I have never heard of an Bonobo.
Is a sub-species of Chimp. VERY endangered.
I saw a film (from San Diego Zoo perhaps?) some years ago that still makes me laugh when I think about it.
Is feeding time. Handlers throw in some leaf-bearing branches. A largish male grabs one and carries it off to the corner to eat. A female tries to grab some from him, he corrects her, she backs away. So she submissively crawls back, not trying to grab the food, lays down in front of him and spreads her legs. He looks down and immediately has sex with her. The expression on his face is priceless, eyes rolling back and all. They finish quickly and, while he’s sitting enjoying the after-glow, she picks up the branch and walks away.
It was the first example recorded, supposedly, of an animal using sex for other-than procreation.
