Why Pooping Can Be a Life-Threatening Experience for a Sloth

Being a sloth isn’t all lazing around in trees and munching on leaves. Occasionally, the slow-moving animals have to make their way to the forest floor to do the one task no animal can escape: pooping. It’s a much more intense process than heading to the bathroom is for humans. And for a startling number of sloths, it turns deadly.

The sloth metabolism, like everything else about these odd rainforest animals, works very slowly. It can take them up to a month to digest a meal. Their extra-slow digestion means they might only take a dump once a week, if not once a month. The poor creatures are always incredibly constipated.

So when they do poop, the result is enormous. A single bowel movement could be up to a third of the sloth’s body weight—a measurement that’s 282 percent of what scientists would expect to see in an animal of that size, according to one sloth-poop analysis from 1995.

The particular bathroom routine depends on the type of sloth, though. Two-toed sloths are often fine with letting it rip from the forest canopy (woe to any animals that might be hanging out below), while three-toed sloths determinedly make their way to the ground to do their business. Once they get down to the forest floor, they dig a hole, take a poop, then cover it up with leaves and make their way back up to the canopy.

That’s where the danger comes in. Pooping on the ground is one of the most risky things a sloth can do in life. By one estimate, up to half of sloth deaths can be linked to these rare bathroom trips. Sloths can barely walk, thanks to their long claws and limbs that are designed to hang from trees; they don't support their weight on the ground very well. (They have significantly less muscle mass than other mammals.) Instead, they crawl, dragging themselves forward with their forelimbs. That makes them laughably easy targets for predators.

Scientists aren’t entirely sure why three-toed sloths take this huge risk to poop. One study has suggested it could be related to the symbiotic relationship the animals have with the critters that live in their hair, which include a specific type of potentially nutritious algae that may benefit from the journey to the ground. That hypothesis is fairly controversial among sloth experts, though, because it’s not clear that the sloths actually eat this algae, or that it makes any kind of real impact on their diet.

For now, sloths’ dangerous bathroom habits remain mostly a mystery.

Massive Swarms of Migrating Dragonflies Are So Large They’re Popping Up on Weather Radar

What do Virginia, Pennsylvania, Indiana, and Ohio all have in common? Epic swarms of dragonflies, among other things.

WSLS-TV reports that this week, weather radar registered what might first appear to be late summer rain showers. Instead, the green blotches turned out to be swarms of dragonflies—possibly green darners, a type of dragonfly that migrates south during the fall.

Norman Johnson, a professor of entomology at The Ohio State University, told CNN that although these swarms happen occasionally, they’re definitely not a regular occurrence. He thinks the dragonflies, which usually prefer to travel alone, may form packs based on certain weather conditions. If that sounds vague, it’s because it is: Johnson said that entomologists haven’t worked out all the details when it comes to dragonfly migration. They do know that the airborne insects cover an average of eight miles per day, while some overachievers can fly as far as 86.

Based on the radar footage shared by the National Weather Service’s Cleveland Office, the dragonfly clouds seem almost menacing. But, while swarms of any insect species aren’t exactly delightful, these creatures are both harmless and surprisingly beautiful, at least up close. Anna Barnett, a resident of Jeromesville, Ohio, even told CNN that witnessing the natural phenomenon was “amazing!”

Amazing as it may be to see, it’s hard to hear news about unpredictable animal behavior without wondering if it’s related in some way to Earth’s rising temperatures. After all, climate change has already affected wasps in Alabama, polar bears in Russia, and no doubt countless other animal species around the world.

6 Fall Festivals Around the World That Celebrate Animals

Where would humans be without animals? Chickens and cows give us eggs and milk, providing nourishment (and also cake). Horses, donkeys, and water buffalo are as hardworking as any person, and thanks to our pets, we always have a source of love and entertainment to come home to. It's time we celebrate animals more often, and to get you started, here are six fall festivals around the world that do just that.

1. Kukur Tihar

A big part of Tihar, a five-day Hindu festival held in late autumn in Nepal, is giving thanks to other species. Crows, believed to be the messengers of death, are worshipped on the first day. Cows are worshipped on the third, and often oxen on the fourth. The second day, though, is all about man's best friend. Dogs are described favorably in Hindu religious texts, and it’s believed that they can warn people of impending danger and even death. In a ceremony called Kukur Tihar, people place flower garlands around the necks of both pet dogs and stray dogs to show their respect. A red dot (tika) is placed on their foreheads in an act of worship, and naturally, the dogs are spoiled with lots and lots of treats.

2. Transhumance Festival

In Spanish, this festival in Madrid is called Fiesta de la Trashumancia. The word transhumance refers to the act of moving herds of livestock to different grazing grounds depending on the season. In practice, it's quite the spectacle. Thousands of sheep have been led through the streets of Madrid each autumn since the festival was formally established in 1994. Men and women in traditional garb lead the way, singing and dancing along the parade route in celebration of centuries-old shepherding traditions.

3. Monkey Buffet Festival

Visitors to Thailand’s temples are advised not to feed the monkeys (they can get awfully handsy), but the locals of Lopburi make an exception on the last Sunday of November. On this day, towers of fruit and banquet tables containing several tons of food and even cans of Coca-Cola are set up in the ruins of a 13th-century temple. Once a sheet is removed to unveil the spread, it doesn’t take long for Lopburi’s thousands of macaques to arrive. Thailand's reverence for monkeys dates back some 2000 years to legends surrounding the monkey king Hanuman and his heroic feats. Nowadays, the creatures are considered a sign of good luck in the country.

4. Woolly Worm Festival

The woolly worm is to Banner Elk, North Carolina, what the groundhog is to Punxsutawney, Pennsylvania. According to local folklore, the color of this fuzzy caterpillar can be analyzed in autumn to predict how severe the forthcoming winter will be. The 13 segments on its body are thought to correspond to the 13 weeks of winter—more black means colder weather and snow, while more brown means the weather will be fair. To make this prognostication process more official, the Woolly Worm Festival was established on the third weekend of October in 1978. This year, it will be held October 20-21. A worm race is the main event, and the caterpillar that climbs the fastest up three feet of string gets the honor of helping to predict the winter (plus a $1000 cash prize for the worm’s coach). “Patsy Climb” and “Dale Wormhardt” were a couple of past competitors.

5. Pushkar Camel Fair

The Indian state of Rajasthan is a vibrant place. It’s home to the Pink City, Blue City, and Yellow City, and it also hosts a colorful cultural event each November called the Pushkar Camel Fair. Celebrated on a full moon day of the Hindu lunar calendar, it’s one of the largest fairs of its kind in the world. The annual gathering is a chance for traders to show off their camels and livestock, while also celebrating local culture and traditions. Both the people and camels sport brilliant attire, participate in a variety of competitions, and dance to lively music. (Yes, there’s video evidence of a dancing camel, but the word dance is used loosely.)

6. Birds of Chile Festival

Held each fall in Viña del Mar along Chile's Pacific coast, the Festival de Aves de Chile celebrates the beauty and diversity of the country's birds. Festival-goers have the chance to see Chile’s national bird—the wide-winged Andean condor, which happens to be one of the largest flying birds in the world—as well as other feathered friends in their natural environment. A series of excursions and talks featuring bird experts are organized each year.
