primates have a longer juvenile period between weaning and sexual maturity than other mammals of similar size. some primates such as galagos and new world monkeys use tree-holes for nesting, and park juveniles in leafy patches while foraging. other primates follow a strategy of "riding", i.e. carrying individuals on the body while feeding. adults may construct or use nesting sites, sometimes accompanied by juveniles, for the purpose of resting, a behavior which has developed secondarily in the great apes. during the juvenile period, primates are more susceptible than adults to predation and starvation; they gain experience in feeding and avoiding predators during this time. they learn social and fighting skills, often through playing. primates, especially females, have longer lifespans than other similarly sized mammals, this may be partially due to their slower metabolisms. late in life, female catarrhine primates appear to undergo a cessation of reproductive function known as menopause; other groups are less studied.
