00:00:34,576 --> 00:00:38,830
‎它们是地球上最接近外星生物的族群

3
00:00:41,499 --> 00:00:45,837
‎难怪头足动物家族
‎激发了我们的想象力

4
00:00:51,843 --> 00:00:54,054
‎它们有着外星人一般的外表

5
00:00:56,014 --> 00:00:58,600
‎伴有惊人的智慧

6
00:00:58,683 --> 00:00:59,934
‎独立能力

7
00:01:00,018 --> 00:01:01,895
‎以及创造能力

‎关于深海中这些

9
00:01:06,858 --> 00:01:10,070
‎稀有的传奇生物
‎还有很多有待人类探索

10
00:01:14,532 --> 00:01:18,286
‎比小说情节更离奇的动物

11

‎（加拿大 温哥华岛）

13
00:01:41,976 --> 00:01:47,649
‎高营养成分的水质 使得这里成为
‎地球上一片最丰饶的海域

14
00:01:51,319 --> 00:01:54,697
‎一个孕育新生命的绝佳之地

15

‎（水深：25米 水温：5摄氏度）

16
00:02:01,830 --> 00:02:03,540
‎藏匿在海浪之下的

17
00:02:05,917 --> 00:02:07,252
‎秘密世界里

18
00:02:11,798 --> 00:02:14,759
‎有10万颗宝贵的蛋卵

19
00:02:18,763 --> 00:02:22,016
‎每一颗都不比一粒稻米大

20
00:02:29,607 --> 00:02:32,986
‎六个月来 它们一直被妈妈

21
00:02:34,070 --> 00:02:34,904
‎精心照料

22
00:02:38,700 --> 00:02:41,077
‎一只巨型太平洋章鱼

23
00:02:42,287 --> 00:02:43,246
‎它的身体

24
00:02:44,164 --> 00:02:45,331
‎便是他们的堡垒

25
00:02:48,209 --> 00:02:50,378
‎它时刻让海水保持涌动

26
00:02:50,461 --> 00:02:53,214
‎以防自己的宝宝被海藻闷死

27
00:02:55,842 --> 00:02:57,135
‎每颗蛋卵里

28
00:02:57,844 --> 00:03:02,182
‎都有一个这种离奇生物的小小复制品

29
00:03:04,767 --> 00:03:05,894
‎八只手臂

30
00:03:08,313 --> 00:03:09,856
‎三颗心脏

31
00:03:11,316 --> 00:03:12,442
‎以及蓝色的血液

32
00:03:15,904 --> 00:03:21,034
‎最终 它们的重量
‎会是出生时的25万倍

33
00:03:23,077 --> 00:03:26,331
‎成为海洋中最狡猾的掠食者之一

34
00:03:29,959 --> 00:03:31,794
‎但很少有蛋卵走到那一步

35
00:03:42,222 --> 00:03:45,058
‎是时候离开安全的育婴室了

36
00:04:01,032 --> 00:04:03,785
‎妈妈最后呼出一口气

37
00:04:06,204 --> 00:04:09,624
‎这只章鱼宝宝便被抛到海流中

38
00:04:16,589 --> 00:04:18,716
‎它以后再也不会见到妈妈

39
00:04:27,308 --> 00:04:28,518
‎完全孤身一人

40
00:04:29,852 --> 00:04:31,729
‎生死全凭海洋定夺

41
00:04:43,866 --> 00:04:45,410
‎如果它能活下来

42
00:04:45,493 --> 00:04:46,786
‎就能在地球上

43
00:04:46,869 --> 00:04:51,833
‎最不可思议的动物家族中
‎占据一席之地

44
00:05:03,678 --> 00:05:05,138
‎存在于各个海域

45
00:05:07,181 --> 00:05:10,435
‎共有800多种章鱼

46
00:05:12,270 --> 00:05:13,104
‎鱿鱼

47
00:05:14,272 --> 00:05:15,732
‎和墨鱼

48
00:05:18,318 --> 00:05:19,736
‎它们都属于头足动物

49
00:05:22,947 --> 00:05:26,284
‎就是字面意思的“头和脚”

50
00:05:27,368 --> 00:05:29,579
‎因为它们构造独特

51
00:05:30,246 --> 00:05:33,166
‎肢体从脸部抽出

52
00:05:36,627 --> 00:05:39,589
‎但最早期的头足动物长这副模样

53
00:05:41,883 --> 00:05:42,884
‎像一只鹦鹉螺

54
00:05:45,261 --> 00:05:47,513
‎它的长相与其软体动物亲属相似

55
00:05:48,139 --> 00:05:49,140
‎也就是蜗牛

56
00:05:51,726 --> 00:05:55,813
‎五亿年来 它的长相没有发生变化

57
00:05:59,359 --> 00:06:04,447
‎虽然其他生物
‎都在以最惊人的方式进化

58
00:06:05,448 --> 00:06:07,450
‎它们丢掉了外壳

59
00:06:08,826 --> 00:06:12,121
‎变得更灵活 更轻巧

60
00:06:13,915 --> 00:06:17,835
‎能够探索曾经的禁忌之地

61
00:06:21,506 --> 00:06:22,757
‎它们液体一般的形体

62
00:06:22,840 --> 00:06:27,095
‎甚至能扛过深海毁灭性的水压

63
00:06:29,680 --> 00:06:32,058
‎但没有了外壳的保护

64
00:06:32,141 --> 00:06:34,268
‎头足动物变成了易受攻击的目标

65
00:06:36,354 --> 00:06:41,025
‎所以它们发展出了
‎一系列几乎超自然的能力

66
00:06:41,109 --> 00:06:42,402
‎以保证自身安全

67
00:06:48,866 --> 00:06:52,036
‎这在掠食者的海洋中至关重要

68
00:06:52,995 --> 00:06:58,084
‎（南非 开普半岛）

69
00:07:00,378 --> 00:07:04,340
‎（水深：5米 水温：15摄氏度）

70
00:07:06,509 --> 00:07:09,470
‎海洋可能会是一个令人畏惧的地方

71
00:07:11,848 --> 00:07:14,517
‎如果你只有火柴盒大小的话

72
00:07:17,937 --> 00:07:20,273
‎保持低调是有好处的

73
00:07:23,067 --> 00:07:26,028
‎但一条小墨鱼不肯能永远躲起来

74
00:07:31,534 --> 00:07:35,538
‎高新陈代谢率意味着
‎它总是处于饥饿状态

75
00:07:41,294 --> 00:07:43,754
‎它最喜爱的食物生活在浅滩

76
00:07:45,798 --> 00:07:47,925
‎就距离它20米远

77
00:07:54,265 --> 00:07:58,394
‎但如果你这么小只
‎那这段路程便漫长而艰险

78
00:08:02,815 --> 00:08:04,484
‎危机重重

79
00:08:11,240 --> 00:08:12,783
‎它游泳技术不错

80
00:08:14,410 --> 00:08:16,787
‎但鱼类速度更快

81
00:08:21,375 --> 00:08:23,461
‎而且它们还有敏锐的视觉

82
00:08:25,838 --> 00:08:30,510
‎但与环境融为一体是头足动物的特长

83
00:08:38,518 --> 00:08:40,186
‎狡猾的墨鱼

84
00:08:41,229 --> 00:08:44,065
‎进一步提升了自己的伪装技术

85
00:08:45,775 --> 00:08:47,777
‎它皮肤中的特殊肌肉

86
00:08:48,361 --> 00:08:54,158
‎长出了成千上万个
‎被称为“结节”的带刺瘤状物

87
00:08:56,410 --> 00:08:58,246
‎让它看起来就像海藻

88
00:09:04,043 --> 00:09:05,711
‎这一招貌似有用

89
00:09:10,258 --> 00:09:13,386
‎这不是它衣橱里的唯一一套服装

90
00:09:16,222 --> 00:09:20,142
‎就在短短的一秒之内
‎它能变换出任意一种造型

91
00:09:27,233 --> 00:09:28,359
‎蜗牛

92
00:09:34,240 --> 00:09:35,074
‎珊瑚

93
00:09:38,869 --> 00:09:39,870
‎或石块

94
00:09:47,044 --> 00:09:50,506
‎头足动物惊人的色彩变换能力

95
00:09:51,966 --> 00:09:54,343
‎要拜它们的色素细胞所赐

96
00:09:56,137 --> 00:10:00,975
‎好几百万个充满色素的像素状细胞

97
00:10:01,767 --> 00:10:06,105
‎它们能像气球那样变大缩小

98
00:10:10,943 --> 00:10:14,113
‎以迅速变换颜色

99
00:10:21,996 --> 00:10:26,500
‎这使得墨鱼能在一秒瞬息之内
‎完美地与背景融为一体

100
00:10:33,966 --> 00:10:37,094
‎头足动物以在所有物种中

101
00:10:38,679 --> 00:10:43,100
‎最精巧的伪装技术
‎让变色龙相形见绌

102
00:10:51,192 --> 00:10:56,030
‎通常来说 这种伪装技术
‎足以保全一只长满了结节的墨鱼

103
00:10:59,950 --> 00:11:01,410
‎但如果其他手段都失效

104
00:11:12,129 --> 00:11:13,130
‎那就放个烟雾弹

105
00:11:21,055 --> 00:11:23,265
‎富含黏液的墨水球

106
00:11:23,349 --> 00:11:26,435
‎模仿出它的形状和大小

107
00:11:29,188 --> 00:11:32,733
‎它抛出诱饵 成功脱身

108
00:11:37,905 --> 00:11:39,323
‎与章鱼不同的是

109
00:11:39,407 --> 00:11:41,534
‎墨鱼体内存在壳体

110
00:11:42,451 --> 00:11:44,286
‎这种内置的浮具

111
00:11:44,370 --> 00:11:46,539
‎让它们成为极其出色的游泳者

112
00:11:47,748 --> 00:11:51,585
‎即便如此
‎经历了如此漫长艰险的旅途后

113
00:11:51,669 --> 00:11:53,504
‎它早已饥肠辘辘

114
00:12:23,951 --> 00:12:24,952
‎变换形状

115
00:12:27,121 --> 00:12:27,955
‎喷出墨水

116
00:12:29,707 --> 00:12:31,584
‎甚至重新长出肢体

117
00:12:33,878 --> 00:12:39,383
‎头足动物的这些超能力
‎让它们能够在危险的水域中存活

118
00:12:50,561 --> 00:12:53,647
‎在加拿大 则是一个

119
00:12:54,231 --> 00:12:56,734
‎克服千难万险 获得成功的故事

120
00:13:05,576 --> 00:13:09,580
‎这只巨型太平洋章鱼如今只有一岁

121
00:13:11,916 --> 00:13:14,585
‎但体型已经是刚出生时的两千倍

122
00:13:16,420 --> 00:13:18,631
‎但成长之路还很漫长

123
00:13:22,843 --> 00:13:26,806
‎三万只章鱼中 只有一只能活到成年

124
00:13:33,771 --> 00:13:35,147
‎为了长大成人

125
00:13:35,773 --> 00:13:39,235
‎它需要依靠自己惊人的视觉

126
00:13:41,612 --> 00:13:42,988
‎一只章鱼眼的视野

127
00:13:43,072 --> 00:13:46,367
‎都比人类两只眼睛加起来的大

128
00:13:49,954 --> 00:13:51,747
‎如果它两只眼睛都用上

129
00:13:56,794 --> 00:13:58,170
‎那便什么都逃不掉它的法眼

130
00:14:00,631 --> 00:14:02,800
‎由于不受坚硬头骨的限制

131
00:14:02,883 --> 00:14:05,511
‎它能独立转动眼球

132
00:14:06,512 --> 00:14:11,809
‎这样便能以几乎360度的广角视野

133
00:14:12,643 --> 00:14:16,355
‎同时看向前后两个方向

134
00:14:21,735 --> 00:14:23,529
‎它因此能寻找食物

135
00:14:25,948 --> 00:14:29,285
‎以及留意危险

136
00:14:33,539 --> 00:14:37,251
‎如同所有的章鱼那样
‎它几乎浑身都是蛋白质

137
00:14:45,259 --> 00:14:46,927
‎所以谁都想咬上一口

138
00:14:55,811 --> 00:14:58,647
‎它现在已经大到能够抵御岩鱼的袭击

139
00:15:00,900 --> 00:15:04,862
‎但总会有更大的掠食者在寻找盘中餐

140
00:15:22,129 --> 00:15:24,381
‎它需要保持警惕

141
00:15:30,220 --> 00:15:32,097
‎没有父母的保护

142
00:15:32,181 --> 00:15:37,019
‎年轻的章鱼必须平衡好
‎它们内在的好奇心与谨慎

143
00:15:41,357 --> 00:15:45,694
‎在变幻莫测的海洋里
‎它们需要有快速学习的能力

144
00:15:46,987 --> 00:15:52,201
‎（巴西 费尔南多迪诺罗尼亚群岛）

145
00:16:00,918 --> 00:16:02,336
‎潮水袭来

146
00:16:03,087 --> 00:16:05,047
‎掠食者鱼贯而入

147
00:16:06,173 --> 00:16:09,093
‎寻找未能逃过退潮的猎物

148
00:16:10,135 --> 00:16:15,099
‎（水深：0至1米
‎水温：26至45摄氏度）

149
00:16:18,602 --> 00:16:20,354
‎被困在一个岩石潮水滩中的

150
00:16:26,026 --> 00:16:29,655
‎是一只九个月大的巴西礁石章鱼

151
00:16:33,575 --> 00:16:35,577
‎被退潮搁浅在海滩

152
00:16:36,537 --> 00:16:38,455
‎它活不了多长时间了

153
00:16:47,464 --> 00:16:51,969
‎但这只足智多谋的小章鱼
‎并不就此认命

154
00:17:08,609 --> 00:17:09,819
‎海面之上

155
00:17:09,903 --> 00:17:11,405
‎这是萨莉轻脚蟹军团

156
00:17:11,488 --> 00:17:15,826
‎期待已久的时刻

157
00:17:17,453 --> 00:17:21,457
‎退潮时期是它们在裸露的岩石上
‎大快朵颐的机会

158
00:17:24,667 --> 00:17:27,921
‎起初 它们貌似坚决不沾水

159
00:17:30,424 --> 00:17:35,262
‎在岩石之间跳出自身身长十倍的距离

160
00:17:42,936 --> 00:17:47,858
‎但如果距离太远
‎它们就不得不纵身入水

161
00:18:08,253 --> 00:18:12,633
‎这可不是凭运气
‎而是周密计划好的伏击

162
00:18:14,384 --> 00:18:18,597
‎小章鱼已经熟悉了螃蟹一贯的
‎高速路线

163
00:18:22,392 --> 00:18:25,270
‎它出色的战略能力

164
00:18:30,859 --> 00:18:34,238
‎源自于它极其罕见的大脑

165
00:18:35,405 --> 00:18:37,366
‎大脑遍布全身

166
00:18:38,158 --> 00:18:42,412
‎三分之二的神经元位于它的肢体里

167
00:18:44,665 --> 00:18:48,252
‎它知道何时按兵不动

168
00:18:49,378 --> 00:18:50,629
‎何时乘胜追击

169
00:19:29,209 --> 00:19:34,798
‎它用隐藏的嘴喙喷发有毒唾液
‎麻痹敌人

170
00:19:36,425 --> 00:19:40,971
‎然后等待唾液中的消化酶
‎腐蚀它的内脏

171
00:19:42,514 --> 00:19:44,224
‎营养丰富的螃蟹奶昔

172
00:19:47,269 --> 00:19:49,980
‎但为了满足成长需要
‎它一天需要吃五只螃蟹

173
00:19:50,564 --> 00:19:53,066
‎所以它在与时间赛跑

174
00:20:06,622 --> 00:20:09,666
‎正午的阳光让潮水滩变小

175
00:20:13,003 --> 00:20:16,423
‎有可能会把它晒成鱼干

176
00:20:22,346 --> 00:20:25,933
‎而且 由于要靠的鳃呼吸

177
00:20:26,683 --> 00:20:28,518
‎很快它就会因为缺水窒息而死

178
00:20:31,939 --> 00:20:34,149
‎还有再过几个小时才涨潮

179
00:20:37,361 --> 00:20:39,613
‎但它想到了一个聪明的办法

180
