Procolobus
Extracted from the Wikipedia article Olive colobus.
Description
Procolobus verus is a small-bodied mammal with an average body weight of 4.6 kilograms for males and 4.1 kilograms for females. The olive colobus are greenish-brown in color with the hairs transitioning from greenish-yellow at the root, and becoming darker towards the tip. The under side of the olive colobus is lighter in color and the hairs found on the face are stiff and dark. Their coloration allows them to stay camouflaged within the trees reducing the risk of predation. Like all colobine monkeys, olive colobuses have a unique feature in that in their hands, their thumbs are severely reduced, while their feet retain fully functional big toes. The feet of the olive colobus are also abnormally large compared to other African colobine species.
