00:38:47,909 --> 00:38:50,036
a set of waves finally comes in.

524
00:38:51,454 --> 00:38:54,040
And our lead actors are in business.

525
00:38:56,292 --> 00:38:58,545
ROGER:
The speed that came through was amazing.

526
00:38:59,546 --> 00:39:03,341
You actually see the way
they are using the energy of the wave

527
00:39:03,508 --> 00:39:05,927
to gain the momentum.
They're riding the pressure wave.

528
00:39:06,302 --> 00:39:08,596
And then you see them turn,
sort of build up speed,

529
00:39:08,763 --> 00:39:10,306
and then they bank left.

530
00:39:10,640 --> 00:39:13,059
And it's that pressure that shoots them
out the back of the wave.

531
00:39:13,351 --> 00:39:16,229
And it was just marvelous
to be in amongst all of that.

532
00:39:16,521 --> 00:39:18,606
It was just such a bonus.

533
00:39:20,774 --> 00:39:21,942
NARRATOR: But soon,

534
00:39:22,076 --> 00:39:24,454
the swell begins
to get dangerous for Roger.

535
00:39:24,737 --> 00:39:25,905
Time to get out.

536
00:39:28,575 --> 00:39:30,368
At last, surf is up.

537
00:39:30,869 --> 00:39:33,246
And with it, more dolphins.

538
00:39:33,663 --> 00:39:35,248
Hello, do you read me?

539
00:39:35,373 --> 00:39:38,293
There's quite a lot of dolphins
that are moving for the surf zone.

540
00:39:38,668 --> 00:39:41,838
So, yeah, looking very strong.
I think we're going to get something.

541
00:39:42,338 --> 00:39:43,423
Come on down.

542
00:39:45,466 --> 00:39:49,137
NARRATOR: Finally,
it's action stations for Jamie's team.

543
00:39:53,600 --> 00:39:54,642
JAMIE: Dolphins in the wave.

544
00:39:55,268 --> 00:39:58,646
NARRATOR: Carl must maneuver his boat
skillfully inside the surf zone...

545
00:40:00,106 --> 00:40:02,567
and get Jamie into the best
possible position.

546
00:40:04,652 --> 00:40:06,321
JAIMIE: You have to outrun the wave.

547
00:40:06,821 --> 00:40:08,948
But then, at certain point,
you have to get out, which means

548
00:40:09,157 --> 00:40:10,742
going over the top
of the 15-foot wave,

549
00:40:10,950 --> 00:40:12,535
so there's a 15-foot drop
in the back of it.

550
00:40:12,660 --> 00:40:15,914
NARRATOR: As they battle the waves,
Carl must also guide Jamie to where

551
00:40:16,214 --> 00:40:17,840
the dolphins might leap out.

552
00:40:18,700 --> 00:40:19,784
Watch out. There they go.

553
00:40:22,003 --> 00:40:23,922
CARL:
Yeah. So, we got in the face of that wave.

554
00:40:26,466 --> 00:40:28,092
JAMIE: Technically, it's very tricky to be

555
00:40:28,217 --> 00:40:30,053
tight on a dolphin
that's swimming through a wave whilst

556
00:40:30,403 --> 00:40:32,867
you're driving the other way
at high speed.

557
00:40:35,725 --> 00:40:37,727
NARRATOR:
But it finally starts to pay off

558
00:40:38,292 --> 00:40:42,106
as Jamie captures wave after wave
of dolphin magic.

559
00:40:51,574 --> 00:40:53,576
JAMIE: It's the most exciting,
dynamic thing that I've done.

560
00:41:03,836 --> 00:41:07,048
NARRATOR: But Carl mustn't get caught
too far in front of the waves.

561
00:41:07,966 --> 00:41:11,302
If they begin to crest,
they can easily flip his boat.

562
00:41:12,637 --> 00:41:14,722
This is where Roger and Paris come in.

563
00:41:15,798 --> 00:41:18,092
-Time to deploy the jet ski.
-Yeah. Let's go.

564
00:41:18,351 --> 00:41:20,228
ROGER: It was the first time
that I've ever attempted

565
00:41:20,395 --> 00:41:22,063
to film dolphins from a jet ski.

566
00:41:22,438 --> 00:41:24,315
But what we hoped for was just to get

567
00:41:24,399 --> 00:41:26,901
one or two unique shots
in front of the wave.

568
00:41:27,193 --> 00:41:30,738
Those waves were big, you know.
It's a big wave.

569
00:41:31,698 --> 00:41:33,908
You've got a really skilled pilot
trying to get you

570
00:41:34,075 --> 00:41:35,702
into these really difficult situations

571
00:41:35,868 --> 00:41:38,538
where that wave could just swamp you
at any time.

572
00:41:39,288 --> 00:41:40,581
Paris was just astounding.

573
00:41:40,832 --> 00:41:44,419
He was able to just anticipate
how the wave was going to break.

574
00:41:45,294 --> 00:41:46,671
I'll never forget that moment where

575
00:41:46,888 --> 00:41:49,098
there was a really nice break
coming through,

576
00:41:49,465 --> 00:41:51,050
really good-sized pod of dolphins.

577
00:41:52,552 --> 00:41:54,303
We really had a go at one wave...

578
00:41:56,305 --> 00:41:59,600
and then I just remember seeing dolphins
in the face of the wave.

579
00:42:01,476 --> 00:42:04,396
Paris has got to wait, wait, wait.
He's got to judge it.

580
00:42:06,088 --> 00:42:09,694
Just this, you know, wonderful image
of them all racing down the wave.

581
00:42:09,861 --> 00:42:12,989
And then, as that wave breaks,
he's going to accelerate us out of there.

582
00:42:13,448 --> 00:42:14,824
And it happened so quickly.

583
00:42:21,664 --> 00:42:24,000
ROGER: It was really the shot
that I was so hoping to get.

584
00:42:28,796 --> 00:42:31,174
This is so exhilarating.
You've been waiting for so long, you know,

585
00:42:31,340 --> 00:42:33,593
you're sitting,
you're waiting for, like, days and days.

586
00:42:33,760 --> 00:42:36,137
And then suddenly, you know,
the set's here and everything's right.

587
00:42:36,345 --> 00:42:38,264
And in the next minute, you know,
Stevie just picks up,

588
00:42:38,431 --> 00:42:40,475
he goes, "Pick up the things,"
and, bang, you know, on it,

589
00:42:40,641 --> 00:42:42,894
exactly as we predicted,
just jumping down the face,

590
00:42:43,352 --> 00:42:45,146
surfing the wave together,
jumping out the back.

591
00:42:45,646 --> 00:42:47,523
ROGER: I mean, it's fantastic, yeah.

592
00:42:49,067 --> 00:42:52,779
NARRATOR: Our filmmakers have captured
some incredible, dynamic scenes

593
00:42:53,045 --> 00:42:54,839
of dolphins letting loose.

594
00:42:56,866 --> 00:42:59,952
But a dolphin's daily life
is not all fun and games.

595
00:43:02,914 --> 00:43:04,499
They also need to find food,

596
00:43:05,291 --> 00:43:07,251
not often found on the reef itself.

597
00:43:12,465 --> 00:43:15,343
And one of the most amazing
dolphin feeding grounds

598
00:43:15,968 --> 00:43:17,178
is in the Bahamas.

599
00:43:18,805 --> 00:43:20,389
Onboard the Dolphin Dream,

600
00:43:20,657 --> 00:43:24,060
our Bahamian team are relying
on skipper Scott Smith,

601
00:43:24,477 --> 00:43:27,980
a veteran dolphin finder,
to take them to the action.

602
00:43:30,817 --> 00:43:32,944
Joining the crew
for this portion of the story

603
00:43:33,469 --> 00:43:35,346
is cinematographer Paul Atkins

604
00:43:35,905 --> 00:43:40,576
a marine biologist and dolphin specialist
who's filmed them all over the world.

605
00:43:51,170 --> 00:43:53,840
PAUL: I've been filming dolphins
and whales for over 30 years.

606
00:43:54,924 --> 00:43:57,510
So, I've filmed bottlenose dolphins
in the Bahamas before.

607
00:43:58,302 --> 00:44:01,139
I always look for an opportunity
to go back.

608
00:44:02,306 --> 00:44:04,892
It's just always a thrill
to get in the water

609
00:44:05,353 --> 00:44:07,353
and to see animals that I'm familiar with.

610
00:44:09,480 --> 00:44:12,024
And sometimes,
I feel like they remember me,

611
00:44:12,275 --> 00:44:14,443
that they're coming up to me
and saying hello.

612
00:44:15,695 --> 00:44:18,072
Eventually, when they stop paying
attention to you,

613
00:44:18,239 --> 00:44:20,408
and then you become a part of their tribe.

614
00:44:20,575 --> 00:44:23,870
And it's an extraordinary experience
when you can just travel with them

615
00:44:24,120 --> 00:44:26,080
and see what they do.

616
00:44:28,457 --> 00:44:32,587
NARRATOR: Paul is here to capture
dolphins hunting in a very special way.

617
00:44:35,673 --> 00:44:38,718
They use a type of sonar
called echolocation,

618
00:44:39,635 --> 00:44:41,804
which works kind of like x-ray vision.

619
00:44:47,685 --> 00:44:52,106
They emit a series of rapid-fire clicks
that bounce off hidden objects,

620
00:44:53,107 --> 00:44:55,735
allowing them to locate food
beneath the sand...

621
00:44:59,363 --> 00:45:01,490
food like razorfish.

622
00:45:06,787 --> 00:45:09,415
PAUL:
When you're with a group of dolphins,

623
00:45:09,749 --> 00:45:13,169
you feel privileged
to be witnessing their culture.

624
00:45:15,671 --> 00:45:20,509
Dolphins are one of the few animals
besides humans and great apes

625
00:45:20,801 --> 00:45:23,095
that actually have been shown
to have culture.

626
00:45:23,526 --> 00:45:26,641
And that culture is based
on ways of finding food.

627
00:45:37,485 --> 00:45:38,527
NARRATOR: Around the world,

628
00:45:38,945 --> 00:45:41,739
dolphins have developed
different feeding strategies

629
00:45:42,156 --> 00:45:43,741
depending on their habitat.

630
00:45:45,201 --> 00:45:49,163
And some of them involve
extraordinary levels of teamwork.

631
00:45:53,584 --> 00:45:56,212
These shallow tidal mudflats in Florida

632
00:45:56,472 --> 00:46:00,322
are a rich feeding ground
for many marine and coastal animals.

633
00:46:02,009 --> 00:46:04,053
And with its great abundance of fish,

634
00:46:04,303 --> 00:46:09,100
it has given rise to a unique
and spectacular dolphin hunting technique

635
00:46:09,809 --> 00:46:11,644
known as mud ringing.

636
00:46:17,525 --> 00:46:19,193
Scientist, Laura Engleby,

637
00:46:19,652 --> 00:46:23,781
has brought cinematographer
Jamie McPherson onto these tidal flats

638
00:46:24,031 --> 00:46:26,617
in search of this remarkable phenomenon.

639
00:46:29,870 --> 00:46:32,290
For Jamie, it may not be as heart-stopping

640
00:46:32,456 --> 00:46:34,792
as filming dolphins surfing the big waves,

641
00:46:35,501 --> 00:46:37,086
but it is just as difficult.

642
00:46:41,716 --> 00:46:44,010
-JAMIE: Oh, damn it.
-

643
00:46:44,337 --> 00:46:46,887
JAMIE: From the boat, it's tricky because
you have to work out where they are.

644
00:46:47,346 --> 00:46:48,931
The camera's right on sea level.

645
00:46:49,482 --> 00:46:51,067
You only see them when they surface.

646
00:46:51,267 --> 00:46:52,476
So, you see the fins occasionally.

647
00:46:52,727 --> 00:46:54,603
You're trying to work out
where they're going to go.

648
00:46:54,870 --> 00:46:56,247
It's very hard to coordinate that.

649
00:46:56,856 --> 00:46:59,275
It's very tricky to be in the right place
at the right time.

650
00:47:02,361 --> 00:47:05,239
NARRATOR: Suddenly, the dolphins
look like they are teaming up

651
00:47:05,614 --> 00:47:07,033
and coordinating their efforts.

652
00:47:07,455 --> 00:47:08,605
WOMAN:
No, Jamie, now they're to the right.

653
00:47:08,951 --> 00:47:10,619
-To the right.
-JAMIE: Coming where?

654
00:47:10,703 --> 00:47:12,079
-WOMAN 1: To your right.
-WOMAN 2: Right.

655
00:47:12,280 --> 00:47:14,105
WOMAN 1: See them?

656
00:47:15,458 --> 00:47:16,917
NARRATOR: They've started to hunt.

657
00:47:21,063 --> 00:47:24,108
Jamie zeroes in on the action
with his zoom lens.

658
00:47:29,764 --> 00:47:31,223
JAMIE: Well, you see a lot of splashing.

659
00:47:33,601 --> 00:47:36,687
They don't put their heads up to catch
the fish until the very last second.

660
00:47:37,396 --> 00:47:40,232
The dolphins still have to try and catch
fish that's flying through the air.

661
00:47:40,566 --> 00:47:42,735
So, to see the look on their faces
and see how quick they are

662
00:47:42,818 --> 00:47:45,863
at reacting to the fish that are flying
really immerses you in it.

663
00:47:47,031 --> 00:47:49,158
But to understand the behavior
and really see what was going on,

664
00:47:49,825 --> 00:47:51,202
we had to get in the air.

665
00:48:02,972 --> 00:48:06,183
NARRATOR: Spotting dolphin pods
across these vast mudflats

666
00:48:06,475 --> 00:48:08,853
is much easier in a helicopter.

667
00:48:10,137 --> 00:48:11,639
I see some dolphins right down here.

668
00:48:11,847 --> 00:48:15,059
NARRATOR: Each day,
dolphins travel up these tidal channels

669
00:48:15,309 --> 00:48:17,269
into dangerously shallow waters,

670
00:48:18,229 --> 00:48:21,399
lured here by the sheer bounty
of fish to be had.

671
00:48:23,042 --> 00:48:24,919
It looks like they're in
really shallow water there.

672
00:48:27,029 --> 00:48:29,031
NARRATOR:
It's so shallow here at low tide,

673
00:48:29,323 --> 00:48:31,242
they often have to swim on their sides.

674
00:48:36,789 --> 00:48:40,626
This one certainly seems
to be having fun hunting in the sea grass.

675
00:48:41,085 --> 00:48:43,587
What are you doing?

676
00:48:48,384 --> 00:48:50,219
NARRATOR:
But this is not the hunting behavior

677
00:48:50,302 --> 00:48:51,512
the crew are looking for.

678
00:48:52,430 --> 00:48:54,014
So, they continue their search.

679
00:48:54,498 --> 00:48:56,225
-PILOT: Yeah, I'm bringing it around.
-LAURA: All right.

680
00:48:56,308 --> 00:48:57,685
-PILOT: Yeah, preparing...
-LAURA: Yeah...

681
00:48:57,768 --> 00:48:59,073
PILOT: ...turning the nose right now...

682
00:48:59,186 --> 00:49:00,479
JAMIE: Yeah, I will. So, we'll just

683
00:49:00,604 --> 00:49:02,523
come back to these guys
if we can't find anything else.

684
00:49:03,149 --> 00:49:04,150
NARRATOR: Nearby,

685
00:49:04,316 --> 00:49:06,944
another group of dolphins
reveal some of the risks

686
00:49:07,153 --> 00:49:09,196
of hunting in such shallow waters.

687
00:49:10,281 --> 00:49:13,242
-LAURA: Oh, they're definitely stranded.
-JAMIE: Yeah, they're definitely stranded.

688
00:49:14,535 --> 00:49:16,787
LAURA: Quite amazing. They made
a little mud hole for themselves.

689
00:49:17,872 --> 00:49:21,959
They have come around in tight circles
and have created a mud hole

690
00:49:22,209 --> 00:49:23,752
to where they can at least swim

691
00:49:24,003 --> 00:49:26,755
and not get sun burns
and not flip on their sides

692
00:49:26,881 --> 00:49:28,924
because the worse thing,
when they're stuck like that,

693
00:49:29,091 --> 00:49:32,511
is they can crush their internal organs
with their own body weight and overheat.

694
00:49:33,554 --> 00:49:35,890
JAMIE: It's horrible to see
'cause you can see they're stressed out,

695
00:49:36,015 --> 00:49:38,066
you can see they're worried,
and there's nothing you can do.

696
00:49:38,241 --> 00:49:40,352
You're in a helicopter flying around
and no one can help them.

697
00:49:43,564 --> 00:49:45,441
NARRATOR:
Laura knows the tide is rising,

698
00:49:45,691 --> 00:49:47,693
so the dolphins will soon be freed.

699
00:49:49,778 --> 00:49:52,281
And before long, they spot something.

700
00:49:53,032 --> 00:49:54,158
Mud clouds.

701
00:49:57,077 --> 00:50:00,623
As they approach, they can see
the dolphins are definitely hunting.

702
00:50:01,582 --> 00:50:04,335
LAURA: From the air,
it offers a whole different perspective

703
00:50:04,502 --> 00:50:05,753
of what's going on.

704
00:50:06,170 --> 00:50:09,757
They're clearly chasing some prey,
but this is a feeding strategy

705
00:50:09,924 --> 00:50:11,675
that hasn't been documented
in the literature

706
00:50:11,842 --> 00:50:13,969
that we're just now,
through this aerial footage,

707
00:50:14,136 --> 00:50:16,472
able to really see what they're doing.

708
00:50:17,848 --> 00:50:20,017
NARRATOR:
But this still isn't the hunting behavior

709
00:50:20,184 --> 00:50:21,435
they've come here to film.

710
00:50:24,563 --> 00:50:26,106
Then, finally,

711
00:50:26,689 --> 00:50:28,775
Jamie spots what they've been looking for.

712
00:50:29,443 --> 00:50:34,406
This dolphin beats up the mud
with its fluke, creating a perfect circle.

713
00:50:36,158 --> 00:50:37,326
A mud ring.

714
00:50:38,118 --> 00:50:40,037
Aww. Wow. Aww.

715
00:50:40,287 --> 00:50:41,956
NARRATOR: This technique in itself...

716
00:50:42,540 --> 00:50:45,000
showcases
the dolphin's remarkable intelligence

717
00:50:45,751 --> 00:50:50,172
as they use the muddy substrate
to form the perfect fishing net.

718
00:50:53,383 --> 00:50:55,760
I see they've got
a shoal of fish surrounded.

719
00:50:56,053 --> 00:50:57,555
Yeah, it's really nice.

720
00:50:58,055 --> 00:51:01,183
NARRATOR: Other dolphins have
corralled the shoal of fish into the ring.

721
00:51:02,309 --> 00:51:04,895
And the entrapped fish,
in trying to escape,

722
00:51:05,145 --> 00:51:07,439
leap straight into their waiting mouths.

723
00:51:21,245 --> 00:51:23,664
Absolutely perfect,
there's a whole shoal of fish.

724
00:51:24,415 --> 00:51:26,417
You can see the dolphins
trying to get around them.

725
00:51:29,461 --> 00:51:31,589
-Look at that, there.
-

726
00:51:31,922 --> 00:51:34,091
-LAURA: That is amazing.
-JAMIE: That's pretty amazing.

727
00:51:39,471 --> 00:51:41,890
JAMIE: I've never seen anything
that coordinated.

728
00:51:42,516 --> 00:51:44,643
And they're definitely working together
and communicating

729
00:51:45,019 --> 00:51:46,729
to better coordinate the ring

730
00:51:46,937 --> 00:51:48,939
and make the fish leap
and land where dolphins are waiting.

731
00:51:49,106 --> 00:51:51,692
-It's, yeah, an amazing display.
-

732
00:52:17,635 --> 00:52:19,511
NARRATOR:
The team's patience has paid off.

733
00:52:20,621 --> 00:52:22,623
They've finally captured on film

734
00:52:23,057 --> 00:52:27,186
this remarkable cooperative
hunting strategy of bottlenose dolphins.

735
00:52:32,232 --> 00:52:34,818
In much deeper waters
off the coast of Hawaii,

736
00:52:35,944 --> 00:52:37,946
our whale team have returned to film

737
00:52:38,113 --> 00:52:40,491
a great gathering of male humpbacks.

738
00:52:43,077 --> 00:52:44,078
But this gathering

739
00:52:44,244 --> 00:52:47,289
is not in the same cooperative spirit
as the dolphins.

740
00:52:48,499 --> 00:52:49,667
Quite the opposite.

741
00:52:51,043 --> 00:52:53,462
An intense competition is brewing.

742
00:52:55,381 --> 00:52:57,758
Here, they gather in the greatest numbers

743
00:52:58,008 --> 00:53:01,804
to take part
in the most spectacular battle in nature.

744
00:53:11,095 --> 00:53:13,440
Back on the Luckey Strike,
Tad has now teamed up

745
00:53:13,731 --> 00:53:16,234
with Paul Atkins
to film this great ritual.

746
00:53:17,194 --> 00:53:21,907
They are following a female humpback
who has a number of males in hot pursuit.

747
00:53:23,492 --> 00:53:26,620
PAUL: There's definitely an air
of excitement and tension when you're

748
00:53:26,787 --> 00:53:28,956
headed out to film one of these battles.

749
00:53:29,206 --> 00:53:31,125
You're never quite sure
what's going to happen.

750
00:53:32,126 --> 00:53:34,795
They're going really fast
at eleven o'clock.

751
00:53:39,800 --> 00:53:43,303
NARRATOR: Professor Joe Mobley
is documenting the activity from the bow.

752
00:53:46,223 --> 00:53:50,436
And as the boat catches up with the pod,
things really start to heat up.

753
00:53:53,021 --> 00:53:55,399
The battle is about to commence.

754
00:54:02,114 --> 00:54:04,074
The males begin to chase one another.

755
00:54:14,960 --> 00:54:16,545
It's a pretty fast-moving pod.

756
00:54:23,260 --> 00:54:26,805
As Paul begin to film
some spectacular surface behavior,

757
00:54:27,389 --> 00:54:29,975
more and more whales join the competition.

758
00:54:33,395 --> 00:54:36,106
All these challengers
are racing to catch up

759
00:54:36,315 --> 00:54:38,484
and displace the current front-runner,

760
00:54:39,276 --> 00:54:42,738
wanting to become the ultimate champion.

761
00:54:52,289 --> 00:54:55,417
Out in front,
the female is setting the pace.

762
00:54:59,797 --> 00:55:02,966
But this surface view does not reveal
the whole combat,

763
00:55:03,467 --> 00:55:05,844
as Joe has speculated for many years.

764
00:55:06,887 --> 00:55:10,307
JOE: The frustrating thing is I'm bound
to the above-surface world,

765
00:55:10,682 --> 00:55:12,643
where we're limited to probably
less than ten percent

766
00:55:12,810 --> 00:55:13,894
of their total behavior.

767
00:55:14,186 --> 00:55:16,396
You know, most of what's important
is going down below.

768
00:55:19,691 --> 00:55:21,068
Looks good for pole cam, right?

769
00:55:21,310 --> 00:55:22,311
Go ahead.

770
00:55:22,611 --> 00:55:24,071
We're going to give it a try.

771
00:55:25,447 --> 00:55:27,783
JOE: So, increasingly, I've been
relying on opportunities like this

772
00:55:27,991 --> 00:55:31,253
to work with film crews
with their high-tech equipment.

773
00:55:31,370 --> 00:55:33,205
And those kinds of instruments
basically give us

774
00:55:33,372 --> 00:55:35,582
a whale's eye view.
It puts us in their world.

775
00:55:35,874 --> 00:55:37,835
Much more likely to answer
the kinds of questions

776
00:55:38,210 --> 00:55:40,254
that we've been asking for decades now.

777
00:55:41,813 --> 00:55:42,940
TAD: Okay, you've got it?

778
00:55:43,131 --> 00:55:45,884
PAUL: So, we designed the granddaddy
of all pole cams,

779
00:55:46,218 --> 00:55:47,803
and this had never been tried before.

780
00:55:48,428 --> 00:55:49,471
MAN: Okay, I got it.

781
00:55:49,680 --> 00:55:53,308
PAUL: And the pole cam system
has to be beefy and sturdy enough

782
00:55:53,559 --> 00:55:57,145
to withstand moving through water
at four to five knots,

783
00:55:57,437 --> 00:55:58,939
sometimes six knots.

784
00:56:01,316 --> 00:56:04,319
NARRATOR: Paul hopes to capture
a unique underwater perspective

785
00:56:04,486 --> 00:56:06,196
of this great contest.

786
00:56:08,448 --> 00:56:11,118
On top deck,
he prepares the viewing monitor.

787
00:56:12,786 --> 00:56:15,622
As the boat races to catch up
with the charging giants,

788
00:56:16,456 --> 00:56:19,626
skipper Tad must get his boat
right alongside them.

789
00:56:28,343 --> 00:56:29,636
PAUL: Okay, there's two whales.

790
00:56:30,387 --> 00:56:32,180
Now there's three whales in the frame.

791
00:56:33,065 --> 00:56:35,567
Okay, there's one
dead center in the frame.

792
00:56:36,101 --> 00:56:37,561
This is great position, Tad.

793
00:56:38,729 --> 00:56:42,190
Oh, he's coming up right here,
right here, this is good.

794
00:56:43,983 --> 00:56:45,752
Stay in and let these guys catch up.

795
00:56:47,195 --> 00:56:49,823
NARRATOR: By combining
Paul's underwater and surface filming

796
00:56:51,408 --> 00:56:53,493
with aerial footage by helicopter...

797
00:56:54,786 --> 00:56:57,205
PAUL: Oh, this is great, Tad. Hold this.

798
00:56:57,827 --> 00:57:02,044
...he starts to reveal the intensity
of this battle like never before.

799
00:57:05,047 --> 00:57:07,841
Okay, there's one below that's coming.
This is great position, Tad.

800
00:57:08,508 --> 00:57:12,137
PAUL: And he's coming up right here,
right here, this is good.

801
00:57:15,432 --> 00:57:16,433
Wow.

802
00:57:16,850 --> 00:57:17,851
Geez.

803
00:57:23,065 --> 00:57:25,108
NARRATOR:
All the whales dive down into the deep.

804
00:57:30,238 --> 00:57:31,490
PAUL: Diving, diving.

805
00:57:33,033 --> 00:57:34,419
And there they go.

806
00:57:35,077 --> 00:57:37,287
Now, we can see them all
diving towards the bottom,

807
00:57:37,454 --> 00:57:38,914
going down about 200 feet.

808
00:57:40,499 --> 00:57:42,167
Sometimes it goes... so we can follow them

809
00:57:42,334 --> 00:57:43,919
straight down the bottom
and you see them.

810
00:57:44,169 --> 00:57:46,380
Looks like they're rubbing on the bottom
at 200 feet.

811
00:57:46,755 --> 00:57:48,256
If we could get a camera down there,

812
00:57:48,423 --> 00:57:50,550
we might find out
where's it's all really happening.

813
00:57:50,926 --> 00:57:53,971
Maybe that's where the actual mating
is occurring.

814
00:57:54,846 --> 00:57:56,056
-Who knows?
-Coming up.

815
00:57:56,223 --> 00:57:57,599
They're still stuck on us right here.

816
00:57:57,975 --> 00:58:00,352
NARRATOR:
Suddenly, erupting back up from the deep,

817
00:58:00,727 --> 00:58:03,772
the conflict resumes
at an even greater pace.

818
00:58:05,107 --> 00:58:06,817
Yeah, yeah, yeah, because this is...

819
00:58:07,442 --> 00:58:09,486
Yeah, this is really getting good.

820
00:58:10,988 --> 00:58:14,199
NARRATOR: Over 25 male whales
charge past the camera,

821
00:58:14,658 --> 00:58:16,785
blowing streams off aggressive bubbles.

822
00:58:17,536 --> 00:58:19,037
-PAUL: Lot of bubbles.
-MAN: Yeah.

823
00:58:19,496 --> 00:58:20,914
-PAUL: Tons of bubbles.
-MAN: Coming up.

824
00:58:29,881 --> 00:58:32,968
NARRATOR: Those in the rear
try to force the front-runners under,

825
00:58:34,011 --> 00:58:38,765
ruthlessly ramming them to slow them down
and take the lead nearest to the female.

826
00:58:43,020 --> 00:58:47,441
This is the most immense
ocean competition in nature.

827
00:58:52,195 --> 00:58:54,448
Finally, as the other males tire,

828
00:58:54,717 --> 00:58:57,826
the two fastest and strongest
take primary positions

829
00:58:59,327 --> 00:59:01,121
hot on the heels of the female.

830
00:59:13,967 --> 00:59:16,887
In the last moments,
a challenger lunges forward

831
00:59:17,154 --> 00:59:18,864
and forces his rival under...

832
00:59:21,641 --> 00:59:23,060
and out of the race...

833
00:59:24,853 --> 00:59:27,522
claiming his place as the victor.

834
00:59:34,821 --> 00:59:35,906
And they're gone.

835
00:59:37,908 --> 00:59:39,117
PAUL: And there they go.

836
00:59:43,622 --> 00:59:46,374
NARRATOR: This battle is finally over.

837
00:59:48,919 --> 00:59:52,297
One mighty humpback has fought
and won the right

838
00:59:52,589 --> 00:59:55,300
to be the protector of our lone female.

839
01:00:01,973 --> 01:00:05,018
Filming this magnificent event
was only possible

840
01:00:05,227 --> 01:00:08,855
because protection has allowed
whale societies to rebuild.

841
01:00:12,317 --> 01:00:16,071
Unfortunately,
such success stories are rare.

842
01:00:17,030 --> 01:00:18,406
And unlike the humpbacks,

843
01:00:19,074 --> 01:00:21,785
the populations
of our ocean's greatest predators

844
01:00:22,202 --> 01:00:23,620
are in huge decline.

845
01:00:29,000 --> 01:00:32,671
Over a hundred million sharks
are fished each year

846
01:00:33,421 --> 01:00:36,466
to satisfy the demands
of the shark finning industry.

847
01:00:38,468 --> 01:00:42,472
Giants like the tiger shark
are becoming increasingly rare.

848
01:00:44,474 --> 01:00:48,145
And their overblown reputation
as frightening and deadly predators

849
01:00:48,770 --> 01:00:50,147
has not helped them.

850
01:00:58,446 --> 01:01:01,283
Paul, however, having filmed sharks
for many years,

851
01:01:01,533 --> 01:01:04,619
knows they are nothing like
this cartoonish stereotype.

852
01:01:07,038 --> 01:01:09,833
The first time I saw sharks underwater,
what impressed me was

853
01:01:10,000 --> 01:01:13,461
how extraordinarily beautiful they are,
how graceful they are,

854
01:01:13,837 --> 01:01:18,008
how perfectly adapted that
they're swimming and how agile they are.

855
01:01:18,675 --> 01:01:21,094
And then, the next thing
that impresses you about sharks,

856
01:01:21,386 --> 01:01:23,430
because you grow up with all of this fear,

857
01:01:23,638 --> 01:01:25,807
is they don't seem
to be threatening you.

858
01:01:26,224 --> 01:01:27,893
PAUL: They don't seem to be that scary.

859
01:01:33,607 --> 01:01:35,192
When tiger sharks show up...

860
01:01:36,318 --> 01:01:38,403
their presence
kind of dominates the scene.

861
01:01:38,620 --> 01:01:41,456
Pretty much, you have your attention
on the tiger shark,

862
01:01:41,907 --> 01:01:43,116
and you never turn your back on it,

863
01:01:43,200 --> 01:01:46,411
because they tend to know
which direction you're looking at,

864
01:01:47,078 --> 01:01:49,206
and they tend to want to come up
behind you.

865
01:01:54,377 --> 01:01:57,172
But they like to test,
they like to see what you are.

866
01:01:57,339 --> 01:02:01,384
And part of that testing
can be pushing its nose into you.

867
01:02:05,222 --> 01:02:07,891
And what you can do
is just put your hand on its nose

868
01:02:08,016 --> 01:02:09,726
and just gently push them away.

869
01:02:10,185 --> 01:02:13,188
PAUL: What other predator on land
could you do that with?

870
01:02:13,438 --> 01:02:16,733
If you did it with bears
that were feeding, or lions, or tigers,

871
01:02:17,275 --> 01:02:18,735
you'd probably get mauled.

872
01:02:19,361 --> 01:02:22,656
And yet, here with one of the biggest,
baddest, predators on the planet,

873
01:02:23,114 --> 01:02:25,116
in terms of the way we feel about them,

874
01:02:25,450 --> 01:02:27,744
and it's perfectly safe to do that, so...

875
01:02:39,881 --> 01:02:42,676
NARRATOR: Sharks are not only
misunderstood by humans,

876
01:02:43,426 --> 01:02:47,514
but their important role in maintaining
a well-balanced ocean ecosystem

877
01:02:48,265 --> 01:02:49,683
is often overlooked.

878
01:02:55,647 --> 01:02:58,650
A healthy coral reef has many sharks,

879
01:02:59,025 --> 01:03:03,321
but in today's oceans, these reefs
are increasingly hard to find.

880
01:03:06,992 --> 01:03:09,494
Underwater cinematographer,
Denis Lagrange,

881
01:03:09,744 --> 01:03:13,540
has known for years
about one of the last strongholds on Earth

882
01:03:14,045 --> 01:03:16,849
for large gatherings of grey reef sharks.

883
01:03:17,544 --> 01:03:22,048
He's in French Polynesia, preparing
to dive these shark-infested waters.

884
01:03:30,265 --> 01:03:34,686
On an incoming tide, hundreds
of reef sharks school in this channel.

885
01:03:44,446 --> 01:03:48,116
Like Paul, Denis has no fear
of these apex predators,

886
01:03:48,533 --> 01:03:51,036
for he knows he is not on their menu.

887
01:03:52,746 --> 01:03:55,915
DENIS: For me, sharks are
one of the most of incredible creature

888
01:03:56,082 --> 01:03:58,251
in the ocean, and you really feel it.

889
01:04:02,881 --> 01:04:05,884
And when we have
all these sharks gather together

890
01:04:06,217 --> 01:04:08,011
and they're really concentrated,

891
01:04:08,428 --> 01:04:10,180
it's an amazing spectacle,

892
01:04:10,347 --> 01:04:14,021
and French Polynesia is the last place,
I think, in the world,

893
01:04:14,196 --> 01:04:15,821
where you can see that.

894
01:04:18,521 --> 01:04:22,150
We try to justify why sharks
should be saved and not killed,

895
01:04:22,484 --> 01:04:26,821
try to fight against shark finning,
but I think it's important to repeat it

896
01:04:27,280 --> 01:04:29,366
because they are
at the top of the food chain.

897
01:04:29,949 --> 01:04:32,577
They're cleaning the reef
of all natural sickness.

898
01:04:52,514 --> 01:04:56,935
So, if you have no predators,
the reef will just not be in good shape.

899
01:04:57,227 --> 01:04:58,395
It's a reality.

900
01:04:59,437 --> 01:05:01,314
We have to try our best
to protect the shark.

901
01:05:01,940 --> 01:05:04,859
And French Polynesia,
it's one of the only country in the world

902
01:05:05,235 --> 01:05:07,821
who really protect the shark.
It's written in the law.

903
01:05:08,154 --> 01:05:11,241
You're not allowed to kill sharks,
you're not allowed to fish sharks.

904
01:05:12,784 --> 01:05:15,120
NARRATOR: And the protection of sharks
in these waters

905
01:05:15,286 --> 01:05:18,289
allows them to fulfil their role
as vital hunters.

906
01:05:20,458 --> 01:05:22,961
But most sharks don't hunt
during daylight hours.

907
01:05:23,420 --> 01:05:26,548
The serious hunting action occurs
after dark.

908
01:05:28,341 --> 01:05:31,386
So, Denis's next dive
would be a much greater challenge,

909
01:05:32,262 --> 01:05:36,307
filming sharks hunting at night
for his very first time.

910
01:05:39,894 --> 01:05:42,397
They put on special chainmail shark suits

911
01:05:42,772 --> 01:05:46,109
designed to stop a reef shark's teeth
from puncturing the skin.

912
01:05:48,278 --> 01:05:50,947
Sharks don't often
intentionally bite humans.

913
01:05:51,739 --> 01:05:55,618
But in the heat of a feeding frenzy,
it's wise to take precautions.

914
01:05:57,120 --> 01:06:00,457
We expect a lot of shark action tonight.

915
01:06:02,333 --> 01:06:03,751
I hope we will survive.

916
01:06:04,335 --> 01:06:06,129
-MAN: Should we go now?
-We should go.

917
01:06:06,504 --> 01:06:07,505
Yeah.

918
01:06:09,424 --> 01:06:11,092
-MAN: Are we good?
-Are we good?

919
01:06:11,593 --> 01:06:12,677
Yeah.

920
01:06:15,763 --> 01:06:18,391
NARRATOR:
It's more like a special forces operation.

921
01:06:19,517 --> 01:06:20,727
And it needs to be.

922
01:06:39,662 --> 01:06:41,831
NARRATOR:
A few sharks appear straight away.

923
01:06:44,918 --> 01:06:46,503
Then the numbers build quickly.

924
01:06:54,260 --> 01:06:56,137
DENIS:
When you first dive down to the reef

925
01:06:56,554 --> 01:06:59,682
and you see this amazing
number of sharks altogether,

926
01:07:00,600 --> 01:07:01,935
you feel a little scared.

927
01:07:09,734 --> 01:07:11,361
NARRATOR: The surface team is anxious.

928
01:07:11,986 --> 01:07:14,572
They can see the sharks
amassing from above.

929
01:07:16,241 --> 01:07:20,495
DENIS: We've never seen that before.
Daytime, the shark kind of lazy,

930
01:07:20,703 --> 01:07:22,872
but as soon as you're diving
at night with them,

931
01:07:23,498 --> 01:07:25,917
you really see how powerful they can be.

932
01:07:32,298 --> 01:07:34,926
NARRATOR: While the fish
remain hidden, they are safe.

933
01:07:41,349 --> 01:07:43,268
But a nervous reef fish breaks cover...

934
01:07:44,519 --> 01:07:46,229
and the feeding frenzy is on.

935
01:07:47,355 --> 01:07:50,316
DENIS: To be eaten by a shark
is a really big issue.

936
01:07:50,567 --> 01:07:54,153
When you have hundreds of them
in front of you or coming right at you,

937
01:07:54,445 --> 01:07:56,990
they don't care about you,
they just want the fish.

938
01:08:20,054 --> 01:08:21,764
DENIS: No, no, no, no, no!

939
01:08:30,914 --> 01:08:32,775
On l'a fait! On l'a fait!

940
01:08:37,280 --> 01:08:38,656
No, but then you have to pay attention

941
01:08:38,740 --> 01:08:40,450
-to the little fish going between us.
-Oh là là,

942
01:08:40,575 --> 01:08:42,368
-yeah, yeah, yeah.
-"Get away, get away."

943
01:08:42,619 --> 01:08:45,455
When they're frenzy, you know,
there are a lot of them.

944
01:08:45,747 --> 01:08:48,958
DENIS: If they come to you,
I mean, they kick you down.

945
01:08:49,208 --> 01:08:52,920
I really felt it, you know,
a little fish went out of the coral,

946
01:08:53,129 --> 01:08:55,673
and they went on it,
and they don't care about you,

947
01:08:55,840 --> 01:08:57,216
you know, just going for the fish.

948
01:08:57,550 --> 01:09:01,638
It was like a river, water flowing.
And then afterwards, another image,

949
01:09:02,305 --> 01:09:05,308
he was the middle of the LA,
Los Angeles traffic.

950
01:09:05,433 --> 01:09:07,185
-MAN: You know, like in the movie?
-

951
01:09:08,686 --> 01:09:11,439
You know, the big turnaround
and, like, cars everywhere.

952
01:09:12,106 --> 01:09:15,735
Huh? Highway, but full of cars,
like big traffic jam,

953
01:09:15,902 --> 01:09:17,612
and this was Denis in the middle of that.

954
01:09:17,904 --> 01:09:20,114
-I went to LA...
-It was just like flowing,

955
01:09:20,865 --> 01:09:22,950
like water, sharks flowing around him.

956
01:09:26,037 --> 01:09:29,791
They've been around here,
they've been here for 400 million years.

957
01:09:30,667 --> 01:09:33,711
I mean, those species are like...
When you see them hunting,

958
01:09:34,253 --> 01:09:37,674
it's like, you know, okay,
evolution made them so powerful.

959
01:09:37,924 --> 01:09:39,092
It's like the top.

960
01:09:39,926 --> 01:09:42,261
When they hunt,
it's just like beautiful to watch.

961
01:09:42,720 --> 01:09:43,721
Beautiful.

962
01:09:53,439 --> 01:09:54,982
NARRATOR:
On our cinematographers' quest

963
01:09:55,233 --> 01:09:58,778
to share with you
a tiny glimpse into a dolphin's world,

964
01:09:59,779 --> 01:10:01,572
they visited some unique places,

965
01:10:02,281 --> 01:10:05,284
many of which
are some of the last examples

966
01:10:05,451 --> 01:10:07,495
of thriving ocean communities.

967
01:10:09,706 --> 01:10:12,041
Healthy coral reefs, rich in life,

968
01:10:12,375 --> 01:10:16,295
once fringed every landmass
across our tropical oceans...

969
01:10:17,588 --> 01:10:20,174
yet today, very few remain.

970
01:10:21,259 --> 01:10:23,636
We are killing them.

971
01:10:26,597 --> 01:10:28,850
Pollution and unsustainable fishing

972
01:10:29,225 --> 01:10:33,229
are just a few of the destructive
practices causing their demise.

973
01:10:44,490 --> 01:10:48,494
Sadly, during the three years it took
for the team to make this film,

974
01:10:49,078 --> 01:10:52,498
a third of the Great Barrier Reef
bleached and died.

975
01:10:55,710 --> 01:10:59,464
Without immediate action,
most scientists agree

976
01:10:59,714 --> 01:11:04,677
that almost all coral reefs
will be destroyed in just 50 years.

977
01:11:06,637 --> 01:11:09,015
Countless creatures will cease to exist.

978
01:11:11,184 --> 01:11:14,353
And our dolphins will have lost
their vital home.

979
01:11:18,983 --> 01:11:24,113
But there is hope,
with one of the simplest of solutions...

980
01:11:25,740 --> 01:11:26,824
protection.

981
01:11:29,786 --> 01:11:34,957
The best example,
the islands of Palau in Micronesia.

982
01:11:36,876 --> 01:11:40,171
Didier has come here
to film a very special event.

983
01:11:41,380 --> 01:11:45,468
DIDIER: So, when I knew I was going
to go to Palau, I was very excited

984
01:11:45,635 --> 01:11:47,011
because I have never been.

985
01:11:48,346 --> 01:11:52,600
When I first put my head in the water,
I realized how beautiful it was.

986
01:11:54,435 --> 01:11:57,271
It's that sort of place
where you have strong upwellings

987
01:11:57,563 --> 01:11:59,774
bringing rich water from the depths,

988
01:12:00,900 --> 01:12:02,068
very rich in nutrients.

989
01:12:02,443 --> 01:12:05,655
Makes a top-class reef, very rich in life,

990
01:12:06,096 --> 01:12:07,614
with all those fish everywhere.

991
01:12:08,825 --> 01:12:10,159
And not only the small ones.

992
01:12:10,952 --> 01:12:12,745
Giants and other predators...

993
01:12:15,248 --> 01:12:17,708
all kind of fish.
We have all the food chain.

994
01:12:19,669 --> 01:12:23,548
Mantas, hundreds of sharks,
everyone is here.

995
01:12:30,680 --> 01:12:32,056
NARRATOR: In 1998,

996
01:12:32,348 --> 01:12:35,768
everyone thought that this reef
might have been lost forever.

997
01:12:37,478 --> 01:12:40,690
An El Niño event had bleached
and killed the coral.

998
01:12:42,733 --> 01:12:45,778
But you-know-who stepped in to clean up...

999
01:12:47,321 --> 01:12:49,407
our trusty bumphead parrotfish.

1000
01:12:51,242 --> 01:12:54,203
And with the added help
of government-enforced protection...

1001
01:12:55,288 --> 01:12:57,498
the reef is now as good as new.

1002
01:13:06,607 --> 01:13:11,696
Not surprisingly, Palau is now famous
for its great fish gatherings.

1003
01:13:12,847 --> 01:13:17,435
Every full moon, all the bumpheads
gather at dawn to spawn.

1004
01:13:19,186 --> 01:13:23,441
This is the legendary spectacle
Didier has come here to film.

1005
01:13:32,533 --> 01:13:35,620
DIDIER: To film the bumpheads spawning
is a special event

1006
01:13:35,912 --> 01:13:38,748
because this is something I do
for the first time.

1007
01:13:40,458 --> 01:13:42,043
First, you see all those fish...

1008
01:13:44,013 --> 01:13:46,756
and it's not ten, 30,
it's hundreds of them.

1009
01:13:48,549 --> 01:13:51,719
They are big massive fish,
like 20, 30 kilos.

1010
01:13:53,971 --> 01:13:56,682
For a cameraman,
this is something unique.

1011
01:14:03,356 --> 01:14:06,359
NARRATOR: Didier must remain poised
and ready the whole time,

1012
01:14:07,109 --> 01:14:10,738
because the actual spawning event
could occur at any moment.

1013
01:14:12,114 --> 01:14:14,158
DIDIER: When they aggregate,
you are on the reef,

1014
01:14:14,700 --> 01:14:17,411
so you wait, you wait,
and all of a sudden,

1015
01:14:17,620 --> 01:14:19,664
they stop to go out in the blue,

1016
01:14:20,081 --> 01:14:22,291
and this is where the action will start.

1017
01:14:23,167 --> 01:14:24,377
This is where...

1018
01:14:24,710 --> 01:14:28,089
things get complicated because you have
to swim against the current,

1019
01:14:28,464 --> 01:14:31,300
and we can't compete with the fish.

1020
01:14:31,467 --> 01:14:33,052
You know, they are much faster than us.

1021
01:14:34,061 --> 01:14:38,182
When the first female comes to spawn,
then they will all come together.

1022
01:14:38,557 --> 01:14:41,018
They go up, swim up,
and all the males follow.

1023
01:14:41,185 --> 01:14:43,396
You have two, three, four,
sometimes up to ten.

1024
01:14:43,763 --> 01:14:47,099
And you have to be very reactive
because this is very fast.

1025
01:14:47,817 --> 01:14:49,694
Not missing any action.

1026
01:14:51,362 --> 01:14:55,741
NARRATOR: Millions of parrotfish eggs
are released into the warm ocean currents,

1027
01:14:56,075 --> 01:14:59,829
creating the next generation
of reef saviors.

1028
01:15:05,376 --> 01:15:08,087
In discovering these spectacles
across the world,

1029
01:15:08,963 --> 01:15:13,050
our filmmakers have also given us
a valuable insight

1030
01:15:13,384 --> 01:15:16,470
into how we can help our fragile oceans.

1031
01:15:21,058 --> 01:15:22,893
With international protection,

1032
01:15:23,561 --> 01:15:27,064
more places like Palau
would be able to recover...

1033
01:15:31,527 --> 01:15:34,739
creating a healthier,
more productive ocean.

1034
01:15:37,908 --> 01:15:40,578
One full of incredible characters...

1035
01:15:41,871 --> 01:15:44,415
-...that can continue to thrive

1036
01:15:45,124 --> 01:15:47,418
long into the future.
