two-toed sloth

Choloepus is a genus of mammals of Central and South America, within the family Megalonychidae consisting of two-toed sloths. The two species of Choloepus (which means "lame foot"), Linnaeus's two-toed sloth (Choloepus didactylus) and Hoffmann's two-toed sloth (Choloepus hoffmanni), are the only surviving members of the family Megalonychidae.
