Squirrel monkeys are one of few species of New World monkeys that do not have prehensile tails. Instead, they use their hands and feet to move deftly through the middle canopy, while their tails are used mainly for balance.
Squirrel monkeys prefer to eat fruit and insects. Thanks to their small, agile bodies they are able to easily climb to the ends of branches to retrieve fruit. Occasionally these monkeys will also dine on leaves, seeds, arthropods and some small vertebrates.
A typical squirrel monkey has short, olive-colored fur covering its body, except for a bright yellow back and appendages, a white face and ears, and a black muzzle. They do not exhibit much sexual dimorphism, meaning the males and females tend to look very similar. Their slender bodies grow to be about 30 centimeters long, while their tails can be closer to 40 centimeters. Females weigh between 500 and 750 grams, whereas males tend to weigh about one kilogram.
