琵琶鱼

All About Anglerfish

你知道地球上大约有
Did you know that about 70 %
70%是被水覆盖的吗
of our planet is covered by water?
这比我们所居住的半个地球的面积还要大
That’s more than half the world we live in!
并且海洋中充满了各种各样神奇的动物
And the oceans are just full of all kinds of amazing living things.
我们已经告诉过你有海豚 企鹅甚至是水滴鱼
We’ve already told you about animals like dolphins and penguins and even the blowfish.
不过你有听说过琵琶鱼吗?
But have you ever heard of the anglerfish?
请做好准备…… 这就是琵琶鱼
OK, prepare yourself … this is an anglerfish.
哎呀!
Yikes!
世界上有超过两百多种的琵琶鱼
There are more than 200 different kinds of anglerfish,
并且大多数琵琶鱼
and most of them can be found
都生活在世界上一些最深的海域里
in some of the deepest waters in the world —
特别是大西洋
especially in the Atlantic Ocean.
琵琶鱼得名于它头上的一条长线
The anglerfish gets its name from a long strand that grows
这条长线名字叫做“诱饵”
from its head, called a lure.
它的用途有点像钓鱼竿
And it uses the lure like a fishing rod—sortof.
这个“诱饵”的末端会像电灯泡一样发光
The end of the lure actually glows like a light bulb,
光线会吸引其它好奇的鱼类
and its light attracts other curious fish
被吞进琵琶鱼的嘴里
right into the mouth of the anglerfish!
这使得琵琶鱼成为了一种会捕鱼的鱼
This makes the anglerfish a fish that kindof… fishes!
但是让琵琶鱼如此奇特不仅仅是它会发光的诱饵
But that glowing lure isn’t the only thing that makes anglerfish so special.
比如说
For example!
我提到过 琵琶鱼生活在深海里
I mentioned that anglerfish live deep in theocean.
而许多琵琶鱼居住在最冷
But many of these animals live in the coldest,
最深层的海底 那里被称为漆黑地带
deepest layer of the ocean, known as the midnight zone.
你可能从这个名字里就能猜到
As you might have guessed from its name,
深层带是完全漆黑的
the midnight zone is completely dark.
这是因为海水层
That’s because this layer of the ocean
深到没有阳光能照射进来
is so deep that it gets no sunlight!
所以这些深海生物往下能看到的唯一光源
So the only light that animals see down there
就是某些生物所发出的特殊光源
is the special light that’s given off by certain living things
比如拥有发光诱饵的琵琶鱼
like the anglerfish,with its glowing lure.
当深海生物比如小鱼
And when some deep-sea creatures, like little fish,
看到诱饵散发出来的光亮时 它们会游过去
see the light of that lure, they swim up
想看得更清楚一些
to get it a better look.
这就是琵琶鱼的另一个有意思的知识
Which leads us to another cool thing aboutanglerfish: With the help of their lure, they’re really,
在小灯笼的帮助下 琵琶鱼真的是很优秀的猎手
really good hunters.
琵琶鱼经常躲在沙子里 露出“小灯笼”
Anglerfish often hide in the sand and stick out their lure,
然后等候猎物上门
and then wait for their prey.
一旦别的生物靠得很近…咔嚓!
Once another animal gets close enough, then… CHOMP!
有趣的是 琵琶鱼能吃下比它们体型大两倍的生物
And a really need thing is, anglerfish can eat animals twice their size.
它们是怎样把那么大的东西装进腹部的?
How can they fit something that big into theirbellies?
琵琶鱼有很大的嘴巴 和十分灵活有弹性的身体
Well, Anglerfish have huge mouths, and really flexible stretchy bodies,
所以它们才能整个吞下去
so they can swallow a whole lot!
几乎没有生物能吃掉琵琶鱼
And almost nothing can eat an anglerfish.
据我们所知 琵琶鱼几乎没有天敌
They have very few predators that we know about.
你还想知道一件和琵琶鱼有关的趣事吗
Do you wanna know one more cool thing about anglerfish?
雌性琵琶鱼占据统治地位
The girls really rule.
只有雌性琵琶鱼头上才有特殊的诱饵
Only the female anglerfish have that special lure on top of their heads.
并且它们比雄性琵琶鱼大很多
The females are also much bigger than the males.
有的雄性琵琶鱼和你的食指一样小
And males are sometimes as small as your pointerfinger.
事实上 它们小到
In fact, they’re so tiny,
雌性可以背着雄性到处转悠
that females carry the males around!
这是因为雄性成年后无法养活自己
This is because the males can’t feed themselves when they become adults,
所以它们必须得抓住雌性琵琶鱼
so they have to latch onto a female
用牙齿咬住她们不放
by biting her and holding on with their teeth.
人们曾经发现一些雌性琵琶鱼身上同时附有六条雄性琵琶鱼!
Some females have been seen carrying up to six males at a time!
女士们 干得漂亮!
Nice work, ladies!
现在你们知道:琵琶鱼是居住在深水里 黑暗中会发光的绝佳猎手
So now you know: Anglerfish are deep-dwelling,glow-in-the-dark, A-plus hunters
并且它们也是生存在海洋里的
And anglerfish are just some of the fascinating creatures that live
有趣生命之一
in our amazing oceans.
