Brown-throated Sloth

The Brown-throated Sloth (Bradypus variegatus) is the most common of the four species of the three-toed Sloth and is found in the forests of South and Central America.
Brown-throated Sloths sleep 15 to 18 hours every day and are active for only brief periods of time, which may be during either the day or night. Although they can walk along the ground, and even swim, they spend most of their lives in the high branches of trees, descending once every eight days or so to defecate in the soil.
