The Emperor Tamarin (Saguinus imperator) is a tamarin allegedly named for its similarity with the German emperor Wilhelm II. The name was first intended as a joke, but the name has become the official scientific name.
This tamarin lives in the southwest Amazon Basin, in east Peru, north Bolivia and in the west Brazilian states of Acre and Amazons.
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. Its long, white mustache extends to both sides beyond the shoulders. The animal reaches a length of 9.45 to 10.24 in (24 to 26 cm), plus a 13.78 in (35 cm) long tail. It weighs approximately 10.58 to 14.11 oz (300 to 400 g).
This primate inhabits tropical rain forests. It lives deep in the forest and also in open tree-covered areas. It is a diurnal animal, spending the majority of its days in the trees. It goes through the trees with quick, safe movements and broad jumps among the limbs.
The Emperor Tamarin lives together in groups of two to eight animals. The oldest female leads the group above several mature males. The mutual grooming plays an important role for bonding and socializing. The animals often associate themselves with other tamarins like the brown-mantled tamarin. It has various cries that help them to promptly recognize interlopers.
The diet of the Emperor Tamarin is similar to that of other tamarins. It is an omnivore, primarily eating fruits, insects and sap. It also eats bird eggs and small vertebrates (such as tree frogs). Due to its small weight it can reach food at the far end of branches that are not accessible to heavier animals.
