Red Handed Tamarin

The red-handed tamarin (Saguinus midas), also known as the golden-handed tamarin or Midas tamarin, is a New World monkey named for the contrasting reddish-orange hair on their feet and hands. It is native to wooded areas north of the Amazon River in Brazil, Guyana, French Guiana, Suriname, and possibly Venezuela. The population south of the Amazon River lacks the contrasting feet and hands, and is now commonly treated as a separate species, the Black Tamarin.
