Saki Monkeys are smaller monkeys with long, bushy tails. Their furry, rough skin is black, grey or reddish-brown colored depending upon the species. The faces of some species are naked, however, their head is hooded with fur. Their bodies are adapted to life in the trees, with strong hind legs allowing them to make far jumps. Saki Monkeys reach a length of 30 to 50 centimetres, with a tail just as long and weigh up to 2 kilograms.

The Sakis Monkeys range includes northern and central South America, extending from the south of Colombia over Peru in northern Bolivia and into the central part of Brazil.
