TED-Ed: Why are sloths so slow? - Kenny Coogan

The video explores the history and biology of ground sloths, starting with Jefferson's misidentification of sloth bones as those of a giant lion. It covers the evolution and extinction of these creatures, their ecological roles, and their unique adaptations to a low-energy diet. The video also highlights the survival of smaller sloth species in rainforests and their slow metabolism, which allows them to thrive in treetops. Finally, it discusses how sloths serve as habitats for other organisms.
