WTF Fun Facts12637 – Cow Burps Seen From Space

by

While it may be kind of funny, it’s really not a good thing that the methane emissions from cow burps can be viewed from space. That methane actually gets trapped in the earth’s atmosphere and contributes to climate change.

These emissions were detected by an environmental data company called GHGSat. Their high-resolution satellites saw the emissions in February, but it took until April to confirm their suspicions.

The burping cattle reside on a feedlot in California’s Joaquin Valley. According to CNN: “If these emissions were sustained for just one year, enough gas would be released ‘to power 15,402 homes,’ the company said.”

Farm cattle contribute to 10% of the greenhouse gas emissions generated by human activity around the world. In California alone, there are 650,000 beef cows.

This marks the first time that scientists have been able to use satellite imagery to pinpoint methane emissions from cattle farming.

CNN explained the process:

“The company has three high-resolution satellites in orbit, which it has previously used to measure emissions from open-pit coal mines. Each satellite is just the size of a microwave oven, says GHGSat. “This is really pushing the envelope of our capabilities,” said Wight. “What’s unique about us is we can really kind of get to the source” of emissions, focusing in on specific feedlots. Each satellite flies over a designated location for just about 20 seconds, taking a quick “snapshot” of emissions, Wight said. Over time, regular monitoring with these satellites could create a “temporal picture” showing the change in emissions over time, allowing farmers to, for instance, test out the impact of different diets on cows’ methane emissions.” – WTF fun facts

WTF Fun Fact 12636 – A Medical Device That’ll Make You Squirm

by

Sure, it sounds gross. It is gross. But so is a lot of the creative stuff doctors do to keep us alive.

As it turns out, the resurgence of therapies that use maggots and leeches has saved thousands of lives. Doctors can use them because they are FDA-approved as medical devices, despite being living creatures.

Now, no one heads to the local community garden or dumpster to get medicinal leeches and maggots. They are created in labs within very specific parameters.

So, let’s start with maggots. How can they possibly be medicinal?

The maggots used in medicine are the larvae of bottle-green blowflies. Because maggots only eat dead skin and not living skin, they’re actually perfect for cleaning infected wounds. Instead of having some first-year resident scrubbing out your open wound, maggots are even more gentle by comparison. In fact, since they’re eating dead tissue that’s already numb, you don’t feel the chomping at all. And they do a darn thorough job!

Leeches, on the other hand, are known as blood drinkers. Both of these creatures have been used in medicine for thousands of years, but are just making a comeback. However, leeches weren’t always applied in helpful ways in the past. Now, they’re used to clean up pooled blood in the body.

According to Discover Magazine: “When blood starts pooling instead of circulating, the area swells, and the lack of fresh, oxygenated blood causes skin tissues to die. Leeches can prevent that from happening.”

In the 1980s, as more wounds became resistant to antibiotics, a few doctors wanted to try maggots again and got some men at the VA hospital to agree. After the trials worked, the doctor in charge realized that in order to share the maggots with colleagues, he had to file paperwork with the FDA, and they turned out to be hard to regulate. But it was possible and in 2003, the FDA approved maggots as a medical device. Six months later, leeches were approved as well.

Obviously, not all hospitals are keen to use them (and patients aren’t generally big fans of the idea either). – WTF fun facts

WTF Fun Fact 12631 – Killer Friendships

by

It’s not so easy to monitor giant sea creatures like killer whales close enough to know about their social lives. But thanks to drone footage, we’ve recently learned that killer whales are a lot more social than most people give them credit for.

By tracking a pod of 22 killer whales for ten days, marine researchers noticed patterns in behavior that resembled complex relationships among some pod members that they think relate to the species in general.

While killer whales live their entire lives in the same pod, they’re not equally close to all members. Just like a group of humans, they let relationships come and go over time, getting close to some members, but then growing into other relationships over time.

More specifically, researchers noticed that the whales showed a preference for another specific group member. They would surface together and touch each other more often than they would other pod members.

These behaviors signal a desire to cooperate and be social with one other whale – a “best friend,” if you will. Adding to the hypothesis is the observation that these “besties” tended to be of the same sex and age.

According to an interview by ScienceAlert with behavioral ecologist Darren Croft from the University of Exeter:

“In many species, including humans, physical contact tends to be a soothing, stress-relieving activity that reinforces social connection. We also examined occasions when whales surfaced together – as acting in unison is a sign of social ties in many species.”

Apparently, the older the whale, the more anti-social they tend to be. That’s a behavior mirrored in humans as well. – WTF fun facts

WTF Fun Fact 12628 – Mr. Goxx, the Crypto Trading Hamster

by

Not only did a hamster named Mr. Goxx have more success at trading crypto than most people, but he also had 18,000 Twitter followers at the time of his death in November of 2021.

Owned by two friends in Germany, Mr. Goxx used his cage to make “predictions” about cryptocurrency.

The BBC explained:

“The business-minded rodent has a trading office attached to his regular cage. Every day, when he enters the office, a livestream starts on Twitch, andhis Twitter accountlets followers know: Mr Goxx has started a trading session.

By running in his “intention wheel”, he selects which cryptocurrency he’d like to trade, as the wheel spins through the different options. His office floor has two tunnels nearby: one for buy, one for sell.

Every time he runs through a tunnel, the electronics wired to his office complete a trade according to Mr Goxx’s desires.”

His handlers would stream him live on Twitch, where thousands would watch him make his moves.

Considering he only began his career on June 12, 2021, he was pretty successful. Though with the current crypto downturn, we’re not sure how his former portfolio is looking these days.

But he taught us what his owners set out to teach, which is that a hamster making random choices still makes better choices than most cryptocurrency investors. –WTF fun facts

WTF Fun Fact 12620 – Home Alone’s Spider Guest Star

by

There have been some famous and controversial guest stars in the Home Alone movies, but this one takes the cake.

We know it came out a long time ago (1990, to be exact), but perhaps you’ve seen the original Home Alone movie recently. And if you have, you likely remember the scene when bad-guy Marv, played by Daniel Stern, gets caught up in Kevin McAllister’s (Macauley Caulkin) set of booby traps. In one particularly cringe-worthy scene, he ends up with a tarantula on his face.

Now, tarantulas are venomous, but that venom doesn’t do humans any real harm. The worst that can happen is that they bite you and it hurts. Still, most of us want to avoid that.

Normally, a life-like tarantula would be created by a props department for use in a movie. And Home Alone’s propmasters did, indeed, make a spider for the scene. It’s just not the one that ended up on David Stern’s face. That one was real. And his name was Barry.

Stern told the story in a long Facebook post that read:

“I’ve talked about the stunt guys doing crazy things, I’ve talked about my love of doing physical comedy, but one of the most surreal moments of the film was the scene with the tarantula crawling across my face. People who meet me are always curious if the tarantula was real, if my scream was real, and if I was scared, crazy or both. The answer to all three of those questions is “Yes.”

My memory might be off and I will happily stand corrected if anybody has better info but here is how I remember it:

When I first read the script and talked to Chris Columbus, I thought the tarantula in the scene was going to be a mechanical one and when I showed up on set, sure enough the incredible crew in the prop department had made a very life-like spider replica which could move a bit, as well as a version that didn’t move. I told them I thought I could help sell it, with my great acting abilities and all… They were polite but not convinced. To insure that the “gag” was going to work, they brought in a different crew member, this one from the animal wrangling department. He had a cage and in this cage was an exact replica of the replica that the prop department had made. But you could definitely see by the way it moved that this was no fake, but a creature of royalty in the natural world. I was a little intimidated for the first time in the movie. The wrangler introduced me to “Barry the Tarantula” (possibly mis-remembering his name, apologies). They had Barry crawl around on my hand and head. I asked if Barry was trained and was told they had been working with him for a few days but tarantulas are kind of tough to train. I asked if his poison had been removed, and was told that if the poison was removed, Barry would die. I said, “Right, but if the poison isn’t removed, then I’m gonna die. See where I’m going here?!” “Just don’t make any sudden, threatening moves and you’ll be fine.” “But I’m going to be screaming in Barry’s face. Do you think he’ll feel threatened by that?!” “Barry doesn’t have ears. He can’t hear. Relax. “

I think I made one last feeble attempt to honor the hard work of the prop department and use the replica, but once the director saw Barry in action, the Barry Action Figure was put on the sidelines. I remember Barry crawling around my face. I remember trying not to piss off Barry. Once I got used to him and what he was doing, he turned out to be a great scene partner. I think I felt comfortable enough to have let out that scream right at him in the scene, but there’s another legend that says I only mimed it and added in the scream later. (I would love for the powers-that-be at 20th Century Fox to release the original footage to see if I screamed or mimed, so we can settle this “controversy” once and for all – and the world can finally be at peace.) Either way, the scream came out pretty good and was an homage to the shower scene in “Psycho”. I then had to beat Joe Pesci with a crowbar. And we all know that even though it was pretend and funny and a fake crowbar, it’s a thousand times more dangerous pissing off Joe Pesci than pissing off a venomous spider that’s crawling on your face.

Here’s to Barry! The greatest tarantula I have ever acted with!”

WTF Fun Fact 12618 – Pauline, The Presidential Cow

by

Until the late 19th century, presidents brought their own cows to the White House to provide milk. There was no dairy delivery in Washington DC at the time.

When President William Howard Taft’s cow Mooly Wooly died in 1909, it was replaced by Pauline Wayne, a 1500-pound Holstein-Friesian. She was a gift to the Taft family from the farm of Senator Isaac Stephenson of Wisconsin.

The 4-year-old black and white bovine was the last presidential cow, but by far the most famous. The media appears to have been obsessed with her. Her arrival was covered by The New York Times, and her exploits appeared in publications from The Evening Independent in St. Petersburg, Florida, to The Milwaukee Sentinel.

One particular bit of drama was covered far and wide. Pauline was visiting the International Dairymen’s Exposition in Milwaukee in 1911 (with her milk sold in souvenir bottles for 50 cents each). But on the trip home, she went missing.

We always figured it would be hard to lose a cow, especially the President’s cow. But it happened.

It turned out Pauline’s private car was accidentally hooked up to a train carrying cows to slaughter at the Chicago stockyards. Can you imagine the scandal?!

Luckily, after a series of frantic telegraphs from the dairy show, train attendants ended up locating Pauline’s car as newspapers reported how she “narrowly escaped death.” – WTF fun facts

WTF Fun Fact 12613 – Frogs Barf Their Guts Out

by

When we saw a webpage titled “Frog Vomit: Everything There is to Know,” we knew there would be something great to share with you. And by “great,” we mean we hope your stomach has already committed to holding down your breakfast because we’re going to talk about barf. (Emetophobics – that is, people who have a fear of vomit – turn back now.)

Ok, so most frogs have a unique way of tossing their cookies, so to speak. The little creatures can’t just hurl the way the rest of us do.

When we vomit, it’s because of signals in our brain that contract all of our major muscle groups – diaphragm, chest wall, abdominal muscles – put so much pressure on our stomachs that the contents are then forced up through our throats and through our mouths. You probably know the feeling. But next time you have to heave, just be glad your stomach is staying where it is because that’s not the case for most frogs.

No matter what you think of vomiting, we must be able to do it because it can keep us safe from anything toxic being absorbed into our bloodstream and killing us. So frogs are lucky, too, because they CAN vomit. It’s just a bit more of a production.

Frogs expel the contents of their stomach via a full gastric eversion. And while your worst hangover might have felt like that, it wasn’t. A full gastric eversion is when a body doesn’t just eject vomit, it ejects the entire stomach organ.

When frogs puke, they actually see their stomachs outside of their bodies. Of course, it doesn’t freak them out because that’s just how their species rolls. But what we find fascinating is that their stomach can just be out there, all like “hello, world!” and then go back in without much drama.

According to the experts, frogs can even give their stomachs a bit of a dust-off while they’re at it, wiping their bellies clean of whatever might be stuck in there causing a problem. Seriously, they’ll use their little froggy hands to wipe it right off, using the front, right hand (obvs). (Ok, we also didn’t know this, but the front, right hand of a frog is the closest to their expelled stomach due to the way the stomach is positioned in their bodies.)

If you’re wondering what happens next, it’s all relatively routine after that. They just pick their expelled organ up, plop it back in their mouths, and swallow it. After all, it’s the only way back in!

And there’s no chance of them biting it either since frog teeth (which, we’ll admit, we never really thought about) are only used to keep food in, not for chewing.

Frogs vomit for many of the same reasons we do – because there’s something in their stomach that is toxic, inedible, or simply too big (buffet-lovers, you know what we mean). Frogs can even vomit due to motion sickness!

Now, if something very unnatural happens in their environments and they cannot re-swallow their stomach for some reason, the frogs will suffocate and die. So if you see the little guys (and gals) in a rough situation, give them a minute to swallow before you interfere.

If you got this far, we know what you’re thinking. So there’s a video below where you can see a frog barf its stomach out. You’re welcome. (Oh, and if the pedant in you wants to point out that this is a toad, please note the fun fact that a toad is a type of a frog and that there is no official scientific distinction between the two creatures.) –WTF fun facts

WTF Fun Fact 12612 – The Cowbird’s Secret Password

by

Cowbirds (Molothrus ater) have an interesting way of parenting.

Females (known as “brood parasites”) use all their energy to produce eggs and can even lay around three dozen each summer. It seems like a lot of babies, right? But they’d never know because they abandon them all to whatever feathery foster parents they can find. They lay their eggs in the nest of other birds and expect those birds to raise their young. They’ll even lay their eggs in a nest with other chicks already in it and expect the resident birds to evict their own young in favor of the newcomers!

Even more interesting is that they don’t choose other cowbirds – the babies are raised by completely different species of birds. There are at least 220 other species of bird that could find cowbird eggs in their nest one day, but individual females tend to choose one species with which to leave all of their eggs.

Cowbirds have been a challenge for scientists to understand because it’s hard to follow and get to know birds that don’t build nests. But we’ve had more luck in recent years as their habitats have become smaller, and they’ve moved closer to humans (although that’s not really a good thing for the birds).

So, you may wonder how cowbirds learn to become cowbirds if they are raised by other species. And that’s where the really interesting fact comes in.

Cowbirds eventually find their own kind and spend the rest of their lives associating with other cowbirds. They reunite with their species as juveniles, even though there’s no reason they should have the skills to recognize that they aren’t like their foster parents. (Bird brains aren’t that big.)

So how do cowbirds come to recognize one another? They have a password or “secret handshake” deal going on. Technically, it’s a very specialized chatter call. No matter their age, they can take to the trees, make their calls, and other cowbirds will come and find them. – WTF fun facts

WTF Fun Fact 12610 – The Rules Of the Aquatic Road

by

Manatees are often called “sea cows” because they’re big, slow, and gentle. And perhaps other animals have just learned to respect them for it.

We were surprised to find out that not only do manatees native to the Gulf of Mexico and the Caribbean Sea migrate to Florida each year for winter, but they become a well-respected part of the aquatic ecosystem.

In fact, even alligators will treat them like guests and give them the right of way if they swim through each other’s paths. There have been no recorded attacks on manatees by alligators, even though manatees can get a bit pushy when they don’t get their way. They’ll even swim up to and “bop” an alligator that does not yield.

While the alligators don’t know this, their gesture is helping save the endangered creatures, who have died in droves over the last decade.

And even Florida politicians seem to respect the manatees. In 1979, Florida Governor Bob Graham designated November as Manatee Awareness Month. Every governor has renewed the proclamation during their tenure.

WTF Fun Fact 12609 – Unexpected Tenants Cause a Buzz

by

Justin and Andrea Isabell never had plans to invite tenants into their 100-year-old Perkasie, Pennsylvania home. But nature finds a way.

The couple went viral in 2020 after Tropical Storm Fay rolled through and left them with a mysterious substance running down the walls of their mudroom. Justin decided that the best way to solve the mystery was to taste the substance which (lucky for him) was honey.

“After the recent tropical rainstorm soaked our area, we walked in the house through the backdoor and were faced with a stream of something coming down the walls,” Andrea told TODAY. “I was afraid it was water damage, but my husband made a closer inspection to discover it was honey. We were pretty surprised and didn’t understand how that could happen.”

Only after the discovery did they see the bees swarming around their rooftop. They had never spotted nor heard that creatures before that.

“I was pretty overwhelmed imagining what a mess this would be to clean up combined with the costs of repair to the house after the bees were removed,” Isabell said.

The clean-up only involved removing the honey and the comb. It turns out the bees had largely given up on their squatting rights after the rainstorm damaged the honeycomb.

“The comb was damaged from the rainstorm and they’re too smart to stay and have that happen again,” Isabell said. “We will still be having the comb removed and see if we can determine how long we had unknown guests.”

The couple’s Facebook photos went viral, and even show Justin licking the wall.

In their final update, they told those following the story:

“FINAL UPDATE: Bees naturally swarmed off due to the damage to their hive that caused the honey leak the Sunday/Monday after all of this hit the internet. They were found 2 days later as a massive swarm in a neighbor’s tree. The beekeeper, from Yerkes Farm, collected all bees and queen and re-hived them at his location. The bees survived. My house has not been opened up yet as the bees aren’t an issue any longer… when I open the wall, I will take pictures if hive is significant.” – WTF fun facts

WTF Fun Fact 12606 – Octopuses Getting Punchy

by

Octopuses are incredibly smart. In fact, we’re only just now starting to learn how their complex brains work.

Take this factoid, for example. Octopuses need so much intellectual stimulation that those in captivity require games and puzzles to keep them from eating off their own arms out of boredom!

But did you know octopuses also have a bit of a mean streak?

Researchers have observed the creatures punching fish in the past – everything from a warning “boop” to a “curl up and let ’em have it” punch. Punching is pretty rare, but in many cases, the researchers could ascertain some reason for the punch. Usually, the octopus was trying to keep the fish from spoiling its meal.

However, sometimes octopuses punch fish for revenge. And revenge isn’t something we usually think of as relevant to underwater creatures.

More recently, Eduardo Sampaio recorded the underwater action. He also concluded that some octopuses seem to haul off and punch their hunting partners for no reason at all. That is, they don’t stand to benefit in any way from punching the fish.

Sampaio even posted a video to Twitter to illustrate the punching action:

So, apparently, “throwing a sucker punch” is yet another factoid we can add to humanity’s ever-growing list of things we know about but can’t explain when it comes to octopuses.

WTF Fun Fact 12602 – Lopburi’s Monkey Buffet

by

Lopburi, Thailand, is the kind of place that no one needs to be convinced to visit. It’s one of the country’s oldest cities, holds the oldest ruins, and is just generally stunning to look at overall. The only issue for most people is that it’s a little hard to get there. And what usually seals the deal is the fact that long-tailed macaque monkeys roam the streets and serve as entertainment.

In order to thank the monkeys, the residents of Lopburi hold an annual banquet for them at the site of a 13th-century temple known to house many macaques.

The macaques probably don’t care much about the dancers and other forms of entertainment on offer. Like most of us primates, they’re there for the food. And residents deliver in the form of piles of delicious fruits, vegetables, and sticky rice.

The locals believe that celebrating the monkeys brings them good luck and more tourists. But we imagine it’s also pretty fun to watch since monkeys go a little wild around piles of food. We’ve always wanted to see a monkey food fight, and the festival reportedly has plenty.

The festival itself draws tourists, but it may not be the best time to go since the macaques are pretty riled up. If you’ve ever been in a place where monkeys roam the streets you know they can be mischievous little thieves. They like to snatch phones, sunglasses, and purses, and there’s not much you can do once a monkey has your stuff.

If you’re willing to risk it anyway, the festival typically occurs at the end of November, and Lopburi is about a 3-hour drive from Bangkok. And there are food stands for the human attendees because you do NOT want to try and take a monkey’s feast. – WTF fun facts

WTF Fun Fact 12600 – Potty-Trained Cattle

by

Did you know that cattle can be potty trained with less instruction than toddlers? Some say it’s “easier” or “faster,” but that’s really going to depend on your access to and familiarity with each. Still, we didn’t realize cows would have the inclination to do it at all!

Researchers and cattle ranchers have worked together in Germany to train cattle not to pee out in the open. And it’s not a matter of cleanliness; it’s a matter of survival. OUR survival.

There are around 1 billion cattle in the world. Each pees about 10 liters (or 5 gallons) a day. It’s a lot. But we all pee, so what’s the problem?

Well, there are a couple of issues here:
1. When cows release all that urine in barns, it mixes with poop on the floor and creates ammonia, leading to air pollution for nearby people.
2. When they pee in pastures, it leeches into local waterways. And while most places are equipped with treatment facilities, not all of that infrastructure is in great shape and can be overwhelmed by the sheer amount of potential pollutants in the water.
3. Cow urine also contains nitrous oxide. This substance gets trapped in the earth’s atmosphere and can prevent heat from escaping into space, increasing our planet’s average temperature.

So, if we can prevent all this, why wouldn’t we? And we can’t stop cows from peeing, so scientists want to see if they can capture the urine in a way that allows them to control it so that it causes less harm.

Potty training cows sounds ridiculous, but so does letting them pollute our atmosphere while we do nothing. (And let’s face it, we’re not getting rid of cows any time soon.)

Of course, they had to call it “MooLoo training,” so some of this remains pretty silly. The experiment also involved a “cow psychologist,” which is not something we ever heard about at career day.

Ok, so what does cow potty training actually look like? It’s not quite as bizarre as it sounds. It’s just a special pen with astroturf that cows can be trained to pee in. The floor is created in a way that allows the urine to be captured underneath. And some of it can even be used to make fertilizer.

Cows are pretty smart, but they’re also encouraged by food – so it didn’t take them long to realize they got a snack after using the “restroom,” making it much easier to train them.

The first experiment involved 16 cattle and the researchers had 11 of them trained after about 10 days.

Now that we know “MooLoo training” works, the goal will be to automate it so it can be adopted by farmers with much larger herds.

If you’re really eager to see a cow use the bathroom, there’s a video below!

WTF Fun Fact 12591 – The Animal With the Poisonous Elbow

by

There is only one venomous primate in the world, and it’s not exactly a fierce-looking creature. The slow loris is the poison primate in question, and they’re native to Indonesia. Unfortunately, they’re also going extinct because they are thought to contain medicines and spiritual properties.

We don’t know about any of that, be we do know they pack a poisonous sac in their elbow.

It sounds like something out of a Marvel comic – a character that can deliver a striking blow with a sharp elbow to the face. But they don’t attack with their elbows.

Instead, they suck out the poison, swish it around in their mouths a little, and then deliver the venom through a bite.

Unfortunately, this doesn’t save them. They’re treated pretty brutally, and if someone plans to catch one, they typically remove its teeth. And the slow loris gets its name in part because it can’t outrun predators, especially humans.

Animals rescuers are trying to save them from their brutal fates, but studying them is hard because they’re nocturnal, secretive (and not super keen on humans who have a habit of dismembering and cooking them over fires). Go figure.

Lorises don’t typically attack other species with their poison bites – they’re far more likely to attack other lorises, which certainly doesn’t help those sustainability numbers.

While the loris is the only venomous primate, there are other venomous mammals: vampire bats, two species of shrew, platypuses, and solenodons.

But loris venom is truly gruesome causing necrosis causes necrosis (or tissue death), so victims can lose the limb affected.

This is just one more piece of proof that you can’t just blindly trust a cute face. – WTF fun facts

WTF Fun Fact 12590 – The Spider That Eats Its Mother

by

It may sound like just another day at the office for some mothers used to giving their all to their children, but some spider moms really do make the ultimate sacrifice for their young.

It’s called matriphagy, the act of eating one’s mother, and it’s rare. But it happens in a spider species called Stegodyphus lineatus.

These spiders only have one group of babies throughout their lives. And when these spider babies are born, they are entirely dependent on their mothers to regurgitate food and feed it to them so they can grow up.

And what does she get in return?

Well, to be fair, the moms don’t put up a fight. After about two weeks of motherhood, they allow their children to consume them, leaving behind only an exoskeleton.

The spiders are native to Israel, and research into matriphagy in this species showed another interesting thing. Females that had given birth actually started to digest their own tissues before their gruesome deaths. Now, that might be a sign that the species just wasn’t designed to survive motherhood. However, Dr. Mor Salomon, a postdoctoral fellow in entomology at the Robert H. Smith Faculty of Agriculture, Food & Environment of the Hebrew University of Jerusalem, also found that the ovaries and the heart were the last organs to degenerate.

It also seems that spider mothers know their time is limited because they stop maintaining their web after their babies begin to grow.

Please don’t assume that females who don’t give birth have it any easier. They also tend to sacrifice themselves when a member of the colony has babies. Researchers are still looking into whether this is conditioned behavior or part of the species’ biology. – WTF fun facts

WTF Fun Facts 12584 – Largo di Torre Argentina

by

Largo di Torre Argentina is a popular Roman tourist destination. It holds a great deal of ancient history, but that’s not why everyone goes. Many people come to see the cats. There are dozens of them climbing and napping on the ancient ruins, and while no one is supposed to feed them, you can always find cans of cat food nearby.

The location is crumbling at an alarming rate, so Rome has recently made some renovations. After all, it does hold the site of Julius Caesar’s murder by members of the Roman Senate.

Luxury fashion house Bvlgari will pay around $1.1 million to clean the ruins and build walkways through the site. Before this, people could only look down into the ruins from the street. We’re not sure how the cats feel about all this, but we will guess “cranky.” Many are not fond of people.

You might wonder how such an important historical location ended up in such disrepair in the first place, but that’s the price of expanding a city. The site was largely lost until Italian dictator Benito Mussolini set out to unearth ancient Rome and tie his dictatorship into the lore of the Roman Empire as part of a propaganda effort. They found four temples and part of the Theater of Pompey, the site of the Roman senate.

During World War II, the Largo di Torre Argentina became neglected once again, and Rome lacked the funding to restore it until recently.

And don’t worry about the cats – the feline colony is protected by the laws of the State and the Municipality. – WTF fun facts

WTF Fun Fact 12580 – African Elephant Poop

by

Elephants are the largest land mammals in the world. So it’s logical to believe that they would do everything in a big way. We just didn’t realize HOW big.

Looking at the facts, it makes sense that an adult African elephant could produce over 300 pounds of poop per day. Males can grow up to 13 feet high and weigh 7 tons (that’s 14,000 pounds!). Females weigh about half of that.

It’s no surprise that they produce so much poop, considering how much they eat and how their digestive systems work. African elephants eat about 4-7% of their body weight in grasses, herbs, fruit, plants, and trees each day. And that vegetarian diet must be doing something right because they can live to be around 70 years old.

Of course, that same diet is also hard to process, so most of it comes out in their waste products. The rest is absorbed for nutrients while they sleep.

And sometimes, those elephants need those calories when they’re on the move – they can walk up to 120 miles a day (but their average is closer to 15 miles). If necessary, they can also use that energy to run. In fact, an elephant can run much faster than a human, reaching speeds of 40mph!

But back to the fact at hand. Elephants produce about 300 pounds of dung per day. So much that 1) we’re glad we don’t have to clean it up, and 2) some animals (such as dung beetles and specific monkey species) have evolved to eat this feces. The latter makes sense since much of the food is not digested and would still contain some nutrients.

WTF Fun Fact 12578 – Mike the Headless Chicken

by

It’s hard – and gross – to think about, but the phrase “like a chicken with its head cut off” originates in a biological oddity of chickens.

You see, you can decapitate a chicken and it will continue to run. They aren’t zombies (because they’re not actually dead yet), it’s just that the animal’s spinal cord circuits still hold residual oxygen. It’s kind of a sick biological joke that the most decapitated animal has this odd feature if you think about it.

The circuits that still have oxygen to operate no longer have a brain to control them, so the spinal cord’s signals go to the legs, causing the chicken to run (typically for just a few seconds).

This is pretty rare since chickens are typically laying down when this happens, but it has certainly happened.

Now, Miracle Mike the Headless Chicken (as he was dubbed by Life Magazine in the 1940s) is a different story. Poor Mike’s owner left a tiny part of his brain stem intact with a messy chop.

On September 10, 1945, Lloyd Olsen was beheading chickens on his farm, and got a runner, but was surprised to see that he didn’t keel over immediately.

Olsen’s great-grandson, Troy Waters, told the BBC years later that his grandparents put the chicken on the screen porch for the night and were shocked to wake up and see “The damn thing was still alive,” according to Waters.

But this isn’t some sketchy legend. Headless Mike toured the country, drawing slack-jawed audiences at carnivals. It was photographed and recorded by the news in various towns and in Life Magazine.

The family had their share of interlopers who insisted on coming to see Mike but also got plenty of hate mail for not just putting him out of his (or perhaps just their) misery. – WTF fun facts
