Isla Escudo is home to this pygmy sloth, one of four species of three-toed sloths. These folivores (suborder: Folivora), also known as Escudo sloths are not only smaller than mainland species, but they are considerably more docile. They are threatened by the loss of mangrove habitat, and are consumed by local fisherman. The fisherman will camp out on the island and cut down mangroves for fire. They feed on these xenarthrans when fishing is deemed unsuccessful. By the way, the brown-throated three-toed sloth may still be the only publicly displayed three-toed sloth in the US. You can see one at the Dallas World Aquarium and Zoo, Texas. Although sloths are known for their menacing claws I do remember a colleague who was seriously bitten by a two-toed sloth.
