🦥 Happy International Sloth Day!
Today, we're hanging out with two of our three sloths here at Zoo Knoxville! Meet Cosmo and Wanda, our Hoffmann's two-toed sloths!
These slow-moving mammals are native to the tropical forests of Central and South America, where they spend nearly their entire lives in the trees. Sloths are arboreal, meaning they're specially adapted for life in the treetops. Their long, curved claws allow them to hang upside down while eating, resting and even sleeping!
In the wild, Hoffmann's two-toed sloths enjoy a diet of leaves, fruits, flowers and tender shoots. They can spend up to 15 hours a day sleeping or resting, often while hanging upside down!
Hoffmann's two-toed sloths are currently listed as Least Concern in the wild, but habitat loss and deforestation continue to threaten the forests they call home.
While Cosmo and Wanda currently live behind the scenes, you can visit our third sloth, 7-year-old Joe, at the ARC! Be sure to look up when you visit. You might just spot Joe climbing around above your head! 🌿
