There are two types of sloths,two-toed and three toed. However this can get confusing as both type have three claws or 'toes', on their hind limbs.In reality, the ‘two-toed’ sloth should really be called the ‘two-fingered’ sloth as the difference between them both can be found on their front limbs.

The modern sloth is usually around the size of a medium-sized dog. But ancient sloths of years ago, known as ‘Megatherium’, could grow as large as an Asian elephant! These giant sloths sometimes featured areas of small bone discs that would act as ‘armour plating’ for protection. They became extinct around 10,000 years ago.

Sloths possess a symbiotic relationship with the algae that grows on their fur. While the sloth provides the algae with shelter and water (as sloth fur is highly absorbent), the algae provide the sloth with camouflage as well as extra nutrients through their skin.
