The brown spider monkey or variegated spider monkey (Ateles hybridus) is a critically endangered species of spider monkey, a type of New World monkey, from forests in northern Colombia and northwestern Venezuela. Like all spider monkeys, it has very long, spindly limbs and a lengthy prehensile tail which can almost be called a fifth limb. The brown spider monkey has a whitish belly and patch on the forehead, and the eyes are sometimes pale blue. They mainly forage in the canopies of forests and rely mostly on their senses of sight, smell, taste, and touch to find food. Brown spider monkeys are mainly herbivores and frugivores. Taken from "A hand-book to the primates" by Henry O. Forbes, published 1894.
