At the Sloth Sanctuary we have two types of sloths: Bradypus variegatus (Three-fingered sloth) and Choloepus hoffmanni (Two-fingered sloth). Below is a table of where the sloth fits into the order Xenartha. Xenarthans are mammals with unique joints in their backbone, have few or no teeth and a small brain. Armadillos, anteaters are in the same super-order as the sloth.
