Document Summary
Siamangs s e n i h r r i s p e r t. Human hunting and destruction of habitat led to extinction of larger lemur species. Eat only animal food such as insects, birds, bats and snakes. They have a tiny body and enormous eyes and feet. Similar to human placenta, heavier infants, exhibit postorbital partition. Dry nose, similar to humans separate from lip catarrhines. Reach sexual maturity by 3 years, gestation is 6 months and they give birth to a single offspring. Ritualized policing of behaviour in baboons as well as nurturing by group. Macaques have complex social structure, adapt to habitat change well. Tailless, long coats varying from cream to brown to black. Gibbons are monogamous, live in family groups of a mated pair and offspring. Establishing territory is difficult for new pairs, evidence shows parents help. Unflanged males are same size as females, flanged males (grow fleshy jowls) are twice as large.
