One adult male is dominant, although in larger groups dominance can be shared among several males. These groups can include 15-150 individuals but a few dozen is typical, with at least two levels of social units. Social BehaviorĬhimpanzees are highly intelligent and live in complex social groups. At the Zoo, the chimps are fed a variety of foods, such as fruits, vegetables and monkey chow. Chimps will also regularly work together to hunt other primates and small animals. The chimpanzee range includes equatorial forests of west and central Africa in rainforests, deciduous forests and savanna woodlands.Īs omnivores, they feed on a variety of fruit, leaves, seeds, bark, honey, insects and eggs. Lifespan in the wild is about 50 years, and up to 60 years under human care. Chimps have opposable thumbs used for climbing, using tools, grooming, and grasping food. Chimpanzees are capable of walking on their hind legs as well, but only with the toes turned inward. Long and muscular arms allow them to move easily through trees but most locomotion is done on all fours by knuckle-walking. Males weigh from 126-176 pounds, while females weigh from 100-150 pounds. Baldness is common and more extensive in females. The hair of these tree-dwelling animals is long and coarse, usually dark brown or black. Chimpanzees, and their cousins the bonobos, are more closely related genetically to us – sharing 98.4% of our DNA – than they are to gorillas!. They will also create leaf “sponges” for getting water out of tree-boles and crevices.
