Learn all about slow-moving sloths, mammals of the Central and South American rainforest. Detailed graphics, diagrams and video images help us learn about two types of sloths, extinct sloths, lifespan, how and when they sleep, their eating habits, digestive process, why and how they sleep in trees, why their fur is greenish in colour, sloths on the rainforest floor, and the story of a rescued sloth. Multiple-choice reviews at the end of each segment reinforce important concepts.
