This monkey is primarily from the Central and South American jungles. It is also called the owl monkey due to the largeness of the eyes which allows for a greater amount of light to enter. They are nocturnal and have no color vision, but have excellent low level and night vision which enables them to catch insects and move in darkened conditions with greater ease then other types of primates. The more scientific name for the owl monkey is the douroucoulis. The female and male monkeys weigh very close to the same, with males weighing just a bit more, at 2.76 pounds.
The family unit is composed of pairs
