What is a sloth?
Sloths are the stars of memes and viral videos. They make us laugh, and they make celebrities cry. But these social media darlings have been around far longer than the internet. Millions of years ago, giant ground sloths the size of elephants roamed the planet. Some were nearly 20 feet long from snout to tail, with massive claws for pulling tree branches down to eat.
Today’s sloths are a little less intimidating. They max out at about 2.5 feet and weigh between 9 and 17 pounds (about the size of a small dog). They have coarse, brown fur, long limbs and curved claws for hanging tightly onto tree branches — the adaptation to upside-down tree living. And they’re one of the slowest-moving animals on earth!
