Bonobo

Female bonobo.

The bonobo (/bəˈnoʊboʊ/ or /ˈbɒnəboʊ/) (Pan paniscus), formerly called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus Pan; the other is Pan troglodytes, or the common chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the common chimpanzee, whereas Pan paniscus is usually referred to as the bonobo.
