About this episode
Sloths are the slowest mammals on Earth. How can a creature that moves so slowly survive in a world that moves so fast? Zoologist Lucy Cooke helps us rethink everything we know about sloths and their slowness. We follow a sloth named Nacho from a rainforest to a nightclub, trek deep into mangrove swamps to find a rare pygmy sloth and uncover the secret that allows sloths to evade even the deadliest predators. Hint: it has to do with a special kind of invisibility. For more, check out Lucy’s A Little Book of Sloth and her sloth calendar ! Terrestrials was created by Lulu Miller with WNYC.
