Brown-throated three-toed sloth in Manuel Antonio National Park, Costa Rica

Feeling lazy? Today's your day

If you're moving slow today, that's just fine: You're outpacing today's homepage subject, which spends 90% of its time scarcely moving a muscle.

We’re hanging out with this famously unhurried rainforest dweller for International Sloth Day. Sloths like this three-toed specimen move very little to conserve the scant energy gained from their leaves-only diet. They live their whole lives hanging around in trees from their hooked claws, only descending for toilet breaks and an occasional swim. Sloths even sleep in a dangling position, often snoozing away 20 hours of the day. Jealous?
