The Emperor Tamarin (Saguinus imperator) is, according to some sources, named after the German emperor Wilhelm II. It was first intended as a joke, because of the resemblance to the German emperor with his big mustache, but since then it is used as a scientific name for this animal. It lives in South America, in Peru, Bolivia and parts of Brazil. They are very light-weighted, so they can reach food at the far end of tree branches, which are unaccessable by heavier animals, including predators. The emperor tamarins display a need for tenderness when kept as a pet. They love to be stroked by hand and will actually lay on their backs in hopes of extra petting attention.
The Emperor tamarin is listed as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category, on the IUCN Red List of Threatened Species
