Which one is REALLY true about the Sloth?

The short version

ages 9–12

Instead of going safely in the treetops, a sloth climbs all the way down to the ground where predators wait, does a wiggle scientists call the 'poop dance', and can lose a third of its body weight in one go.

Why it's so weird

  • The Sloth only poops about once a week.
  • The Sloth climbs all the way down to the ground to poop, right where wait.
  • The Sloth does a slow wiggle scientists actually call the 'poop dance'.
  • The Sloth can lose up to a third of its body weight in a single bathroom trip.

The full story

Sloths only poop once a week, and every single time they do it, they literally risk their lives. Here is why. Sloths are incredibly slow and basically defenseless, so being high up in the trees is by far the safest place for them to be. But for some strange reason, when it is finally time to go, they refuse to just go from up there. Instead, the sloth slowly climbs all the way down to the base of the tree, which is exactly where predators like jaguars and snakes are waiting. Then it digs a little hole and does a slow wiggle that scientists actually call the poop dance. And in one single go, a sloth can lose up to a third of its entire body weight. A weekly bathroom trip that could genuinely get it killed. Follow for more weird animals.

🔬 The science — how & why

A sloth eats only tough leaves that give very little energy, so its whole body runs in slow motion to save fuel. Digesting one leafy meal can take weeks, so waste builds up slowly until a big pouch in its gut is full, which is why it only goes about once a week. Why it then risks the dangerous climb to the ground instead of dropping waste from the trees is still debated: some scientists think the poop feeds tiny moths and algae that live in its fur, while others think the buried waste leaves a smell message to help sloths find a mate.

🔎 How do we know?

Sloth biologist Rebecca Cliffe and her team weighed wild three-toed sloths before and after they used their forest-floor toilet and watched their stomachs visibly shrink, recording losses of up to about a third of body weight.
