Linnaeus's two-toed sloth (Choloepus didactylus), also known as the southern two-toed sloth or unau, is a species of sloth from South America, found in Venezuela, the Guyanas, Colombia, Ecuador, Peru, and Brazil north of the Amazon River.

It is a solitary, nocturnal and arboreal animal, found in rainforests. It is able to swim, making it possible to cross rivers and creeks. The two-toed sloth's main enemies are man, large birds of prey such as the harpy and crested eagles, and wild cats such as the ocelot and jaguar.

Modern sloths are divided into two families based on the number of toes on their front feet. Linnaeus's two-toed sloth and Hoffmann's two-toed sloth (Choloepus hoffmanni) are larger than the three-toed sloths. They also have longer hair, bigger eyes, and their back and front legs are more equal in length.[4]

Linnaeus's two-toed sloth has recently been documented eating human faeces from open latrines.[5]
