Choloepus is a genus of xenarthran mammals from Central and South America within the monotypic family Choloepodidae, consisting of two-toed sloths,[3] sometimes also called two-fingered sloths.[4] The two species of Choloepus (which means "lame foot"[5]), Linnaeus's two-toed sloth (Choloepus didactylus) and Hoffmann's two-toed sloth (Choloepus hoffmanni), were formerly believed on the basis of morphological studies to be the only surviving members of the sloth family Megalonychidae,[6] but have now been shown by molecular results to be closest to extinct ground sloths of the family Mylodontidae.[4][3]
