The two-toed sloth does everything while hanging upside down from trees, including eating, sleeping, mating and even giving birth!
Sloths move very slowly and sleep for up to 15 hours a day to conserve their energy. This is mostly down to their diet, which is made up of low-energy food like leaves and fruit.
If you spend a lot of time hanging in trees then you need to be able to hold tight, and the sloths have a very powerful grip. Their long claws curve around tree branches like a safety harness.
Despite this powerful grip, sloths actually have a relatively low muscle mass of around 25% - mammals usually have around twice as much.
You can spot our slow sloths inside Spirit of the Jaguar where you can find them clinging on to trees or exploring their aerial habitat right above your heads!
Our two-toed sloth, named Tina, arrived in 2012 after moving from a zoo in Germany where she was born in 2011.
