Smithsonian’s National Zoo announces launch of new, action-packed sloth cam. Two-toed sloths are native to Central America and northern South America, including Peru and Brazil. Their brownish-gray fur curves from the stomach to the back, unlike most mammals, allowing rain to run off. The fur is usually home to algae, which help camouflage these rainforest canopy animals. #DropItLikeASloth | Smithsonian’s National Zoo and Conservation Biology Institute
