What are the characteristic features of a bonobo?

          As its name suggests, the pygmy chimpanzees is not as big as the common chimpanzee. As is the common feature among all primates, the adult female bonobo is somewhat smaller than the adult male. While the male is about 35 to 60 kilograms, the female is only 30 kilograms. The length of a bonobo from nose to rump when it is on all fours is 70 to 85 cm. However, when standing upright, these animals can reach a height of about 115 cm. The head of a bonobo is relatively smaller than that of the common chimpanzee. This is mainly due to the less prominent ridges it has over its eyes.
