The family cebidae is one of the five families of New World monkeys. This family includes 14 species of capuchins and squirrel monkeys. These species are found throughout tropical and subtropical Central and South America. Cebids are arboreal primates spending much of their lives high in the rainforest tree tops. Members of this family are gregarious, living in groups of between five and forty individuals. All cebids are omnivorous, eating fruit and insects, although the proportions of these foods can vary greatly between species.
