Though their ancestors lived in North America, modern sloths live in Central and South America, enjoying the tall trees found in rain and cloud forests. Sloths prefer sleeping while curled into a ball in the fork of a tropical tree. They also like to sleep hanging by their claws from tree branches.
For the most part, a sloth's life revolves around sleeping and eating in their tree homes. The only times these mammals leave their tree is to use the bathroom and to take a swim.
Sloths in captivity sleep from 15 to 20 hours per day, which can leave them very little time for social activities. Sloths in the wild, though, sleep about as much as humans, according to research by the Planck Institute for Ornithology in Starnberg, Germany.
After around nine hours of sleep, the sloth still doesn't make an attempt at getting friendly with others. They live solo lives. The closest a sloth gets to social time is sleeping in the same tree with another sloth.
