Cuttlefish, octopuses, and squid have an almost otherworldly ability to control their appearance.

What makes it possible are these spots.

They're called chromatophores.

They're like tiny water balloons filled with colored pigment.

When the balloons expand, you see more pigment, more color.

When they contract, the color shrinks to a tiny dot.

The overall effect can be really dramatic, and for good reason.

These animals don't have protective external shells.

They're unarmored, naked, and they aren't great swimmers either.

Camouflage is their best defense.

They have to be good at it.

Octopuses can change their body position and the pattern on their skin to match rock or coral.

Octopuses and cuttlefish can even change the texture of their skin to throw off predators, become bumpier and more rock -like.

But squid often live in the open ocean.

How do you blend in when there's nothing except water to blend into?

They do it by changing the way light bounces off their skin.

They can actually adjust how iridescent their skin is using light -reflecting cells called iridophores.

They can mimic the way sunlight filters down from the surface, hide in plain sight.

So how do they control all this color change?

Is it voluntary or some kind of built -in reflex?

That's what researchers at Stanford University wanted to know.

So they anesthetized the squid and then snipped the nerve from the brain that controls the chromatophores, but only on one side of the animal.

The brain essentially couldn't send messages to the tiny muscles that control those chromatophores anymore.

Almost like turning off a light switch.

But after a few days, they noticed something strange.

The chromatophores began blinking again, even though they were no longer getting signals from the brain.

So what does this mean?

Well, what it suggests is that color change might be a bit like breathing is for humans,

something we can either choose to do or do automatically, only even cooler.

Because unlike breathing, color change requires an awareness of your surroundings.

And in these animals, that awareness is spread throughout the skin, as if the skin itself could see.

It would be as if your skin knew what color the walls were, even with your eyes closed.

For a soft and squishy creature trying to stay alive in a very big ocean, it's a pretty spectacular defense.

Thank you.

需要注意的发音

说话人用了 6 次缩略和弱读形式，例如 they're, aren't, couldn't。请按听到的简短形式来说。

“th” 音: breathe /bɹiːð/, anesthetize /əˈnɛs.θə.taɪz/, otherworldly /ˌʌðəɹˈwɜɹl(d)li/
“sh” 和 “zh” 音: essentially /ɪˈsɛnʃəli/, shell /ʃɛl/, cuttlefish /ˈkʌt(ə)lfɪʃ/, camouflage /ˈkæ.məˌflɑːʒ/, squishy /ˈskwɪʃi/
长单词——注意重音位置: essentially /ɪˈsɛnʃəli/, spectacular /spɛkˈtæk.jə.lɚ/, voluntary /ˈvɑ.lənˌt(ɛ)ɹi/, chromatophore /krəˈmætəˌfɔr/, anesthetize /əˈnɛs.θə.taɪz/

中文母语者容易读错的音：

/v/ — 不要读成 /w/，上齿轻触下唇: nerve /nɝv/, protective /pɹəˈtɛk.tɪv/, voluntary /ˈvɑ.lənˌt(ɛ)ɹi/
词尾辅音 — 要读清楚，后面不要加元音: awareness /əˈwɛɹ.nəs/, blend /blɛnd/, dramatic /dɹəˈmætɪk/, reflect /ɹɪˈflɛkt/, expand /ɪkˈspænd/
/r/ 和 /l/ 的区别: reflect /ɹɪˈflɛkt/, voluntary /ˈvɑ.lənˌt(ɛ)ɹi/, coral /ˈkɔɹəl/, otherworldly /ˌʌðəɹˈwɜɹl(d)li/, reflex /ˈɹiːflɛks/

如何用这段视频练习

先完整听一遍视频，不要开口，记下不认识的单词。
用正常速度逐句跟读，每句重复到你的节奏与说话人一致为止。
录下自己的声音并与原声对比，特别注意 awareness, breathe, balloon 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
