Brown-headed Spider Monkey

Ateles fusciceps

Animals of All Regions Back
Brown-headed spider monkeys live in a fission-fusion society of many males and females. Fission-fusion society is a type of social organization in which members of the group break up into smaller groups to forage and then come back together to form their larger group again. For feeding, the large group, consisting of anywhere from 20 to 100 individuals, is temporarily divided into smaller subgroups of about 2 to 4 individuals.

This species spends the majority of its time up in the canopy. Adaptations to this strict arboreal lifestyle include a reduced thumb and a prehensile tail that is used as a fifth limb to swing between branches.


Prefers ripe fruits and leaves, but also eats seeds, nuts and insects
