The bonobo, "Pan paniscus", is a great ape and the smaller of the two species making up the genus "Pan" (the other is "Pan troglodytes", the common chimpanzee). The bonobo is sometimes called the dwarf or pygmy chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood to mean the common chimpanzee, while "Pan paniscus" is usually referred to as the bonobo.
