Squirrel monkeys are found in most of South America and in Central America (just Costa Rica and Panama). Capuchins are found in most of South America and Central America and the Caribbean islands of Trinidad and Tobago.

Cebids are found in the spreading forest canopy and in smaller understory trees. Squirrel monkeys also inhabit swamps, while capuchins thrive in dry forests.

Squirrel monkeys eat predominantly fruits and insects, but also feed on flowers, shoots, buds, leaves, spiders, frogs, bats, and crabs. Capuchins consume mainly fruits, but also eat insects, snails, lizards, small birds, baby squirrels, crabs, and oysters.



Cebids are popular as pets and zoo exhibit animals. They are used in medical research. They have been used in the space program to test the effects of space travel. Capuchins are trained to help disabled persons, using their human-like hands to perform daily tasks, such as feeding people.

IUCN lists the yellow-breasted capuchin as Critically Endangered, facing an extremely high risk of extinction, because of habitat loss and degradation, and hunting for food. It classifies the red-backed squirrel monkey as Endangered, facing a very high risk of extinction, and the black squirrel monkey and the crested capuchin as Vulnerable, facing a high risk of extinction, due to habitat loss and degradation.
