Kenny Coogan: Why are sloths so slow? (2017x47)

Data di messa in onda: Apr 25, 2017

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. [Directed by Anton Bogaty, narrated by Addison Anderson].
