indri are a kind of lemur
The biggest surviving species, actually. There used to be bigger, slower ones, the size of small cows, but you know what happens to big, slow, small-cow-sized things with no natural predators when humans finally make their appearance. Indri are black and white, and weigh about thirty pounds apiece. They are the only lemur species that can't be bred in captivity, and also the only ones without tails.
Anyway. Here's another sort of lemur of which I am now enamored. Check them out.
