鲸鱼的秘密（2021）第一季 第四集

这一点超级重要
and that’s super important.
没有统一的黄金法则
And we can’t, you know, there’s no golden rule across the board,
我们不能说多米尼克的抹香鲸这样做
we can’t say sperm whales in Dominica do this
它们可以这样受到保护
so they can be protected like this
因此我们就应该以同样的方式 或采取同样的举措
therefore, we should protect all sperm whales
来保护所有的抹香鲸
in the same way or take the same measures.
这是显而易见的
Even from the surface it’s apparent.
我们一开始看到这里的抹香鲸
From the very first second we saw sperm whales here
立刻就发现非常不一样
it was immediately clear that things are very different.
这里常见的东西 在加勒比地区却很罕见
What’s common here is rare in the Caribbean.
好多啊
There’s so many.
如果你在多米尼克像这样观察一天
If you looked at a day like this in Dominica,
我想15年来我们只有两天
I think we’ve had two in 15 years
-观察到有这么多的鲸鱼 真的吗？
-where there’s this many animals. Oh, really?
布赖恩希望找到一些线索 看看发生了什么
Brian hopes to find some clues as to what’s going on.
-拍到了吗？ 谢谢
-Got it? Thanks.
为什么有如此盛大的派对？
Why the big party?
一跳进水里 我就听到这种刺耳的声音
As soon as I jump in the water I here this cacophony of sound.
我能看到12至18头鲸鱼
I can see between 12 and 18 whales
有些在休息 笔挺的身躯像是林中的树木
and some are resting like trees in a forest.
有的则平躺着
Others are sort of horizontal.
虽有入侵者破坏它们的乐趣 但这些鲸鱼却不以为意
These whales aren’t thrilled to have an intruder crash their fun.
它们没有攻击性
They’re not aggressive
但还是用它们认为最有效的方式
but they let Brian know he’s not exactly welcome. . .
让布赖恩知道它们并不欢迎他
in the best way they know how.
鲸鱼粪便
Whale poop.
鲸鱼在水柱顶部“施肥”
Whales fertilize the top of the water column
促进浮游生物生长
boosting plankton growth.
不仅能喂养鱼类
That feeds fish. . .
甚至有助于对抗气候变化
and it even helps combat climate change.
这种行为也是一次机会
This act is also an opportunity.
就是这里 你可能可以捞到
It’s right here. You might actually be able to get it.
对
Yeah. It’s squid, look. Yeah.
太酷了 可以看到 这条乌贼腿底部的吸盘
Super cool, you can see the suction cups on the bottom of this squid leg.
阿沙打捞起粪便 想看看这些抹香鲸吃些什么
Asha scoops the poop to find out what these sperm whales eat.
我们发现一个乌贼的喙
So, right here, we have a squid beak
这是我们 从一些抹香鲸粪便中捞出来的
that we fished out of some of the sperm whale poop.
不同的种群有不同的饮食习惯
Different clans have different dietary habits,
一旦分♥析♥出这个 我们就能感觉出
so, once we analyze these we’ll get a bit of a sense of the differences
斯里兰卡和多米尼克的 抹香鲸之间有区别
between here in Sri Lanka and some of the sperm whales out in Dominica.
谢恩·杰罗的方法靠的是声音
Shane Gero’s methods rely on sound.
把水中听音器放到水里 激动人心的事情就发生了
When you put the hydrophone in the water that’s where the exciting stuff happens.
他将首次听到抹香鲸的
He’s about to hear their live communications
交流现场
for the first time.
他将了解到斯里兰卡的抹香鲸 跟“希望”和多米尼克的其他抹香鲸
He’ll learn if Sri Lankan whales speak the same language as Hope. . .
是否讲同一种语言
and the other whales of Dominica.
这和我们在多米尼克看到的大不相同
That’s a massive difference than what we’ve seen off Dominica.
部分原因是它们属于这个地方
Part of that is that they belong here.
它们在暗示自己来自这里
and they are signaling that this is where they’re from.
这是一种完全不同的语言
This is an entirely different language.
一个种群有自己独特的文化
A clan with its own unique culture.
但抹香鲸在各地面临的挑战 都是一样的
But the challenges sperm whales face everywhere are the same.
这头鲸的下颌少了一部分
This whale is missing part of its jaw.
不难猜到这是怎么发生的
It’s not hard to guess how it happened.
附近海龟的遭遇就是明显的答案
The turtles around here make it obvious.
人类制♥造♥的垃圾 可能杀死任何海洋动物
Human debris can be a killer for any marine animal.
确保我在这块垃圾后面
And make sure I get behind this debris. . .
《国家地理》的潜水员们 尽可能多地去拯救海龟
The National Geographic divers save as many turtles as they can.
对
Yeah.
-好 我先把这只蠵龟救出来 好
Okay, let me get the log off first.
很幸运 它身上没有被勒伤
It’s lucky, it doesn’t look like it’s dug in anywhere.
准备好了吗？
Ready?
好了
Okay. Okay. Okay.
-这是我救出来的第三只了 是啊
-That’s the third one that I’ve cut out. Yup.
如果你说你也看到过
And if you’re saying you’ve seen
-同样的情况 对
-the same. Yeah.
我们在水上的时间很多
I mean, we spend a lot of time on the water
-但是 真的太多了 但还是很多
-but that’s way too many. But still.
-就是太多了 对 是啊
-That’s way too many, yeah. Yeah.
现在他们开始担心 “希望”存活的机会
Now they are anxious about Hope’s chances
还有多米尼克的濒危种群
and her endangered clan in Dominica.
回到他们调查开始的地方
Back to where their investigation started.
多米尼克
谢恩已经一年多没见过“希望”了
It’s been more than a year since Shane has seen Hope.
听起来我们很疯狂 因为…
We sound crazy because. . .
它对家族的存亡至关重要
She is critical to her family’s survival.
要是它还活着 那就太好了
If she’s still alive.
但有些奇怪的事情发生了 不寻常的骚动
But something strange is going on. Unusual commotion.
这里的鲸群通常是小家庭
The resident groups here are usually small families,
雌鲸带着幼崽一起玩
moms hanging with their kids.
但现在整个种群的雌鲸都聚到一起了
But now, females from throughout the clan have come together.
这可能预示着出了问题
It could indicate that something is wrong.
虽然还没有小家伙“希望”的踪迹
While there’s no sign yet of baby Hope. . .
但发现一个访客
there is a visitor.
一个外来者
An outsider.
它魅力非凡
And he’s quite the sex symbol.
一些雄性幼鲸也崇拜这位巨星
Some young males also admire this superstar.
在这里鲜少有雄鲸 能够吸引来这么多粉丝
It’s rare here for a male to attract so many fans.
雌鲸们将决定它可以跟谁交♥配♥
The ladies will decide who he gets to mate with.
而不是由它做主
Not him.
但首先 来个鲸鱼式的拥抱
But first, the whale equivalent of a hug.
它们喜欢这位陌生者的触摸
They enjoy the stranger’s touch.
它比一辆公交车还大
Bigger than a bus.
像羔羊一样敏感
As sensitive as a lamb.
现在它们排成队形游弋
Now, they swim in formation.
这位外来者来自另一个种群
This outsider is from another clan.
或许是另一片海洋
Maybe another ocean.
它将扩充此地抹香鲸的基因库
He will boost the gene pool of the sperm whales here.
但是科学家谢恩·杰罗还是担心
But scientist Shane Gero is still concerned.
太多鲸鱼因被渔具缠绕而死亡
Too many have died from entanglements in fishing gear.
小家伙“希望” 可能也遭遇了同样的命运
Baby Hope may have suffered the same fate.
好吧 有一头幼鲸来到了船的左舷处
All right. So you have a juvenile here, coming on the port side of the boat.
-好吧 成年鲸鱼尾随其后
Okay. And then the adult’s back here.
对
Right.
他们继续搜索
They search on.
如果“希望”还活着
If she’s still alive,
“希望”就是这个种群独特的文化 存活下去的最后机会之一
Hope is one of the last chances for this clan’s unique culture to survive.
有没有另一头的踪迹 队长？
It’s definitely a sign. You seeing them, chief?
等等
Hold on, hold on.
他们都要去吗？ 我们要跟幼鲸一起吗？
Are they both gonna go? Are we gonna get calf with. . . ?
然后…
Then. . .
它在那边
there she is.
太好了！
Yeah!
谢恩立刻就认出了它身上的斑纹
Shane recognizes her markings instantly.
“希望”安然度过了关键的头两年
Hope has survived her first two crucial years.
哇 它长大了
Wow, she’s so grown up.
哇！它长得好大！
Wow! She’s huge!
跟抹香鲸待在一起数千个小时后
The big take home that I’ve gotten from spending thousands of hours
我得到的最大收获就是群落的力量
in the company of sperm whales is the power of community.
你觉得哪里最自♥由♥自在 哪里最有归属感
Where you feel most at home and most belong
这对任何东西都很重要 无论鲸鱼还是人类皆如此
is really important to anything, whether you’re a whale or a human.
如果我们想要保护生命 无论是人类还是鲸鱼的生命
If we’re going to preserve life, whether it’s ours or theirs,
保护文化多样性至关重要
it’s really important that we protect cultural diversity
在我们自己的社会 和整个生态系统中皆如此
both in our own societies and the ecosystem as a whole.
关于抹香鲸文化 我们还有很多需要学习
We still have much to learn about sperm whale culture.
但我们通过其他鲸鱼物种知道 每个种群都占据着一个重要的生态位
But we know from other whale species that each clan fills a vital niche.
虎鲸家族根据自己的生活环境
Orca families have very specific hunting skills
有相应的捕猎技能
depending on where they live.
白鲸使用复杂的语言
Belugas use complex language
教幼鲸们了解传统的繁殖地
and teach their young about traditional birthing grounds.
一些雄性座头鲸 每年都会创作一首新歌♥曲
