Sloths spend most of their time eating, resting, or sleeping; in fact, they descend from their treetops canopies just once a week, for a bathroom break. How are these creatures so low energy? Kenny Coogan describes the physical and behavioral adaptations that allow sloths to be so slow.

Lesson by Kenny Coogan, animation by Anton Bogaty.
