Chimpanzee, often shortened to chimp, is the common name for the two extant species in the genus Pan.
The better known chimpanzee is Pan troglodytes, the Common Chimpanzee, living primarily in West, and Central Africa.
Its cousin, the Bonobo or "Pygmy Chimpanzee" as it is known archaically, Pan paniscus, is found in the forests of the Democratic Republic of the Congo.
The Congo River forms the boundary between the two species.
Chimpanzees rarely live past the age of 40 in the wild, but have been known to reach the age of 60 in captivity, and Tarzan star Cheeta is still alive as of 2006 at the age of 74.
