　　And there he is, his droopy little eyes up here. But they can do pretty amazing things, too.  看它，看它那双无精打采的眼睛。不过它们能做很神奇的事。

　　Here we're going to see one backing into a crevice,  我们马上就能看到它退入到礁石的夹缝中去，

　　and watch his tentacles² -- he just pulls them in, makes them look just like algae³. Disappears right into the background.  注意它的触角，它就这样把触角拉进来，使自己看起来像海藻一样。刹那就消失在背景中。

　　Positively⁴ amazing. Here's two males fighting.  多神奇！这又是两只雄性在搏斗。

　　Once again, they're smart enough, these cephalopods; they know not to hurt each other.  当然，这些头足类非常聪明，他们知道如何不会伤害到对方。

　　But look at the patterns that they can do with their skin. That's an amazing thing. 不过看下它们能够利用皮肤来变换图案。怎么样？很神奇吧！

　　Here's an octopus⁵. Sometimes they don't want to be seen when they move, because predators⁶ can see them.  这是个章鱼。有时候，它们不想被别人发现它们在移动，因为那些食肉动物会发现它们。

　　This guy can make himself look like a rock, and, looking at his environment,  看，这个家伙把自己弄的像石头一样，观察着它周围的环境，

　　can actually slide across the bottom, using the waves and the shadows so he can't be seen.  然后滑过水底，利用波纹和阴影来隐藏自己，从而不被发现。

　　His motion blends right into the background -- the moving rock trick. 就是这样，无声无息地融入环境之中。这就是移动石头的手法。
