Why are no elephants the size of amoeba?

为什么没有像阿米巴原虫尺寸的大象？

Some germs are really weird looking, like this one called an 'amoeba'.

有些细菌看起来真的，比如这种叫作“阿米巴”的细菌。

The chance that any virus capable of infecting an amoeba would be able to infect a human is extremely unlikely.

能够感染阿米巴原虫的何病毒能够感染人类的可能性极低。

Anybody with political instincts whatsoever, anybody with an IQ higher than an amoeba would say, no, we shouldn't do that.

何有政治直觉的人，何智商不低于阿米巴原虫的人，都会说：不，我们不该这么做。

I think that Edward Sharpe and the Magnetic Zeros might have been the first album that I...like I went to Amoeba and I specifically selected that album.

Edward Sharpe and the Magnetic Zeros 可能是我的第一张专辑......应该是我去阿米巴的时候了这张专辑。

Though it’s very rare, a snootful of pond water or an improperly cleaned neti pot just might expose you to brain-eating amoebas called Naegleria fowleri.

尽管非常罕见，但鼻子里灌进池塘水或使用清洁不当的净鼻壶可能会让你接触到一种名为福氏耐格里阿米巴的食脑阿米巴。

You might think that they, like snails or clams, build these shells around themselves after they are born, and that is true from some Testate Ameobas.

你可能会认为它们像蜗牛或蛤蜊一样，在出生后会在自己周围建造这些壳，这在某些有壳阿米巴中是正确的。

But it's definitey some kind of Testate Ameoba, which are ameoba that build shells for themselves to live in, and that protect them from predators and, just, the world, which can be a rough place.

但肯定是某种有壳阿米巴，它们是会为自己建造壳来居住的阿米巴，这些壳可以保护它们免受捕食者和其他环境威胁的侵害，因为这个世界有时确实残酷。
