The acts of cannibalism and infanticide are very apparent in the behavior of the chimpanzee. Many African studies show that wild chimpanzees kill and eat infants of their own species.

Chimpanzees are quadruped, they move on all fours. When walking, they use their knuckles for support with their finger half flexed. This movement is because of the shorter legs and longer arms. They also have opposable toes with good strength of griping.
