Are humans the only 動物 where the girl can top?

Now I'm not going to claim this as the truth because I honestly have no clue but my theory is that it's easier on four legged 動物 that way just because of the way their bodies are structured. So maybe 動物 like gorillas and monkeys can have females topping to.

Idk what I'm talking about though so ignore me.

I've never seen female 動物 topping. I think primarily because missionary and doggystyle makes it easier for the sperm to find the egg generally. People have 発言しました that in referenced to human sex so ya as far I am aware of we are the only 動物 that it is optional for the female to top.
