7 Fast Facts About Animal Farting

Anyone who’s had a pet can testify that dogs and cats occasionally get gassy, letting rip noxious farts and then innocently looking up as if to say “Who, me?” You may not have considered the full breadth of animal life passing gas in the world, though—and not just mammals. In a new book, ecologist Nick Caruso and zoologist Dani Rabaiotti detail the farting habits (or lack thereof) of 80 different animals. Here are seven weird animal farting facts we learned from Does It Fart?.

1. FOR ONE FISH, FARTING IS AN EMERGENCY.

The diet of the Bolson pupfish, a freshwater fish found in northern Mexico, can lead to dangerous levels of gas. The pupfish feeds on algae, and it can inadvertently eat the gas bubbles that algae produces in warm temperatures. The air inflates the fish’s intestines and distends its belly, messing with its equilibrium and making it difficult to swim. Even if it tries to bury itself in sediment at the bottom of a pool, as Bolson pupfish are wont to do, the air causes the fish to rise to the surface, where it’s at risk of being eaten by a bird. If the fish doesn’t fart, it will likely die, either from predation or because its intestines rupture under the pressure of the trapped gas.

2. MANATEES USE FARTS AS A SWIMMING TECHNIQUE.

The Bolson pupfish isn't the only animal that needs healthy farts to maneuver underwater. Buoyancy is vital for swimming manatees, and they rely on digestive gas to keep them afloat. The West Indian manatee has pouches in its intestines where it can store farty gasses. When they have a lot of gas stored up, they’re naturally more buoyant, floating to the surface of the water. When they fart out that gas, they sink. Unfortunately, that means that a manatee’s ability to fart is vital to its well-being. When a manatee is constipated and can’t pass gas properly, it can lose the ability to swim properly and end up floating around with its tail above its head.

3. TERMITE FARTS ARE A SIGNIFICANT SOURCE OF GLOBAL EMISSIONS.

They’re not as bad as cars or cows, but termites fart a lot, and because they are so numerous, that results in a lot of methane. Each termite only lets rip about half a microgram of methane gas a day, but every termite colony is made up of millions of individuals, and termites live all over the world. All told, the insects produce somewhere between 5 and 19 percent of global methane emissions per year.

4. FERRETS ARE SURPRISED BY THEIR OWN FARTS.

Ferrets are quite the fart machines. They not only let ‘em rip while pooping—which they do every few hours on a normal day—but they get particularly gassy when they’re stressed. The pungent smells are often news to their creators, though. According to the book, “owners often report a confused look on their pet’s face in the direction of their backside after they audibly pass gas.” And you don't want your ferret to get really scared: Their fear response involves screaming, puffing up, and simultaneous farting and pooping.

5. A BEADED LACEWING’S FARTS CAN BE DEADLY.

A winged insect known as the beaded lacewing carries a powerful weapon within its butt, what Caruso and Rabaiotti call “one of the very few genuinely fatal farts known to science.” As a hunting strategy, Lomamyia latipennis larvae release a potent fart containing the chemical allomone, paralyzing and killing their termite prey.

6. WHALE FARTS MAKE QUITE THE SPLASH.

As befits their size, whales produce some of biggest farts on the planet. A blue whale’s digestive system can hold up to a ton of food in its multiple stomach chambers, and there are plenty of bacteria in that system waiting to break that food down. This, of course, leads to farts. While not many whale farts have been caught on camera, scientists have witnessed them—and report them to be “incredibly pungent,” as Rabaiotti and Caruso tell it.

7. NOT ALL ANIMALS FART.

Octopuses don’t fart, nor do other sea creatures like soft-shell clams or sea anemones. Birds don’t, either. Meanwhile, sloths may be the only mammal that doesn’t fart, according to the book (although the case for bat farts is pretty tenuous). Having a belly full of trapped gas is dangerous for a sloth. If things are working normally, the methane produced by their gut bacteria is absorbed into their bloodstream and eventually breathed out.

The woodlouse has an odd way of getting rid of gas, too, though it’s technically not flatulence. Instead of peeing, woodlice excrete ammonia through their exoskeleton, with bursts of these full-body “farts” lasting up to an hour at a time.

‘Water’ in Kansas City Woman’s Ear Turned Out to Be a Venomous Brown Recluse Spider

Susie Torres, a resident of Kansas City, Missouri, woke up on Tuesday morning with the distinct feeling that water was lodged in her left ear. She likened it to the swooshing sensation that can often happen after swimming, WDAF-TV reports.

Instead of waiting for the problem to resolve itself, Torres went to the doctor—a decision that might have saved her from some serious pain. The medical assistant was the first to realize something was alarmingly amiss, and immediately called for backup.

“She ran out and said ‘I’m going to get a couple more people,’” Torres told 41 Action News. “She then said, ‘I think you have an insect in there.’” For many people, the thought of having any live insect stuck in an ear would be enough to cue a small- or large-scale freak-out, but Torres stayed calm.

The doctors “had a few tools and worked their magic and got it out,” Torres said. The “it” in question turned out to be a spider—and not just any harmless house spider (which you shouldn’t kill, by the way). It was a venomous brown recluse spider.

“Gross,” Torres told WDAF-TV. “Why, where, what, and how.”

Miraculously, the spider didn’t bite Torres. If it had, she would’ve ended up visiting the doctor with more than general ear discomfort: Brown recluse bites can cause pain, burning, fever, nausea, and purple or blue discoloration of the surrounding skin, according to Healthline.

Torres may have remained admirably level-headed throughout the ordeal, but that doesn’t mean she’s taking it lightly. “I went and put some cotton balls in my ears last night,” she told WDAF-TV. “I’m shaking off my clothes, and I don’t put my purse on the floor. I’m a little more cautious.”

Is this the first time an insect has posted up in the ear of an unsuspecting, innocent human? Absolutely not—here are six more horror stories, featuring a cockroach, a bed bug, and more.

Why You Should Never Shower With Your Contact Lenses In

Contact lenses offer a level of convenience for those with less-than-perfect vision that glasses can hardly compete with, but that doesn’t mean the daily struggle of taking them in and out of your eyes doesn’t wear on you. If you get a little lazy and decide it’s fine to leave them in your eyes during showers or pool parties, think again.

According to Popular Science, a 41-year-old woman in the UK lost sight in her left eye as a result of frequently showering and swimming without removing her contacts. The culprit was Acanthamoeba polyphaga, a protozoa that crawled into her eye and caused a cornea infection called Acanthamoeba keratitis. After two months of pain, blurry vision, and light sensitivity, the woman sought medical attention at the Manchester Royal Eye Hospital, where doctors discovered a ring shape in her left eye and a hazy layer covering her cornea. Upon testing her vision, they found that her left eye was now 20/200, which counts as legally blind in the United States.

Leela Raju, an ophthalmologist and cornea specialist at New York University, told Popular Science that the single-celled organisms “can be anywhere,” including pools, hot tubs, showers, dirty saline solution containers, and even tap water. Lens-wearers make up around 85 percent of those who get infected, and experts think it may be because the amoeba can latch onto a contact lens more easily than a bare eye.

Though Popular Science reports that Acanthamoeba keratitis only affects one or two people out of every million contact wearers each year, that’s no reason not to be careful. If you do catch it, you’ll likely need a cornea transplant, and even that won’t necessarily restore your eyesight to its previous state—after her transplant, the UK woman’s left eye now has 20/80 vision.

“It’s just a long road, for something that’s totally preventable,” Raju says. In addition to removing your contacts before swimming, showering, or sleeping, you should also refrain from reusing saline solution, make sure your contact case is completely clean and dry before filling it with more solution, and check out these other tips.
