For other uses, see Bonobo (disambiguation). The bonobo (/bÉ.ËnoÊ.boÊ/ or /ËbÉ.nÉ.boÊ/; 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.
Bonobos were previously called pygmy chimps, a misleading name as there is a significant overlap in body size between the two species. Adult female bonobos stand at over 3 feet tall and weigh an average of 68 lbs., while adult males measure up to 4 feet tall and weigh an average of 85 lbs. Perhaps the most interesting difference is the bonoboâs ability to stand up and walk bipedally (on just two feet) more easily and more often than chimpanzees.
