Fun facts

Brain size

The brain mass to body mass ratio for squirrel monkeys is 1:17, which gives them the largest brain, proportionately, of all the primates.

Parental Care

Female squirrel monkeys are responsible for almost all infant care. In some squirrel monkey species, males vigorously protect infants from predators. However, with Bolivian squirrel monkeys, males are kept at the edge of the group and do not protect the infants.

Family Life

Bolivian squirrel monkeys are social animals that live in large groups of up to 75 individuals. Females remain in the groups they were born in, while males leave their groups at 4-5 years old to form all-male (bachelor) groups. They then disperse into other family groups when breeding. Adult females are dominant over males and often segregate them to the edge of the group.
