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.
The bonobo is commonly considered to be more gracile than the common chimpanzee. Although large male chimpanzees can exceed any bonobo in bulk and weight, the two species actually broadly overlap in body size.Adult female bonobos are somewhat smaller than adult males. Body mass in males ranges from 34 to 60 kg (75 to 132 lb), against an average of 30 kg (66 lb) in females.he total length of bonobos (from the nose to the rump while on all fours) is 70 to 83 cm (28 to 33 in). When adult bonobos and chimpanzees stand up on their legs, they can both attain a height of 115 cm (45 in).
