When do sloths poop

There was absolutely no mistaking what was about to happen. The brown-throated sloth Bradypus variegatus is one of two sloth species found in Costa Rica. They live mostly solitary lives high in the forest canopy, with small home ranges of about 5. Adorable as they are, you might think twice about wanting to snuggle a sloth.

All three-toed sloths have unique hair with cracks along the surface that absorb water to nourish colonies of hydroponic algae.

Despite what we humans would consider highly questionable personal hygiene habits, sloths are incredibly fussy poopers. So every time a three-toed sloth needs to defecate it makes the slow, arduous journey down from the canopy and onto the forest floor, where it poops below the same tree every time.

Three-toed sloths cut down on the inconvenience by only pooping an average of once every week, a frequency that would have most of us downing laxatives and praying for death. Infrequent pooping is normal for sloths, which eat toxic leaves from just a few species of trees and have the slowest rate of digestion of any mammal species. We were patrolling a tiny patch of cloud forest for just two hours on one night, so to stumble on a sloth making its pre-potty descent was preposterously lucky.

Infrequent bowel movements are also a built-in safety feature. Traveling down from the canopy also burns a lot of energy for slow-moving sloths, and scientists estimate that each trip costs a sloth about 8 percent of its daily energy needs.

The tradeoff for this infrequent schedule is that by the time a sloth is ready to go, they have quite a backlog of, ahem, inventory waiting to move. Scientists estimate that with each dump, sloths lose about one-fifth of their body weight. We stood quietly as the sloth swung down the last few feet of vine, descending head first before plopping awkwardly onto the forest floor.

It righted itself, sitting on the ground and grasping the vine with each of its front claws. Then it began to wiggle, rustling its posterior around in the leaf litter in front of an audience of 30 tourists trying desperately and unsuccessfully not to giggle.

After a few seconds our guide very thoughtfully turned off his spotlight to allow the poor creature a shred of privacy. Go Further.

They display their sluggish traits in their bathroom habits as well, only defecating every five to seven days. Do sloths die when they poop? Over 50 percent of sloths die when they defecate.

This is because most sloths climb down out of the protective trees to poop on the ground. They use a lot of energy during the process, leaving them vulnerable in the time after as they rest and regain strength. Do sloths poop in the same spot? Wild sloths often poop in the same spots.

That is why it is common to find their poo piles at the base of specific trees. Other sloths, particular three-toed sloths, often dig a small hole and then defecate inside it.

Do sloths dance when they poop? Experts have noted a certain movement that sloths make during their bathroom routine. Oh, and it all comes out in one push. Pooping is really the only reason for a sloth to ever leave its tree, and it's the only time they have to stand upright. According to Cliffe , once sloths make their way down from their trees, they do a 'poo dance' to dig a small hole to go in.

After the deed is done, they do another little dance to slightly cover it up, before heading back up, presumably feeling a whole lot lighter than they were on the way down.

Since pooping is something all animals do in one form or another, why do sloths wait such a long time between bowel movements, and why do they risk their lives, when they could easily just rain poo down from the treetops like other canopy dwellers do? In short, no one really knows. Bittel says that one of the best hypotheses — posed by a team of researchers from the University of Wisconsin back in — is that sloths poop in such a weird way to keep a balance between them and moths.

The team suggests that, in a weird symbiotic relationship, moths that live on sloths help fertilize a type of algae in the sloths' fur. This algae is important to a sloth's survival because it gives the fur a greenish hue — camouflaging the creature from predators — and possibly providing nutrients when eaten or absorbed through the sloth's skin.

So the sloths might go down to the ground to poop so they can provide a place for the moths to lay eggs, ensuring their life cycle. Though, according to Cliffe , this hypothesis doesn't really hold up to scrutiny, because of the danger a sloth faces on the ground — over half of all sloths die while outside of their trees — and sloths bred in captivity do not need moths or algae to survive, and still do it anyway.

Instead, she says that it may have to do with sex.
