The Emperor Tamarins (Saguinus imperator) inhibit tropical rain forests and open tree covered areas of the southwest Amazon Basin, east Peru, west Brazilian states of Acre and Amazonas, and north Bolivia. Originally, the word "Tamarin" was allegedly named for their long, white moustache that resembles the German emperor Wilhelm II, and their moustache can extend to both sides beyond their shoulders. There are yellowish speckles around their chests and their furs are generally grey in color. Their adults can reach a weight up to 300 to 400g. As they are omnivorous animals, they feed on bird eggs, small vertebrates such as tree frogs, fruits, sap and insects. While feeding on sap, they latch on to the tree vertically with their claws dug into the bark of the tree. They spend most of their time swinging and jumping through the forests with their active limbs.
