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 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.
