The chimpanzee is the third largest ape after the gorilla and the orangutan. A male stands about 1.5m tall when upright and weighs about 43 kg. It has a pink to brown face and thick, long, brown-black hair. The face, ears, hands and feet are hairless. Like other great apes, chimps are tailless.
Chimpanzees have longer arms than legs.
They can move on the ground or through trees. On the ground, they run on all fours, but walk upright with toes turned inwards. While on all fours, they support the weight of their body on the knuckles of their hands. Chimps are scared of falling from trees and rarely swing by their arms as gibbons and orangutans do. Chimpanzees are mainly vegetarians, eating leaves, roots, and fruits like wild figs.
