Zoological name: There are two species- the common chimpanzee
(Pan troglodytes) and the pygmy chimpanzee (P. paniscus).
Distribution: Chimpanzees are found in Central and West Africa.
Habitat: They inhabit in grass lands, woodlands and rain forests.
Reproduction: Chimpanzees attain maturity at 7-10 years of age. The wild females, however, mature a few years later. There is no particular breeding season. The oestrus cycle is recorded 25-37 days. The skin of the perineum and the posterior portions of buttocks swell to a large size during estrus like baboons and rhesus monkeys. The female may be served by half a dozen males. She gives birth to a young (rarely twins) after a gestation period of 230-285 days. The young remain with the mother for at least 5-7 years.
