Golden Lion Tamarin
Photograph by Mark W. Moffett
The critically endangered golden lion tamarin is named for its striking orange mane. Golden lions live primarily in the trees. They sleep in hollows at night and forage by day while traveling from branch to branch. Long fingers help them stay aloft and snare insects, fruit, lizards, and birds.
