So the clasper will go in the female.

所以扣子会性。

The sharks have these long spines, spurs in their claspers but other animals like snakes for example they also have spines.

鲨鱼有这些长刺，在它们的扣环中有刺，但其他动，例如蛇，它们也有刺。

And then, once the male is inside of the female He will actually pull down on a muscle and essentially open up the tip of the clasper.

然后，一旦雄性雌性体内，他实际上会拉下肌肉并基本上打开扣环的尖端。

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 很可能是从这里的泄殖腔口来的，它可能正穿过这里的这个小凹口。

Essentially there's very little consideration given to: " Well where's this clasper actually going and what is it doing? " And so that surprised me, again in a good way because it means that I have an interesting question to go look at.

基本上很少有人考虑：“嗯，这个 clasper 到底要去哪里，它在做什么？”所以这让我感到惊讶，再次以一种好的方式，因为这意味着我有一个有趣的问题需要研究。
