Sloth

There are six extant species of medium-sized mammals belonging to the families Megalonychidae (two-toed sloth) and Bradypodidae (three-toed sloth), part of the order Pilosa. They are arboreal residents of the rainforests of Central and South America. Ground sloths are a diverse group of extinct sloths, it does not imply that all extinct sloths were strictly terrestrial in nature. The bulk of ground sloth evolution took place during the mid to late Tertiary of South America while the continent was isolated.
