Chimpanzees can reach up to 4 feet in height and weigh as much as 175 pounds, with males being larger than females. The great apes' coats are largely black, although they can vary greatly among individuals, with some having more reddish-brown fur. Each face is unique, as in humans, with different colors, hairlines and amounts of facial hair. Young individuals have a tuft of white hair on their rump that signifies their immature status.
