About the Linnaeus's Two-toed Sloth

Linnaeus's two-toed sloth (Choloepus didactylus), also known as the southern two-toed sloth, unau, or Linne's two-toed sloth is a species of sloth from South America, found in Venezuela, Suriname, Guyana, French Guiana, Colombia, Ecuador, Peru, and Brazil north of the Amazon River. There is now evidence suggesting the species' range expands into Bolivia. It's the largest extant sloth species.

Males and females are the same size, growing to lengths of approximately 53 to 89 cm (21 to 35 in), not including the length of the tail, and weigh approximately 4 to 11 kg (9 to 24 lb). Their fur color ranges from a brownish yellow to a pale tone of brown, however, in the wild their fur sometimes has a green hue from algae that grows on their fur during the rainy season. Their belly fur is slightly lighter in color than the body and they have no undercoat. The belly hair is parted along the midline and flows towards the animals back (spine), the opposite direction that fur flows on most other mammals. Young sloths tend to have softer and darker fur than adults.

Sloths belong to the order Pilosa, which also includes anteaters. They belong to the super order Xenarthra... Wikipedia →
