Nature - Season 33 Episode 5 -

Sloths, once largely ignored, have become a hot topic of scientific researchers. Sanctuaries and rehabilitation centers are also springing up, as development often displaces these gentle creatures. Filmed in Panama, Costa Rica and Colombia, this is a story of friendship between a journalist and the sloth she named Velcro and a network of people working to learn more about sloths in order to protect them.
