1
00:00:03,443 --> 00:00:05,803
波濤洶湧的非洲海角

2
00:00:05,883 --> 00:00:07,443
壯闊的大西洋

3
00:00:07,763 --> 00:00:10,803
將怒火發洩在這裡的岩岸

4
00:00:13,683 --> 00:00:16,883
並為深海的精彩好戲架好舞台

5
00:00:26,643 --> 00:00:29,283
這裡是南非海狗的家

6
00:00:30,403 --> 00:00:33,803
牠們有厚厚的禦寒毛皮保護

7
00:00:34,643 --> 00:00:37,323
在這裡展開了打獵行動

8
00:00:46,963 --> 00:00:51,443
牠們在水中是優雅的流線型特技演員

9
00:00:56,363 --> 00:00:59,083
營養豐富的本格拉洋流

10
00:00:59,163 --> 00:01:01,963
帶來地球上數一數二大的饗宴

11
00:01:03,083 --> 00:01:05,723
小魚像快銀一樣在水中穿梭

12
00:01:05,803 --> 00:01:07,363
海狗也跟上牠們

13
00:01:08,203 --> 00:01:12,403
牠們敏銳的鬍鬚能偵測到魚鰓震動

14
00:01:13,923 --> 00:01:15,483
在開放海域

15
00:01:15,563 --> 00:01:19,243
牠們能以時速30公里在水中前進

16
00:01:24,883 --> 00:01:27,083
這一小群打獵高手

17
00:01:27,163 --> 00:01:31,243
為了覓食每天會游上多達兩百公里

18
00:01:33,403 --> 00:01:35,683
然後再回到南非的海狗島

19
00:01:35,763 --> 00:01:37,603
餵牠們的孩子

20
00:01:38,683 --> 00:01:40,483
但牠們必須先面對

21
00:01:40,563 --> 00:01:42,643
非洲最致命的動物之一

22
00:01:51,243 --> 00:01:54,883
大白鯊是身長六公尺

23
00:01:54,963 --> 00:01:57,963
重達好幾噸的白色死神

24
00:01:58,443 --> 00:02:00,123
而且不只牠一隻

25
00:02:06,803 --> 00:02:09,203
海狗島周圍深深的水道

26
00:02:09,283 --> 00:02:13,763
是全世界大白鯊最密集的地方之一

27
00:02:16,523 --> 00:02:20,283
以古生物來說,牠的構造出奇地複雜

28
00:02:23,523 --> 00:02:25,883
口鼻部有充滿膠狀物的感官

29
00:02:26,003 --> 00:02:29,763
能鎖定來自肌肉動作的電脈衝

30
00:02:32,603 --> 00:02:36,643
特殊的血管能維持牠的核心體溫

31
00:02:37,803 --> 00:02:39,683
以便於在冷水中打獵

32
00:02:45,963 --> 00:02:49,723
海狗有極佳的視力和無比的耐力

33
00:02:49,803 --> 00:02:53,003
但大白鯊有一種致命絕招

34
00:02:53,523 --> 00:02:55,123
牠潛入更深的水中

35
00:02:55,203 --> 00:02:57,283
以神祕的體色當作掩護

36
00:02:58,323 --> 00:03:00,243
在40公里的時速下

37
00:03:00,323 --> 00:03:03,963
用300顆利牙讓海狗一招斃命

38
00:03:14,563 --> 00:03:16,483
有個地方是遠離鯊魚

39
00:03:16,563 --> 00:03:18,243
恐怖統治的庇護天堂

40
00:03:19,883 --> 00:03:21,643
海藻林

41
00:03:26,243 --> 00:03:29,403
大白鯊會避開這些在水中搖擺的葉子

42
00:03:33,403 --> 00:03:36,563
讓這裡成為海狗的寧靜綠洲

43
00:03:39,603 --> 00:03:42,723
也是抵禦海浪的緩衝地帶

44
00:03:46,403 --> 00:03:49,963
快成年的海狗在這裡磨練泳技

45
00:03:50,043 --> 00:03:52,803
尋找藏在巨藻裡的獵物

46
00:03:55,723 --> 00:03:57,923
但牠們不能永遠待在這裡

47
00:04:02,883 --> 00:04:04,603
大白鯊不只有蠻力

48
00:04:04,683 --> 00:04:07,123
還有聰明絕頂的腦袋

49
00:04:07,203 --> 00:04:09,763
能協調牠們敏銳的感官

50
00:04:13,803 --> 00:04:15,683
海狗很聰明

51
00:04:16,563 --> 00:04:19,123
所以鯊魚必須智取牠們

52
00:04:20,123 --> 00:04:21,843
在繁殖季

53
00:04:21,923 --> 00:04:25,323
南非成為大白鯊的世界首都

54
00:04:25,403 --> 00:04:28,483
儘管牠們有著獨行俠的名聲

55
00:04:28,563 --> 00:04:32,123
這些超級掠食者在打獵時會分工合作

56
00:04:36,803 --> 00:04:40,963
大多數海狗都在海藻林裡躲避鯊魚

57
00:04:41,643 --> 00:04:45,563
有一隻落單的海狗暫時放下了戒心

58
00:04:48,003 --> 00:04:50,483
一隻大白鯊引開海狗群的注意

59
00:04:50,563 --> 00:04:52,563
另一隻則去找獵物

60
00:05:17,883 --> 00:05:22,803
寒冷的西海岸上住著另一群刺客

61
00:05:23,523 --> 00:05:24,923
南非鰹鳥

62
00:05:29,363 --> 00:05:30,723
這種大型海鳥

63
00:05:30,803 --> 00:05:35,243
在納米比亞和南非外海的島上繁殖

64
00:05:41,923 --> 00:05:45,083
每年都有成千上萬隻南非鰹鳥

65
00:05:45,163 --> 00:05:47,083
離開牠們在南方的棲地

66
00:05:47,163 --> 00:05:50,683
往東北方飛一千多公里

67
00:06:01,723 --> 00:06:05,483
每年冬天,來自南冰洋的寒冷洋流

68
00:06:05,563 --> 00:06:08,163
會沿著南非的原始海岸往北流

69
00:06:08,243 --> 00:06:10,003
直達莫三比克

70
00:06:13,763 --> 00:06:14,923
隨之而來的是

71
00:06:15,003 --> 00:06:18,243
地球上規模最大的遷徙之一

72
00:06:20,203 --> 00:06:22,003
沙丁魚風暴

73
00:06:25,763 --> 00:06:27,483
在本能的驅使下

74
00:06:27,563 --> 00:06:31,043
幾百萬隻小魚讓海水變得一片黑

75
00:06:31,123 --> 00:06:33,723
並順著較為溫暖的洋流前進

76
00:06:37,363 --> 00:06:39,403
洶湧的非洲洋流

77
00:06:39,523 --> 00:06:42,283
將沿岸的冰涼海水拉近海岸線

78
00:06:42,363 --> 00:06:45,923
掃過熱愛冰水的沙丁魚

79
00:06:57,163 --> 00:07:00,243
牠們繼續前進,用敏銳的視力

80
00:07:00,363 --> 00:07:02,483
尋找可以吃的浮游生物

81
00:07:09,563 --> 00:07:13,363
鰹鳥在來的路上了,但牠們並不孤單

82
00:07:13,803 --> 00:07:17,603
跟在沙丁魚後方的是更致命的軍隊

83
00:07:19,203 --> 00:07:23,443
一群真海豚迅速逼近

84
00:07:28,003 --> 00:07:31,483
牠們以時速30公里在水中快速前進

85
00:07:31,563 --> 00:07:33,563
組成緊密的家庭隊形

86
00:07:36,483 --> 00:07:40,483
想在遼闊的海中找到沙丁魚群不容易

87
00:07:40,563 --> 00:07:43,603
但海豚有一種非常厲害的工具

88
00:07:47,603 --> 00:07:49,003
回聲定位

89
00:07:51,243 --> 00:07:53,003
牠們尖銳的喀答聲

90
00:07:53,083 --> 00:07:55,963
打到物體後會反彈到海豚這邊

91
00:07:56,043 --> 00:08:00,083
告訴牠們該物體的位置,大小和形狀

92
00:08:06,243 --> 00:08:09,283
今天聽起來像是一頓大餐

93
00:08:15,003 --> 00:08:17,843
其他海豚家族也加入戰局

94
00:08:20,563 --> 00:08:25,323
創造出有上千名成員的超級海豚群

95
00:08:38,163 --> 00:08:39,883
牠們包圍魚群

96
00:08:39,963 --> 00:08:43,483
把獵物趕成一個緊密的餌球

97
00:08:47,763 --> 00:08:51,763
一隻隻海豚不斷地輪流從中穿過

98
00:08:51,843 --> 00:08:54,523
大口大口吞下每一隻魚

99
00:08:57,843 --> 00:08:59,603
牠們創造出氣泡網

100
00:08:59,683 --> 00:09:02,323
為了把沙丁魚逼到水面

101
00:09:12,803 --> 00:09:16,123
再對沙丁魚發動空中突襲

102
00:09:22,843 --> 00:09:25,003
魚鰭和魚群翻騰的聲音

103
00:09:25,083 --> 00:09:27,083
讓海水好像沸騰一樣

104
00:09:29,083 --> 00:09:32,483
南非鰹鳥來得正是時候

105
00:09:34,323 --> 00:09:36,683
牠們紛紛俯衝而下

106
00:09:39,523 --> 00:09:41,923
就像一公尺長的導彈

107
00:09:42,003 --> 00:09:45,363
牠們以高達100公里時速衝入水中

108
00:09:45,483 --> 00:09:48,043
下潛將近20公尺深

109
00:09:51,683 --> 00:09:55,563
牠們頭骨周圍的氣囊有助於緩衝

110
00:10:02,283 --> 00:10:04,843
在水中,翅膀和有蹼的腳

111
00:10:04,923 --> 00:10:07,723
讓牠們能追逐速度飛快的魚

112
00:10:11,443 --> 00:10:14,123
牠們可以在水裡待上一分鐘之久

113
00:10:18,963 --> 00:10:21,763
海豚把魚群困在水面

114
00:10:21,843 --> 00:10:25,243
同時鰹鳥從四面八方繼續轟炸

115
00:10:36,003 --> 00:10:39,483
接連幾小時的攻擊摧毀了餌球

116
00:10:57,003 --> 00:11:00,563
海豚繼續追著主要魚群跑的同時

117
00:11:01,403 --> 00:11:05,963
南非鰹鳥則回到棲地餵養雛鳥

118
00:11:07,203 --> 00:11:08,963
對許多小南非鰹鳥來說

119
00:11:09,043 --> 00:11:12,523
這是牠們第一次體驗沙丁魚風暴

120
00:11:27,203 --> 00:11:30,203
對某些鰹鳥來說則是最後一次

121
00:11:30,683 --> 00:11:32,283
在瘋狂的搶食大戰中

122
00:11:32,403 --> 00:11:35,363
南非鰹鳥可能會因為撞擊角度錯誤

123
00:11:35,443 --> 00:11:37,003
而折斷脖子

124
00:11:38,483 --> 00:11:40,683
搶食大戰後的餘波

125
00:11:40,763 --> 00:11:45,643
在水中釋放出誘人的鮮血和魚油味

126
00:11:48,803 --> 00:11:51,803
對鯊魚來說就像是晚餐的鈴聲

127
00:11:55,163 --> 00:11:56,243
鯊魚

128
00:11:57,283 --> 00:11:59,723
是海洋中最古老的掠食者

129
00:11:59,803 --> 00:12:00,803
幾百萬年來

130
00:12:00,883 --> 00:12:03,923
地球的每片海洋都有牠們的身影

131
00:12:06,163 --> 00:12:09,163
具備高度演化的視覺和嗅覺

132
00:12:10,483 --> 00:12:13,083
鯊魚敏銳的感官

133
00:12:13,163 --> 00:12:16,883
和偵測獵物電流的能力

134
00:12:16,963 --> 00:12:19,203
讓牠們成為無所不在的威脅

135
00:12:21,163 --> 00:12:22,963
虎鯊

136
00:12:23,723 --> 00:12:25,723
重達一公噸

137
00:12:25,803 --> 00:12:29,203
是海洋中體型最大的頂級掠食者之一

138
00:12:30,163 --> 00:12:32,483
但牠們並不挑食

139
00:12:32,923 --> 00:12:37,083
不管遇到什麼東西,無論是生是死

140
00:12:37,203 --> 00:12:39,203
牠們都很樂意拿來當晚餐

141
00:12:43,003 --> 00:12:45,923
虎鯊擁有世界上數一數二

142
00:12:46,123 --> 00:12:48,443
能咬碎骨頭的強壯嘴巴

143
00:12:51,443 --> 00:12:55,043
牠們可以迅速吃下死掉或受傷的鰹鳥

144
00:12:55,123 --> 00:12:59,803
再繼續追蹤沙丁魚風暴後留下的浮油

145
00:13:09,163 --> 00:13:13,323
通常在海床附近徘徊的灰真鯊

146
00:13:13,683 --> 00:13:16,643
也會跟著沙丁魚風暴出現

147
00:13:22,603 --> 00:13:25,803
這種技巧高超的重量級殺手

148
00:13:25,883 --> 00:13:29,403
咬力是鯊魚中數一數二強的

149
00:13:32,603 --> 00:13:37,643
灰真鯊大軍再次包圍驅趕沙丁魚群

150
00:13:47,243 --> 00:13:49,123
這些鯊魚一次能吞下

151
00:13:49,203 --> 00:13:52,283
高達自身體重十分之一的食物

152
00:14:08,403 --> 00:14:12,363
牠們一隻接一隻衝入旋轉的餌球中

153
00:14:12,443 --> 00:14:14,083
彷彿那是魚組成的彩罐

154
00:14:14,163 --> 00:14:18,243
牠們張大嘴巴,一口吞掉滿滿的魚

155
00:14:40,723 --> 00:14:44,843
沙丁魚離開後,一切恢復平靜

156
00:14:51,163 --> 00:14:55,243
珊瑚礁乍看之下寧靜又祥和

157
00:14:55,363 --> 00:14:57,723
但這座鮮豔的珊瑚競技場

158
00:14:57,803 --> 00:15:01,243
每天都在上演生存之戰

159
00:15:01,323 --> 00:15:04,403
而礁鯊的表現更是卓越

160
00:15:06,483 --> 00:15:09,723
這些殺手潛入非洲水域時

161
00:15:09,803 --> 00:15:10,963
鮮豔的珊瑚礁

162
00:15:11,043 --> 00:15:13,683
就成了水中版的飢餓遊戲

163
00:15:15,883 --> 00:15:19,163
牠們成群跟蹤躲在珊瑚裡的獵物

164
00:15:20,643 --> 00:15:24,243
既兇狠,暴力又快速

165
00:15:25,203 --> 00:15:29,523
石斑魚大部分時間都待在自己洞穴外

166
00:15:30,483 --> 00:15:33,603
準備在有危險出現時就躲進去

167
00:15:45,443 --> 00:15:49,163
但沒有生物能躲過鯊魚的電磁感應力

168
00:15:55,483 --> 00:15:57,563
餐點端上桌時

169
00:15:57,643 --> 00:15:59,923
角鬥士們就會一決高下

170
00:16:07,723 --> 00:16:12,083
珊瑚礁只占海床不到百分之一的面積

171
00:16:12,163 --> 00:16:15,043
但有超過百分之25的海洋生物

172
00:16:15,123 --> 00:16:16,603
都棲息在珊瑚礁

173
00:16:17,563 --> 00:16:21,203
對於食物和地盤的競爭很激烈

174
00:16:24,123 --> 00:16:27,523
也因此催生出一些奇異的演化結果

175
00:16:31,683 --> 00:16:34,083
這種長相奇特的海底生物

176
00:16:34,163 --> 00:16:36,963
精通突擊的技巧

177
00:16:37,883 --> 00:16:40,123
牠是一隻魴鮄

178
00:16:43,963 --> 00:16:46,643
牠潛伏在沙地和碎屑中

179
00:16:49,563 --> 00:16:52,803
牠斑駁的體色就像海床一樣

180
00:16:53,563 --> 00:16:57,643
獵物接近時幾乎看不見牠的存在

181
00:16:58,043 --> 00:17:02,043
但有時候打獵高手也會變成獵物

182
00:17:06,683 --> 00:17:09,003
另一種會變色的掠食者

183
00:17:09,083 --> 00:17:11,483
擁有卓越的高對比視力

184
00:17:11,563 --> 00:17:14,443
能看穿魴鮄的偽裝

185
00:17:15,923 --> 00:17:17,403
那就是烏賊

186
00:17:17,803 --> 00:17:21,643
擁有超過兩千萬個特殊色素細胞

187
00:17:21,723 --> 00:17:24,883
牠們幾乎能融入任何背景

188
00:17:30,603 --> 00:17:32,803
這還不是牠們唯一的招數

189
00:17:33,603 --> 00:17:36,083
牠們的體腔就像噴射機一樣

190
00:17:36,163 --> 00:17:38,843
讓牠們能像閃電一樣高速前進

191
00:17:43,203 --> 00:17:46,203
牠們是海洋中最聰明的生物之一

192
00:17:46,283 --> 00:17:48,443
狡猾的烏賊會用的招數

193
00:17:48,523 --> 00:17:52,443
包括躲在顯眼的地方突擊獵物

194
00:17:57,443 --> 00:18:01,683
還有迅速變色,以迷惑獵物

195
00:18:07,883 --> 00:18:09,563
但這種變色的招數

196
00:18:09,643 --> 00:18:12,883
對其他也會偽裝的動物來說有用嗎?

197
00:18:21,123 --> 00:18:25,483
魴鮄和許多魚一樣被殺得措手不及

198
00:18:33,763 --> 00:18:38,323
烏賊不是海裡唯一會偽裝的殺手

199
00:18:39,403 --> 00:18:41,843
就在莫三比克外海的溫暖海域

200
00:18:41,923 --> 00:18:45,483
珊瑚礁的數量很多,但危機四伏

201
00:18:47,083 --> 00:18:50,243
這裡是一種冷血殺手的地盤

202
00:18:53,363 --> 00:18:55,923
除了有隱形斗篷之外

203
00:18:56,003 --> 00:18:59,323
石頭魚還會從牠的背鰭棘刺根部

204
00:18:59,403 --> 00:19:01,883
分泌強大的神經毒素

205
00:19:05,003 --> 00:19:07,843
牠是地球上最致命的魚

206
00:19:07,923 --> 00:19:11,763
能在一小時內殺死一個人類

207
00:19:13,603 --> 00:19:16,083
長得像石頭的牠有個缺點

208
00:19:16,163 --> 00:19:18,363
就是牠不擅長游泳

209
00:19:19,883 --> 00:19:22,763
不過話說回來,牠也沒這個必要

210
00:19:23,603 --> 00:19:26,443
牠可以保持靜止不動好幾個小時

211
00:19:26,523 --> 00:19:29,003
直到機會來臨

212
00:20:04,603 --> 00:20:07,603
獵物離牠不到一個身子的距離時

213
00:20:08,883 --> 00:20:11,883
牠會張嘴把獵物吸進去

214
00:20:18,483 --> 00:20:21,003
石頭魚和牠同樣致命的親戚

215
00:20:21,083 --> 00:20:22,443
共享這片珊瑚礁

216
00:20:25,723 --> 00:20:27,603
石狗公

217
00:20:31,363 --> 00:20:35,203
就像石頭魚一樣,牠隱身在珊瑚中

218
00:20:56,203 --> 00:20:59,723
但不同於牠靜止不動的表親

219
00:20:59,803 --> 00:21:03,523
石狗公會悄悄靠近獵物

220
00:21:11,243 --> 00:21:14,483
牠用鰓蓋封住自己的嘴巴

221
00:21:14,923 --> 00:21:18,323
瞬間掀開鰓蓋會產生強大的吸力

222
00:21:18,403 --> 00:21:20,563
帶給獵物死亡之吻

223
00:21:35,763 --> 00:21:40,803
石狗公的超能力是毒液和偽裝能力

224
00:21:41,923 --> 00:21:43,563
章魚更勝一籌

225
00:21:43,643 --> 00:21:47,283
兼具偽裝,用毒,噴射推進的能力

226
00:21:47,363 --> 00:21:50,123
八條超黏的觸手

227
00:21:51,123 --> 00:21:53,963
還有想吃石狗公的渴望

228
00:22:30,803 --> 00:22:35,763
章魚的變色能力能助牠偷偷追蹤獵物

229
00:22:37,563 --> 00:22:39,043
牠還有絕佳的視力

230
00:22:39,123 --> 00:22:43,323
能看穿石狗公出色的偽裝

231
00:22:44,883 --> 00:22:46,483
就算距離很遠也一樣

232
00:22:54,243 --> 00:22:55,323
打獵開始了

233
00:23:01,963 --> 00:23:05,683
章魚的噴射推進力讓牠掌握優勢

234
00:23:14,363 --> 00:23:16,843
但這隻石狗公很幸運

235
00:23:17,203 --> 00:23:19,643
牠找到一個小洞鑽進去

236
00:23:19,723 --> 00:23:22,683
至少今天牠成功死裡逃生了

237
00:23:24,723 --> 00:23:26,963
飢餓的章魚毫不退縮

238
00:23:27,043 --> 00:23:29,483
很快就發現下一個受害者

239
00:23:31,083 --> 00:23:32,483
一隻石頭魚

240
00:23:35,643 --> 00:23:39,043
牠的岩石偽裝騙不了任何生物

241
00:23:39,123 --> 00:23:41,163
尤其是章魚

242
00:23:43,723 --> 00:23:45,523
但章魚還得考慮到牠有毒

243
00:23:45,603 --> 00:23:48,123
牠靈巧地抓住石頭魚

244
00:23:48,203 --> 00:23:50,643
避開有毒的魚鰭

245
00:23:50,723 --> 00:23:53,803
並注入能讓對方癱瘓的毒素

246
00:23:57,763 --> 00:24:01,403
牠退回自己的巢穴享受大餐

247
00:24:05,323 --> 00:24:09,523
在非洲的珊瑚礁,海裡總有更大的魚

248
00:24:10,883 --> 00:24:12,083
而放下戒心

249
00:24:12,163 --> 00:24:14,283
可能會是你生前做的最後一件事

250
00:24:18,523 --> 00:24:20,443
一隻鉸口鯊正在四處覓食

251
00:24:25,483 --> 00:24:27,683
牠是行動緩慢的海底生物

252
00:24:27,763 --> 00:24:30,963
但那正是牠獨特打獵策略的一部分

253
00:24:32,443 --> 00:24:34,043
通常在夜間行動的牠

254
00:24:34,123 --> 00:24:36,883
因為被牠最愛的食物引誘

255
00:24:36,963 --> 00:24:40,043
也就是章魚,忍不住游出巢穴

256
00:24:45,723 --> 00:24:48,243
掠食者對上掠食者

257
00:24:52,803 --> 00:24:54,483
多虧鼻孔前長了

258
00:24:54,563 --> 00:24:57,723
像鬍鬚一樣又高度敏感的觸鬚

259
00:24:57,803 --> 00:25:01,083
沒有任何角落或縫隙能逃出牠的魔掌

260
00:25:06,483 --> 00:25:08,923
章魚迅速逃進洞穴

261
00:25:11,843 --> 00:25:13,443
但還不夠快

262
00:25:19,203 --> 00:25:21,083
鯊魚用窄長的嘴巴

263
00:25:21,163 --> 00:25:23,563
將章魚從藏身處吸出來

264
00:25:24,523 --> 00:25:26,283
章魚的嘴巴雖然有毒

265
00:25:26,363 --> 00:25:28,723
但就像在槍戰中用刀子一樣

266
00:25:28,803 --> 00:25:31,843
完全敵不過咬力驚人的鯊魚

267
00:25:41,443 --> 00:25:43,723
在非洲東南部的沿岸地帶

268
00:25:44,843 --> 00:25:48,723
海洋不斷拍打崎嶇不平的海岸線

269
00:25:52,163 --> 00:25:54,923
海洋和陸地隨著每一陣海浪

270
00:25:55,003 --> 00:25:56,763
上演激烈的交戰

271
00:26:04,523 --> 00:26:06,843
然而,這裡也發展出

272
00:26:06,923 --> 00:26:09,763
最複雜又細膩的生物關係

273
00:26:12,083 --> 00:26:16,243
棕貽貝會過濾潮水帶來的微生物

274
00:26:17,443 --> 00:26:20,723
牠們緊緊將自己黏在礁石上

275
00:26:20,923 --> 00:26:24,043
蠣鴴則試圖把牠們撬下來

276
00:26:30,723 --> 00:26:34,763
如果牠們掉進海裡就會被岩龍蝦搶走

277
00:26:39,203 --> 00:26:40,923
岩龍蝦會用強力的下顎骨

278
00:26:41,003 --> 00:26:42,763
把貽貝像花生一樣壓開

279
00:26:50,123 --> 00:26:51,803
成長快速的青春期龍蝦

280
00:26:51,883 --> 00:26:55,843
每天最多能吃掉體重百分之四的食物

281
00:26:55,923 --> 00:26:57,603
牠們在20年的壽命中

282
00:26:57,683 --> 00:26:59,523
可能永遠不會停止生長

283
00:27:01,003 --> 00:27:04,843
而食物短缺時龍蝦會變得容易生氣

284
00:27:22,363 --> 00:27:25,363
跟冷水域的龍蝦不同

285
00:27:25,443 --> 00:27:29,003
生活在溫暖水域的岩龍蝦沒有大螯

286
00:27:32,363 --> 00:27:37,163
相反地,牠們揮舞著大前角投入戰場

287
00:27:55,123 --> 00:27:57,963
如果威脅沒用,牠們會陷入混戰

288
00:28:00,243 --> 00:28:04,443
最後,最強壯的龍蝦奪走了貽貝

289
00:28:09,523 --> 00:28:12,643
牠用強而有力的口器切斷

290
00:28:12,723 --> 00:28:14,483
封住貽貝的細絲

291
00:28:14,563 --> 00:28:17,323
壓碎貝殼薄薄的邊緣

292
00:28:18,363 --> 00:28:22,083
自私地獨吞這頓美味大餐

293
00:28:24,763 --> 00:28:28,923
在海岸線這邊,競爭一樣激烈

294
00:28:29,323 --> 00:28:33,963
紅潮將岩龍蝦送到幾百隻黑背鷗身邊

295
00:28:35,043 --> 00:28:36,843
隨著更多隻鳥抵達

296
00:28:36,923 --> 00:28:38,443
一場爭鬥正在醞釀

297
00:28:43,483 --> 00:28:44,963
搶食大戰爆發了

298
00:28:45,043 --> 00:28:46,963
黑背鷗爭先恐後地

299
00:28:47,043 --> 00:28:49,323
搶著吃岩龍蝦,螃蟹

300
00:28:49,563 --> 00:28:52,563
以及其他被紅潮沖上岸的東西

301
00:28:56,563 --> 00:29:00,763
這種致命的潮汐發生在強風攪動海水

302
00:29:00,843 --> 00:29:03,443
將藻類從深海翻攪上來的時候

303
00:29:04,603 --> 00:29:06,043
在比較溫暖的水中

304
00:29:06,123 --> 00:29:09,763
藻類會大量生長,吸光水中的氧氣

305
00:29:10,003 --> 00:29:12,363
讓海洋生物窒息

306
00:29:12,443 --> 00:29:15,923
跑來撿食的黑背鷗吃得開心極了

307
00:29:26,483 --> 00:29:29,123
靠著銳利的雙眼和更銳利的嘴巴

308
00:29:29,203 --> 00:29:32,923
牠們發現獵物,並貪婪地一一啄開

309
00:29:43,523 --> 00:29:44,923
如果沒有這些黑背鷗

310
00:29:45,003 --> 00:29:48,723
擱淺的龍蝦會在非洲豔陽下腐爛

311
00:29:51,763 --> 00:29:54,363
所以黑背鷗是在清理海灘

312
00:29:54,443 --> 00:29:56,043
為大眾服務

313
00:30:01,603 --> 00:30:05,243
黑背鷗在空中發出喧鬧的叫聲

314
00:30:05,763 --> 00:30:08,443
而在阿利沃淺灘的珊瑚礁旁

315
00:30:08,603 --> 00:30:10,643
有個打獵高手像死神一樣

316
00:30:10,723 --> 00:30:12,443
無聲無息地潛伏著

317
00:30:17,163 --> 00:30:20,723
以鯊魚來說,牠的動作非常緩慢

318
00:30:21,403 --> 00:30:25,443
但身長3公尺,體重160公斤的牠

319
00:30:25,523 --> 00:30:27,603
卻是不折不扣的鯊魚

320
00:30:28,923 --> 00:30:32,083
錐齒鯊這個名字就說明了一切

321
00:30:32,963 --> 00:30:37,123
牠的牙齒擅長緊咬而非撕裂

322
00:30:38,603 --> 00:30:40,923
牠經常把食物整個吞下肚

323
00:30:51,683 --> 00:30:54,723
牠就跟外表看起來一樣危險

324
00:30:55,323 --> 00:30:59,803
神祕,難以捉摸,兇狠

325
00:31:02,283 --> 00:31:04,403
牠又長又肌肉發達的尾鰭

326
00:31:04,483 --> 00:31:08,123
能以強大的力量瞬間推動牠前進

327
00:31:17,083 --> 00:31:20,283
錐齒鯊整天都在等待時機

328
00:31:21,763 --> 00:31:24,843
在珊瑚礁和沉船附近閒晃

329
00:31:29,163 --> 00:31:32,243
大部分鯊魚必須靠不斷移動才能呼吸

330
00:31:32,323 --> 00:31:36,003
錐齒鯊是唯一能大口吸氣的鯊魚

331
00:31:36,203 --> 00:31:38,083
能讓水流過魚鰓

332
00:31:38,243 --> 00:31:40,123
給了牠們致命的優勢

333
00:31:42,003 --> 00:31:43,363
隱身術

334
00:31:52,803 --> 00:31:55,563
牠們聚集在向北遷徙的路線上

335
00:31:55,843 --> 00:31:58,323
朝莫三比克的溫暖水域前進

336
00:32:03,203 --> 00:32:05,843
牠們在阿利沃淺灘停下來休息

337
00:32:05,923 --> 00:32:08,083
這裡的洞穴能提供遮蔽處

338
00:32:11,563 --> 00:32:13,203
還有充足的獵物

339
00:32:16,763 --> 00:32:21,083
一小群魚游在鯊魚身邊尋求保護

340
00:32:23,643 --> 00:32:26,043
這些鯊魚靠著出奇制勝

341
00:32:26,123 --> 00:32:29,043
捕食任何毫無戒心的受害者

342
00:32:51,403 --> 00:32:53,963
牠往側邊迅速甩一下頭

343
00:32:54,043 --> 00:32:57,523
就立刻將食物一口吞下

344
00:33:27,243 --> 00:33:29,163
就像繁華的城市一樣

345
00:33:29,243 --> 00:33:31,683
非洲致命海洋裡的珊瑚礁

346
00:33:31,763 --> 00:33:33,523
是個充滿驚奇的世界

347
00:33:36,723 --> 00:33:40,763
在五顏六色的構造,溝槽和洞穴中

348
00:33:40,843 --> 00:33:43,723
有上千種魚類興盛繁衍

349
00:33:53,483 --> 00:33:55,323
有一種流線型的掠食者

350
00:33:55,763 --> 00:33:58,483
四處遊走,尋找進食的機會

351
00:33:58,563 --> 00:34:00,483
牠就是鯙鰻

352
00:34:03,923 --> 00:34:06,683
在珊瑚礁穿梭的鯙鰻

353
00:34:06,763 --> 00:34:09,283
會鑽進裂縫深處

354
00:34:09,363 --> 00:34:10,443
想找魚吃

355
00:34:28,443 --> 00:34:33,563
牠有向後彎的尖銳鋸齒和兩組上下顎

356
00:34:33,643 --> 00:34:35,083
沒獵物能逃得過牠

357
00:34:39,563 --> 00:34:44,403
但說到掠食者,這裡不只有鯙鰻

358
00:34:45,643 --> 00:34:51,083
白頂礁鯊和灰礁鯊會獵捕鯙鰻

359
00:35:10,803 --> 00:35:14,243
白頂礁鯊是在海底巡邏

360
00:35:14,323 --> 00:35:17,563
灰礁鯊則在珊瑚礁上方游

361
00:35:18,443 --> 00:35:22,083
讓這條鯙鰻無處可躲

362
00:35:24,003 --> 00:35:26,963
有什麼會比被飢餓的鯊魚追更糟?

363
00:35:27,763 --> 00:35:30,163
就是被一群鯊魚追

364
00:35:55,883 --> 00:35:59,483
這群白頂礁鯊奪走牠們的戰利品

365
00:36:17,883 --> 00:36:21,643
而灰礁鯊只能遠遠地看著

366
00:36:25,123 --> 00:36:29,123
這次牠們只能吃剩菜了

367
00:36:35,483 --> 00:36:39,083
隨著太陽落下,海洋開始躁動

368
00:36:42,403 --> 00:36:46,123
有些大隻南非海狗在沙丁魚風暴後

369
00:36:46,203 --> 00:36:47,963
回到冰冷的水域

370
00:36:48,163 --> 00:36:50,723
不過,這些公海狗即將參與

371
00:36:50,803 --> 00:36:52,523
最後一次打獵行動

372
00:36:55,403 --> 00:36:59,163
帶頭的是海洋中速度最快的掠食者

373
00:37:02,803 --> 00:37:06,923
紅肉旗魚跟任何鯊魚一樣致命

374
00:37:07,003 --> 00:37:09,123
體重超過200公斤

375
00:37:09,203 --> 00:37:12,803
最高時速可達110公里

376
00:37:13,283 --> 00:37:14,603
全副武裝

377
00:37:14,683 --> 00:37:19,563
牠用像劍一樣的嘴巴穿過魚群

378
00:37:19,643 --> 00:37:23,323
再掉頭回來吃被打暈和受傷的受害者

379
00:37:45,883 --> 00:37:49,123
另一名流線型殺手加入打獵行動

380
00:37:49,203 --> 00:37:50,963
讓殺傷力加倍

381
00:37:52,483 --> 00:37:54,563
長著壯觀的背鰭

382
00:37:54,643 --> 00:37:57,843
在近三公尺長的身體上延伸

383
00:37:57,923 --> 00:38:01,403
雨傘旗魚是比紅肉旗魚更快的表親

384
00:38:01,683 --> 00:38:03,963
是海裡速度最快的魚

385
00:38:05,123 --> 00:38:08,963
而且牠不介意為了獵捕而合作

386
00:38:16,123 --> 00:38:18,043
在搶食大戰的過程中

387
00:38:18,123 --> 00:38:20,123
受傷的風險總是很高

388
00:38:24,043 --> 00:38:27,243
尤其牽涉到不只一位掠食者

389
00:38:30,083 --> 00:38:33,683
公海狗試著避開紅肉旗魚的嘴

390
00:38:44,683 --> 00:38:47,763
打獵行動的結束就跟開始一樣突然

391
00:38:53,363 --> 00:38:57,643
今晚,明亮的滿月照耀著大海

392
00:38:57,923 --> 00:39:03,083
夜行性動物紛紛登場,包含白邊真鯊

393
00:39:03,163 --> 00:39:04,403
體型龐大

394
00:39:04,483 --> 00:39:07,803
稱霸一方,性情易怒

395
00:39:10,683 --> 00:39:14,683
白邊真鯊不管對誰都很兇

396
00:39:14,763 --> 00:39:16,723
牠會攻擊同類

397
00:39:16,803 --> 00:39:19,043
就算比自己還大隻

398
00:39:19,603 --> 00:39:21,203
這種可怕的掠食者

399
00:39:21,283 --> 00:39:23,523
有著敏銳的聽覺和嗅覺

400
00:39:26,323 --> 00:39:28,523
以及特別大的眼睛

401
00:39:28,603 --> 00:39:31,203
能看穿黑暗又渾濁的水域

402
00:39:39,283 --> 00:39:41,203
牠又長又寬的口鼻部

403
00:39:41,283 --> 00:39:44,603
藏有幾十排致命的鋸齒狀牙齒

404
00:39:44,723 --> 00:39:47,043
用來鋸穿獵物

405
00:40:12,203 --> 00:40:14,483
牠的皮膚就像盔甲

406
00:40:14,563 --> 00:40:18,123
由堅硬又銳利的皮齒構成

407
00:40:18,203 --> 00:40:19,843
取代了鱗片

408
00:40:23,043 --> 00:40:25,643
白邊真鯊會以突如其來

409
00:40:25,723 --> 00:40:28,003
又無法預測的動作來混淆獵物

410
00:40:30,083 --> 00:40:32,643
牠還能感應到水中的震動

411
00:40:32,723 --> 00:40:35,883
沒有任何獵物或威脅能逃得過牠

412
00:40:38,923 --> 00:40:42,363
魚群形成像甜甜圈的球狀

413
00:40:42,443 --> 00:40:46,443
加上清澈的環流,想躲避攻擊者

414
00:40:49,403 --> 00:40:52,083
但白邊真鯊勢不可擋

415
00:41:14,043 --> 00:41:15,603
在海底

416
00:41:15,683 --> 00:41:19,243
一種和鯊魚是近親的突擊型掠食者

417
00:41:19,323 --> 00:41:21,723
看起來像在水中飛馳一樣

418
00:41:23,603 --> 00:41:26,123
魟魚不是用眼睛

419
00:41:26,203 --> 00:41:29,043
而是用電感覺器官來找食物

420
00:41:30,523 --> 00:41:34,923
牠鋸齒狀尾巴的末梢有致命的毒刺

421
00:41:35,003 --> 00:41:36,723
能嚇阻掠食者

422
00:41:44,883 --> 00:41:46,843
現在有一隻來了

423
00:41:48,923 --> 00:41:54,123
罕見的扁頭哈那鯊慢慢地巡視海底

424
00:42:12,923 --> 00:42:17,363
魟魚急著想躲在海底的沙地裡

425
00:42:19,443 --> 00:42:21,523
但扁頭哈那鯊沒有上當

426
00:42:24,243 --> 00:42:26,483
扁頭哈那鯊出乎意料地敏捷

427
00:42:26,563 --> 00:42:28,563
牠輕鬆就滑過縫隙

428
00:42:44,563 --> 00:42:48,003
牠的感官鎖定潛在獵物時

429
00:42:48,083 --> 00:42:50,163
移動的速度就很快

430
00:43:01,003 --> 00:43:03,163
破壞了魟魚的計畫

431
00:43:03,923 --> 00:43:06,803
現在牠得為了活下去拚命游

432
00:43:14,803 --> 00:43:16,763
但還不夠快

433
00:43:42,203 --> 00:43:45,963
非洲的海洋既遼闊又凶險

434
00:43:46,043 --> 00:43:50,323
雖然充滿生機,卻也步步陷阱

435
00:43:50,603 --> 00:43:53,683
打獵高手和獵物在海中較勁

436
00:43:53,883 --> 00:43:56,323
幾千年來都是這樣

437
00:43:57,443 --> 00:44:01,603
浴血之戰為這個古老生態系帶來平衡

438
00:44:01,683 --> 00:44:04,083
儘管面積如此廣大

439
00:44:04,163 --> 00:44:07,923
獵物無處可逃,也無處可躲

440
00:44:08,003 --> 00:44:10,243
謝謝觀賞
