The bonobo also historically 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 being the common chimpanzee (Pan troglodytes). Although bonobos are not a subspecies of chimpanzee (Pan troglodytes), but rather a distinct species in their own right, both species are sometimes referred to collectively using the generalized term chimpanzees, or chimps. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina (composed entirely by the genus Pan) are collectively termed panins.
