New World monkeys (except for the howler monkeys of genus Alouatta) [21] also typically lack the trichromatic vision of Old World monkeys. [22] Colour vision in New World primates relies on a single gene on the X-chromosome to produce pigments that absorb medium and long wavelength light, which contrasts with short wavelength light.

Cebid monkeys are arboreal animals that only rarely travel on the ground. They are generally small monkeys, ranging in size up to that of the brown capuchin, with a body length of 33 to 56 cm, and a weight of 2.5 to 3.9 kilograms. They are somewhat variable in form and coloration, but all have the wide, flat, noses typical of New World monkeys.
Like many New World monkeys, bearded sakis are diurnal and arboreal. They inhabit tropical rainforests, usually in the crowns of tree. They move on all four by the branches, spending most of the day searching for food. At the night they sleep clasped to thicker branches, never spending successive nights in the same tree.
