Whoa, Squeaks, what were you looking at?
哇，吱吱，你在看什么？
Squeaks says he’s learning about different kinds of animals.
吱吱说他正在学习不同种类的动物。
And he’s noticed that a lot of animals have whiskers.

Yes, cats have whiskers.

Yep, you too, Squeaks!
是的，你也有，吱吱！
Even seals have whiskers!

Do you have any idea what whiskers might be for, Squeaks?
你知道胡须是用来做什么的吗，吱吱？
You’re right - they do look cute with those whiskers, don’t they?

Animals use them for sensing things!
动物用它们来感知事物！
Have you ever heard of senses, Squeaks?
你听说过感官，吱吱？
Yes, hearing…

ooh, taste, that’s a good one!
哦，味觉，这是很好的一个感官！
And of course, there’s touch.
当然，还有触觉。
Sensing is how people and animals learn about what’s around them.
感知是人类和动物了解周围事物的方式。
Body parts like our eyes, ears, and fingers let us sense different things.
我们的眼睛、耳朵和手指等身体部位可以让我们感觉到不同的东西。
Let’s think about the cat you were looking at.
让我们想想你刚才看的那只猫。
It uses the whiskers on its face to sense things about its surroundings.
它用脸上的胡须来感觉周围的东西。
Like, how much space is around its face, so it can tell whether it can squeeze through a tight spot!
比如说，它的脸周围有多大的空间，这样它就可以判断它能不能挤过一个紧要关头！
And cats even have whiskers on their front legs.
猫的前腿上甚至长着胡须。
Those work like the whiskers on their face and help them sense when things are close by, especially in the dark!
它们就像它们脸上的胡须一样工作，帮助它们感觉到东西离他们很近，特别是在黑暗中！
Pretty cool, right?
很酷，对吧？
There were other animals with whiskers too.
还有其他有胡须的动物。
See this seal?
看到这个海豹了吗？
Seal whiskers are extra special.
海豹须非常特别。
Well, seals spend a lot of their time in water, where it’s harder for their eyes to see.
嗯，海豹大部分时间都待在水里，在那里它们的眼睛很难看清。
So they have to use other parts of their body to find their way.
所以它们不得不用身体的其他部位来寻找方向。
Like their whiskers!
就像他们的胡须一样！
When fish swim, they make the water around them swirl.
当鱼游泳时，它们会让周围的水打旋。
If a seal is close by, those swirls will reach their whiskers and make the whiskers wiggle!
如果海豹靠近，这些漩涡就会到达它们的胡须，并使胡须摆动！
And those wiggles in the whiskers tell the seal a lot of information.
胡须上的摆动告诉海豹很多信息。
They can tell the seal where the fish went.
他们可以告诉海豹鱼去了哪里。
They can also tell it how far away it is from the fish, and even how big the fish is!
他们还可以告诉它离鱼有多远，甚至鱼有多大！
Well, that information helps the seal catch the fish for its dinner!
嗯，这些信息可以帮助海豹抓到鱼作为晚餐！
It knows whether the fish is just a little snack, or a nice big meal.
它知道鱼是一道小点心，还是一顿丰盛的大餐。
And it knows how far it has to go to catch the fish.
它知道要钓到鱼还需要走多远。
I know!
我知道呀!
It’s really cool.
真的很酷。
And there’s another super neat thing about the seal whiskers.
关于海豹的胡须还有另一件超级棒的事情。
They even work in the cold.
他们甚至在寒冷中工作。
Yes!
是!
If I were to go outside right now, in that cold, wintery weather, my fingertips would get chilly and it would be really hard for me to use my sense of touch, because I couldn’t feel anything very well.
如果我现在出去，在那个寒冷的冬天，我的指尖会变得很冷，我的触觉真的很难使用，因为我感觉不到任何东西。
My fingers can’t feel things very well in the cold!
我的手指在寒冷中感觉不到东西！
It’s okay, Squeaks!
没事的，吱吱！
That’s why we bundle up in warm layers, like gloves and mittens!
这就是为什么我们会裹上保暖的一层，就像手套和连指手套一样！
Scientists thought that seal whiskers wouldn’t work too well in the cold, either!
科学家们也认为海豹胡须在寒冷的天气下也不会起到很好的作用！
Which means that seals swimming in cold water would have a very hard time finding fish.
这意味着在冷水中游泳的海豹将很难找到鱼。
But scientists found out that that’s not actually true!
但是科学家们发现这并不是真的！
Those seal whiskers work just as well in the freezing cold as they do in warm temperatures!
这些海豹胡须在严寒中的效果和在温暖的温度中一样好！
This is super important for the seals, because this way they can find food no matter what temperature the water is that they’re swimming around in!
这对海豹来说是非常重要的，因为这样无论它们游泳的水温是多少，它们都可以找到食物！
I agree.
我同意。
Seal whiskers are amazing, aren’t they?
海豹须很棒，不是吗？
That’s a great question, Squeaks!
这是个很好的问题，吱吱！
What other ways do you think animals can sense things?
