In Sloths, Masters of Slow and Steady, evolutionary biologist Ben Garrod describes how a sloth's skin provides unique camouflage, helping it blend into its environment for protection. Discover the symbiotic relationship between sloths and algae, which grows on their fur and gives them a greenish tint. This algae offers camouflage while also supporting moths that help fertilize the algae. Through this fascinating example of nature’s design, see how animals and plants can depend on each other in unexpected ways. This video is excerpted from Secrets of Skin, a documentary series exploring the natural history of the body’s largest organ.


In The Pygmy Sloth's Search for a Mate, narrator Sir David Attenborough explains the unique challenges faced by pygmy sloths on Escudo de Veraguas Island.

This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
