On this week’s episode of THE ZOO, viewers met Calisto, a Linnaeus’s two-toed sloth. Hopefully you learned something new about sloths, like that they’re the only mammal whose hair grows in the opposite direction from other mammals. The hair parts in the middle of the belly and grows upward towards the back so water can easily run off them.

Want to test the rest of your sloth knowledge? Take the quick quiz below and see if you can keep up with experts when it comes to sloth science.
