The term 'Arboreal Sleepers' refers to sloths, which are six-limbed mammals that live in trees and sleep for up to 20 hours a day. They are found in the tropical rainforests of Central and South America and are known for their slow movements and low metabolic rate. Sloths are herbivores and feed on leaves, buds, and fruits. They are also nocturnal animals, meaning they are active at night and sleep during the day.
