Each night, small groups of a species called velvety free-tail bats emerge from their roosts in the Panamanian rainforests to hunt for their insect prey, using echolocation.

The first Manx comet, so called after the tailless cats of the Isle of Man, was spotted in 2014 by a telescope in Hawaii.

2014年，人类利用夏威夷的一台望远镜发现了第一颗无尾彗星，并将其以马恩岛上的无尾猫命名，称为“马恩岛猫彗星”。

If one hit Earth it would have an impact velocity of 50-70km per second, about three times that of a nearby asteroid.

如果无尾彗星撞上地球，它的撞击速度将达到每50-70公，大约是地球附近小行星速度的三倍。

We didn't discover the properties of the achoque.

我们没有发现无尾鲀的特性。

You can also see more than a million Mexican free-tailed bats each summer which live in the caves, and I suppose if you want to take a little bat guano as a souvenir, you could do that as well.

每年夏天你还可以看到超过一百万只生活在洞穴中的墨西哥无尾蝙蝠， 我想如果你想带一点蝙蝠粪作为纪念品，你也可以这样做。

But then, around 260 million years ago, decapods split into two groups -- the Anomurans, or those false, fake wanna-be crabs, and the Brachyurans, or the true crabs -- the crabs that aren't lying to you.

但是，大约在 2.6 亿年前，十足类动物分成了两个类群——无尾类动物，或者那些假的、假想成为螃蟹的人，以及短尾类动物， 或者真正的螃蟹——那些没有骗你的螃蟹。

------- Finally, move over, birds -- there’s a new fastest horizontal flyer in town, and it’s a mammal: the Brazilian free-tailed bat.

---------- 最后，走过去，鸟儿——城有一种新的水平飞行速度最快的动物， 它是一种哺乳动物：巴西无尾蝙蝠。

The tailless cat, though some are said to exist in the Isle of Man, is rarer than one thinks.

无尾猫虽然据说存在于马恩岛，但比人们想象的要少。

Right. But when phages are present, they increase production of these tailless capsids.

是的。但是当噬菌体存在时，它们会增加这些无尾衣壳的产量。

But the Brazilian free-tailed bat blows that record out of the water, reaching speeds of 160 kilometers per hour in short bursts during their long nighttime hunting expeditions.

但巴西无尾蝙蝠则完全打破了这一记录，在其长时间的夜间狩猎活动中， 短时间内可达到每小时160公的速度。

Yes, let's delve a bit deeper into the mechanics. CFPICIs can make these tailless capsids on their own.
