Sloth

Sloth, any individual of the Edentate family Bradypodidae, with two genera (Bradypus and Choloepus) from Central and South Amenca. In the first genus, to the species of which the name "Ai" is often applied from their cry, there are but two functional digits on the fore-limbs; in the second there are three. They are vegetable feeders and arboreal in habit, and move along the branches of trees, with the body downwards. The body is covered with long, coarse hair, which is often covered with a growth of green algae. The largest of the family is about 30 inches long.
