These guys spend almost their entire lives in the canopy. And their nickname is the “messenger of the gods,” as climb really high and face the sun at dawn and dusk.
Black and White Colobus Monkey

Oh tiny little little smallest monkey. Here are some facts:
Ah. The gentleman Guinea Baboon. “Why are they gentlemen?” you ask. Let me tell you…
The Guinea Baboon, unlike most of its primate relatives, doesn’t live in a tree swinging around, playing, joking, and throwing poo. No. The Guinea Baboon does all that from the ground. They are very civilized that way. They are very well spoken and courteous mammals. With just a mere look, they can express that you’ve disturbed, offended, or threatened them in a way that they do not appreciate. If you find yourself on the other end of this look, be ready to get slapped.
