The squirrel monkey has short fur, coloured olive on the squirrel monkeys shoulders and yellowish orange on the squirrel monkeys back. The squirrel monkeys throat and ears are white and the squirrel monkeys mouths are black. The upper part of the squirrel monkeys head is quite hairy when compared to the rest of the squirrel monkeys body.
The squirrel monkeys have a number of vocal calls which the squirrel monkeys use to communicate with other squirrel monkeys. These squirrel monkey sounds include warning sounds to protect themselves from large falcons, which are a natural threat to the squirrel monkey. The squirrel monkeys small body size also makes the squirrel monkey easy prey for predators such as snakes.
The squirrel monkey is an omnivore meaning that the squirrel monkey primarily eats fruits and insects. Occasionally the squirrel monkey will also eat nuts, buds, eggs and small vertebrates that the squirrel monkey finds in the surrounding tree branches.
