00:00:02,160 --> 00:00:05,240
科德角半島就系
新英格蘭地區嘅夏日樂園

3
00:00:05,240 --> 00:00:06,960
但就喺呢片海岸之外

4
00:00:07,240 --> 00:00:10,680
大白鯊嘅數量越嚟越多

6
00:00:11,000 --> 00:00:13,400
以前所未見嘅方式進行獵食

7
00:00:14,040 --> 00:00:16,920
科德角海岸,疑似發生鯊魚襲擊

8
00:00:17,360 --> 00:00:19,720
一名游泳者腿部被咬傷
已被緊急送往醫院

9
00:00:20,320 --> 00:00:21,600
有咗新科技...

10
00:00:22,920 --> 00:00:24,520
以及驚人嘅發現

11
00:00:24,520 --> 00:00:27,240
呢些動物移動速度之快令人難以置信

12
00:00:27,240 --> 00:00:30,360
科學家哋希望能夠預測鯊魚嘅活動...

13
00:00:30,360 --> 00:00:33,960
我喺距離海岸線
差唔多6米嘅地方標記咗白鯊

14
00:00:33,960 --> 00:00:35,480
嚟保證人哋嘅安全

15
00:00:38,960 --> 00:00:43,320
(大白鯊的奇幻漂流)

16
00:00:44,920 --> 00:00:47,160
喺美國嘅東北角

17
00:00:47,160 --> 00:00:48,080
(波士頓)
(馬薩諸塞州)

18
00:00:48,080 --> 00:00:51,680
從科德角到馬薩諸塞州海岸

19
00:00:51,680 --> 00:00:53,320
遍布著海灘小鎮

20
00:00:55,280 --> 00:00:58,320
夏天系游客嘅高峰期

21
00:00:59,880 --> 00:01:01,040
鯊魚也一樣

22
00:01:03,440 --> 00:01:06,120
大白鯊會喺夏天遷徙到啵度

23
00:01:06,520 --> 00:01:09,200
捕食數量唔斷增加嘅海豹

24
00:01:11,360 --> 00:01:13,960
呢一切就發生喺城鎮和海灘旁

25
00:01:15,440 --> 00:01:17,960
十年內有過五次襲擊人類事件

26
00:01:18,320 --> 00:01:22,960
其中一次致人死亡
所以知曉安全下水時間很重要

27
00:01:22,960 --> 00:01:23,920
(警告)

28
00:01:23,920 --> 00:01:26,720
白鯊喺大量回歸

29
00:01:27,200 --> 00:01:29,520
海豹種群也一直喺恢複中

30
00:01:30,840 --> 00:01:32,280
但存喺一個問題

31
00:01:32,800 --> 00:01:35,760
人類活動與佢哋存喺交集

32
00:01:37,520 --> 00:01:38,400
作為一個父親

33
00:01:38,400 --> 00:01:41,600
我很難睇著我嘅囡囡走入海水中

34
00:01:42,160 --> 00:01:43,800
因為真嘅很可能

35
00:01:43,800 --> 00:01:46,480
喺佢游泳嘅地方就有一只白鯊

36
00:01:47,880 --> 00:01:49,880
為咗減少鯊魚傷人事件嘅幾率

37
00:01:51,520 --> 00:01:53,920
科學家格雷格斯科馬和梅根溫頓

38
00:01:54,560 --> 00:01:57,120
與大西洋白鯊保護協會合作

39
00:01:57,560 --> 00:02:00,560
希望能夠更成功地預測鯊魚活動

40
00:02:06,800 --> 00:02:08,920
我哋希望能夠更掂地為

41
00:02:09,360 --> 00:02:11,680
{\an8}公共安全官員、海灘游客

42
00:02:11,680 --> 00:02:12,640
{\an8}(格雷格斯科馬博士)
(魚類生物學家)

43
00:02:12,640 --> 00:02:16,560
{\an8}和公眾提供建議
告訴佢哋鯊魚最有可能出現喺邊度

44
00:02:16,560 --> 00:02:18,920
以及佢哋可能喺何時何地捕食海豹

45
00:02:21,720 --> 00:02:25,560
為咗確定鯊魚可能喺邊度
以及何時出現嘅幾率

46
00:02:25,880 --> 00:02:30,680
佢哋喺科德角周圍
標記、跟蹤和拍攝白鯊

47
00:02:32,080 --> 00:02:34,440
自2014年以嚟我哋一直喺努力

48
00:02:34,440 --> 00:02:36,240
{\an8}回答嘅一大問題系...

49
00:02:36,240 --> 00:02:37,200
{\an8}(梅根溫頓)
(研究科學家)

50
00:02:37,200 --> 00:02:39,120
{\an8}每年有幾多條大白鯊嚟到啵度

51
00:02:39,640 --> 00:02:44,240
如果佢哋能估計出科德角白鯊嘅總數

52
00:02:44,680 --> 00:02:46,840
呢就會系成功嘅第一步

53
00:02:47,760 --> 00:02:51,320
我哋每次出海都仲會見到新嘅鯊魚

54
00:02:52,560 --> 00:02:54,960
格雷格和梅根也惗要咗解

55
00:02:54,960 --> 00:02:59,960
鯊魚如何利用啵度
獨特嘅水下地形捕食海豹

56
00:03:00,240 --> 00:03:03,920
其中包括發動襲擊前嘅最後時刻

57
00:03:06,240 --> 00:03:08,440
但首先,佢哋必須得搵到一條鯊魚

58
00:03:10,600 --> 00:03:12,040
喺兩點鐘方向

59
00:03:12,040 --> 00:03:13,520
掂嘅,知道咗

60
00:03:13,520 --> 00:03:16,400
偵察飛行員能夠相對容易地搵到佢哋

61
00:03:16,400 --> 00:03:18,360
現喺系一點鐘方向

62
00:03:18,840 --> 00:03:21,520
海底系美麗嘅白色沙灘

63
00:03:21,520 --> 00:03:25,400
與海水中深灰色動物形成咗鮮明對比

64
00:03:25,840 --> 00:03:26,960
現喺就喺我嘅下方

65
00:03:27,520 --> 00:03:30,600
維恩指引著研究船駛向嗰條鯊魚

66
00:03:31,560 --> 00:03:32,760
現喺距離幾百米

67
00:03:33,240 --> 00:03:35,240
我哋只系喺偷偷接近佢

68
00:03:35,240 --> 00:03:36,200
就喺嗰度!

69
00:03:36,200 --> 00:03:40,000
然後我哋用運動相機拍下咗水下視頻

70
00:03:40,440 --> 00:03:42,040
睇嘞,睇睇佢!

71
00:03:42,400 --> 00:03:43,840
喺評估我哋!

72
00:03:44,680 --> 00:03:48,200
如果佢喺合適深度嘅水里徘徊
佢就能俾佢做上標記

73
00:03:48,200 --> 00:03:49,280
嚟吧,親愛嘅!

74
00:03:52,840 --> 00:03:53,760
真唔錯

75
00:03:54,480 --> 00:03:55,880
完美極咗

76
00:03:56,320 --> 00:03:59,880
喺每次標記中
我哋也收集著各種各樣嘅信息

77
00:04:00,400 --> 00:04:02,920
喺哪兒睇到嘅鯊魚,水溫系幾多

78
00:04:02,920 --> 00:04:05,000
水深系幾多

79
00:04:05,000 --> 00:04:06,960
鯊魚本身有多大

80
00:04:07,360 --> 00:04:10,240
我哋會喺呢一天中重複咁樣做

81
00:04:11,880 --> 00:04:14,360
佢哋拍攝著唔同樣子

82
00:04:14,360 --> 00:04:15,520
唔同大小

83
00:04:15,520 --> 00:04:17,440
和唔同性格嘅鯊魚

84
00:04:18,920 --> 00:04:20,080
佢直奔鏡頭過嚟咗!

85
00:04:23,280 --> 00:04:25,080
佢制定系被激怒咗

86
00:04:25,400 --> 00:04:27,520
呢些小家夥往往很掂鬥

87
00:04:28,480 --> 00:04:30,840
現喺佢又往船呢邊過嚟咗
睇睇佢要做乜嘢!

88
00:04:32,800 --> 00:04:35,720
身上有很多海豹造成嘅劃痕
嗰系努力捕食嘅證明!

89
00:04:36,280 --> 00:04:41,280
像咁樣年輕嘅小鯊魚
可能系缺乏經驗嘅獵手

90
00:04:42,400 --> 00:04:45,560
也許佢哋仲唔擅長捕獵
佢哋正喺磨練自己嘅技能

91
00:04:47,600 --> 00:04:48,960
海豹系大型動物

92
00:04:49,560 --> 00:04:53,080
佢哋本身就系很有能力嘅捕食者

93
00:04:53,080 --> 00:04:55,240
佢哋有尖牙利爪

94
00:04:55,240 --> 00:04:59,400
因此如果鯊魚唔能成功地一擊致命

95
00:04:59,400 --> 00:05:00,840
海豹就會反擊

96
00:05:01,680 --> 00:05:02,800
我哋將之稱作海豹紋

97
00:05:02,800 --> 00:05:05,040
鯊魚嘅身上都會有海豹抓撓嘅痕跡

98
00:05:05,840 --> 00:05:07,680
所以其中一些個體

99
00:05:07,680 --> 00:05:09,960
尤其系體型較小嘅個體

100
00:05:09,960 --> 00:05:11,680
可能仲唔懂

101
00:05:12,040 --> 00:05:14,120
如何最掂地獵食一只海豹

102
00:05:14,360 --> 00:05:18,080
就會喺佢哋身上睇到大量海豹劃痕

103
00:05:19,400 --> 00:05:22,960
每個標記都會幫助記錄和跟蹤鯊魚

104
00:05:26,000 --> 00:05:26,840
中咗!

105
00:05:27,440 --> 00:05:28,680
仲唔錯!

106
00:05:30,400 --> 00:05:31,360
睇嘞!

107
00:05:33,800 --> 00:05:34,840
就喺後面!

108
00:05:38,800 --> 00:05:39,960
佢撞咗我哋!

109
00:05:41,160 --> 00:05:42,120
佢唔鍾意我哋

110
00:05:43,280 --> 00:05:46,280
你知道嘎,我都快被嗰家夥撞暈咗!

111
00:05:48,120 --> 00:05:50,600
我以為佢只系要離開近海

112
00:05:50,600 --> 00:05:51,800
因為佢喺開始加速

113
00:05:51,800 --> 00:05:53,400
結果佢突然轉咗方向

114
00:05:54,560 --> 00:05:55,880
撞上咗船!

115
00:05:57,080 --> 00:05:59,360
睇到嗰條鯊魚發嬲時,我哋就知道會咁樣

116
00:05:59,360 --> 00:06:01,720
我惗呢條鯊魚處喺高強度嘅進食狀態

117
00:06:01,720 --> 00:06:05,720
而呢種狀態嘅鯊魚正系我哋憂心嘅

118
00:06:06,480 --> 00:06:09,040
對喺啵度標浪潛水及游泳嘅人
嚟話系一種危險

119
00:06:10,800 --> 00:06:11,760
難以置信

120
00:06:14,520 --> 00:06:18,840
佢哋嘅研究表明鯊魚數量正喺增加

121
00:06:20,320 --> 00:06:22,800
但到底有幾多鯊魚啵?

122
00:06:22,800 --> 00:06:24,080
自2014年以嚟

123
00:06:24,080 --> 00:06:27,600
我哋一直進行著密集嘅種群研究

124
00:06:27,600 --> 00:06:29,320
每周出海兩次

125
00:06:29,320 --> 00:06:31,040
拍攝水下視頻

126
00:06:31,040 --> 00:06:34,520
基本建立咗一個科德角白鯊目錄

127
00:06:35,520 --> 00:06:38,920
我哋現喺要做嘅
就系利用呢些信息進行推斷

128
00:06:38,920 --> 00:06:40,880
得出白鯊嘅大致總數量

129
00:06:43,160 --> 00:06:44,920
佢哋已經記錄咗數百條鯊魚

130
00:06:45,480 --> 00:06:49,280
但佢哋相信仲有幾百條未被記錄

131
00:06:51,440 --> 00:06:53,600
如果你喺25年前對我話

132
00:06:54,280 --> 00:06:57,440
周圍會有很多食海豹嘅白鯊

133
00:06:57,440 --> 00:07:00,760
而你要去標記佢哋,我會話你瘋咗

134
00:07:01,920 --> 00:07:06,320
但喺過去10年里

135
00:07:06,960 --> 00:07:08,320
我哋標記咗250多條鯊魚

136
00:07:08,920 --> 00:07:10,480
呢系我從沒惗象過嘅事情

137
00:07:10,840 --> 00:07:14,320
但呢系一個自然生態系統嘅恢複

138
00:07:16,120 --> 00:07:17,000
原因系乜嘢?

139
00:07:17,640 --> 00:07:18,560
海豹哋

140
00:07:19,360 --> 00:07:21,040
喺20世紀70年代之前

141
00:07:21,360 --> 00:07:23,920
漁民哋視海豹為競爭對手

142
00:07:24,240 --> 00:07:25,680
一見就殺

143
00:07:27,240 --> 00:07:29,440
佢哋嘅數量大量減少

144
00:07:29,800 --> 00:07:31,920
冇咗穩定嘅食物嚟源

145
00:07:32,800 --> 00:07:33,960
鯊魚選擇離開啵度

146
00:07:35,040 --> 00:07:37,760
幾代人以嚟,海豹越嚟越少

147
00:07:37,760 --> 00:07:40,280
大白鯊更系極其稀少

148
00:07:41,160 --> 00:07:42,720
但喺1972年

149
00:07:42,720 --> 00:07:45,520
根據《海洋哺乳動物保護法》

150
00:07:45,520 --> 00:07:47,840
海豹被宣布為受保護物種

151
00:07:48,960 --> 00:07:52,560
據估計現喺科德角地區

152
00:07:52,560 --> 00:07:54,120
有多達五萬只海豹

153
00:07:55,520 --> 00:07:57,200
佢哋嘅數量已經回升

154
00:07:58,440 --> 00:08:00,320
鯊魚也一樣

155
00:08:02,200 --> 00:08:05,560
有咗咁樣一個驚人嘅自然生態系統

156
00:08:05,560 --> 00:08:09,400
有捕食者大白鯊,仲有獵物海豹

157
00:08:10,520 --> 00:08:12,560
然後仲有人嚟到啵度

158
00:08:12,560 --> 00:08:14,920
與呢對捕食者和獵物產生交集

159
00:08:15,760 --> 00:08:21,120
我哋意識到考慮公共安全嘅重要性

160
00:08:22,560 --> 00:08:24,760
所以喺過去幾年里

161
00:08:24,760 --> 00:08:26,960
我哋開始深入研究

162
00:08:26,960 --> 00:08:30,400
白鯊嘅捕食行為

163
00:08:33,720 --> 00:08:37,080
世界各地嘅大白鯊都系伏擊獵手

164
00:08:38,360 --> 00:08:42,560
佢哋會以強大嘅爆發力
突然從深水標向水面

165
00:08:45,640 --> 00:08:47,720
但呢喺科德角行唔通

166
00:08:49,120 --> 00:08:53,040
啵度嘅海灘被淺淺嘅沙洲所環繞

167
00:08:54,680 --> 00:08:56,560
冇咗水深優勢

168
00:08:56,880 --> 00:09:00,120
鯊魚就很難伏擊海豹

169
00:09:00,600 --> 00:09:02,560
所以佢哋必須更聰明地捕食

170
00:09:04,600 --> 00:09:08,320
格雷格和梅根嘅任務
就系揭秘佢哋嘅捕食方式

171
00:09:09,320 --> 00:09:12,480
白鯊嘅捕食策略就系潛行

172
00:09:17,440 --> 00:09:19,720
海豹緊緊地貼喺沙灘上

173
00:09:21,200 --> 00:09:24,000
佢哋知道只要水位足夠淺
鯊魚就沒辦法靠近

174
00:09:25,680 --> 00:09:28,240
所以我哋睇到嘅系鯊魚

175
00:09:28,240 --> 00:09:29,600
喺淺水區撩戰自己

176
00:09:30,920 --> 00:09:32,880
如果你喺海岸線外觀察佢哋

177
00:09:33,440 --> 00:09:35,440
佢哋就像系喺巡航

178
00:09:35,440 --> 00:09:37,840
等待著犯錯嘅海豹

179
00:09:41,080 --> 00:09:43,560
喺海灘上冇危險

180
00:09:44,360 --> 00:09:46,080
但系海豹要食魚

181
00:09:46,400 --> 00:09:49,000
所以佢哋必須離開安全嘅海灘

182
00:09:53,440 --> 00:09:54,800
對鯊魚哋嚟話

183
00:09:54,800 --> 00:09:59,480
每只下水嘅海豹都有可能
成為一頓高熱量嘅大餐

184
00:10:00,960 --> 00:10:02,000
為咗生存

185
00:10:02,240 --> 00:10:06,640
大白鯊每周必須食掉
相當於18千克鯨脂嘅食物

186
00:10:07,240 --> 00:10:09,680
為此佢哋會唔惜任何代價

187
00:10:14,200 --> 00:10:16,000
喺呢片淺水里

188
00:10:16,000 --> 00:10:18,680
一條乸鯊魚殺死咗一只海豹

189
00:10:19,720 --> 00:10:21,960
但呢場戰鬥才剛過半

190
00:10:23,560 --> 00:10:26,600
海浪將海豹屍體推向拍岸浪區

191
00:10:27,600 --> 00:10:28,920
使其無法觸及

192
00:10:30,040 --> 00:10:32,560
但系呢條乸鯊魚冇離去

193
00:10:35,680 --> 00:10:40,680
佢盡力喺只有幾十厘米嘅
淺水區接近海豹屍體!

194
00:10:41,720 --> 00:10:43,320
如果無法夠到佢

195
00:10:43,320 --> 00:10:45,320
佢就系嘥咗寶貴嘅能量

196
00:10:46,760 --> 00:10:48,160
佢喺淺水里

197
00:10:49,160 --> 00:10:53,320
你可以睇到佢嘅孭鰭露出咗水面

198
00:10:54,040 --> 00:10:55,600
但距離仲系太遠咗

199
00:10:59,120 --> 00:11:03,520
海豹流出嘅血吸引咗
更多鯊魚嚟到呢片海域

200
00:11:04,960 --> 00:11:08,160
呢條乸鯊魚嘅機會渺茫

201
00:11:09,240 --> 00:11:13,280
一頓富含脂肪和蛋白質嘅大餐

202
00:11:13,280 --> 00:11:15,720
會讓付出和冒險變得抵

203
00:11:20,960 --> 00:11:23,280
海豹系白鯊嘅大餐

204
00:11:26,480 --> 00:11:28,120
海豹唔系佢哋唯一嘅食物

205
00:11:28,800 --> 00:11:31,160
但就能量而言,食一只海豹

206
00:11:31,160 --> 00:11:34,240
就相當於食咗成百上千條魚

207
00:11:35,440 --> 00:11:37,640
但系捕食海豹並唔簡單

208
00:11:38,400 --> 00:11:42,120
鯊魚嘅嘗試十有八九會失敗

209
00:11:53,480 --> 00:11:55,160
唔管成功與否

210
00:11:55,520 --> 00:11:57,400
掠食性鯊魚回到呢個旅游聖地

211
00:11:57,680 --> 00:12:01,120
會對人哋造成威脅

212
00:12:04,400 --> 00:12:08,480
格雷格和梅根惗要
更掂地咗解鯊魚嘅行為

213
00:12:09,600 --> 00:12:11,160
我哋惗要咗解佢哋嘅習性

214
00:12:11,160 --> 00:12:13,680
咗解佢哋如何決定喺何時何地

215
00:12:13,680 --> 00:12:16,360
對海豹發起獵殺

216
00:12:16,720 --> 00:12:20,800
但系極難目睹鯊魚發動攻擊嘅瞬間

217
00:12:21,480 --> 00:12:23,960
將之拍攝下嚟就更為難得

218
00:12:25,160 --> 00:12:27,800
所以佢哋幫助開發咗

219
00:12:28,120 --> 00:12:30,760
喺科德角從未使用過嘅新攝像技術

220
00:12:32,120 --> 00:12:33,440
第一次

221
00:12:33,440 --> 00:12:37,760
呢些信標將會從內部記錄下

222
00:12:38,160 --> 00:12:40,280
大白鯊嘅獨特行為

223
00:12:42,440 --> 00:12:44,240
佢里面嵌入咗一個相機系統

224
00:12:44,520 --> 00:12:48,640
所以佢可以記錄下鯊魚嘅一舉一動

225
00:12:48,640 --> 00:12:53,480
呢幾天觀察者會像系騎喺鯊魚孭上

226
00:12:53,480 --> 00:12:55,560
嚟觀察佢嘅行為

227
00:12:56,080 --> 00:12:57,760
鯊魚會表現出唔同嘅行為

228
00:12:57,760 --> 00:12:59,680
而我哋會記錄下呢些行為

229
00:13:00,160 --> 00:13:03,040
唔系每隔一小時,也唔系每隔一分鐘
而系每秒無間斷嘅記錄

230
00:13:06,440 --> 00:13:07,880
喺兩點鐘方向,約翰

231
00:13:08,640 --> 00:13:09,600
有點深

232
00:13:09,960 --> 00:13:12,040
呢信標上有個終端

233
00:13:12,040 --> 00:13:15,840
跟大家手機里跟蹤日常活動嘅一樣

234
00:13:16,200 --> 00:13:18,400
佢有一個三維加速度計

235
00:13:18,400 --> 00:13:21,920
每秒記錄20次

236
00:13:22,560 --> 00:13:25,400
記錄下動物嘅運動和行為

237
00:13:26,800 --> 00:13:29,360
-真靚
-佢嘅體型很靚

238
00:13:29,720 --> 00:13:30,920
我沒睇到標記

239
00:13:32,480 --> 00:13:33,480
系美懶懶!

240
00:13:34,360 --> 00:13:37,400
一條3.7米長嘅大白鯊

241
00:13:38,800 --> 00:13:43,360
人哋可能會認為
俾大白鯊取綽號唔太嚴謹

242
00:13:43,960 --> 00:13:47,400
但佢哋能幫助我哋記住呢些鯊魚

243
00:13:47,800 --> 00:13:49,640
睇到佢我哋就知道系美懶懶

244
00:13:50,360 --> 00:13:52,840
仲有很多人覺得鯊魚長得都一樣

245
00:13:52,840 --> 00:13:56,280
但其實每條鯊魚都有著唔同嘅特徵

246
00:13:56,280 --> 00:13:59,240
和色彩紋理

247
00:13:59,240 --> 00:14:02,120
我哋就能通過外表分辨佢哋

248
00:14:03,800 --> 00:14:05,880
有點難度,準備掂翻嘎?

249
00:14:06,480 --> 00:14:07,320
掂翻!

250
00:14:07,840 --> 00:14:09,200
準備掂開始吧

251
00:14:10,000 --> 00:14:12,000
佢往左邊游咗一點,約翰

252
00:14:12,000 --> 00:14:14,880
信標必須被完美地安置到美懶懶身上

253
00:14:14,880 --> 00:14:18,000
咁樣相機才能捕捉佢嘅每個動作

254
00:14:18,000 --> 00:14:18,960
慢點

255
00:14:22,360 --> 00:14:24,720
佢鍾意到水面上嚟
我哋就喺下一次時搞定吧

256
00:14:26,120 --> 00:14:27,960
我哋有時會睇到佢哋咁樣

257
00:14:27,960 --> 00:14:29,400
喺標記過程中我哋發現

258
00:14:29,400 --> 00:14:33,920
佢哋鍾意像咁樣上下游動

259
00:14:36,120 --> 00:14:39,200
但呢條鯊魚需要嗱嗱啉上嚟
接收佢嘅信標!

260
00:14:39,960 --> 00:14:42,240
拜托,快上嚟吧

261
00:14:49,840 --> 00:14:53,040
靚,真系太叻咗!

262
00:14:53,040 --> 00:14:54,840
-太掂翻!
-掂耶!

263
00:14:56,240 --> 00:14:58,160
現喺要做嘅就系等待咗

264
00:14:58,160 --> 00:15:01,240
睇睇美懶懶接下嚟要做乜嘢

265
00:15:01,240 --> 00:15:02,160
佢喺嗰度!

266
00:15:03,480 --> 00:15:05,120
佢就喺嗰兒!

267
00:15:05,920 --> 00:15:07,760
嗰家夥嘅狩獵地離我哋很近

268
00:15:08,400 --> 00:15:11,880
現喺被標記咗嘅鯊魚

269
00:15:12,320 --> 00:15:17,240
美懶懶就喺靠近海灘嘅海豹旁邊

270
00:15:17,240 --> 00:15:19,120
呢正系我哋惗要嘅

271
00:15:19,120 --> 00:15:20,080
沒錯

272
00:15:20,080 --> 00:15:23,480
所以呢項研究就系要描述鯊魚嘅行為

273
00:15:23,480 --> 00:15:26,560
並增進更多關於佢哋喺呢片海灘

274
00:15:26,560 --> 00:15:28,520
附近水域獵食海豹嘅咗解

275
00:15:31,360 --> 00:15:35,720
我哋惗要弄清楚白鯊喺何時、何地

276
00:15:35,720 --> 00:15:37,200
以及如何捕食佢哋嘅獵物海豹

277
00:15:37,960 --> 00:15:40,000
如果我哋能搵到鯊魚嘅行為糢式

278
00:15:40,000 --> 00:15:42,560
嗰麼我哋就可以預測佢哋

279
00:15:42,920 --> 00:15:44,840
可能嘅進食點與人類活動地

280
00:15:45,200 --> 00:15:48,640
之間產生交集嘅地方

281
00:15:49,200 --> 00:15:50,920
呢就系讓我哋做到呢一點嘅工具

282
00:15:55,320 --> 00:16:00,000
鯊魚身上嘅信標仲要等幾天才會除落

283
00:16:01,760 --> 00:16:05,320
如果格雷格和梅根
能追蹤到信標嘅無線電信號

284
00:16:05,760 --> 00:16:08,120
佢哋就能收回有價值嘅數據

285
00:16:09,120 --> 00:16:12,720
可能仲有發起捕食嘅詳細錄像

286
00:16:15,960 --> 00:16:17,080
掂翻,呢個已經搞定咗

287
00:16:18,120 --> 00:16:19,920
掂嘅,現喺系一點鐘方向

288
00:16:20,680 --> 00:16:22,240
系漲潮

289
00:16:22,240 --> 00:16:25,360
仲系退潮、白天或者晚上

290
00:16:26,040 --> 00:16:28,720
我哋喺使用各種工具嚟更掂地咗解

291
00:16:28,720 --> 00:16:32,680
鯊魚行為受到乜嘢環境因素影嚮

292
00:16:37,040 --> 00:16:38,880
我現喺要返航咗

293
00:16:39,200 --> 00:16:42,480
最易發現鯊魚嘅角度就系從空中俯瞰

294
00:16:43,280 --> 00:16:45,760
就我個人嚟話,我睇到嘅鯊魚數量

295
00:16:45,760 --> 00:16:46,680
{\an8}(維恩戴維斯)
(飛行員)

296
00:16:46,680 --> 00:16:49,960
{\an8}遠遠超過常人,多嘅多得多

297
00:16:49,960 --> 00:16:53,640
{\an8}因為你知道大白鯊嘅標準形象

298
00:16:53,640 --> 00:16:55,600
系孭鰭露出水面游動嘅樣子

299
00:16:55,600 --> 00:16:58,640
就像電影《大白鯊》里嗰樣
但系嗰基本唔現實

300
00:16:59,040 --> 00:17:01,520
佢哋都會喺水下游動
所以才有咗我嘅工作

301
00:17:01,520 --> 00:17:05,000
唯一能搵到鯊魚嘅辦法就系借助飛機

302
00:17:06,240 --> 00:17:10,560
我見過幾次白鯊獵食海豹

303
00:17:11,200 --> 00:17:15,960
但大多數時候,海豹哋都非常敏銳和敏捷

304
00:17:18,360 --> 00:17:21,400
就像呢只海豹迅速跳到一邊

305
00:17:22,000 --> 00:17:24,680
搞掂咗180度或者270度轉彎

306
00:17:25,440 --> 00:17:29,720
佢繞到鯊魚身後尾巴嗰邊
嗰度系安全地帶

307
00:17:32,680 --> 00:17:34,440
即使系鳥瞰嘅視角

308
00:17:34,440 --> 00:17:38,240
維恩喺一年中也
只睇到過幾次未遂嘅捕食行為

309
00:17:42,360 --> 00:17:44,840
但佢睇到嘅唔只呢些

310
00:17:46,640 --> 00:17:48,440
海灘上嘅人唔知道佢哋就喺嗰度

311
00:17:51,440 --> 00:17:55,160
就喺游泳者、標浪者哋嘅右方

312
00:17:57,240 --> 00:17:59,760
與人嘅危險互動非常罕見

313
00:18:00,480 --> 00:18:03,200
但你必須保持警惕

314
00:18:05,920 --> 00:18:08,960
旅游業系科德角地區嘅經濟支柱

315
00:18:10,080 --> 00:18:13,440
夏天啵度嘅人啖會增加一倍多

316
00:18:14,080 --> 00:18:16,600
海灘游客嘅數量也會增加一倍多

317
00:18:19,160 --> 00:18:23,160
夏天也系鯊魚嘅黃金時間

318
00:18:28,160 --> 00:18:29,480
喺過去十年中

319
00:18:29,800 --> 00:18:33,040
科德角發生過五起鯊魚襲擊人類事件

320
00:18:33,440 --> 00:18:36,200
最近一次發生喺2018年
並且導致咗人員死亡

321
00:18:36,200 --> 00:18:39,200
{\an8}受害者被緊急送往醫院
並喺嗰度被宣布死亡

322
00:18:40,520 --> 00:18:42,640
但絕大多數海灘游客

323
00:18:42,640 --> 00:18:44,560
無論系游客仲系本地人

324
00:18:44,560 --> 00:18:46,960
並冇改變佢哋嘅游泳習慣

325
00:18:49,200 --> 00:18:52,040
本地人憂心對旅游業嘅影嚮

326
00:18:52,040 --> 00:18:57,600
但就像大白鯊一樣,游客嘅數量也喺增加

327
00:18:59,480 --> 00:19:03,800
如此靠近海灘嘅大鯊魚
吉激咗鯊魚旅游項目

328
00:19:05,520 --> 00:19:08,360
海豹旅游項目也吸引咗大批游客

329
00:19:10,600 --> 00:19:12,360
隨著下水人數嘅增加

330
00:19:12,360 --> 00:19:17,440
對啵度鯊魚捕食習性嘅咗解
變得前所未有嘅重要

331
00:19:20,240 --> 00:19:22,960
嚟自海岸研究中心嘅

332
00:19:22,960 --> 00:19:24,880
海洋生態學家布萊恩雷格爾

333
00:19:25,240 --> 00:19:28,680
與格雷格和梅根合作
一起研究鯊魚行為嘅預測

334
00:19:30,240 --> 00:19:31,200
真唔錯

335
00:19:31,200 --> 00:19:34,200
佢嘅發現系一條重要線索

336
00:19:35,920 --> 00:19:37,960
佢喺追蹤白鯊嘅動向

337
00:19:37,960 --> 00:19:39,960
喺海底和沙洲之上

338
00:19:40,440 --> 00:19:43,400
以前所未有嘅規糢進行著

339
00:19:44,440 --> 00:19:45,920
直至此時

340
00:19:45,920 --> 00:19:49,920
{\an8}我哋才明白咗鯊魚系如何從一個海灘

341
00:19:49,920 --> 00:19:50,840
{\an8}(布萊恩雷格爾)
(海洋生態學家)

342
00:19:50,840 --> 00:19:51,880
{\an8}移動到幾千米外嘅另一個海灘

343
00:19:52,600 --> 00:19:55,720
但作為一個海灘愛掂者,呢仲唔能

344
00:19:56,120 --> 00:19:58,320
告訴我鯊魚和人嘅交集喺邊度

345
00:19:59,360 --> 00:20:03,760
我哋需要一種更精確嘅測量方法

346
00:20:04,240 --> 00:20:06,200
嚟觀察佢哋系如何利用沙洲

347
00:20:06,200 --> 00:20:08,760
海槽、海浪和洋流

348
00:20:09,760 --> 00:20:12,520
布萊恩嘅第一步系進行聲納調查

349
00:20:12,520 --> 00:20:14,840
一覽科德角嘅海底區域

350
00:20:15,600 --> 00:20:16,800
(低窪海灘頭部)

351
00:20:17,800 --> 00:20:22,480
{\an8}呢系科德角迄今為止
最詳細嘅水下地形地圖

352
00:20:23,920 --> 00:20:28,200
通過呢些地圖,佢搵到咗一種方法

353
00:20:28,200 --> 00:20:30,560
嚟實時觀察鯊魚嘅運動

354
00:20:36,920 --> 00:20:40,240
啵度有數千個獨立嘅點

355
00:20:40,240 --> 00:20:42,320
涵蓋咗大約60種唔同嘅鯊魚

356
00:20:42,320 --> 00:20:46,960
喺2021年夏天
每兩個小時就有一條鯊魚出現

357
00:20:48,040 --> 00:20:51,120
每個紅點都表示鯊魚去過嘅地方

358
00:20:52,920 --> 00:20:55,400
我哋能夠確定嘅系

359
00:20:55,400 --> 00:20:57,280
喺呢些淺水區

360
00:20:57,640 --> 00:21:01,000
鯊魚大部分時間都喺

361
00:21:04,720 --> 00:21:08,160
鯊魚喺一個地方嘅行為非常引人註意

362
00:21:09,960 --> 00:21:13,880
呢系一個鯊魚出沒嘅熱點
比其佢任何地方都要活躍

363
00:21:14,240 --> 00:21:17,640
啵度靠近科德角一個最大海豹聚集地

364
00:21:18,400 --> 00:21:19,400
海槽

365
00:21:22,600 --> 00:21:26,320
水流喺啵度形成咗兩個淺沙洲

366
00:21:26,320 --> 00:21:28,800
中間有一條很深嘅溝槽

367
00:21:30,680 --> 00:21:32,240
喺沙子沿著科德角外圍移動時

368
00:21:33,520 --> 00:21:35,800
形成咗兩個平行嘅沙洲

369
00:21:36,560 --> 00:21:39,800
一個靠近海岸,另一個離海岸稍遠

370
00:21:40,440 --> 00:21:41,680
二者中間有一個深槽

371
00:21:43,120 --> 00:21:45,560
喺鯊魚著過呢片區域時

372
00:21:45,560 --> 00:21:47,200
佢哋會利用內側沙洲

373
00:21:47,200 --> 00:21:49,800
沿著底部游向海豹群

374
00:21:50,160 --> 00:21:53,720
咁樣嘅偷襲利用咗海槽縱深

375
00:21:54,120 --> 00:21:58,640
以沙洲做掩體,以渾濁綠水為掩護

376
00:21:59,360 --> 00:22:02,040
咁樣嘅行動並非偶然

377
00:22:03,000 --> 00:22:05,880
大白鯊會沿著海底游動

378
00:22:06,120 --> 00:22:09,320
適應當地環境嚟獵食海豹

379
00:22:10,720 --> 00:22:14,520
呢系世界其佢地方都冇嘅獨特策略

380
00:22:16,680 --> 00:22:19,600
佢哋表現出嘅行為

381
00:22:19,600 --> 00:22:23,200
與我哋喺世界各地
白鯊熱點地區睇到嘅唔同

382
00:22:23,200 --> 00:22:26,800
俾梅根和格雷格提供咗重要新信息

383
00:22:28,840 --> 00:22:32,720
{\an8}科德角可能系世界上大白鯊

384
00:22:32,720 --> 00:22:35,080
{\an8}捕食海豹最具撩戰性嘅地方

385
00:22:38,280 --> 00:22:41,200
佢哋得弄清楚如何喺淺水區生存

386
00:22:41,720 --> 00:22:44,480
如何成功伏擊獵物

387
00:22:45,920 --> 00:22:48,280
所以佢哋必須非常精明才行

388
00:22:49,400 --> 00:22:52,840
我哋通常認為魚唔會學習,但佢哋嘅確會

389
00:22:53,800 --> 00:22:57,720
佢哋有根據經驗進行適應嘅認知能力

390
00:22:58,320 --> 00:22:59,440
我現喺告訴你哋

391
00:22:59,440 --> 00:23:03,320
任何時候白鯊試圖殺死乜嘢嘢

392
00:23:03,640 --> 00:23:06,320
都需要消耗大量嘅能量

393
00:23:08,920 --> 00:23:10,760
如果最後冇足夠嘅能量回報

394
00:23:11,320 --> 00:23:12,440
冇一頓大餐

395
00:23:13,560 --> 00:23:14,840
嗰就系喺嘥能量

396
00:23:16,000 --> 00:23:18,840
如果咁樣嘅情況發生太多
嗰麼佢就無法生存下去

397
00:23:22,960 --> 00:23:27,080
因此即便系經驗豐富嘅鯊魚
也會喺完全確定自己

398
00:23:27,440 --> 00:23:31,560
能成功獵食海豹之前保持克制

399
00:23:34,080 --> 00:23:37,320
嗰些喺啵度成功進食嘅鯊魚
已經搵到咗答案

400
00:23:37,840 --> 00:23:40,520
佢哋要搵到最佳嘅獵食地點

401
00:23:41,400 --> 00:23:43,760
所以我哋試圖弄清楚
佢哋系如何做到呢一點嘅

402
00:23:44,800 --> 00:23:47,840
像美懶懶身上嘅信標咁樣嘅新技術

403
00:23:48,560 --> 00:23:51,960
可能會提供鯊魚
喺發動襲擊前嘅關鍵時刻信息

404
00:23:53,800 --> 00:23:56,560
我哋現喺睇到嘅只系冰山一角,沒錯

405
00:24:07,120 --> 00:24:08,640
已經兩天咗

406
00:24:08,640 --> 00:24:12,360
美懶懶身上嘅信標浮上咗水面

407
00:24:15,240 --> 00:24:17,920
梅根追蹤著無線電信號嚟搵回佢

408
00:24:20,520 --> 00:24:23,080
佢拍下嘅視頻可以幫助解開

409
00:24:23,440 --> 00:24:26,280
大白鯊如何喺科德角捕獵嘅謎團

410
00:24:28,120 --> 00:24:30,280
呢些信標有一個視頻組件

411
00:24:31,040 --> 00:24:33,480
簡直就像系你騎喺一條白鯊嘅孭上

412
00:24:33,480 --> 00:24:36,280
{\an8}所以你可以確切地睇到佢喺做乜嘢

413
00:24:39,240 --> 00:24:43,160
呢真嘅很酷
你可以睇到佢喺多麼淺嘅水域

414
00:24:44,080 --> 00:24:46,320
你可以清楚睇到水面和水底

415
00:24:48,560 --> 00:24:49,480
嚟咗!

416
00:24:50,160 --> 00:24:52,440
佢喺追著乜嘢嘢

417
00:24:53,840 --> 00:24:57,880
呢些動物嘅加速之快令人震驚

418
00:24:57,880 --> 00:24:59,320
非常有力量

419
00:25:00,280 --> 00:25:02,280
呢視頻冇加速

420
00:25:05,840 --> 00:25:08,440
呢系科學家哋最近距離地

421
00:25:08,440 --> 00:25:11,400
從鯊魚嘅角度見證佢嘅捕食過程

422
00:25:13,680 --> 00:25:16,840
美懶懶系能飽餐一頓,仲系挨餓啵?

423
00:25:21,880 --> 00:25:24,680
所以等我哋慢擠美懶懶嘅動作

424
00:25:25,120 --> 00:25:28,960
你就能更清楚睇到佢喺做乜嘢

425
00:25:28,960 --> 00:25:32,200
呢速度快到令人難以置信

426
00:25:32,520 --> 00:25:33,960
但你可以睇到佢就喺嗰度

427
00:25:34,240 --> 00:25:38,200
佢睇到咗乜嘢嘢,然後愣咗一下

428
00:25:39,080 --> 00:25:41,200
就系啵度!佢嘅確愣咗一下才反應過嚟

429
00:25:41,200 --> 00:25:44,840
你可以睇到佢標過去嘅速度有多快

430
00:25:44,840 --> 00:25:47,600
嗰度有一個糢糊嘅影子

431
00:25:48,440 --> 00:25:50,000
實際上系一只海豹

432
00:25:53,160 --> 00:25:56,280
佢嘅孭鰭幾乎要露出水面咗

433
00:25:56,280 --> 00:25:59,000
啵度激起咗一大片水花

434
00:25:59,000 --> 00:26:02,600
然後嗰個深灰色嘅斑點就系一只海豹

435
00:26:02,600 --> 00:26:06,040
你可以睇到佢游得有多快,佢很警醒

436
00:26:06,040 --> 00:26:09,760
佢知道自己喺被一條白鯊追趕

437
00:26:14,360 --> 00:26:15,520
但呢只海豹成功逃走咗

438
00:26:18,080 --> 00:26:21,640
所以呢唔系一次成功嘅捕食

439
00:26:22,640 --> 00:26:26,880
但我哋仍能從呢次行動中學習很多

440
00:26:28,040 --> 00:26:30,840
美懶懶一度非常靠近海豹

441
00:26:30,840 --> 00:26:34,000
你幾乎會惗:「怎麼會失手啵?」

442
00:26:34,000 --> 00:26:38,840
但海豹本身也系一種唔可思議嘅動物

443
00:26:38,840 --> 00:26:40,600
一旦發現有鯊魚向自己撲嚟

444
00:26:40,600 --> 00:26:44,640
佢哋就會迅速做出反應

445
00:26:44,920 --> 00:26:47,720
很多時候佢哋都能逃除

446
00:26:47,960 --> 00:26:50,800
所以我哋從呢些視頻中

447
00:26:50,800 --> 00:26:54,160
唔僅能更加咗解鯊魚嘅捕食行為

448
00:26:54,160 --> 00:26:57,360
也更能咗解到佢哋喺科德角附近水域

449
00:26:57,880 --> 00:27:00,840
成功捕食海豹有多麼艱難

450
00:27:03,680 --> 00:27:08,120
一些本地人認為科德角
唔屬於鯊魚或系海豹

451
00:27:14,240 --> 00:27:15,560
我喺科德角長大

452
00:27:16,080 --> 00:27:18,320
我做咗21年嘅職業漁民

453
00:27:19,040 --> 00:27:20,520
喺我小嘅時候

454
00:27:20,520 --> 00:27:22,400
海豹系很罕見嘅動物

455
00:27:23,200 --> 00:27:26,240
但現喺嘅問題系,佢哋嘅數量太多咗

456
00:27:26,240 --> 00:27:28,680
{\an8}佢哋正喺摧毀整個魚類種群

457
00:27:28,680 --> 00:27:29,960
{\an8}(尼克穆托)
(職業漁民)

458
00:27:29,960 --> 00:27:33,120
{\an8}損壞生態系統
損壞我哋啵度脆弱嘅生態系統

459
00:27:34,600 --> 00:27:36,960
捕魚系科德角文化和魅力嘅一部分

460
00:27:37,360 --> 00:27:40,600
佢嘅名字也源自
啵度曾經盛產嘅鱈魚英文名

461
00:27:41,640 --> 00:27:44,720
由於幾十年嚟嘅過度捕撈
魚類數量下降咗

462
00:27:45,040 --> 00:27:47,920
漁民搵食變得更加眼瞓難

463
00:27:49,040 --> 00:27:51,160
很多人將之歸咎於海豹

464
00:27:53,560 --> 00:27:54,720
最重要嘅系

465
00:27:54,720 --> 00:27:57,920
啵度嘅海豹直接影嚮到咗我嘅底線

466
00:27:58,520 --> 00:27:59,920
我嘅生活

467
00:27:59,920 --> 00:28:03,360
我嘅家庭、我嘅生意、佢造成咗很多損失

468
00:28:04,640 --> 00:28:08,120
因為現喺啵度有很多海豹
佢哋吸引咗白鯊

469
00:28:08,960 --> 00:28:11,480
呢就使得人哋下水變得危險

470
00:28:12,960 --> 00:28:14,760
現喺要系我嘅囡囡

471
00:28:15,120 --> 00:28:18,360
進入到海水里
嗰佢就嘅確面臨著生命危險

472
00:28:22,360 --> 00:28:26,240
許多人認為鯊魚和海豹
系最近才出現喺啵度

473
00:28:27,160 --> 00:28:29,560
但本地嘅瑪許比萬帕諾亞格人

474
00:28:29,560 --> 00:28:33,560
已經與海豹和鯊魚共存咗幾個世紀

475
00:28:35,480 --> 00:28:37,640
啵度嘅水供養咗我哋幾千年

476
00:28:38,760 --> 00:28:42,120
海豹系我哋嘅文化非常依賴嘅存喺

477
00:28:43,000 --> 00:28:45,600
{\an8}人哋話海豹系新嚟者,鯊魚系新嚟者

478
00:28:45,600 --> 00:28:46,880
{\an8}(大衛威登)
(瑪許比萬帕諾亞格部落族人)

479
00:28:46,880 --> 00:28:49,680
{\an8}呢與历史上嘅文字記載唔一致

480
00:28:50,120 --> 00:28:53,320
也與部落啖述嘅历史唔一致

481
00:28:54,920 --> 00:28:57,040
海豹和鯊魚系回歸啵度

482
00:28:57,360 --> 00:28:59,600
大自然母親非常強大

483
00:28:59,600 --> 00:29:03,000
睇到野生動物回歸

484
00:29:03,640 --> 00:29:06,960
意味著呢些動物都有食物嚟源

485
00:29:07,800 --> 00:29:09,560
萬物相互依賴

486
00:29:09,880 --> 00:29:11,680
呢就系我哋嘅信仰體系

487
00:29:11,920 --> 00:29:15,320
萬物都有生存嘅權利

488
00:29:16,400 --> 00:29:18,360
所以我哋必須尊重佢哋嘅存喺

489
00:29:18,960 --> 00:29:21,840
佢哋會喺特定嘅季節嚟到啵度

490
00:29:21,840 --> 00:29:24,360
就像我哋允許游客嚟到我哋嘅街道

491
00:29:24,360 --> 00:29:30,040
打擾本地人一樣

492
00:29:31,680 --> 00:29:32,920
我哋會耐心地對待游客

493
00:29:34,080 --> 00:29:36,680
所以我哋都要對
所有生物保持正念和耐心

494
00:29:36,680 --> 00:29:39,920
包括鯊魚、海豹、所有生物

495
00:29:44,720 --> 00:29:47,960
灰海豹系科德角最常見嘅海豹

496
00:29:49,360 --> 00:29:54,080
佢哋可以長到
3米長,重達近400千克

497
00:29:57,280 --> 00:29:58,960
喺陸地上佢哋很笨拙

498
00:29:59,600 --> 00:30:02,520
但喺水中,佢哋唔受重力影嚮

499
00:30:07,160 --> 00:30:09,000
佢哋掂奇又愛玩

500
00:30:10,480 --> 00:30:12,120
科德角周圍嘅水域

501
00:30:12,600 --> 00:30:15,960
富含佢哋鍾意食嘅魚類和甲殼類動物

502
00:30:18,200 --> 00:30:21,440
啵度全年都系灰海豹嘅天堂

503
00:30:25,440 --> 00:30:27,720
但只要佢哋進入水里

504
00:30:28,600 --> 00:30:29,680
佢哋就很易受到傷害

505
00:30:32,680 --> 00:30:37,840
一次與鯊魚嘅接觸
俾呢只海豹留下咗可怕嘅傷啖

506
00:30:40,200 --> 00:30:43,400
盡管海豹有足夠嘅恢複能力

507
00:30:44,000 --> 00:30:48,280
但下一次入水仍可能意味著死亡

508
00:30:50,760 --> 00:30:55,560
灰海豹每天必須食掉相當於
其體重百分之六嘅食物才能活下去

509
00:30:57,680 --> 00:30:59,520
所以冇時間恢複咗

510
00:31:01,480 --> 00:31:04,280
佢必須回到水里進食

511
00:31:13,920 --> 00:31:17,920
因鯊魚攻擊而造成嘅
身子鼓脹可能會要咗呢只海豹嘅命

512
00:31:20,160 --> 00:31:22,880
無法潛水就意味著無法進食

513
00:31:23,640 --> 00:31:27,240
佢成咗活靶子,佢冇被忽視

514
00:31:43,160 --> 00:31:45,240
但系鯊魚冇發動攻擊!

515
00:31:48,160 --> 00:31:51,640
呢些動物總系讓人震驚,對吧?

516
00:31:51,640 --> 00:31:54,240
佢哋系大型捕食者嘎?

517
00:31:54,840 --> 00:31:58,120
很多人認為佢哋系無意識嘅進食機器

518
00:32:01,120 --> 00:32:03,200
相較於冇頭腦嘅殺手

519
00:32:03,480 --> 00:32:06,160
呢些大白鯊也會撩食嘎?

520
00:32:07,360 --> 00:32:12,320
呢與你通常喺電視
或電影中睇到嘅非常唔同

521
00:32:12,920 --> 00:32:14,760
呢真嘅讓我很震驚

522
00:32:17,360 --> 00:32:20,320
呢系留待嚟年鯊魚季嘅問題

523
00:32:21,800 --> 00:32:23,760
隨著夏季接近尾聲

524
00:32:24,840 --> 00:32:29,080
大白鯊向南遷徙到佛羅里達以躲避寒冷

525
00:32:33,000 --> 00:32:37,320
冬天,一種荒涼嘅美籠罩著科德角

526
00:32:37,760 --> 00:32:40,760
雪落喺空蕩蕩嘅避暑別墅上

527
00:32:46,920 --> 00:32:48,280
但對灰海豹嚟話

528
00:32:48,800 --> 00:32:51,800
呢系一年中最重要嘅時刻

529
00:32:54,560 --> 00:32:56,800
佢哋喺啵度養育後代

530
00:32:58,680 --> 00:32:59,840
喺11個月後

531
00:33:00,280 --> 00:33:04,400
乸灰海豹只會生下一只幼崽

532
00:33:05,160 --> 00:33:08,720
幼崽出生時體重約16千克

533
00:33:09,200 --> 00:33:10,920
但喺接下嚟嘅三周里

534
00:33:10,920 --> 00:33:12,960
喝著母親濃鬱嘅乳汁

535
00:33:13,280 --> 00:33:15,680
佢每天會增重大約1.4千克

536
00:33:16,640 --> 00:33:17,680
喺此期間

537
00:33:17,680 --> 00:33:20,600
海豹母親唯一嘅工作
就系照顧自己嘅幼崽

538
00:33:21,800 --> 00:33:24,440
佢唔會離開佢嘅幼崽
即使系喺食嘢嘅時候

539
00:33:26,360 --> 00:33:29,560
呢對母親和幼崽嚟話都很危險

540
00:33:30,520 --> 00:33:32,880
所以佢哋會定居喺科德角外側

541
00:33:32,880 --> 00:33:35,360
呢個僻靜嘅海灘上過冬

542
00:33:43,720 --> 00:33:49,080
生物學家安德烈波格莫爾尼
監測著佢哋喺環境中扮演嘅角色

543
00:33:51,400 --> 00:33:54,600
人哋對灰海豹有一些誤解

544
00:33:54,600 --> 00:33:56,360
特別系喺呢個地區

545
00:33:56,360 --> 00:33:59,440
{\an8}一個系認為佢哋食掉咗所有嘅魚
唔系一些魚,系所有魚

546
00:33:59,440 --> 00:34:00,360
{\an8}(安德烈波格莫爾尼)
(生物學家)

547
00:34:00,360 --> 00:34:02,080
{\an8}但事實並非如此

548
00:34:03,760 --> 00:34:05,400
佢哋會食很多嘢

549
00:34:07,000 --> 00:34:10,000
佢哋嘅食物系呢些小魚

550
00:34:10,520 --> 00:34:14,080
研究表明海豹糞便中嘅氮

551
00:34:14,080 --> 00:34:16,680
系本地海灘草嘅肥料

552
00:34:16,680 --> 00:34:19,240
有助於穩定沙丘

553
00:34:19,240 --> 00:34:22,240
保護呢片區域免受風暴潮嘅影嚮

554
00:34:26,160 --> 00:34:29,000
嚟自海灘上海豹糞便中嘅氮

555
00:34:29,000 --> 00:34:32,000
實際上有助於海灘草嘅生長

556
00:34:32,320 --> 00:34:35,520
所以生態系統可能會以完全

557
00:34:35,520 --> 00:34:37,560
意惗唔到嘅方式發生變化

558
00:34:37,560 --> 00:34:40,320
因為呢些動物回到咗啵度

559
00:34:41,200 --> 00:34:42,560
呢很令人興奮

560
00:34:53,360 --> 00:34:54,400
等到咗春天

561
00:34:54,400 --> 00:34:58,360
海豹老媽子和佢哋嘅孩子回到海里覓食

562
00:35:05,240 --> 00:35:07,360
鯊魚也翻嚟咗

563
00:35:08,440 --> 00:35:09,880
佢哋饑腸轆轆

564
00:35:13,560 --> 00:35:15,440
喺長途北上之後

565
00:35:15,440 --> 00:35:17,720
佢哋必須補充脂肪儲備

566
00:35:21,560 --> 00:35:24,480
而喺附近淺水區漂流嘅獵物

567
00:35:25,920 --> 00:35:30,200
系呢條雄性鯊魚唔能錯過嘅機會

568
00:35:31,920 --> 00:35:35,200
但啵度水深只有60厘米,呢很危險

569
00:35:38,120 --> 00:35:40,360
呢系一個危險嘅場景,呢條鯊魚體型很大

570
00:35:40,360 --> 00:35:43,120
體重可能超過450千克

571
00:35:47,720 --> 00:35:49,680
大魚唔鍾意淺水區

572
00:35:49,680 --> 00:35:52,480
尤其系喺有水流或波浪

573
00:35:52,480 --> 00:35:54,120
會把佢哋推向更淺水位嘅地方

574
00:35:55,680 --> 00:35:59,000
佢很可能擱淺喺海灘上

575
00:36:05,320 --> 00:36:07,040
呢系鯊魚嘅一場賭博

576
00:36:07,760 --> 00:36:10,800
唔管遇到乜嘢眼瞓難
呢只海豹都要遭殃咗

577
00:36:11,760 --> 00:36:12,920
喺啵度危險嚟自低水位

578
00:36:15,440 --> 00:36:17,040
啵度對大魚嚟話可唔系個掂地方

579
00:36:18,640 --> 00:36:21,640
人哋冇意識到鯊魚冇倒擋裝置

580
00:36:22,000 --> 00:36:24,320
佢哋只能向前移動

581
00:36:25,400 --> 00:36:29,400
一波巨浪就可能
把佢推到無法回頭嘅地步

582
00:36:32,000 --> 00:36:35,120
佢哋唔能像人嗰樣後退
所以如果鯊魚到咗海灘上

583
00:36:35,120 --> 00:36:37,800
佢就只能通過唔停扭動

584
00:36:37,800 --> 00:36:41,080
嚟轉身離開

585
00:36:45,920 --> 00:36:50,960
如果唔能做到,佢哋就會死喺海灘上

586
00:37:03,680 --> 00:37:04,840
喺標浪中捕食

587
00:37:05,160 --> 00:37:08,080
呢條鯊魚幾乎除離咗水面!

588
00:37:09,240 --> 00:37:11,720
呢系冇被記錄過嘅影像

589
00:37:15,960 --> 00:37:17,720
利用肌肉發達嘅尾巴

590
00:37:18,040 --> 00:37:21,200
鯊魚掙紮著回到水里

591
00:37:28,640 --> 00:37:31,480
佢拖著海豹離開咗危險區域

592
00:37:33,560 --> 00:37:35,760
佢終於可以大食一頓咗!

593
00:37:37,920 --> 00:37:40,240
呢場騷動並冇被忽視

594
00:37:42,280 --> 00:37:46,800
又有兩條鯊魚靠咗過嚟

595
00:37:48,320 --> 00:37:50,920
大白鯊一般被認為系獨居動物

596
00:37:54,360 --> 00:37:58,040
我哋嘅新發現系
睇到咗多條鯊魚一起捕食

597
00:37:59,560 --> 00:38:01,280
喺占主導地位嘅鯊魚離開後

598
00:38:01,280 --> 00:38:04,760
體型略小一級嘅鯊魚就會靠近

599
00:38:05,120 --> 00:38:08,760
喺另外嗰條鯊魚翻嚟前迅速咬上一啖

600
00:38:10,560 --> 00:38:14,400
多只鯊魚合作捕食嘅記錄很少

601
00:38:16,040 --> 00:38:18,520
呢系第一次喺科德角睇到

602
00:38:20,720 --> 00:38:25,560
令人驚訝嘅新研究表明
鯊魚比以往惗象嘅更善於社交

603
00:38:27,040 --> 00:38:30,640
人哋認為大白鯊系獨居動物

604
00:38:30,920 --> 00:38:33,680
唔系特別聰明

605
00:38:33,680 --> 00:38:36,440
鯊魚被認為系游動嘅嗅覺動物

606
00:38:36,440 --> 00:38:39,640
就系一直喺尋搵著下一餐

607
00:38:39,920 --> 00:38:42,520
但科學家哋才剛剛開始咗解

608
00:38:42,520 --> 00:38:45,240
鯊魚呢些複雜嘅社會互動

609
00:38:49,240 --> 00:38:52,880
睇到呢三條鯊魚喺進食時互相讓步

610
00:38:52,880 --> 00:38:57,200
就像喺跳舞一樣

611
00:38:59,480 --> 00:39:02,200
老實話呢讓我大受震撼

612
00:39:05,600 --> 00:39:06,960
佢哋冇爭鬥

613
00:39:07,280 --> 00:39:09,040
冇纏鬥到一起

614
00:39:09,280 --> 00:39:10,880
呢真嘅很令人驚訝

615
00:39:12,000 --> 00:39:15,160
我哋喺科德角從未見過呢種行為

616
00:39:19,360 --> 00:39:21,520
呢條巨大嘅、成功嘅雄性鯊魚

617
00:39:21,520 --> 00:39:23,920
甚至可能系佢哋認識嘅鯊魚

618
00:39:31,080 --> 00:39:33,440
我惗我哋可以從喺場嘅三條鯊魚中

619
00:39:33,440 --> 00:39:35,880
辨認出嗰條大鯊魚

620
00:39:36,320 --> 00:39:39,520
嗰條鯊魚離海灘很近,水也很淺

621
00:39:41,640 --> 00:39:44,000
我哋可以清楚地睇到佢嘅一些紋理

622
00:39:44,720 --> 00:39:46,440
和孭鰭嘅邊緣

623
00:39:46,440 --> 00:39:48,480
每個鯊魚都唔一樣

624
00:39:48,480 --> 00:39:51,280
有點像系人類嘅指紋

625
00:39:51,800 --> 00:39:55,040
有時候你可以睇到尾巴上嘅紋理

626
00:39:55,760 --> 00:39:57,560
有些非常明顯嘅凹痕

627
00:39:59,280 --> 00:40:01,520
現喺我睇咗呢段視頻

628
00:40:01,520 --> 00:40:03,720
我百分之百確定

629
00:40:04,080 --> 00:40:07,040
呢就系白鯊美懶懶

630
00:40:07,840 --> 00:40:11,240
佢喺2014年被首次發現

631
00:40:11,680 --> 00:40:13,520
-準備掂翻
-掂嘅!

632
00:40:13,960 --> 00:40:15,280
更酷嘅系

633
00:40:15,640 --> 00:40:19,880
去年夏天美懶懶接收咗相機信標

634
00:40:22,400 --> 00:40:26,120
我哋見過佢追擊一只海豹嘅樣子

635
00:40:28,280 --> 00:40:31,440
嗰畫面令人驚嘆,可惜佢當時失敗咗

636
00:40:33,840 --> 00:40:34,920
但系今年佢冇失敗

637
00:40:35,280 --> 00:40:38,440
喺科德角海岸捕獵海豹並唔容易

638
00:40:38,800 --> 00:40:42,680
佢年複一年地嚟到啵度

639
00:40:42,680 --> 00:40:48,120
話明佢已經知道如何
喺呢個地區成功地捕獵海豹

640
00:40:49,040 --> 00:40:51,520
一年又一年地學習!

641
00:40:52,480 --> 00:40:54,840
佢學會咗駕馭呢個環境

642
00:40:54,840 --> 00:40:57,320
呢真系令人激動

643
00:40:58,560 --> 00:41:04,240
但美懶懶只系年複一年
翻嚟啵度嘅眾多白鯊之一

644
00:41:06,840 --> 00:41:10,240
從嚟冇人對西北大西洋嘅
白鯊數量進行過估計

645
00:41:11,120 --> 00:41:13,280
呢系地球上最神秘嘅

646
00:41:13,280 --> 00:41:14,840
白鯊種群之一

647
00:41:15,960 --> 00:41:19,720
所以創建呢個鯊魚目錄嘅動機

648
00:41:20,680 --> 00:41:23,280
唔僅僅系為咗識別呢些個體

649
00:41:24,480 --> 00:41:27,200
實際也系惗要知道

650
00:41:27,480 --> 00:41:30,000
有幾多白鯊嚟到科德角

651
00:41:31,680 --> 00:41:33,600
現喺梅根和格雷格

652
00:41:33,600 --> 00:41:37,440
第一次掌握咗呢個地區嘅鯊魚總數

653
00:41:38,920 --> 00:41:41,280
佢遠遠高於預期

654
00:41:43,240 --> 00:41:47,440
我哋估計喺五年嘅時間里

655
00:41:47,440 --> 00:41:51,480
有八到九百條白鯊嚟到科德角水域

656
00:41:53,000 --> 00:41:55,280
呢真系唔可思議

657
00:41:57,320 --> 00:42:02,520
近九百條大白鯊嚟到科德角嘅海灘

658
00:42:02,520 --> 00:42:05,440
使其成為世界上最大白鯊分布區之一

659
00:42:05,440 --> 00:42:09,360
可能也系白鯊密度最大嘅地區之一

660
00:42:14,400 --> 00:42:17,240
格雷格、梅根和布萊恩嘅
突損性嘅研究表明

661
00:42:18,320 --> 00:42:20,680
呢些鯊魚比人哋認為嘅更聰明

662
00:42:21,440 --> 00:42:22,680
更群居

663
00:42:23,600 --> 00:42:24,800
更撩剔

664
00:42:25,720 --> 00:42:29,800
而且喺科德角嘅白鯊數量
遠遠高過以往認知

665
00:42:32,840 --> 00:42:36,440
但系呢些信息要
如何幫助人哋保持安全啵?

666
00:42:38,640 --> 00:42:41,000
呢系一個非常受歡迎嘅游泳海灘

667
00:42:41,680 --> 00:42:44,840
可以話系科德角最受歡迎嘅海灘之一

668
00:42:47,000 --> 00:42:51,440
但我喺距離海岸線
6米嘅地方標記過白鯊

669
00:42:53,800 --> 00:42:56,520
因此我哋現喺正喺進行嘅研究

670
00:42:56,520 --> 00:42:57,920
系研究鯊魚喺邊度捕獵

671
00:42:58,640 --> 00:42:59,720
佢哋如何獵食

672
00:43:01,040 --> 00:43:03,360
以及佢與環境嘅關系

673
00:43:04,200 --> 00:43:07,080
以搵到可預測性嘅行為糢式

674
00:43:08,000 --> 00:43:10,800
就像鯊魚活動嘅天氣報告

675
00:43:14,640 --> 00:43:16,920
有健康嘅鯊魚種群

676
00:43:18,680 --> 00:43:20,160
健康嘅海豹種群

677
00:43:21,360 --> 00:43:24,120
呢種捕食者和獵物嘅關系發生喺啵度

678
00:43:24,880 --> 00:43:26,080
系一件掂事

679
00:43:28,000 --> 00:43:31,160
呢系自然生態系統嘅恢複

680
00:43:32,040 --> 00:43:34,720
{\an8}保護工作得到咗回報

681
00:43:35,840 --> 00:43:36,760
{\an8}呢就系我哋嘅目嘅

682
00:43:36,760 --> 00:43:39,480
{\an8}我哋需要一個平衡嘅海洋生態系統

683
00:43:40,760 --> 00:43:43,840
{\an8}呢將使野生動物即使

684
00:43:44,120 --> 00:43:48,760
{\an8}喺人類聚居嘅地方也能繼續繁衍生息

685
00:43:50,240 --> 00:43:51,880
{\an8}我哋現喺正喺努力提供呢些信息

686
00:43:51,880 --> 00:43:54,760
{\an8}希望能喺未嚟幫助拯救生命

687
