Who can't relate to sloths? They love warm climates, they can spend a whole day just chilling, and are very cute. But there's a lot of wild things you might not know about these fascinating animals.

Here are eight weird facts about everyone's favorite tree-dwelling mammal.

Most sloths eat a regimen of toxic leaves that provide little energy and can take up to a month to properly digest – in fact, if they digested any faster, the toxicity would poison them.

So sloths need to rest to do all that digestive work.

They’ve been known to spend 60 percent of their day just sitting around digesting. And you thought you were lazy after Thanksgiving dinner.

Sloth are great swimmers. Their strong arms are made for holding onto branches, but are also well-suited for swimming. They can swim three times faster than they can walk on land.

Plus their ability to slow their heart rate down means sloths can hold their breath for up to 40 minutes underwater.

Sloths are creatures of habit. They poop once a week and usually in the same spot.

Their slow metabolism means they can go for long stretches between... movements... and they have to climb down to the forest floor to do so.

Because their weak hind legs make movement on the ground slow-going, that’s where they’re most vulnerable to predators. No wonder they hold it.
