And to finish the act, the male kisses his cloaca to hers and ... GEORGE HUNT: And fertilizes her.

为了完成这个作，雄性将他泄殖腔亲吻到她泄殖腔，然后… … 乔治·亨特：并让她受精。

Today I—I talked to a researcher who studies Greenland sharks, but I was more interested  in the parasitic barnacle inside the cloaca.

今天我和一位格陵兰鲨鱼人员交谈过，但我对泄殖腔内寄藤壶更感兴趣。

Then, much like a reptile or bird, she lays eggs from her cloaca, a single opening that's used for both reproduction and excretion.

然后，就像爬或鸟类一样，她从泄殖腔产卵，泄殖腔是一个用于繁殖和排泄开口。

This involves sucking air into their cloaca— a hole used for urinating, defecating and reproduction— and then shooting it back out with a loud pop.

这涉及将空气吸入它们泄殖腔——一个用于排尿、排便和繁殖孔——然后用一声巨响将其射出。

So that clasper most likely is coming in from the entrance here of the cloaca and it's probably going right through this little notch right here.

所以那个 clasper 很可能是从这里泄殖腔入口进来，它可能正穿过这里这个小凹口。

Reptiles, amphibians, most birds, and monotremes like the platypus have a cloaca, a multipurpose swiss army knife of holes, linking the urinary, waste, and reproductive systems… I guess you could say: one ring to rule them all.

爬、两栖、大多数鸟类和像鸭嘴兽这样单孔类都有泄殖腔，这是一把多用途瑞士军刀，连接着泌尿系统、废系统和殖系统… … 我想你可以说：一环统领它们。
