Choloepus didactylus, commonly known as the two-toed sloth, is a species of sloth found in the tropical forests of South America. It is characterized by its long limbs, a slow-moving lifestyle, and a diet primarily consisting of leaves. Unlike other sloths, it has two toes on its front limbs, which distinguishes it from the three-toed sloth. These sloths are well-adapted to their arboreal habitat, spending most of their time hanging upside down in trees. They have a low metabolic rate, which allows them to conserve energy. Their fur often hosts algae, providing camouflage and a source of nutrients.
