They use their ultra black to get noticed.

他们用他们的超黑色来引起注意。

Unlike deep-sea fish, these birds aren't ultra black for camouflage.

与深海鱼不同，这些鸟不是为了伪装而显得超黑的。

So to be considered ultra black, you have to reflect less than 0.5% of the light that hits you.

所以要被认定为超黑，你必须反射不到 0.5% 的光线。

Other animals like butterflies, spiders, even snakes, make ultra blacks using similar pigments or structures as these fish and birds.

其他动物，如蝴蝶、蜘蛛，甚至蛇，使用与这些鱼和鸟相似的色素或结构制造超黑色。

So to stay unseen, these ultra black fish have evolved an extreme way to absorb almost every last bit of stray light that hits them.

所以为了不被发现，这些超黑鱼已经进化出一种极端的方式来吸收几乎每一点击中它们的杂散光。

Because of ultra black materials, we've been able able to take pictures of the universe like never before, harness energy, even make our own camouflage.

因为有了超黑色材料，我们能够以前所未有的方式拍摄宇宙，利用能量，甚至制造我们自己的伪装。

But you may be surprised to learn that evolution figured out this way of using nanotech to make ultra black more than 100 million years before we did.

但是你可能会惊讶地发现进化比我们早 1 亿年就找到了利用纳米技术制造超黑色的方法。

In 2014, scientists realized that tiny forests of carbon nano tubes can be used to make ultra black materials Unlike pigments, which absorb light, these nanotubes trap light in sort of molecular cages.

2014 年，科学家们意识到碳纳米管的微小束可以用来制造超黑色材料。与吸收光的颜料不同，这些纳米管将光捕获在分子笼中。

Well, ultra black materials have a bunch of uses, from lining the inside of telescopes to help us see the light from distant stars, to making better solar panels, to radar-tricking camouflage.

嗯，超黑色材料有很多用途，从望远镜内部的衬里来帮助我们看到来自遥远恒星的光，到制造更好的太阳能电池板，再到雷达欺骗伪装。
