Saguinus imperator

The emperor tamarin (Saguinus imperator), is a species of tamarin allegedly named for its resemblance to the German emperor Wilhelm II. It lives in the southwest Amazon Basin, in east Peru, north Bolivia and in the west Brazilian states of Acre and Amazonas. The fur of the emperor tamarin is predominantly grey colored, with yellowish speckles on its chest. The hands and feet are black and the tail is brown. Outstanding is its long, white beard, which extends to both sides beyond the shoulders. The animal reaches a length of 23–26 centimetres (9–10 in), plus a 35–41.5 cm (13.8–16.3 in) long tail. It weighs approximately 500 grams (18 oz). There are two subspecies of the emperor tamarin: The Saguinus imperator belongs to the family Callitrichidae, which is a family of New World monkeys. The Callitrichidae contains the two general species of marmosets and tamarins. There are several different Saguinus groups within the Callitrichinae subfamily, including S. midas, S. mystax, S. nigricollis, S. bicolor, S. oedipus, and S. inustus. Saguinus imperator belongs to the S. mystax group. The emperor tamarin has two subspecies: Saguinus imperator imperator and Saguinus imperator subgrisescens. The predominant difference between the two is that Saguinus imerator subgrisecens has a long white beard, giving it its customary name the “bearded emperor tamarin.” (Saguinus imperator imperator) Black-chinned emperor tamarin
