NATURE
A Sloth Named Velcro

Air date: Wed., Jan. 25, 8:00 pm

 

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. Once largely ignored, sloths have become a hot topic of scientific researchers. New studies show that they’re not so “sloth-like” after all: despite their reputation, sloths in fact sleep only about as much as humans do and are much more active in the wild than they are in captivity. Other studies have shown sloths are not as solitary as we thought, that they have social structures and that males even keep small harems of females. New research into the gait of sloths has revealed another surprise. X-ray images and photographic analysis show that sloths actually move just like primates, only upside-down.
