WTF Fun Fact 13301 – Cat Whiskers are Sense Organs

Cat whiskers are not just ordinary hairs. Also known as vibrissae, they are thicker, longer, and more deeply embedded in the skin than regular fur. They are also richly supplied with nerve endings and blood vessels, allowing cats to use them as specialized sense organs. Cat whiskers can also be present on the front legs, above the eyes, and on the back of the hind legs. These whiskers play an important role in helping cats navigate and sense their environment.

Whiskers galore

Cats can have whiskers on their legs, specifically on the front legs. These whiskers are called carpal whiskers or wrist whiskers and are located on the underside of the wrists. They also help cats navigate their environment and detect potential prey or obstacles.

Cats even have whiskers above the eyes, on the cheeks, and on the back of the hind legs. These whiskers are known as supraorbital, genal, and tarsal whiskers, respectively. These whiskers are less prominent than the ones on a cat’s face, but they still play a role in helping the cat to sense its surroundings.

More facts about cat whiskers

Cat whiskers are not all the same length. They vary in length and thickness depending on their location on the cat’s body.

Cats can also move their whiskers independently of their body movements. This allows them to sense their surroundings in a very precise way.

No doubt you’ve seen cats climb into some small and unlikely places. Well, whiskers can help cats determine if they can fit through tight spaces. If their whiskers can fit through a gap, then they know their entire body can fit through as well.

And did you know that when cats are hunting, they will point their whiskers forward to help them focus on their prey. On the other hand, if a cat is feeling threatened or fearful, it will flatten its whiskers against its face, making them appear smaller and less noticeable to potential predators.

Who knew there was so much more to know about cat whiskers?

WTF Fun Fact 13276 – Hallucigenia

If you’re a fan of bizarre creatures that once roamed the Earth, then Hallucigenia is probably right up your alley. This ancient invertebrate still confounds scientists today with its appearance and mysterious origins. The Hallucigenia lived during the Cambrian period. That’s about 515 to 500 million years ago.

What’s in a name?

We derive its name from its strange anatomy and shape. At the front of its body, it has a pair of tentacles. Next, its long, narrow body was covered in spines and spikes – likely for protection against predators rather than to simply make it look cool.

It also had seven pairs of legs, each with multiple spikes, and a pair of spiky protrusions on its head.

The Hallucigenia’s body ended in a pair of hooks, and it had a thin, flexible skin that may have been used for gliding or swimming. It’s definitely not something you’d want to hug.

With its long spines, claw-like appendages, and worm-like body, some have dubbed it a “nightmare creature.” Scientists are puzzled by this unique anatomy since the creature is not built like animals on Earth today.

Hallucigenia loco-motion

You might think because it has legs that it “walks.” But no, it moves in the creepiest way possible.

Instead of walking or crawling on the ground, the Hallucigenia used its long spines to travel across the sea floor. We call this type of locomotion “arm-leggedness,” and we see it in very few creatures today.

Scientists believe that the Hallucigenia was a simple, bottom-dwelling creature that likely lived in shallow seas. Its long, tubular body could have been an advantage to burrow into the sediment or to probe for food.

Researchers once thought it was a primitive crab, but it is not included in the group called Lobopodia since it’s more likely that it’s an early offshoot of a group of animals called Panarthropoda. This would make it an evolutionary “cousin” of modern-day arthropods such as spiders and insects.

Hallucingenia and the fossil record

The fossil record of Hallucigenia serves as a window into the Earth’s past. It provides a glimpse into how our planet’s ecosystems and organisms have evolved over millions of years. And as researchers continue to make new discoveries, it will be interesting to see how scientists piece together the puzzle of this strange creature and learn more about its story.

It might not be the cuddliest creature in history, but the Hallucingenia is no hallucination. It’s one of the planet’s fascinating mysteries born in a time when nothing like a human existed. The Cambrian period saw an explosion in the evolution of new types of creatures. And we know a lot about it because there were many hard-bodied creatures that got preserved in the fossil records (as opposed to being smashed into goo).

Humans would eventually evolve from the first vertebrates (creatures with a backbone) that emerged during this time. But that was going to take tens of millions more years.

WTF Fun Fact 13275 – The Hyrax

The hyrax looks like a rodent. But, in fact, it’s actually more closely related to elephants, despite its small size and rodent-like appearance. This surprising relationship is due to similarities in their teeth and skull structures, as well as genetic evidence.

Fun facts about the hyrax

This is one odd little animal!

Hyraxes are also known as dassies or rock rabbits. These little creatures are furry mammals native to Africa and the Middle East. Hyraxes belong to the order Hyracoidea and are found in rocky habitats, such as mountains and cliffs.

There are four species of hyraxes: the rock hyrax, the bush hyrax, the yellow-spotted hyrax, and the tree hyrax. The rock hyrax is the most common and can be found in many parts of Africa.

Hyraxes are social animals that live in groups of up to 80. They communicate with each other through a series of grunts, whistles, and screams (so charming!).

They’re also territorial and mark their territory with unique specialized scent glands located on their feet. The cute little herbivores feed on a variety of vegetation, including leaves, shoots, and bark.

Hyraxes are also known for their excellent sense of hearing and sight. This helps them detect predators such as eagles, leopards, and snakes. When threatened, the animals really know how to make a racket. They will emit a loud, high-pitched scream to alert the rest of the group. (We’re getting increasingly grateful these don’t live in our backyard.)

Turning animals into oil?!

Hyrax oil, also known as rock rabbit oil or dassie oil, is a type of oil that is extracted from the fatty tissues of hyraxes. It has been used for a variety of purposes, including in traditional medicine, as a fuel source, and for cosmetic and perfume production.

Historically, this oil has been used in traditional medicine to treat various ailments, such as skin conditions, ear infections, and rheumatism. It has also been used as a lubricant and fuel source for lamps and candles.

In some cultures, hyrax oil has also been used in cosmetics and perfumes due to its distinctive musky odor. However, the use of their oil in modern cosmetic and perfume production is not common, and synthetic musk fragrances have largely replaced it.

Despite its historical use in traditional medicine and other industries, the harvesting of hyrax oil is considered illegal in many countries due to the endangered status of some hyrax species. As a result, it has largely fallen out of favor in modern times.

WTF Fun Fact 13264 – Duck Have Waterproof Feathers

Did you know that ducks have highly waterproof feathers? It makes sense, right? After all, they’d probably freeze in cold weather if something wasn’t helping to insulate them.

How do waterproof feathers work?

A duck’s waterproof feathers are due to the special oil that they produce.

Ducks have a special oil gland called the preen gland (also known as the uropygial gland) that is located at the base of their tail. They spread the oil over their feathers as they preen themselves.

This oil also keeps the duck’s feathers dry and helps it to float in water. And to top it off, it even contains antimicrobial properties that help to keep the duck’s feathers clean and free from harmful bacteria.

Duck feathers also trap air and provide insulation to keep them warm in cold water. And they have a unique structure that helps to repel water.

The feather shaft is made up of a hard, central quill surrounded by a series of barbs and barbules that interlock to create a flat surface. These barbs and barbules are arranged in a particular way that allows them to lock together tightly. This creates a barrier that prevents water from penetrating through the feather to the bird’s skin.

This unique feather structure is what allows ducks to stay warm and dry in wet environments and helps them to regulate their body temperature.

The beauty of duck feathers

Duck feathers aren’t just practical. They’re also beautiful in ways that humans can’t even see. Their colors aren’t always visible to the human eye.

Many duck feathers contain iridescent structural colors that are created by the way that light reflects off of the feather’s surface. This can create a range of different colors and patterns, from bright greens and blues to deep purples and reds.

Male ducks often have brightly colored feathers that are used to attract mates during the breeding season. For example, male mallards have distinctive green heads and necks, while male wood ducks have a colorful pattern of red, green, and white feathers on their faces and bodies. — WTF fun facts

WTF Fun Fact 13256 – Sallie Ann Jarrett

A Staffordshire Bull Terrier named Sallie Ann Jarrett was one of the most famous American Civil War mascots. She belonged to the 11th Pennsylvania Volunteer Infantry Regiment of the Union Army.

After the war, a statue was erected in her honor at the Gettysburg Battlefield.

What’s the story of Sallie Ann Jarrett?

During the American Civil War, animals played an important role in military life. They provided companionship, and morale-boosting in addition to serving as mascots.

Sallie belonged to the 11th Pennsylvania Volunteer Infantry Regiment of the Union Army. She was adopted by the soldiers as a puppy and became a beloved member of the regiment. Sallie was known for her fierce loyalty to her human companions and her bravery in battle.

Sallie accompanied the regiment on many of its campaigns and was present at some of the most significant battles of the war. This included the Battle of Gettysburg.

At Gettysburg, soldiers reported seeing Sallie standing guard over the bodies of the fallen, refusing to leave their side. Sallie got a leg wound in the battle, but she survived. Afterwards, Sallie continued to serve as their mascot until the end of the war.

Honoring a mascot’s legacy

After the war, the 11th Pennsylvania erected a monument in honor of Sallie at Gettysburg. It’s now a popular tourist attraction and a symbol of the role that animals played in the Civil War.

In addition to the statue, there are many stories and legends about Sallie’s exploits during the war. One story claims that she was present at the surrender of Confederate General Robert E. Lee at Appomattox Courthouse. Storytellers claimed that she barked so loudly that Lee himself heard her. Another story claims that she once saved a Union soldier from drowning by jumping into a river and pulling him to safety.

While some of these stories may be exaggerated or apocryphal, they are a testament to the enduring popularity of Sallie.

WTF Fun Fact 13255 – The Unicorn Throne

In the mid-16th century, a German merchant sold what he claimed was a unicorn horn to King Frederick II of Denmark for a large sum of money. The “unicorn horn” was later found to be a narwhal tusk. At the time, the tusk was even used to create a “unicorn throne.” That throne is still on display at Rosenborg Castle in Copenhagen, Denmark today.

What’s the story behind the horn?

The story of the Unicorn Throne begins in the mid-16th century when a German merchant sold what he claimed was a unicorn horn to King Frederick II of Denmark. At the time, many people believed that unicorns were real animals and that their horns had magical healing powers.

King Frederick II was so impressed with the “unicorn horn” that he had it mounted in a gold and silver frame and displayed in his cabinet of curiosities. The cabinet was known as the “Kunstkammer,” and it contained a wide variety of objects, including natural specimens, scientific instruments, works of art, and oddities from around the world.

How did the narwhal horn become part of the “unicorn throne”?

Over a century later, King Frederick III commissioned a new throne for the coronation of his son, Christian V. A master craftsman named Bendix Grodtschilling was tasked with creating it. He spent several years working on the throne, which would eventually become known as the “Unicorn Throne.”

The throne is made from 250 kilos of silver and is covered in intricate carvings and symbols. The most striking feature of the throne is the backrest. This is decorated with three life-size silver lions and is topped by a large silver crown. The armrests are adorned with carved figures of the virtues and vices, while the seat is covered in red velvet.

But the most important feature of the Unicorn Throne is the narwhal tusk that runs down the center of the backrest. This tusk is over 2 meters long. It is believed to be the same one that was sold to King Frederick II as a “unicorn horn” over a century earlier. The narwhal tusk is surrounded by silver branches and leaves, with a silver unicorn perched on top of it.

The Unicorn Throne was used for the coronation of King Christian V in 1671. It was last used for a coronation in 1840, during the coronation of King Christian VIII of Denmark.

The Unicorn Throne has also become an important symbol of Danish royal power and prestige. And today, it’s recognized as one of the most impressive pieces of furniture in Europe.

The Unicorn Throne is on display at Rosenborg Castle in Copenhagen, Denmark.

WTF Fun Fact 13251 – Playing Possum

Maybe you’ve heard the phrase “playing possum,” and perhaps you even know that opossums “play dead” when faced with a dangerous situation. But here’s an interesting animal fact: Did you know that, when threatened, opossums actually go into a comatose state that can last for several hours?

During this time, they appear to be dead, lying motionless with their eyes closed and tongues hanging out of their mouth. They also emit a foul-smelling fluid from their anus, which can deter some predators.

They aren’t just playing around!

(Oh, and Americans often use possum and opossum interchangeably even though “possums” are the Australian version of the marsupial.)

What’s the point of possums playing dead?

One theory is that playing dead (or playing possum) is an instinctual defense mechanism. This may have evolved to protect the tiny creatures from their larger predators who don’t really want a dead meal. Not many animals (that aren’t sick) want to eat dead creatures since decomposition can be hazardous to health.

In this case, the opossum’s best chance of survival would be to make themselves unpalatable to their attacker by appearing dead. The opossums that learned to play dead survived to reproduce and teach their young the trick, while those who tried to run had less chance of survival and reproduction.

Playing dead may also allow opossums to avoid confrontation (don’t try this at home). It may be the case that by lying motionless, they convince their potential attacker they’re not a threat worth pursuing.

Death is not a choice

It’s important to note that the possums that play dead do not actively choose to do so. This is an instinctual behavior that can automatically happen when they’re overwhelmed. In these situations, the opossum’s natural response is to go into a state of shock and “play dead” as a last resort to survive.

During this state, the opossum’s heart rate and breathing slow down, and it becomes unresponsive to external stimuli. The body also produces a foul-smelling liquid that makes it unappetizing to predators. The opossum may also release a small amount of fecal matter, adding to the illusion that it is dead.

The biological advantage

There are also biological advantages to looking dead. When a possum plays dead for any significant length of time, it’s conserving energy in addition to avoiding injury. By going into a comatose state, they may be able to reduce their metabolic rate and lower their body temperature, which can help them conserve energy.

This may be particularly important for opossums that live in harsh environments where resources are limited or predators are abundant. You need every ounce of energy you can get just to stay alive.

Do all possums engage in this behavior?

Interestingly, no. Not all opossums play dead.

While it is a common defense mechanism among opossums, some individuals retain the ability to flee or fight back when threatened.

The decision of which response to use is not a conscious one but is determined by a complex set of factors, such as the type of threat, the possum’s physical condition, and the environmental conditions.

WTF Fun Fact 13247 – The Fish with a Unicorn Horn

Scientists in China have discovered a new species of fish with a unicorn horn. Named “Sinocyclocheilus longicornus,” the lives in pitch-black caves, has no scales, tiny eyes that are likely non-functional, and a unicorn-like horn sticking out of its head.

What’s the story behind the fish with the unicorn horn?

Scientists discovered the fish in a remote cave system in Guizhou Province in southwestern China. The discovery was made by a team of scientists led by Dr. Meng Wu of the Chinese Academy of Sciences, who specialize in studying subterranean life forms.

Sinocyclocheilus longicornus is a type of cave fish, which means it has adapted to living in a dark, aquatic environment without any access to sunlight. Like other cave fish, Sinocyclocheilus longicornus has evolved certain physical traits to help it survive in this challenging habitat. For example, it lacks developed eyes and pigmentation, since these features are not necessary in a pitch-black cave.

However, it’s the “unicorn horn” made of bony tissue that’s stirring up curiosity. Scientists believe the fish use the horn for fighting or as a way to sense their environment.

Why is this discovery important?

The discovery of Sinocyclocheilus longicornus is just one example of the ongoing research into subterranean life forms and the unique adaptations that allow them to thrive in the dark, hidden corners of the world. As scientists continue to study these organisms, we may gain new insights into the evolution of life on Earth and the incredible resilience of living things in the face of extreme environmental conditions.

Furthermore, the discovery of a new species of cave fish is particularly exciting for scientists. It highlights how much we still have to discover about life on Earth. Despite centuries of exploration and research, there are still many corners of the planet that remain largely unexplored. This is particularly true of the deep, dark recesses of the world’s caves and other subterranean environments.

Finally, the discovery of Sinocyclocheilus longicornus serves as a reminder of the importance of protecting these unique and fragile ecosystems. Caves and other subterranean environments are home to a wealth of unique species that are found nowhere else on Earth. Mining, tourism, and other human activities can disrupt the delicate balance of these ecosystems. The result is irreparable harm to the species that live there. — WTF fun facts

WTF Fun Fact 13243 – Missing Dog Returns To Shelter

A dog that went missing from its new home in Texas walked 10 miles to her former shelter and rang the doorbell. The story was reported by the Animal Rescue League of El Paso. The shelter has doorbell camera footage of the dog named Bailey returning to the shelter two days after she went missing in late January 2023.

Missing dog returns “home”

Loretta Hyde, founder of Animal Rescue League of El Paso, told USA Today (cited below) that “A family had adopted the friendly husky mix from the Animal Rescue League of El Paso last month. At some point soon after, Bailey got loose and ended up running away.”

The shelter put the call out on Facebook for local residents to keep an eye out for Bailey. While there were a few sightings, no one was able to catch her.

Luckily, Bailey knew the way back to safety. She just didn’t seem to know the way back to her new home.

After spending two days missing, the El Paso shelter doorbell camera activated and alerted workers to a 1am visitor on January 31. It was Bailey – and she had walked 10 miles to get to where she thought was “home.”

She was safe and unharmed, but very hungry after going a few days without food.

“I’ll be darn, at 1:42 in the morning she’s ringing the doorbell like, ‘I’m home,‘” Hyde told USA Today. “The Ring camera kept going off and off and off … and you’ll see in the video that she’s running out there, sitting, waiting for somebody to come.”

One one of the shelter’s workers was able to talk to the dog through the camera. She called Bailey’s name and the pup “booped” the camera.

Return to sender

Bailey took a day to sleep off her big adventure and make up for lost calories at the shelter.

It appears Bailey went missing under innocent circumstances. Her new owner had been up for days searching for her and had even stayed out all night when she first went missing. They contacted the shelter immediately for help.

Bailey was happily reunited with her new family after getting a checkup, and everyone was grateful for the happy ending. — WTF fun facts
