‎NETFLIX 紀錄片系列

2
00:00:34,576 --> 00:00:38,830
‎牠們是地球上最接近外星人的生物

3
00:00:41,499 --> 00:00:45,837
‎難怪頭足類動物如此引人入勝

4
00:00:51,843 --> 00:00:54,054
‎牠們有外星人般的外表

5
00:00:56,014 --> 00:00:58,600
‎以及驚人的智慧

6
00:00:58,683 --> 00:00:59,934
‎獨立的性格

7
00:01:00,018 --> 00:01:01,895
‎與創新的能力

8
00:01:04,105 --> 00:01:06,941
‎這些罕見的深海傳奇生物

9
00:01:07,025 --> 00:01:10,070
‎還有許多奧秘等待人類發掘

10
00:01:14,532 --> 00:01:18,286
‎比虛幻故事更為離奇的動物

11
00:01:23,583 --> 00:01:28,171
‎劇名：頭足類動物

12
00:01:30,715 --> 00:01:36,012
‎（溫哥華島，加拿大）

13
00:01:41,976 --> 00:01:47,649
‎這片水域養分充足
‎是地球上產量最豐富的海洋之一

14
00:01:51,319 --> 00:01:54,697
‎也是孕育生命絕佳的場所

15
00:01:56,950 --> 00:02:01,746
‎（25公尺深，水溫攝氏5度）

16
00:02:01,830 --> 00:02:03,540
‎潛藏在海浪底下

17
00:02:05,917 --> 00:02:07,252
‎一個神秘的世界

18
00:02:11,798 --> 00:02:14,759
‎十萬顆寶貴的卵

19
00:02:18,763 --> 00:02:22,016
‎每個大小不超過一顆米粒

20
00:02:29,607 --> 00:02:32,986
‎六個月來，牠們受到母親

21
00:02:34,028 --> 00:02:35,029
‎細心的照料

22
00:02:38,700 --> 00:02:41,077
‎這是北太平洋巨型章魚

23
00:02:42,287 --> 00:02:43,288
‎牠的身體

24
00:02:44,164 --> 00:02:45,331
‎是牠們的堡壘

25
00:02:48,209 --> 00:02:50,378
‎母親讓水保持流動

26
00:02:50,461 --> 00:02:53,214
‎以免海藻讓卵窒息

27
00:02:55,842 --> 00:02:57,135
‎每個卵裡

28
00:02:57,844 --> 00:03:02,182
‎都孕育著一個神奇奧妙的生物

29
00:03:04,767 --> 00:03:05,894
‎牠們有八隻手臂

30
00:03:08,313 --> 00:03:09,856
‎三顆心臟

31
00:03:11,232 --> 00:03:12,483
‎與藍色的血液

32
00:03:15,904 --> 00:03:21,034
‎最終，牠們的重量
‎會是現在的25萬倍重

33
00:03:23,077 --> 00:03:26,331
‎成為海洋裡詭計多端的掠食者

34
00:03:29,959 --> 00:03:32,003
‎但只有少數能長大成人

35
00:03:42,222 --> 00:03:45,058
‎該離開安全的保育室了

36
00:04:01,032 --> 00:04:03,785
‎母親最後吐了一口氣

37
00:04:06,204 --> 00:04:09,624
‎這個寶寶便漂進洋流之中

38
00:04:16,589 --> 00:04:18,716
‎就此與母親訣別

39
00:04:27,308 --> 00:04:28,518
‎孤立無援

40
00:04:29,852 --> 00:04:31,729
‎隨波逐流

41
00:04:43,866 --> 00:04:45,410
‎若存活下來

42
00:04:45,493 --> 00:04:46,786
‎牠會在地球上

43
00:04:46,869 --> 00:04:51,833
‎一個不可思議的動物家族裡
‎占有一席之地

44
00:05:03,678 --> 00:05:05,388
‎我們在每個海洋發現…

45
00:05:07,181 --> 00:05:10,435
‎有超過八百種的章魚

46
00:05:12,270 --> 00:05:13,104
‎魷魚

47
00:05:14,272 --> 00:05:15,732
‎以及烏賊

48
00:05:18,318 --> 00:05:19,861
‎牠們是頭足類動物

49
00:05:22,947 --> 00:05:26,284
‎意思就是“頭腳”

50
00:05:27,368 --> 00:05:29,746
‎這要歸因於牠們特殊的解剖結構

51
00:05:30,246 --> 00:05:33,166
‎腕足從臉上長出來

52
00:05:36,627 --> 00:05:39,756
‎但最早的頭足類動物
‎外表比較像這樣

53
00:05:41,883 --> 00:05:43,009
‎這是鸚鵡螺

54
00:05:45,261 --> 00:05:47,638
‎外表類似牠的軟體動物親戚

55
00:05:48,139 --> 00:05:49,140
‎蝸牛

56
00:05:51,726 --> 00:05:55,813
‎五億年來，外表始終如一

57
00:05:59,359 --> 00:06:04,447
‎而其他生物
‎則經過許多令人驚豔的演變

58
00:06:05,448 --> 00:06:07,450
‎牠們卸下身上的殼

59
00:06:08,826 --> 00:06:12,121
‎變得更加靈活敏捷

60
00:06:13,915 --> 00:06:17,835
‎能探索以前無法接觸的地方

61
00:06:21,506 --> 00:06:22,757
‎牠們多變的體型

62
00:06:22,840 --> 00:06:27,095
‎甚至能承受深海巨大的壓力

63
00:06:29,680 --> 00:06:32,058
‎但少了外殼的保護

64
00:06:32,141 --> 00:06:34,268
‎頭足類成了易受攻擊的目標

65
00:06:36,354 --> 00:06:41,025
‎因此牠們發展出近乎超自然的能力

66
00:06:41,109 --> 00:06:42,402
‎來保護自己

67
00:06:48,866 --> 00:06:52,036
‎在滿是掠食者的海洋裡
‎自保非常重要

68
00:06:52,995 --> 00:06:58,084
‎（開普半島，南非）

69
00:07:00,378 --> 00:07:04,340
‎（5公尺深，水溫攝氏15度）

70
00:07:06,509 --> 00:07:09,470
‎海洋可能是個令人生畏的地方

71
00:07:11,848 --> 00:07:14,517
‎如果你的體型只有火柴盒大小

72
00:07:17,937 --> 00:07:20,273
‎保持低調是有好處的

73
00:07:23,067 --> 00:07:26,237
‎但小烏賊不能一輩子躲躲藏藏

74
00:07:31,534 --> 00:07:35,538
‎牠的新陳代謝很快，總是飢腸轆轆的

75
00:07:41,294 --> 00:07:43,754
‎牠最愛吃的生物住在淺水區

76
00:07:45,798 --> 00:07:47,925
‎只在20公尺外

77
00:07:54,265 --> 00:07:58,394
‎但牠的體型很小，這趟旅程可不簡單

78
00:08:02,815 --> 00:08:04,484
‎危機四伏

79
00:08:11,240 --> 00:08:12,783
‎牠很會游泳

80
00:08:14,410 --> 00:08:16,787
‎但魚游得更快

81
00:08:21,375 --> 00:08:23,461
‎視力非常敏銳

82
00:08:25,838 --> 00:08:30,510
‎不過頭足類相當善於融入環境之中

83
00:08:38,518 --> 00:08:40,186
‎精明的烏賊

84
00:08:41,229 --> 00:08:44,065
‎偽裝的功夫更是到家

85
00:08:45,775 --> 00:08:47,777
‎皮膚上特殊的肌肉

86
00:08:48,361 --> 00:08:54,158
‎產生數千個刺狀突起物，稱為結節

87
00:08:56,410 --> 00:08:58,246
‎讓牠看起來像海藻

88
00:09:04,043 --> 00:09:05,711
‎看來奏效了

89
00:09:10,258 --> 00:09:13,386
‎這不是牠唯一的偽裝

90
00:09:16,222 --> 00:09:20,142
‎牠能在瞬間變成各種模樣

91
00:09:27,233 --> 00:09:28,359
‎蝸牛

92
00:09:34,240 --> 00:09:35,074
‎珊瑚

93
00:09:38,869 --> 00:09:39,870
‎或石頭

94
00:09:47,044 --> 00:09:50,506
‎頭足類驚人的變色能力

95
00:09:51,966 --> 00:09:54,343
‎要歸功於色素細胞

96
00:09:56,137 --> 00:10:00,975
‎數百萬個像素狀細胞裡充滿了色素

97
00:10:01,767 --> 00:10:06,105
‎像氣球一樣膨脹收縮

98
00:10:10,943 --> 00:10:14,113
‎快速地變換顏色

99
00:10:21,996 --> 00:10:26,500
‎讓牠們能在瞬間融入背景環境

100
00:10:33,966 --> 00:10:37,094
‎頭足類動物讓變色龍相形失色

101
00:10:38,679 --> 00:10:43,100
‎頭足類的偽裝是動物界中最為精緻的

102
00:10:51,192 --> 00:10:56,030
‎這種偽裝通常足以保護結節烏賊

103
00:10:59,950 --> 00:11:01,410
‎若走投無路

104
00:11:12,129 --> 00:11:13,297
‎就釋放煙霧彈

105
00:11:21,055 --> 00:11:22,848
‎富含黏液的墨珠

106
00:11:23,349 --> 00:11:26,435
‎模擬牠的形狀與大小

107
00:11:29,188 --> 00:11:32,733
‎誘餌布署完畢，牠順勢脫逃

108
00:11:37,905 --> 00:11:39,323
‎不同於章魚

109
00:11:39,407 --> 00:11:41,534
‎烏賊有內殼

110
00:11:42,451 --> 00:11:44,286
‎作為內建的浮力裝置

111
00:11:44,370 --> 00:11:46,622
‎讓牠們成為游泳健將

112
00:11:47,748 --> 00:11:51,585
‎即便如此，經過一段漫長不安的旅程

113
00:11:51,669 --> 00:11:53,504
‎牠也餓了起來

114
00:12:23,951 --> 00:12:24,952
‎變形

115
00:12:27,121 --> 00:12:27,955
‎噴墨

116
00:12:29,707 --> 00:12:31,584
‎甚至重新長出腕足

117
00:12:33,878 --> 00:12:39,383
‎頭足類動物的超能力
‎幫助牠們在險中求生

118
00:12:50,561 --> 00:12:53,647
‎回到加拿大，這是一段排除萬難

119
00:12:54,231 --> 00:12:56,734
‎驚險存活的故事

120
00:13:05,576 --> 00:13:09,580
‎這隻北太平洋巨型章魚現在一歲了

121
00:13:11,916 --> 00:13:14,585
‎體型已經大了兩千倍

122
00:13:16,420 --> 00:13:18,631
‎但成長的路途還很漫長

123
00:13:22,843 --> 00:13:26,806
‎每三萬隻，只有一隻能長大成人

124
00:13:33,771 --> 00:13:35,147
‎為了長大

125
00:13:35,773 --> 00:13:39,235
‎牠必須仰賴絕佳的視力

126
00:13:41,612 --> 00:13:42,988
‎章魚的一隻眼睛

127
00:13:43,072 --> 00:13:46,367
‎視野比人類的兩隻眼睛更遼闊

128
00:13:49,954 --> 00:13:51,747
‎牠使用雙眼時

129
00:13:56,794 --> 00:13:58,629
‎什麼都躲不過牠的法眼

130
00:14:00,631 --> 00:14:02,800
‎牠的眼睛不受頭骨的限制

131
00:14:02,883 --> 00:14:05,511
‎能夠獨立移動

132
00:14:06,512 --> 00:14:11,809
‎因此能同時向前看，向後看

133
00:14:12,643 --> 00:14:16,355
‎幾乎是360度的視野

134
00:14:21,735 --> 00:14:23,529
‎讓牠能掃視食物

135
00:14:25,948 --> 00:14:29,285
‎並且注意危險

136
00:14:33,539 --> 00:14:37,251
‎跟所有章魚一樣
‎牠全身幾乎都是蛋白質

137
00:14:45,259 --> 00:14:46,927
‎所以大家都想吃一口

138
00:14:55,811 --> 00:14:58,647
‎牠現在夠大了，能抵禦岩魚的攻擊

139
00:15:00,900 --> 00:15:04,862
‎但還有更大的掠食者想飽餐一頓

140
00:15:22,129 --> 00:15:24,381
‎牠必須保持警覺

141
00:15:30,220 --> 00:15:32,097
‎沒有父母的保護

142
00:15:32,181 --> 00:15:37,019
‎小章魚好奇地探索世界時
‎必須同時保持謹慎

143
00:15:41,357 --> 00:15:45,694
‎在不斷變化的海洋中
‎小章魚必須快速學習

144
00:15:46,987 --> 00:15:52,201
‎（費爾南多迪諾羅尼亞群島，巴西）

145
00:16:00,918 --> 00:16:02,336
‎潮水漲退時

146
00:16:03,087 --> 00:16:05,047
‎掠食者便會靠近

147
00:16:06,173 --> 00:16:09,093
‎尋找退潮時，滯留在海面的生物

148
00:16:10,135 --> 00:16:15,099
‎（0至1公尺深，水溫攝氏26至45度）

149
00:16:18,602 --> 00:16:20,479
‎困在岩石區潮水潭的…

150
00:16:26,026 --> 00:16:29,655
‎是九個月大的巴西珊瑚章魚

151
00:16:33,575 --> 00:16:35,577
‎與退潮的海洋相隔兩地

152
00:16:36,537 --> 00:16:38,580
‎牠在這裡生存不了多久

153
00:16:47,464 --> 00:16:51,969
‎但這隻足智多謀的小章魚
‎還沒打算放棄

154
00:17:08,609 --> 00:17:09,819
‎在上頭

155
00:17:09,903 --> 00:17:11,696
‎一群紅石蟹

156
00:17:11,780 --> 00:17:15,826
‎一直在等待這個時刻

157
00:17:17,453 --> 00:17:21,457
‎退潮是牠們在裸石上覓食的機會

158
00:17:24,667 --> 00:17:27,921
‎起初，牠們似乎不想弄濕身體

159
00:17:30,424 --> 00:17:35,262
‎牠們在岩石間跳躍
‎距離是身長的十倍

160
00:17:42,936 --> 00:17:47,858
‎若距離太遠，就得冒然跳進海裡

161
00:18:08,253 --> 00:18:12,633
‎這不是幸運，而是精心策劃的埋伏

162
00:18:14,384 --> 00:18:18,597
‎小章魚已經熟悉了螃蟹的習性

163
00:18:22,392 --> 00:18:25,270
‎牠超強的謀略能力…

164
00:18:30,859 --> 00:18:34,238
‎要歸功於極度不尋常的大腦

165
00:18:35,405 --> 00:18:37,366
‎大腦分布在牠的全身

166
00:18:38,158 --> 00:18:42,412
‎三分之二的神經元位於腕足

167
00:18:44,665 --> 00:18:48,252
‎牠無師自通，知道何時該退縮

168
00:18:49,378 --> 00:18:50,629
‎何時該進攻

169
00:19:29,209 --> 00:19:34,798
‎她用隱藏的喙
‎注射有毒的唾液，癱瘓對方

170
00:19:36,425 --> 00:19:40,971
‎等待消化酶液化對方的內部

171
00:19:42,514 --> 00:19:44,558
‎營養的螃蟹奶昔就完成了

172
00:19:47,269 --> 00:19:49,980
‎但牠一天要吃五隻螃蟹
‎才能繼續長大

173
00:19:50,564 --> 00:19:53,066
‎牠分秒必爭地獵食

174
00:20:06,622 --> 00:20:09,666
‎正午的太陽讓潮池的面積逐漸縮小

175
00:20:13,003 --> 00:20:16,423
‎使牠面臨孤立無援的處境

176
00:20:22,346 --> 00:20:25,933
‎牠用溼潤的鰓呼吸時

177
00:20:26,683 --> 00:20:28,518
‎會因缺水窒息而死

178
00:20:31,939 --> 00:20:34,274
‎要好幾個小時，才會再次漲潮

179
00:20:37,361 --> 00:20:39,613
‎但牠想出了一個聰明的辦法

180
00:20:43,909 --> 00:20:48,830
‎牠在頭部後方的洞裡
‎儲存海水，以便呼吸

181

‎多數的頭足類動物
‎只有一次交配的機會

250
