Emperor Tamarin

Saguinus imperator

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The emperor tamarin is a small primate of the western Amazon, unmistakable for the extremely long white moustache that falls on either side of its mouth. It lives in family groups of between two and eight animals and feeds on fruit, nectar, sap and insects. It frequently forms mixed groups with Weddell's saddle-back tamarin, with which it shares territory, watchfulness and alarm calls: each species is better at detecting a different kind of predator.

Fun facts

  • GeneralIts drooping white moustache gave it its name, because it resembled that of Kaiser Wilhelm II.
  • Its name comes from the German emperor Wilhelm II: the zoologist who described it gave it the epithet imperator half in jest, because its moustache resembled the Kaiser's, and the name ended up becoming official.
  • It forms stable mixed groups with another tamarin species: they travel and feed together and share alarm calls, an interspecific alliance that works because each of them watches a different layer of the forest.
