Chimpanzees live in a variety of African habitats, and consume both vegetation and meat. Part of the family of great apes, the four recognized subspecies of chimpanzees are Pan versus, P. paniscus, and P. schweinfurthii, and P. troglodytes, or the common chimpanzee. Characterized by large ears, chimpanzees also have a prognathic (protruding) face with large lips and pronounced supraorbital crests. Their weight ranges between 34-70 kg (75-154 lbs) for males, and 25-50 kg (55-110 lbs) for females, with higher weights observed in captivity. Chimpanzees are known for manufacturing and using tools, something once considered an exclusively human trait.
