Sloths are one of the most intriguing creatures on the planet. True to their name, these amazing tree-dwellers are so laid back they only answer the call of nature once a week!
There are two-toed and three-toed species of sloths, which is strange, since all sloths have three toes.
Modern day sloths are about the size of a medium-sized dog, but some of their ancestors were much larger. Can you imagine encountering a sloth the size of an elephant?
