Squirrel monkeys live in large, mixed groups of numerous males and females and feed primarily on fruits and insects.
Danger
The distribution area of this species is in a protected area in which hunting is prohibited, but forest clearing does occur. Due to its small habitat, the IUCN lists the species as endangered ( vulnerable ).
