It looks like a classic gorilla mask, as far as the face goes - it doesn't look like a real ape, but like a mask from a "gorilla suit" that you see in spoofs of horror films, etc.

Not that I think we have discovered every species that exists on this planet, but from the photo, that doesn't even look like a GOOD fake. The face shows all nice even, uniform white teeth, for goodness sake - when's the last time you saw a wild critter that looked like it had had orthodonture done?
