Baboons live in African woodland savannas, and subsist on roots, tubers, grasses, seeds, and fruit, but also hunt animals smaller than themselves. The three genera of baboons, Mandrillus, Papio, and Theropithecus, are not closely related and differ in morphology and behavior. Papio cynocephalus has a dog-like muzzle and a yellowish-brown coat of fur. Like all baboons, yellow baboons are sexually dimorphic, weighing between 11-26 kg (24-57 lbs), with females approximately 1/2 the size of males. Most times baboons live in polygamous social groups with up to nine females, but they also congregate into foraging 'bands' of 30 individuals, or into 'troops' of as large as 100.
