WTF Fun Fact 12747 – Flamingos Eat Upside Down

Because of the way their heads and beaks are built, flamingos eat upside down. Well, at least that’s how their heads are positioned.

Flamingo beaks scoop up water in the areas where they feed. Then, that water is processed through a structure called the lamellae, which acts as a filter. It ensures that water, sand, and other less tasty things are then expelled back into the water while the marine creatures (such as shrimp and brine flies) that flamingos eat are trapped inside. (Another fun fact: this food is also what makes flamingos pink!)

Flamingo anatomy

A flamingo’s tongue is designed to push the water back out through these filtration mechanisms.

According to the San Diego Zoo, “Greater and Chilean flamingos are larger and feed mostly on invertebrates such as brine flies, shrimps, and mollusks. They get these food items from the bottom mud by wading in shallow water. Sometimes they swim to get their food and sometimes by ‘upending’ (tail feathers in the air, head underwater) like ducks.”

It all happens quite fast, but if you take a look at how a flamingo is built, you’ll see that eating upside down is really the only way.

Of course, flamingos breathe air, which means that while they’re attempting to feed, they need to hold their breath – something they can do for up to a few minutes at a time. They need to poke their heads up every now and then to get more oxygen.

Flamingos eat upside down even on a zoo diet

According to the zoo, their flamingos get a special diet with all the nutrients they need. But even in these cases, they still use the same upside down stature to take in their food:

“At the San Diego Zoo and the San Diego Zoo Safari Park, the flamingos are fed a special pellet diet that is made for zoo flamingos. This food has all the nutrients the flamingos need and a pigment that helps keep them “in the pink.” To allow the flamingos to eat in their normal way (taking in water and then pumping it back out), a water source just for feeding is near their food so they can get a “beakful” of water and then food—just like they would in the wild.”

Flamingo mysteries

Flamingos are interesting creatures and there are still some habits we can’t explain – such as why they sometimes stand on one foot. No one has definitively explained that behavior yet. – WTF fun facts

WTF Fun Fact 12746 – Owls Don’t Have Eyeballs

Owls have eyes, of course. But owls don’t have eyeballs.

Instead, owls have eyes shaped like cylinders (with three eyelids!). Because of this shape, owls can’t roll their eyes around while keeping their heads still. That’s why they have to move their heads around too much to look around.

How do owls see without eyeballs?

According to the Office of Science & Society at McGill University: “Since moving their torsos would likely make noise that would alert their prey to their presence, owls have evolved to have necks that can spin up to 270° essentially silently.”

But why would an owl evolve to have eye rods instead of eyeballs? Wouldn’t it just be easier not to have to move your head at all in order to see to the side?

Well, perhaps, but the benefit of having eyes shaped like rods instead of balls is that not only does it allow them to see better in the dark but it’s the optimal shape for an animal with such a small skull.

The benefit of eye rods

As you may have noticed, nocturnal animals tend to have large corneas. That’s so any light can be collected more efficiently, allowing them to see in the dark.

As it turns out, these elongated eye tubes make it even easier for them to see the way they need to, even if they do have to make more movement in order to get a larger field of vision (also called binocular vision). Without moving their heads, their visual field is about 110 degrees (a human’s is 180 degrees, for comparison).

Binocular vision

Binocular vision also lets owls see objects in three dimensions (height, width, and depth). So, it turns out an owl’s eyes are pretty perfectly suited to its lifestyle.

While some believe all of this means that owls can’t see during the day because they’re blinded by too much light, that’s simply not true. Some owls can see even better than humans in the daylight as well, despite the lack of eyeballs.

At least you never have to worry about an owl giving you the side-eye. –WTF fun facts

WTF Fun Fact 12734 – Man Wins Horse Race

For only the third time since 1980, a human has won the annual Man vs. Horse race. Ricky Lightfoot beat 50 horses (and 1000 other human runners) finishing the 22.5-mile course in 2 hours, 22 minutes, and 23 seconds. He won about $4200 for his efforts – as well as bragging rights amongst friends and foals alike.

IFL Science humorously recounted the beginning of the Man vs. Horse race:

“The idea for the race came, as you might expect, from a drunken argument in a pub. Landlord of the Neuadd Arms in Llanwrtyd Wells, Wales, overheard two customers arguing (as you do) over the benefits of people vs the benefits of horses. 

After a few more pints, as was inevitable, one of the men proclaimed that over a long distance people could equal the performance of any horse. Not satisfied with mere speculation, the landlord – Gordon Green – decided that there should be a public competition where this slurred theory could be tested. Every year since then – bar a few years where the event was canceled due to the pandemic – people have raced against horses in a constant battle for supremacy.”

Even more striking is the BBC report that “The winner of the grueling Man v Horse race has revealed he had been awake for 29 hours before the event after flying from Tenerife to claim victory…Landing at 04:00 he travelled to Wales, arriving at Llanwrtyd Wells, Powys, at 09:00 for the race start at 11:00. Crossing the line, the 6ft 4in athlete had no idea whether he had won as the people and animals take slightly different routes.”

The 37-year-old firefighter and father of 2 beat the first horse by over 2 minutes. So much for horsepower.

Apparently, Lightfoot’s family couldn’t believe he managed to win the race.

“I called my partner and said: ‘I beat the horse’. And she said: ‘You’re joking?’.
“And I said: ‘No, I did.’ She was like, ‘oh my God!'” he told BBC News.

Prior to the race, Lightfoot said he didn’t have much experience around horses.

“I’ve never rode a horse in my life. I once rode a donkey at Blackpool Pleasure Beach though,” he told the BBC.

After winning, Lightfoot headed right back home to Cumbria to report to work at 7:30 am the next day. – WTF fun facts

WTF Fun Fact 12733 – The PAWSCARS

Each year, American Humane puts on its own award show to celebrate the “furry, winged, and scaled” members of television and film casts. It’s called the PAWSCARS™, and it celebrates animal actors past and present.

American Humane has long played a role in ensuring the health and safety of animals on entertainment sets. According to their website:

“Since 1877, American Humane has been at the forefront of every major advance in protecting animals from abuse and neglect. Today we’re also leading the way in understanding human-animal interaction and its role in society. American Humane advocates for the American values of caring, compassion and hope. Our programs enrich our communities, prevent abuse of animals, and embrace the power of the human-animal bond. American Humane works in association with the American film and TV industry to help ensure the well-being of animal actors and promote the human-animal bond. They are on the set to protect animal actors. American Humane also celebrates the achievements of extraordinary dogs across the country with its annual American Humane Hero Dog Awards™. In addition, the organization enlists and works with many celebrities who speak on behalf of the voiceless that American Humane aims to protect.”

Their Hollywood initiative also includes the annual award show, which we really think should be televised since we would totally watch that (and we’re sure other animal lovers would too!).

Interestingly, the ASPCA also has Pawscers Awards, but these go to adoptable animals throughout the country, not to animal actors.

American Humane’s PAWSCER awards got the most press in 2016, when fans voted on their all-time favorite animal movies. The winners included

Favorite Animal Buddy Movie of All Time: “Turner and Hooch”

Favorite Animal Drama of All Time: “Seabiscuit”

Favorite Animal Family Movie of All Time: “Old Yeller”

Frankly, we want to know what people were thinking when they chose Old Yeller, which has a pretty devastating ending and scarred generations of children. But to each their own – the people have spoken.

American Humane’s explanation was that “Disney’s timeless classic from 1957 is credited as one of the first films to demonstrate the importance of the human-animal bond, the inextricable link between people, pets and the world we share.”

Overall, the PAWSCERS are designed to honor “some of America’s most treasured institutions.” And while we haven’t heard much about the awards in the last few years, we think it’s time to add more animal award shows to the television line up!

WTF Fun Fact 12730 – Male Kangaroos Flex Their Biceps

Male kangaroos and male humans have something in common – they flex their biceps to impress females. Researchers showed that male western grey kangaroos use their biceps both for combat and to compete for the ladies.

The Conversation interviewed kangaroo expert Rod Wells, who said that bigger biceps might mean an “additional advantage from either females finding big forelimbs sexy or alternatively the males which win the right to access the females are then strong enough to overpower any unwilling female.”

We’re not impressed by that last part.

Kangaroos have long been a symbol of strength. According to Smithsonian Magazine: “The Royal Australian Air Force used a boxing kangaroo starting in 1891. For a while, kangaroos would fight men in boxing rings. And, in fact, a male kangaroo biceps are a lot more impressive than you might think.”

Fighting and flexing kangaroos are a new concept to some of us. For example, in 2017, an Australian snapped a photo of a particularly jacked kangaroo he came across while taking his dog for a walk. While its musculature is not super common, it brought attention to the fact that kangaroos can get ripped.

According to Men’s Health: “Jackson Vincent, a 27-year-old gardener in Australia, was walking his dog Dharma on his grandmother’s property near Boodjidup Creek when he spotted the massive ‘roo. He said he’s seen kangaroos on the land since he was a kid, but few that have been that large, according to the Sun. The ‘roo was standing in the creek nearly fully submerged, and as Vincent started to take photos, it started to come at him.”

While we’re smart enough not to approach a wild animal we don’t know much about, we plan to be extra careful with kangaroos from now on. If you’re not convinced, you may want to check out the video below and watch them kick each other’s butts – it’s quite a sight!

WTF Fun Fact 12718 – Crickets Can Tell You The Temperature

Let’s get one thing out of the way up front. While we call the method of measuring temperature using cricket chirps “Dolbear’s law,” the idea was first laid out in 1881 by Margarette W. Brooks. Her report “Influence of temperature on the chirp of the cricket” was published in Popular Science Monthly, it just wasn’t noticed until after Amos Dolbear published an 1897 article called “The Cricket as a Thermometer” 16 years later.

Regardless, it’s known as Dolber’s law, and it states that there is a connection between the air temperature and the rate at which crickets chirp. And it’s accurate for the field cricket within about 1 degree Fahrenheit.

It’s kind of like counting the seconds between lightning strikes and thunder, except way more inconvenient.

However, it is true that crickets chirp more speedily as the weather warms up. Dolbear realized this because crickets chirp consistently – that makes it possible to use the numbers in an equation.

In the original paper, Dolbear said you can get the approximate temperature in degrees Fahrenheit based on the times a cricket chirps in 1 minute – but you have to do some more math.

T_{F}=50+\left({\frac  {N_{{60}}-40}{4}}\right).
In other words, T = 50+[(N-40)/4]
T = temperature
N = number of chirps per minute

If you want a shortcut for Celcius, you can use the number of chirps in 8 seconds and add 5.

Of course, there are many types of crickets, and Dolbear realized they each had a different rate of chirping. So he created new equations for other species. The problem for us is that we have to know which type of cricket we’re dealing with.

In fact, the common field cricket really isn’t the best cricket to use since its age, and whether it’s mating season can also affect the speed at which they chirp (so they’re not entirely consistent). But they’re probably good enough for a quick experiment. –WTF fun facts

WTF Fun Fact 12711 – A Ram Charged With Murder

A sheep – a ram, to be exact – killed a woman in South Sudan by headbutting her in the chest. There aren’t many more specific details, but we’d rather not have them anyway.

People have been killed this way before. In fact, a 73-year-old U.S. woman was killed in Bolton, MA after being rammed while volunteering at a livestock farm in 2021. She was caring for the sheep alone in a pen when the animal repeatedly rammed her.

But the incident in South Sudan also made headlines because we’re not used to seeing other systems of punishment. In this case, the ram itself has been sentenced to three years in jail. Since it sounds like the animal was in human captivity, it’s unclear what that means.

According to LADbible, which published the story and cited multiple local sources:

The ram was taken into police custody in South Sudanearlier this monthafter it attacked Adhieu Chaping, 45. She later died as a result of her injuries.” And, according to police, “The ram attacked by hitting her ribs and the old woman died immediately. So this is what happened in Rumbek East in a place called Akuel Yol.

LADbible quoted Major Elijah Mabor telling a local radio station:

Our role as police is to provide safety and separate fights. The ram was apprehended and currently under custody at a Police Station of Maleng Agok Payam...The owner is innocent and the ram is the one who perpetrated the crime so it deserves to be arrested then later on the case shall be forwarded to customary court where the case can be handled amicably.”

We’re not sure what it’s like to arrest an angry ram, but it sounds like a dangerous job.

The next step is to take the animal to a military camp in Aduel County headquarters in Sudan’s Lakes State for its prison sentence.

As the official said, the owner of the ram, Duony Manyang Dhal, will not be charged with a crime, but a local court determined a just punishment would be to give five of his cows to the victim’s family (who are his neighbors) as compensation.

Apparently, when the ram is released from detention, it will also be given to the neighbors.

It appears that this may be a photo of the ram (however, the news source called the 45-year-old victim an “old woman,” so we’re not sure we trust anything else after that):

WTF Fun Fact 12707 – The Role Of Goats In Argan Oil

Maybe you’ve heard of argan oil. It’s very trendy in skin and hair products and the oil is quite expensive. It comes from the nuts of Argania trees, which are found in Morocco.

But argan oil isn’t so easily harvested from these nuts. In order to make the oil easier to harvest, you generally have to wait for the nut to pass through the digestive tract of a local mountain goat first. So, yes, what we mean here is that the nuts are eaten by goats, softened by their digestive tracts, pooped out, and THEN gathered by people for creating argan oil.

Of course, there are other ways of harvesting (humans doing the hard work of peeling them) and you’ll find many companies insisting that their argan oil comes from goat-free nuts. In those cases, the goats end up being a nuisance (and all because people are squeamish).

But frankly, it’s hard to know for sure how the nuts get into human hands. And it doesn’t really matter since the oil has no traces of goat poop in it by the time it gets to you.

The other fascinating thing about the mountain goats that helped launch the argan oil industry is that they became talented tree climbers precisely because the Argania trees bear fruit. There’s not much fruit on the ground in Morocco for goats, especially in summer. Once the goats eat all the low-hanging fruit, they have no other choice than to head upward.

While there are other goats around the world that climb trees, many of the pictures we see of multiple goats in trees are probably Moroccan mountain goats getting their fruity dinners.

And because they’re goats, they end up eating the nuts as well. Since they can’t digest those, the nuts end up on the ground later on (via poop mostly, but some goats will spit them out after trying to chew them). – WTF fun facts

WTF Fun Fact 12705 – Invasive “Jumping Worms”

In a not-so-fun turn of events, people in the U.S. are concerned about an invasive species of worm that can reproduce on its own, destroy soil, and spread quickly.

Usually, worms are a vital part of ecosystems and help the soil provide nutrients to crops. But not the Amynthas agrestis, or Asian jumping worm. They’ve been troubling people since 2013 in the U.S., but they’ve been spotted far and wide now and farmers are concerned. They are native to east Asia, and Japan and the Korean peninsula in particular.

There are lots of ways worms can move around the world, but we’ve never seen them pose this kind of threat. More recently, they’ve been seen as far west as California’s Napa county (although to be fair, that’s actually closer to Japan).

We import a lot of beautiful plants from overseas for our gardens, so it’s no surprise the U.S. is now home to new kinds of worms. But these ones can cause long-term damage (and startle gardeners quite a bit!). They’re called “jumping worms for a reason.

According to The Guardian, the California Department of Food and Agriculture (CDFA) warned in a report:

“These earthworms are extremely active, aggressive, and have voracious appetites. True to their name, they jump and thrash immediately when handled, behaving more like a threatened snake than a worm, sometimes even breaking and shedding their tail when caught.”

Yikes. Good thing they’re still small.

Normally, we’d say let nature be, but it turns out that they may cost a lot of money (and even livelihoods) down the line since this isn’t the soil they’re supposed to be in. The Guardian warned: “Jumping worms can destroy a forest ecosystem by chewing through fallen leaves, in turn destroying the top layer of forest soil upon which many plants and organisms depend.”

The CDFA report continued the dire warning: “They are destructive and cause severe damage to hardwood forests, especially those consisting of maple, basswood, red oak, poplar or birch species that rely on thick layers of leaf litter that serve as rooting medium.”

Sometimes we don’t realize how important soil is to our lives, and these are capable of completely changing the nature of soil (and therefore the crops that can be grown in it).

The Guardian also provided some advice (since, as you likely know, even chopping a worm into pieces with your garden shovel isn’t going to do the job – in fact, it can just create more worms):

“Experts have recommended several strategies to detect and eliminate the worms, including using a mustard pour – a mixture consisting of water and yellow mustard seeds – over soil to drive out any worms to the surface, and covering moistened soil with a sheet of transparent polyethylene for two to three weeks until soil temperature exceeds 104F for at least three days, destroying the worm’s cocoons.”

You can also bag the worms and bake them in the sun – anything that keeps them from thriving and spreading. And you may want to double-check your potting mixes and mulches before you spread them around your yard. Even the wind can blow around their egg sacs, spreading them easily.

It may even be the case that over the last few years, leaf pick-ups that turn our autumn leaves into compost have helped spread the worms.

WTF Fun Fact 12701 – Like A Fish Out Of Water

We may not all love bees, but we can’t live without them since they pollinate the crops that make the food we eat (among other integral ecological roles). That makes protecting them integral to our future.

In California, that means considering them “fish” for conservation purposes.

The law is a weird thing sometimes. In this case, it required some creative thinking in order to make sure bees got protected status under the California Endangered Species Act (CESA).

Others had argued that the Act protects only “birds, mammals, fish, amphibians, reptiles, and plants” – in other words, not insects like bees. They won the original court case, but it was just overturned by a Sacramento Court of Appeal.

According to Reuters:

“While ‘fish’ is ‘commonly understood to refer to aquatic species, the term of art employed by the Legislature … is not so limited,’ Associate Justice Ronald Robie wrote for the appeals court.
CESA itself does not define “fish,” but the law is part of the California Fish and Game Code. The code’s definition includes any ‘mollusk, crustacean, invertebrate (or) amphibian,’ Robie wrote. All those categories ‘encompass terrestrial and aquatic species,’ and the state legislature has already approved the listing of at least one land-based mollusk, the opinion said.
‘Accordingly, a terrestrial invertebrate, like each of the four bumblebee species, may be listed as an endangered or threatened species,’ Robie wrote, joined by Acting Presiding Justice Cole Blease and Associate Justice Andrea Lynn Hoch.'”

The case is Almond Alliance of California et al. v. Fish and Game Commission et al, Xerces Society For Invertebrate Conservation et al, intervenors; California Court of Appeal, Third Appellate District, No. C093542.

WTF Fun Fact 12699 – A Shark Attack Of A Different Sort

In August 1956, Leslie Nye and Richard Kirby were killed in a shark explosion. Even worse, they saw it coming. And even worse than that, they were the ones that launched the explosives at the sharks to begin with.

But before you assume they got what was coming to them, it’s important to have some context.

This was all part of a military diving exercise and the day before, an officer saw a shark approach the dive team and identified it as a potentially aggressive danger. In fact, he saw the shark swim toward men in the water and turn to its side as if to get its mouth into position to bite. However, it was scared off by bubbles from the divers.

But the next day, sharks started circling the boat again as the men were putting on their gear. Then, a decision was made to scare the sharks off (or kill them – either would have been fine at the time) so the divers wouldn’t be anxious.

That’s when two officers and two civilians boarded a dinghy with a pair of 14oz explosive charges fastened to a rope. Someone threw the rope and it wrapped around the shark’s fin, as planned.

What they didn’t plan for was the shark turning around and heading back for the boat. It ended up underneath the vessel when the charges exploded. All four men were on the boat at the time, but only Nye and Kirby were killed (Brooks and Spicer were seriously injured).

The Coroner ruled the ordeal a “misadventure.”

After the incident, there were rumors that the military was trying to test explosives during the Cold War and used the shark story as a coverup. But it’s just weird enough to be true.

WTF Fun Fact 12697 – Sharks Are Older Than Trees

Everything on Earth has evolved over millions of years to take its current form. So, in some sense, it can be hard to look back and make a firm division between a day when trees and sharks did and didn’t exist.

Still, there’s just really no comparison when you look at ever the more conservative numbers. Even if we go back to the species Archaeopteris, commonly considered the first species of “tree,” whose remains have been found in the Sahara desert, the now-extinct species “only” goes back 350 million years.

The numbers get kind of mind-blowing when you’re talking about evolution.

Sharks, on the other hand? Well, they go back 400 million years. And while that may seem like only a slight difference in number, 50 million years is A LOT of time (more than humans are really capable of conceiving).

We’re not sure which we would have guessed had come first – trees just seem older for some reason, but all evidence points to life starting in the oceans and not on the planet’s surface.

Sharks and trees aren’t something we compare very often, but both species have survived mass extinction events and hold secrets to the past that we can only dream of discovering.

WTF Fun Fact 12695 – Male Mice Are Scared Of Bananas

We may have never noticed on our own that male mice harbor a fear of the humble banana. But scientists studying the fear responses of male mice to pregnant and lactating female mice made the connection.

Long story short, male mice can be very aggressive towards baby mice (or “pups), especially virgin male mice who see them as genetic competition. That’s why female mice have evolved to produce a compound, called n-pentyl acetate, in their urine that produces a stress and fear response in all male mice (but especially virgins).

Bananas enter the equation because they also happen to emit a compound that produces a fear response in male mice. They don’t contain n-pentyl acetate but rather isoamyl (or isopentyl) acetate.

Of course, bananas didn’t evolve to scare mice, that’s just a coincidence.

According to IFL Science:

“The team bought banana oil extract from the supermarket and placed it inside the cages of male mice to measure their stress levels, which increased significantly in response. The team believe that the stress response in the mice is similar to the stress response when about to engage in a fight.”

At least now we know one more strategy for getting rid of male mice! – WTF fun facts

WTF Fun Fact 12679 – OutHorse Your E-Mail

Visit Iceland recently got a weird idea. They’ve launched an out-of-office email service called OutHorse Your Email” so you can outsource to a horse.

So, apparently, you can get a horse to write your OOO emails.

This was all brought about by a survey that found that 55% of vacationers check their email at least once and 60% said their bosses expected a response. (Of course, we’re not sure how bosses respond to horse emails, but that’s a survey for the future.)

Check this out:

It seems like a joke, right? Well, there’s a website and all you need to do is select a horse and put in your email information to generate your email.

According to IFL Science:

“The huge typing platform is then placed outside with the stunning backdrop of Iceland to complement the tip-tapping of typing horses writing the OOO emails of lazy humans. You can get your own emails written via the Visit Iceland website where Litla Stjarna Star from Hvítárholt, Hrímnir from Hvammi and Hekla from Þorkellshó are waiting to assist you.”

WTF Fun Fact 12677 – How To Survive A Date With A Spider

In many species of spiders, the last thing males do is mate. After that, they’ve done their job for the evolution of the species and are no longer needed. So females have evolved to simply eat them. They provide nutrients for the babies, after all!

It’s called sexual cannibalism and it’s one of the many facts of nature that we humans may have a hard time wrapping our heads around (or not, depending on your mate).

A few species have evolved to avoid this fate – for example, some may choose to amputate their own legs as a defense strategy in order to distract the females and get away (with the remaining legs, of course). In some sense, this makes sense since the female gets some nutrients and the male gets to hobble away with his life. It just seems a bit drastic from a human perspective.

Other spiders have learned to weave silk around the legs of the females before mating so they can make an easier escape afterward, which seems like a wise move as long as the female survives to produce her young.

The Philoponella prominens have developed a strategy whereby they use their two front legs to propel themselves out of reach of the females, getting away with all of their legs and their lives (if they hit the eject button in time, at least).

Since Philoponella prominens don’t have venom, the males who get cannibalized are in for a rough ride before death. The females produce over 400 feet of silk to “mummify” them, typically winding it so tight that they’re crushed and/or suffocated.

Not only are these spiders interesting for their actions but how they achieve them. Most jumping spiders launch from their back legs, so jumping using the front legs leads to some more interesting questions about the evolution of these creatures, especially since they don’t have muscles in those legs.

According to Smithsonian Magazine, the researcher who made this discovery noted that “one male was able to perform the behavior six times over the course of about eight hours, but was finally killed and eaten after his final performance–perhaps being too exhausted to spring himself to safety.”

WTF Fun Fact 12673 – What’s In A (Cat’s) Name?

In unsurprising news, there’s more evidence that cats don’t care about something.

Japanese researchers did a small study (which is really all you can do when cats get involved) and found that cats seem to recognize the names of their feline housemates. However, they still don’t give any indication of recognizing their own. Whether it’s because they just don’t care is something we’ve yet to figure out.

Why should we even care what words cats recognize? Well, IFL Science put it in context the best: “Birds with vocal cords that can imitate our own can learn a variety of human words, and it’s argued some know the meaning, rather than merely mimicking. Apes taught sign language also understand the meaning of words, and more recently dogs have been found to be able to learn up to 12 toys’ names in a week – but what about cats?”

In other words, we do all of this behavioral research on animals and find these fascinating signs that, in some sense, they can organize the world in ways similar to our own. So why not take a look at these abilities in some of the most common pets?

The research was conducted by Saho Takagi, a PhD student at Kyoto University who published the results in the journal Scientific Reports. The research team tried an experiment with domestic cats living in a 3+ cat home as well as residents of Japan’s famous cat cafes.

The study does rely on one important assumption (but if you know anything about science, you know that this is often the case since that’s where we start in order to help prove things). The assumption is that like other animals, cats stare longer than normal when they are surprised by something. In this case, hearing a name they recognize.

So the team spoke to the cats and said the names of their fellow resident cats to see if they would get a reaction. And they did, at least when the cats didn’t just run off in the middle of the experiment (and one did).

But what’s interesting is that this only happened in households, not in cat cafes. And in cat cafes there tends to be a lot of turnover from adoptions (and a lot more names to remember). So it may be that the cats in those cafes never hear a name enough time to have it ring a bell.

Apparently, the cats only reacted to the spoken names. Seeing their feline roomies’ photos on a laptop didn’t have any effect. Also, hearing their own names had no effect.

There were only 19 cats involved in the study, so it’s right to be skeptical. But that’s where we often start in science. The study still showed there was statistical significance to the results, and that’s typically a sign that further research can continue until there’s enough evidence to constitute some kind of “proof.”

In the meantime, just take it as a sign that your cat ignoring its name is not necessarily them blowing you off. They may just not be able to recognize that a name belongs to them. Or they just don’t care.

IFL Science explains this is not Takagi’s first cat study: “Last year she was first author on a paper exploring the feline capacity to map the spatial location of their person or a familiar cat. Takagi and co-authors reported the cats showed surprise when speakers broadcast the voice of the person who feeds them, despite that person’s absence. The same reaction did not apply to recordings of familiar cats’ vocalizations or unrelated sounds. Previously she studied cats’ understanding of the law of physics.” –  WTF fun fact

WTF Fun Fact 12672 – Beware the “Sharkcano”

Your mother probably warned you not to swim around acidic shark-infested volcanoes, but in case she didn’t, we’re telling you now not to try it!

Only once have scientists been able to explore the Kavachi volcano in the Solomon Islands. It’s a submarine (aka underwater) volcano and it actually erupts almost constantly. But in 2015, it took a break, giving researchers the chance to check it out.

And boy did they find some stuff! It’s no surprise that they found high levels of sulfur (because it is a volcano, after all), but they were surprised to see that despite extremely acidic conditions, some creatures have managed to thrive in the craters.

There are microbial species that are common in sulfuric environments. There are also “gelatinous animals and small fish.” Oh, and a whole bunch of angry sharks.

According to IFL Science, oceanographic researchers said this is “raising new questions about the ecology of active submarine volcanoes and the extreme environments in which large marine animals can exist.”

And while that’s really cool, we’re more interested in the phenomenon they dubbed “sharkcano.” The researchers wrote: “Two species of shark, the scalloped hammerhead Sphyrna lewini and the silky shark Carcharhinus falciformis, approached the baited camera multiple times in an aggressive pattern; in some cases, sharks appeared to be swimming from greater depths inside the crater.”

Now, before you picture thousands of sharks spewing out from the depths of the ocean floor (which is the first thing we pictured), it’s definitely not going to be that wild if this volcano has a major eruption. It will, however, be a really bad time to go swimming in that area.

NASA images showed a plume developing in late May, so we may be in for a sharkcano eruption sometime soon and we’ll be able to see precisely what that entails. –  WTF fun fact

WTF Fun Fact 12655 – Alexander the Great and His Horse

King Alexander the Great spent his entire adult life trying to conquer the world on behalf of Macedonia, and by his side, nearly the entire time was his horse, Bucephalus.

The ancient writer Plutarch wrote much of what we know about the life of Alexander, including the story about how the 12-year-old future king won his noble steed.

A horse dealer tried charging Alexander’s father a very high sum for the horse (to be fair, his father was King Philip II of Macedon). No one had seemed it a good deal since the horse could not be tamed. But young Alexander saw some potential and made a deal with the horse seller – if he could tame it, he could keep it. If not, he would pay the high sum.

Of course, we know where this story goes – Alexander subdued the horse and then rode it into nearly every battle for decades until the horse died during a campaign in India.

As someone who felt he had the right to conquer the world, Alexander left his name all over it, including over 70 cities named Alexandria.

But he loved his horse Bucephalus so much that when it died in 326 BCE, he named a city Bucephala.

The ancient writer Pliny the Elder also wrote about the event:

King Alexander had also a very remarkable horse; it was called Bucephalus, either on account of the fierceness of its aspect, or because it had the figure of a bull’s head marked on its shoulder. It is said, that he was struck with its beauty when he was only a boy, and that it was purchased from the stud of Philonicus, the Pharsalian, for thirteen talents. When it was equipped with the royal trappings, it would suffer no one except Alexander to mount it, although at other times it would allow anyone to do so. A memorable circumstance connected with it in battle is recorded of this horse; it is said that when it was wounded in the attack upon Thebes, it would not allow Alexander to mount any other horse. Many other circumstances, also, of a similar nature, occurred respecting it; so that when it died, the king duly performed its obsequies, and built around its tomb a city, which he named after it” The Natural History of Pliny, Volume 2, translation by John Bostock, Henry Thomas Riley.
