Both types of extant tree sloth tend to occupy the same forests; in most areas, a particular species of the somewhat smaller and generally slower-moving three-toed sloth (Bradypus) and a single species of the two-toed type will jointly predominate.
A total of five species of sloths exist: the pygmy three-toed sloth, the maned sloth, the pale-throated three-toed sloth, the brown-throated three-toed sloth, and Linnaeus’s two-toed sloth. All sloths are either two-toed or three-toed.

The oldest known sloth in the world was a two-fingered sloth named Jan, who was 54 years old and lived at a zoo in Germany. We suspect that wild sloths actually live for much longer than that, and we're determined to study sloth logevity with an upcoming research project called 'The Eternal Sloths'!
The sloth has been called nature's mistake, named after a deadly sin, and dismissed by scientists for centuries. They were all wrong.
The pale-throated three-toed sloth is found in northern parts of South America (typically north of the Amazon River and east of the Andes), while the maned three-toed sloth is restricted to the Atlantic Forest of southeastern Brazil.
