WTF Fun Fact 13211 – Grey Cat Genes

Grey cat genes are an interesting thing. For example, did you know that most grey cats get their coloring from a “diluted” form of the black fur gene?

It’s kind of like the difference between a tortoiseshell cat and a “dilute tortie.”

Fascinating facts about grey cat genes

The melanocortin 1 receptor (MC1R) gene is responsible for black fur in cats. This gene controls the production of eumelanin in the hair shafts. In cats, there are two versions of this gene. So, an “active” version produces black or brown fur. A “diluted” version results in a grey or “blue” coat color.

The “diluted” version of the MC1R gene is caused by a specific genetic mutation. This mutation turns off the production of eumelanin in the hair shafts.

Grey cats can also have other colors in their fur, such as white, orange, or other shades of grey, and this depends on the specific genetic variations that are present. As you might have guessed, the color of a cat’s coat is determined by the interaction of multiple genes and environmental factors. The genetics of coat color can get pretty complex.

Cat fur color doesn’t tell us a lot

Grey cat fur can come in different shades and patterns. Some grey cats may have a light, silver-gray coat, while others may have a darker, charcoal-gray coat. Some grey cats may have a solid-colored coat, while others may have tabby markings or other patterns.

If you have a grey cat, you can’t necessarily tell what breed they are just by their fur color. But you can likely narrow it down if the cat is entirely grey.

The color and pattern of a cat’s coat can also be influenced by other genetic factors, such as the presence of white spotting or the agouti gene.

Grey domestic cats could be a mix of different breeds, which leads to variations in size, shape, and overall appearance. So, while grey cats share the common characteristic of having a grey coat due to the diluted form of the MC1R gene, each one still has other characteristics to be considered.

Feline parentage

Did you know a female cat is known as a molly (unless she is a purebred, then she is called a Dam). Female cats are called queens when they are pregnant or still feeding babies. Males are called “toms” or “tomcats” (and purebred fathers are Sires).

According to The Cat Fancier’s Association (cited below), there are some general rules about cat genetics.

For example, male kittens always obtain both color genes from their mothers. “The male offspring in a litter will always be either the color of the dam (or one of the colors in the case of parti-colors) or the dilute form of the dam’s color.”

On the other hand, “Female kittens take one color gene from each parent. The color of the female kittens in a litter will always be either a combination of the sire’s and dam’s colors, or the dilute form of those colors.”

We also didn’t realize that “Only the immediate parents determine the color/pattern of a kitten” or that “A kitten’s pattern can be inherited from either parent.”

There’s always something interesting to know about cats, even if it’s technical! WTF fun facts

WTF Fun Fact 13208 – A Flamboyance of Flamingos

A group of flamingos is called a flamboyance. It is also called a “colony” or a “stand,” but as you can imagine, flamboyance is far more popular.

How did it get named a flamboyance of flamingos?

The word “flamboyance” is derived from the French word “flamboyant,” which means “flaming” or “blazing.” It was originally used to describe the flamelike shapes found in the tracery of Gothic architecture, particularly in the late Middle Ages. The term was later used to describe a style of architecture characterized by elaborate and ornate decoration, as well as a flamelike appearance.

In the 19th century, the word began to be used to describe people and things that were showy, flashy, or ostentatious.

What makes flamingos so “fiery”?

Flamingos are social birds, and they tend to live in large groups (or colonies). Their bright pink or orange plumage is caused by pigments in the algae and crustaceans they eat.

The term “flamboyance” was first used to describe groups of flamingos in the 1930s, likely because of the birds’ striking coloration and the way they move in large, coordinated groups.

Their colonies can range in size from a few hundred to several thousand birds. Flamingos also establish a hierarchical social structure. Dominant birds are at the top and are typically larger and stronger. They get the best access to food and breeding sites.

Flamingos are also known for their synchronized behavior. They take off and land together and perform group displays such as head-flagging or wing-saluting during the breeding season. This synchronized behavior is thought to be used for communication and for predator detection.

While the term “flamboyance” has come to refer to any group of flamingos, it can also be used to describe any large, brightly colored group of birds or other animals that move and behave in a coordinated, showy manner.  WTF fun facts

WTF Fun Fact 13207 – The Headless Chicken Monster

Have you heard of the headless chicken monster of the sea? Well, it’s slightly less exciting than it sounds, but we’re going to tell you about it anyway.

What is the headless chicken monster?

The headless chicken monster is actually a type of sea cucumber. And as you may have guessed, “headless chicken monster” isn’t its real name.

The sea cucumber was discovered in the Southern Ocean near East Antarctica in 2017 and made headlines in 2018. It is called the “headless chicken monster” because it has long, feathery appendages that resemble a chicken’s legs. Oh, and it doesn’t have a head. It uses appendages to move along the seafloor and filter feed on plankton. It has a mouth on the underside of its body.

The scientific name of this species is Enypniastes eximia.

Discovering a “monster”

The creature was seen using an underwater camera system. It’s thought to be the first sea cucumber of its kind to be observed in the Southern Ocean and has yet to be fully studied by scientists.

According to Smithsonian Magazine (cited below):

“While conducting a video survey of the deep, dark waters of the Southern Ocean, Australian researchers recently captured footage of a host of funky creatures that swim about near the sea floor. But the team was particularly surprised when a pink, blob-like animal fluttered into shot, propelled by a little pair of fins. It looked “a bit like a chicken just before you put it in the oven,” Dirk Welsford, the program leader for the Australian Antarctic Division, tells Livia Albeck-Ripka of the New York Times. The researchers had no idea what it was.”

Interestingly, scientists seem to have known about the creature since the 19th century, it’s just rarely sighted. It wasn’t named its own species until the recent footage.

The future of E. eximia

The Southern Ocean is a remote and inhospitable environment, and scientists know very little about the sea creatures that live in this region. The discovery of E. eximia is important because it highlights the diversity of life in the Southern Ocean and the need for further research in this region.

Due to its remote habitat and deep waters where it lives, wildlife officials don’t consider the species endangered. CNN reported that the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) proposed creating three large protected areas along East Antarctica to study the unique marine life there. However, Russia and China have blocked the proposal.  WTF fun facts

WTF Fun Fact 13206 – The Bombardier Beetle

You may have heard of the Bombardier beetle since they have a rather interesting ability. Or as National Geographic (cited below) puts it, “the infamous ability to synthesize and release rapid bursts of stinky, burning-hot liquid from their rear ends.”

Tell me more about the bombardier beetle!

There are actually over 500 species of bombardier beetle (and about 40 in the US alone). These creatures live in many different types of ecosystems. The boiling hot chemicals they can shoot out of their rears as a defense mechanism can reach temperatures up to 212 degrees Fahrenheit. And the beetle can shoot the spray multiple times in quick succession. The spray can also produce a loud popping noise as it is released, adding an extra deterrent.

The details are even more fascinating.

In the bombardier beetle, special cells produce hydroquinones and hydrogen peroxide which then collect in a reservoir. In order to spray, the beetle has to open a valve controlled by a muscle in order to release the chemicals into a separate “reaction chamber.” This chamber is lined with cells that catalyze the chemical reaction that makes the compounds hazardous to the beetle’s predators.

The catalases and peroxidases lining the chamber also aid in the reaction that generates enough heat to bring the mixture to the boiling point (though some of it becomes vapor). The pressure created by the gases closes the valve and expels the chemicals at high speed. Amazing, right?!

Should I be afraid of this creature?

People don’t need to be afraid of the bombardier beetle. They’re too small to hurt humans (about the size of a fingernail), and they don’t go around indiscriminately spraying. They use that function only as a defense mechanism against predators.

Bombardier beetles usually keep to wooded areas and fields and don’t roam around places with lots of humans. They typically have dark abdomens and reddish legs, antennae, and heads, in case you want to keep an eye out.

How on Earth did this beetle feature evolve?

Funny you should ask. Some creationists like to use the bombardier beetle’s two-chamber system as an example of their theory of irreducible complexity. They insist that since the beetle’s defense mechanism wouldn’t operate without two complex parts, they could not have evolved via small modifications and are therefore a product of “intelligent design.”

Most of the creationist rhetoric masquerading as science gives an incomplete or sloppy description of the beetle’s inner workings.

In fact, a step-by-step evolution of the beetle is pretty straightforward (even if it does seem weird to us). The beetle likely developed its ability to secrete chemicals as a defense mechanism that was released via the epidermis to make it distasteful to predators. While the steps in between are all hypothetical since we didn’t see the creature evolve, the development of the beetle we know now is easily broken down into tiny evolutionary steps we’ve seen in other species.

You’ve got to wonder why a creationist would assume God created this beetle specifically to shoot chemicals out its rear end.  WTF fun facts

WTF Fun Fact 13205 – The Immortal Jellyfish

The immortal jellyfish (Turritopsis dohrnii) is a specific species of jellyfish that has the ability to revert back to its youthful, immature state after it reaches maturity. It’s a very small species that reaches a diameter of about 0.18 inches. It’s found in the Mediterranean Sea and in the waters around Japan.

This creature gets its nickname from its ability to undergo a process called transdifferentiation. This allows it to revert back into a polyp and start its life cycle over again.

Wait, seriously? There’s a jellyfish that can reincarnate itself and live forever?

Ehhh, kind of. But jellyfish don’t live their lives by the same rules that we do. Their brains and community structures don’t operate in the same ways. It’s not like their memories live on forever (that we know of).

The process of transdifferentiation in this jellyfish acts kind of like a reset button.

Turritopsis dohrnii begins life as a fertilized egg that then hatches a larva (or planula). According to the American Museum of Natural History (cited below):

“A planula swims at first, then settles on the sea floor and grows into a cylindrical colony of polyps. These ultimately spawn free-swimming, genetically identical medusae—the animals we recognize as jellyfish—which grow to adulthood in a matter of weeks.”

Anyway, during the medusa stage, the jellyfish will reproduce sexually, releasing eggs and sperm into the water. There, they will fertilize and develop into the next stage, known as a polyp. Some jellyfish species will alternate between a medusa stage and a polyp stage in their life cycle, while others will only have a medusa stage.

Here’s the key: Once the medusa reaches maturity, it can reproduce and then die, but the immortal jellyfish is able to undergo transdifferentiation, reverting back to its polyp stage, and starting the life cycle again.

The AMNH explains:

“The cellular mechanism behind it—a rare process known as transdifferentiation—is of particular interest to scientists for its potential applications in medicine. By undergoing transdifferentiation, an adult cell, one that is specialized for a particular tissue, can become an entirely different type of specialized cell. It’s an efficient way of cell recycling and an important area of study in stem cell research that could help scientists replace cells that have been damaged by disease.”

Why isn’t this a bigger deal? Can we study jellyfish to become immortal?

Undoubtedly, some billionaire has a tank full of immortal jellyfish and a geneticist at hand to try to discover that particular secret of life. But it’s important to keep in mind – again – just how different a jellyfish’s life cycle is from our own. And there’s A LOT we don’t understand about underwater creatures, which may actually hold a lot of cool secrets about life, the universe, and everything.

So, it’s important to note that it is not completely understood how or why this process of transdifferentiation occurs. It’s only unclear if these jellyfish truly can live forever or not. (I mean, what is “forever” anyway, and how do humans even measure it?)

But it is a pretty cool trick.

The immortal jellyfish is also known to be a hardy species. It can survive in a wide range of conditions, allowing it to spread and colonize new areas. Of course, there’s a downside to being hearty and potentially immortal. It’s also known to be an invasive species in many parts of the world. That means it can cause serious damage to native ecosystems. In that sense, its potential immortality is a bit of a nuisance.

In any case, the immortal jellyfish is a fascinating creature that scientists are still trying to understand.

Now, you may have noticed another fun fact which is that a mature jellyfish is often referred to as a “medusa.” The medusa is the adult, sexually reproducing stage of a jellyfish’s life cycle. The name “medusa” is taken from Greek mythology, and the jellyfish’s trailing tentacles are thought to resemble the head of Medusa. WTF fun facts

WTF Fun Fact 13201 – The Power of Looking at Cute Animals

Have you ever fallen down the rabbit hole (no pun intended) of looking at cute animals on the internet or social media? It’s hard to look away!

Well, it turns out, looking at them could be good for you.

There is evidence to suggest that your cute cat meme fixation can boost both focus and concentration. Studies have also found that looking at pictures of baby animals can improve attention and task performance.

The benefits of looking at cute animals

There is some evidence to suggest that looking at cute animals can boost both focus and concentration.

Researchers published a study in the International Journal of Environmental Research and Public Health. It found that looking at pictures of baby animals can improve attention and task performance. In fact, participants who viewed images of cute animals performed better on tasks requiring attention and fine motor skills. At least compared to those who viewed images of adult animals or inanimate objects.

Another study conducted by researchers at Hiroshima University in Japan found that looking at pictures of cute animals can increase activity in the brain’s prefrontal cortex, which is responsible for attention, problem-solving, and decision-making.

According to the Association for Psychological Science (cited below), “Led by researcher Hiroshi Nittono, the team conducted three experiments with 132 university students and concluded that cute images may facilitate improved performance on detail-oriented tasks that require concentration.”

We’ve long known that humans are attracted to looking at things that look juvenile. “Baby schema” includes things like a large head and protruding, large eyes – and they just seem “cuter” to us. Baby humans and baby animals often have these characteristics.

But now there’s proof that cute things might make our brains operate a bit better. Nittono and colleagues wrote in their paper:

“This study shows that viewing cute things improves subsequent performance in tasks that require behavioral carefulness, possibly by narrowing the breadth of attentional focus.”

Puppy power

Additionally, looking at cute animals can also release oxytocin, a hormone that is associated with feelings of love and bonding, which can lead to increased feelings of positive emotion and well-being.

It’s worth noting that these studies are still in the early stages, and more research is needed to understand the full extent of the effects of looking at cute animals on focus and concentration.

Of course, looking at cute animals is great and all, but is not a replacement for getting professional help if you have serious attention and focus issues.

WTF Fun Fact 13200 – A Group of Pugs is Called a Grumble

A group of pugs is called a grumble. Whatever you think of pugs, there’s something cute and silly about the grouping name. It’s certainly better than a “murder” of crows, right? Now those are some animals who got a raw deal.

Why a group of pugs is called a grumble

You can actually use “grumble” or “a grumbling” to refer to a group of pugs. But why?

Pugs are known for the snorting sound they make because of the shape of their nose. We suppose that sounds like a grumble.

But it’s more likely that the breed’s characteristic deep, throaty barking sounds are the grumble being referred to.

Pugs have a distinct, low-pitched bark that sounds like a growl or a grumble. Pugs are known for being very vocal and expressive.

It’s worth noting that a group of any dog breed is called a kennel, pack, or litter but different animals have different colloquial names, like a pride of lions.

How did we get pugs?

Pugs are actually an ancient breed of dogs that originate in China. They were known as “lo-sze” and were kept by the Emperors of China as lapdogs and companions.

They were also used as guard dogs and were highly valued for their loyalty and affectionate nature. Pugs were kept in the imperial palace and were considered a symbol of royalty and prestige.

Pugs were first brought to Europe in the 16th century by traders and soon became popular among the European nobility. They were particularly popular in Holland and England, where they were bred to have a shorter snout and a cocked tail.

The breed was further refined in the 18th and 19th centuries, and the modern Pug we know today was developed. Pugs were officially recognized as a breed by the American Kennel Club (AKC) in 1885.

Pugs are known for their distinctive wrinkles, short snout, and compact size, which makes them well-suited for living in small spaces. They also have friendly and playful personalities.

Pug problems

Pugs are a brachycephalic (short-nosed) breed. As a result, they’re prone to a number of health problems due to their unique facial structure.

For example, their short snout and small trachea can make it difficult for them to breathe, leading to respiratory issues or heat stroke in hot weather. In addition, they’re bulging eyes make them more likely to develop injuries, infections, and eyelid and cornea issues.

Pugs are also prone to skin fold dermatitis since the wrinkles on their faces can trap moisture and bacteria, leading to skin irritation and infection. Hip dysplasia and obesity are other risks in pugs due to their breeding.

That’s certainly something to grumble about!

However, proper care and regular vet checkups can help prevent or manage these health issues and ensure a good quality of life for a pug.  WTF fun facts

WTF Fun Fact 13188 – Geckos Turn Off Sticky Feet

People have long wondered how geckos manage to stick to the sides of structures without falling off. The short answer is that they have sticky feet. But did you know geckos turn off sticky feet when they need to run faster?

How do geckos turn off sticky feet?

Geckos use toe hairs to turn the stickiness of their feet on and off. Oregon State University (OSU) discovered the details of this mechanism in 2014. They published their results in an article that appears in the Journal of Applied Physics.

The researchers noted that the geckos’ “adhesion system mechanism” has long been a curiosity. According to Science Daily (cited below):

“‘Since the time of the ancient Greeks, people have wondered how geckos are able to stick to walls — even Archimedes is known to have pondered this problem,’ said Alex Greaney, co-author and an assistant professor of engineering at OSU. ‘It was only very recently, in 2000, that Kellar Autumn and colleagues proved unequivocally that geckos stick using van der Waals forces.'”

Geckos have a system of hairs called “seta” on their toes. The seta can bend when they come into contact with rough surfaces in order to provide points of contact that keep the sticky surface of the gecko’s toe pads from adhering. Those hairs provide millions of points of contact to allow the creatures to maneuver over terrain without sticking.

Other insects and spiders also have this adhesion system. That’s why they can stick sideways to walls, seeming to defy gravity.

The stickiness system

Greany told Science Direct: “Understanding the subtleties of the process for switching stickiness on and off is groundbreaking. By using mathematical modeling, we’ve found a simple, but ingenious, mechanism allows the gecko to switch back and forth between being sticky or not. Geckos’ feet are by default nonsticky, and this stickiness is activated through application of a small shear force. Gecko adhesion can be thought of as the opposite of friction.”

The stickiness of geckos’ feet has long fascinated scientists seeking to produce material for use in adhesives. The ability of geckos to turn off sticky feet is yet another piece of the materials science puzzle that may come in handy someday in fields like construction and robotics.  WTF fun facts

WTF Fun Fact 13182 – Peppa Pig Episode Banned in Australia

If you’re not a parent of a little one, there’s a good chance you’re not familiar with Peppa Pig. The animated show is British, aimed at preschool-aged children. It follows the adventures of a female pig and her family. Riveting stuff. But it actually does get interesting if you know that there was a Peppa Pig episode banned in Australia!

Why was a Peppa Pig episode banned in Australia?

The episode of Peppa Pig called “Mister Skinny Legs” came out in its first season, in 2004. This particular episode indicated that spiders are friendly and there’s no reason to fear them. It’s a good reminder not to be afraid of things just because they exist as “scary” in the public imagination. In fact, the episode points out that most spiders and small and can’t hurt you.

When a spider enters Peppa Pig’s room, her dad explains that there’s nothing to be afraid of and lets the little piglet pick it up and tuck it into bed with her.

This simply did not fly in Australia. You know, the place where spiders are not all small and can be very harmful.

The Guardian (cited below) revealed:

“This advice from the British-produced show was deemed to be ‘inappropriate for Australian audiences’ and the ABC banned it from future broadcast. The episode had not been broadcast on TV because of its unsuitability, but was ‘accidentally published online due to a technical problem,’ the ABC said at the time.”

They also mentioned that “Data released in January revealed 12,600 people were admitted to hospital for spider bites between 2000 and 2013.”

The second banning of Peppa Pig

When the episode aired on Nick Jr years later, parents wrote in with complaints. Nick Jr pulled the episode from the air again.

The episode is a mere 5 minutes long, but parents felt it posed enough of a danger that they didn’t want their kids encouraged to see spiders as their “friends.”  WTF fun facts

WTF Fun Fact 13179 – Military Dolphins

Dolphins’ intelligence and biological sonar make them a valuable asset to many of the world’s military organizations, including the U.S. In fact, Naval Base Kitsap uses military dolphins to protect roughly 25% of the country’s nuclear stockpile.

What are U.S. military dolphins?

The dolphins are part of the U.S. Navy Marine Mammal Program, which used dolphins for the first time during Vietnam. The details of the program are secret. But we do know that both dolphins and sea lions are trained for different types of tasks. They’re used for recovery missions, defense tasks, and mine clearing.

At Naval Base Kitsap, the dolphins protect the harbor from weapons tethered to the ocean floor or buried beneath the sediment. Their innate sonar helps them detect these objects. They’ve been trained to return to their handler with a warning signal when they find one. Even more impressive is the fact that the trainer then gives the dolphin a tool (a buoy) to mark the spot where the weapon was found. That way, passing ships can avoid it, and Navy divers can dismantle it.

And when the threat is a human diver who means harm to the base, dolphins are trained to use their mouths to attach the buoy to them, which pulls them to the surface for capture.

Washington state’s nuclear dolphin protection

According to Military.com (cited below), “Since Bangor, Washington, now houses the largest single nuclear weapons site in the world, it needs protection from all sides, including the seaward side. That’s where the Navy’s dolphin pods and sea lions come in. Navy spokesman Chris Haley says the animals have been defending the waters around the stockpile, holding roughly 25% of the United States’ 9,962 nuclear warheads, since 2010.

The former Soviet Union is believed to have trained dolphins for military purposes as well. The program is suspected to be ongoing in some sense. However, it’s also thought that much of it was sold to Iran during the fall Soviet regime.  WTF fun facts

WTF Fun Fact 13161 – Bats Give Birth Upside Down

Female bats give birth upside down and catch the baby in their wings.

Interesting facts about bats

We know bats sleep upside down, but we weren’t aware they did much else that way. And you can chalk that up to our clear lack of knowledge about anything bat-related. But thanks to Montana’s Public Radio station (cited below) and their show “Field Notes,” which is produced by the Montana Natural History Center, we now know a lot more!

For example, did you know bats only breed when it’s rainy? Or share the responsibility for nursing baby bats among colony members? Or that the “colony” is actually called a “harem”?!

It turns out that female bats are only fertile during the wet seasons. That’s January or February in the Southern Hemisphere, or March or April in the Northern Hemisphere.

They divide themselves up into harems, territorial groups with one central male bat. However, that bat doesn’t father all the bat babies. Female bats in the harem may mate with other male “harem leaders.” Interestingly, the bat experts note that “it’s very unlikely that they will mate with a non-harem male.” So any lone bats out there are out of luck.

Apparently, the smaller the bat is, the more likely he is to be successful in reproducing. That’s because the males don’t simply go around and mate with harem members at will – they have to work for it. Males have to attract females with a display of flying and hovering prowess. Big bats can’t hover as well.

According to Field Notes, “Smaller males are more successful fathers because they can maneuver more nimbly in the air. Not only can they hover well and display themselves to females, they can maneuver well during actual mating, which happens – you guessed it – upside down.”

How do bats give birth upside down?

Ok, so that’s already more upside-down time than we had imagined.

But what about birth?

Females have only one baby per pregnancy, and those babies gestate for three months. When they are ready to give birth, the mother bat hangs upside down by her feet (occasionally grasping a ceiling or branch with her hands as well). This might sound like a lot of work, but when a bat’s feet grasp something, they are actually at rest (unlike ours). So it would take more energy to be in any other position.

Eventually, the baby bat emerges feet-first and they can even grasp their mother’s fur to pull themselves out. That’s helpful!

The mother then uses her wings to ensure the baby doesn’t fall from whatever she’s hanging from.

Not only do mothers nurse babies upside down, but they even take them on hunting trips when they’re not in baby bat daycare (or small groups of young called “creches”).

The mother bats nurse their young until two weeks before they’re weaned. At this point, they may let other mother bats nurse their babies.

And a final interesting fact – female bats are favored by mothers and more likely to survive.  WTF fun facts

WTF Fun Fact 13158 – Baby Puffins

Baby puffins are called pufflings. How adorable is that?

A stranger fact about baby puffins

Ok, now that you know pufflings exist, did you know that on Iceland’s Westman Islands (aka Vestmannaeyjar), puffling season means throwing the animals off cliffs? We promise it’s not what it sounds like.

People do it to save their lives.

According to NPR:

“The chicks of Atlantic puffins, or pufflings, hatch in burrows on high sea cliffs. When they’re ready to fledge, they fly from their colony and spend several years at sea until they return to land to breed, according to Audubon Project Puffin. Pufflings have historically found the ocean by following the light of the moon… Now, city lights lead the birds astray.”

Now, some of the residents of Vestmannaeyjar “spend a few weeks in August and September collecting wayward pufflings that have crashed into town after mistaking human lights for the moon. Releasing the fledglings at the cliffs the following day sets them on the correct path.”

So they don’t chuck them off cliffs (although some may toss them less gently than need be) – they just lead them back to where they belong (or have a better chance of surviving). It’s amazing how light pollution can disrupt an ecosystem!

Puffling lives

Since a pair of puffins mates for life but only raise one egg per season, the loss of a whole generation could be devastating to their populations.

You could even get a chance to help save the pufflings if there’s a colony around you. Their seasons will depend on food supplies and light conditions.

If you decide to go on Puffin Patrol, it’s best to search for them at night with a flashlight in places where they might find food. It sounds like a great reason to go on vacation from August through September!  WTF fun facts

WTF Fun Fact 13156 – Fish Cough

Fish can cough. But they don’t sneeze. Pretty riveting stuff, right?

Well, it turns out it is pretty interesting.

How do fish cough?

While a fish can cough, it doesn’t make a sound when it does. As the experts at Fluffy Planet explain:

“Every now and then, a fish uses its gills to extract a little amount of oxygen you find in the water. Then, it releases gases like carbon dioxide. During this process, it is possible for particles or bacteria to get sucked in through the gills. Similar to how bacteria and particles are sucked into our mouth while we are breathing.

To clear the bacteria and particles, our body will either instinctively cough, or you could be prompted to cough on your own to clear out these particles. So, when these particles go into a fish’s gills, their ventilation cycle is interrupted with a cough.”

The coughs happen when the fish’s ventilation cycle is interrupted as they need to clear out their gills.

But while fish can cough, they can’t sneeze. And they don’t cry. It’s simply not biologically possible.

Why can’t fish sneeze?

We use our throats to cough, and it’s an action that clears us out. But sneezing requires air to be expelled involuntarily in response to an irritant. Sneezes expel air from the lungs at great speed. And since fish live underwater, they don’t breathe air (and don’t have a version of lungs like ours). If they did, they would float when their lungs will with air.

Now, you probably know fish don’t cry (they can’t really produce tears underwater), but you might find an article from theNew York Times interesting. It explains that researchers think fish can get depressed. When they do, they exhibit similar behavior to humans, such as isolating themselves. WTF fun facts

WTF Fun Fact 13149 – Spiders Recycle Their Webs

Not all spider webs are destroyed with a broom. In fact, spiders can recycle their webs by eating them!

How and why do spiders recycle their webs?

Some spider webs are built to last years while others only last a day or so. Of course, while those beautifully spun webs in the corner of your attic may have been built as a long-term home for the spider, in that case, their duration is influenced by how long humans allow them to stick around.

But for some neglected spider webs, they can be so enduring that a new generation of spiders might come to reside there.

More fragile webs may only last a day because spiders build them simply to catch food. Rain and pollen may affect their stickiness. In these cases, spiders will pack up a web for the day and build again the next. When this happens, spiders often eat their webs to recycle the amino acids that made up the silk protein used in web construction.

It’s an impressive feat since webs can consist of 65 feet of silk!

Not all spiders ingest their silk though. And some use it to wrap their eggs sacs. But considering how much energy it takes to weave a web, it’s not all that surprising that spiders recycle webs by eating them in some cases.

Spider web building

Spider web silk is made out of protein chains. And some of it is as strong as kevlar (though obviously it’s not as tightly woven, so we hardly notice when batting them away). In fact, scientists are studying it in the hopes of making future body armor!

Spiders typically start building webs by pulling silk from a gland in their fourth leg. The fourth leg on the opposite side contains even more silk glands. Then, in order to begin, the spider (depending on the species) can shoot it out to attach to an object or wait for a breeze to carry it to the base from which it will start building.

From there, the spider will typically create a number of attachment lines. Then they decide which are the strongest and begin weaving from there. Different spiders have different web patterns. In fact, they’re so distinct that experts can look at the structure of a web and tell you precisely which type of spider built it.

WTF Fun Fact 13131 – Queensland’s Rabbit Laws

We’ve heard of rabbit control, but Queensland’s Rabbit Laws are a bit on the strange side. For example, you cannot own a rabbit in Queensland unless you can prove you are going to display it for an acceptable purpose.

Queensland, Australia’s unique outlook on rabbits

It’s illegal to keep a rabbit as a pet in the state of Queensland. But according to the state’s business website: “…you can obtain a European rabbit (Oryctolagus cuniculus) for the purposes of exhibiting to the public. Under the Exhibited Animals Act 2015 (EAA) rabbits are category B species and may be exhibited for purposes such as educational exhibits or for entertainment.”

Those who work with rabbits much apply for a license and the premise at which the exhibition takes place needs to be licensed as well. “An example may include an invasive pest educational centre, or a zoo where the public enter the regular enclosure site to view the rabbit.”

The rules continue: “Rabbits may also be obtained solely for the purposes of exhibition outside of the premise where the licence is issued to (off the regular enclosure site). An example of activities permitted solely off the regular enclosure site include persons in the business of conducting magic performances at children’s parties.”

Queensland’s rabbit laws, continued

You must apply to exhibit a rabbit using an authorized form as well as submit a management plan detailing the way you are going to exhibit the rabbit and deal with it on a daily basis.

The management plan must address “animal welfare, human health, safety and wellbeing, social amenity, the economy and the environment…” People need to be aware of their obligations.

Why is this all such a big deal? Well, rabbits are an invasive species that Queensland has been trying to get rid of since the 1880s!  WTF fun facts

WTF Fun Fact 13128 – Panda Diplomacy

Pandas are native to China. Today, the country owns all living pandas. That’s because they’re extremely hard to breed (they simply won’t do it on their own) and any panda born outside the country becomes immediate property of China. However, the country does lease their pandas to zoos around the world in an act called panda diplomacy.

How did panda diplomacy come to be?

Between 1941 and 1984, China occasionally gifted pandas to other countries. But they stopped doing this and claimed ownership of the animals instead. Now, all pandas outside of China are technically leased (often for a decade) by the country.

Panda diplomacy is the act of gifting or leasing pandas as a gesture of goodwill.

The first panda “diplomat” came about after fashion designer Ruth Harkness took two pandas out of China and sold them to Chicago’s Brookfield Zoo and Baptist minister David Crockett Graham took and sold two to the Bronx Zoo. After that Madame Chiang Kai-shek, first lady of China and a diplomat in her own right, arranged for two more pandas to be sent to the San Diego Zoo.

However, the first act of panda diplomacy ended up buried in the news cycle since it happened during the bombing of Pearl Harbor.

Continuing diplomacy

Between 1957 and 1983, China gifted 24 pandas to 9 nations as diplomatic gestures of friendship. And when Richard Nixon visited China in 1972, he secured two more pandas from Mao Zedong for The National Zoo in Washington DC. In the first year they were on display over 1 million people came to visit the animals.

Countries around the world clamored for a chance to host the animals. But as they become more endangered, China stopped giving them away and began leasing them. In 1984, China’s leader (Deng Xiaoping) leased the first pandas to Los Angeles for the 1984 Olympics. The cost was $50,000 a month.

In 1991, the country moved to long term leases of a decade and the cost is up to $1 million a year and a promise that any cubs born will be returned to China along with their parents.  WTF fun facts

WTF Fun Fact 13127 – Group of Ferrets

Have you ever asked yourself “what is a group of ferrets called”? No doubt you’ve asked yourself this deep and probing question multiple times in the past. Or maybe not, since it’s pretty rare to run into a whole group of ferrets?

What is a group of ferrets called?

Well, in case you’re NOW wondering what the name is for a group of these furry little guys, it’s a “business.” Yes, a business of ferrets.

They may also be called a fesnyng, which isn’t nearly as catchy.

For some reason, these creatures have all sorts of names we didn’t know about. According to the website A-Z Animals (cited below), non-neutered males are called hobs, and unspayed females are called jills. For fixed ferrets, males are called gibs, and females are called sprites. Their babies are referred to as kits.

What’s this business about?

Still stuck on the fact that a group of ferrets is called a business? A-Z Animals explains (sort of):

Ferrets are known for their mischief, ability to get into things they shouldn’t, escape tactics, and energetic natures. Would it make more sense if we told you that, in the past, they were referred to as a busyness? People saw ferrets and went, ‘Wow, those are some busy critters!’”

We’ll be honest, we’ve never spent time observing ferrets, so we can’t say how busy they are.

There are some other interesting fun facts about ferrets, however. For example, it’s considered cruel to own just one since they are such social creatures. While you don’t have to get a whole business of ferrets, you should get your cuddly pal a companion. Otherwise, they can get depressed. Even if you give your pet lots of stimulation, you can’t play with them the way they need to be played with (for example, you really shouldn’t bite them, but nipping is something they enjoy doing while play-fighting either each other). They have very thick skin, so the biting doesn’t hurt them – instead, it’s something they do to communicate! WTF fun facts

WTF Fun Fact 13124 – Signalman Jack

Signalmen play integral roles in the rail industry, installing, repairing, and maintaining the signal systems used to direct trains. It’s a hard job, but in the 1880s, a signalman named James Edwin Wide taught a chacma baboon from South Africa to assist him. The baboon became known as Signalman Jack.

Training Signalman Jack

Wide had lost both legs in a work accident and needed an assistant to help him get to his job at the railroad. And apparently, he saw a baboon driving an oxcart one day on a trip to South Africa and decided he’d made a fine sidekick.

Wide named the baboon Jack and first taught him to push a small trolly to get him to his job each day a half-mile from his home. The baboon even helped with chores around the house, including sweeping and taking out the trash.

But it was when Jack followed Wide to work that he seemed to find his calling. The baboon learned to recognize the train whistles used to indicate the vehicle was about to change tracks. After watching Wide operate the signals to indicate which tracks they should take, Signalman Jack was eager to start pulling the levers himself.

Wide had no qualms about letting a baboon do his job.

Kicking back

Wide was eventually able to train Signalman Jack so well that he could sit back and pursue some hobbies while at work.

According to Mental Floss, “As the story goes, one day a posh train passenger staring out the window saw that a baboon, and not a human, was manning the gears and complained to railway authorities. Rather than fire Wide, the railway managers decided to resolve the complaint by testing the baboon’s abilities. They came away astounded.”

Eventually, the railway superintendent decided to formally hire the talented baboon. Signalman Jack was given his own employment number. He even got a salary of 20 cents a day (plus half a bottle of beer per week).

Signalman Jack worked in his job for 9 years without ever making a single error. Sadly, he died of tuberculosis in 1890.  WTF fun facts
