WTF Fun Fact 13523 – Narwhal Tusks

The narwhal is often referred to as the “unicorn of the sea.” The creature has long fascinated scientists and the public alike with its iconic spiraling tusk. However, recent research reveals that these tusks are not just ornamental; they serve as invaluable biological records.

Just like tree rings can tell us about environmental conditions, the growth rings in a narwhal’s tusk can shed light on the animal’s diet and the changes in its environment.

Studying Narwhal Tusks

An international team of scientists conducted a study by examining ten narwhal tusks obtained from Inuit hunters in northwest Greenland. The tusks, which are actually elongated canine teeth found only in males, were cut in half lengthwise to reveal their growth rings. Each ring represented one year in the life of the narwhal. By analyzing these rings, scientists could gain a unique window into the life history of these Arctic mammals.

Scientists discovered that narwhals’ diets have changed in response to the environmental changes in the Arctic. This change is partly due to the shrinking of sea ice.

They measured levels of mercury, as well as stable isotopes of carbon and nitrogen within each ring. Doing so helped them decipher the types of prey the narwhals had consumed in different years. These markers provided a snapshot of the narwhals’ diets and indicated how high their prey sat on the food chain.

The Narwhal Diet

The researchers found that until the 1990s, when the ice cover in the Arctic was still “extensive but varying,” narwhals primarily fed on sea-ice-adjacent prey like halibut and Arctic cod. However, as the ice cover started to decline between 1990 and 2000, narwhals began to consume more open ocean species. These included such species as capelin and polar cod.

These open ocean species sit lower on the food chain. This was reflected in lower mercury levels in the tusk layers for those particular years.

What’s concerning is that even though narwhals’ diets remained relatively consistent after the year 2000, mercury levels in their tusks started to rise significantly. This increase is thought to be linked to increased coal combustion emissions from southeast Asia. This revelation raises concerns about how pollutants from human activities are affecting even the most remote ecosystems on Earth.

Prof. Rune Dietz of Denmark’s Aarhus University pointed out that tusks in museums around the world represent an untapped data bank. An analysis of these could provide critical insights into how narwhals have adapted to changes over different periods and in different regions. This could lay the foundation for assessing how they are likely to cope with ongoing environmental shifts.

What We Can Learn

This study underscores the importance of understanding how climate change and human activities are affecting marine ecosystems. It shows how even seemingly unrelated things—like coal combustion in one part of the world—can have a ripple effect that impacts the diet and health of animals living in a completely different region.

Narwhal tusks serve as natural archives. They can reveal the complex interplay between marine biology, environmental change, and even global industrial activities. And they’re helping researchers stitch together a more complete understanding of the Arctic ecosystem.

WTF Fun Fact 13520 – Fish Cut Off Power

A fish cut off power to a New Jersey community. But how?

In Sayreville, Fish Cuts Off Power

On a seemingly ordinary day in Sayreville, New Jersey, a power outage caught residents off guard. The culprits behind this surprising event? An osprey and its slippery prey—a fish. The osprey’s catch fell onto a transformer’s coils, causing misalignment and, consequently, a power disruption for around 2,000 residents.

While this isn’t the first time an animal has triggered a power disruption, a fish isn’t typically a culprit. Or, in this case, we might be better off blaming the osprey for accidentally losing its meal.

Jersey Central Power & Light’s spokesperson added a touch of humor to the situation, remarking, “If you’ve ever dropped your ice-cream cone at the fair, you know the feeling,” empathizing with the osprey’s unexpected plight.

The Feathered Fiasco

Evidence pointing to an osprey’s involvement came from the puncture marks on the fish, suggesting it had been caught by the bird’s talons. It’s worth noting that ospreys, once endangered in New Jersey, have been on the rebound. Recent counts indicate 733 nesting pairs in the state. This resurgence has led utility companies, like Jersey Central Power & Light, to routinely inspect equipment for osprey nests, relocating when necessary.

The Sayreville police added a humorous touch to the incident, sketching the osprey as the “suspect” on Facebook. Alongside, they depicted the fish, now named Gilligan, behind a “police line do not cross” tape.

The playful post described Gilligan as a “hardworking family man” and urged residents not to approach the osprey, highlighting its potential “danger.”

This event underscores the need for proactive infrastructure management, considering the unforeseen challenges wildlife can present. For Sayreville residents, this story serves as a quirky tale of the day a fish cut off power and cast their town into darkness.

WTF Fun Fact 13519 – Dog Eats Passport

It’s another one of those stories: – man meets woman, man and woman plan wedding in Italy, man’s dog eats passport right before the wedding so he can’t travel. A tale as old as time, right?

For Donato Frattaroli of Massachusetts, the days after his wedding became a mad dash against time, bureaucracy, and a mischievous golden retriever named Chickie. Just days before he was set to fly to Europe for his wedding, Chickie decided to indulge in a snack that put the entire celebration in jeopardy: Frattaroli’s passport.

Chickie’s Appetite for Adventure

Anyone who has a pet knows that they can sometimes get themselves into mischief. The one-year-old golden retriever, endearingly named Chickie – short for Chicken Cutlet, took this to a new level. Multiple pages of Frattaroli’s passport, crucial for his upcoming trip to Italy, bore evidence of Chickie’s taste for international cuisine. One can only wonder if Chickie sensed the significance of the document or simply saw it as another chew toy.

Dog Eats Passport

Discovering the chewed-up passport so close to their wedding date must have been a heart-stopping moment for Frattaroli and his fiancée, Magda Mazri. The panic that would ensue in such a scenario is unimaginable for most. With a scheduled wedding reception in Italy just around the corner, every second counted.

Normally, replacing a passport can be a tedious process, often taking weeks. Undeterred, the soon-to-be-wed couple took quick action, reaching out to local lawmakers for assistance. Their pleas didn’t fall on deaf ears. Rep. Stephen Lynch and Sen. Edward Markey of Massachusetts swiftly stepped in, aiding the couple in expediting the typically lengthy passport renewal process.

A Paws-itive Spin

Optimism and perseverance paid off. Just a few days later, following a crucial appointment on Monday, Frattaroli had a brand-new passport by Wednesday, as reported by Boston ABC affiliate WCVB. A story that began with potential heartbreak had turned into a heartwarming tale of community support and swift action.

Learning from the experience, Frattaroli told WCVB about his plans to invest in a file cabinet or safe, ensuring such precious documents stay out of Chickie’s playful reach in the future.

Not ones to let a dramatic incident overshadow their joy, the couple turned the situation into a fun anecdote. They shared a celebratory photo of Frattaroli’s new passport. And in a delightful twist, Chickie wasn’t left out of the travel plans.

The golden retriever received his very own “pupster passport” – a playful nod to the chaos he unwittingly caused. This special passport boasted stamps from fun destinations such as a fire hydrant, the beach, and of course, “Granny’s home.”

A Journey of Gratitude After Dog Eats Passport

The overwhelming support and assistance the couple received in their time of need left a lasting impression. “We are extremely grateful. …All of the support has not gone unnoticed and we are forever thankful!” Mazri expressed to ABC News.

As the couple finally set off for their dream wedding in Italy, Mazri joyfully exclaimed, “Andiamo!” – “Let’s go!” in Italian.

This story, while filled with initial panic, serves as a reminder of the unpredictability of life. It’s a testament to the importance of community, resilience, and maintaining a sense of humor, even when faced with unexpected challenges.

And of course, it’s also a gentle nudge to all pet owners to keep vital documents away from their furry friends’ curious paws.

WTF Fun Fact 13516 – Bald Eagle Breaststroke


Bald eagles, like some other birds of prey, can swim using a movement that’s remarkably similar to the human breaststroke. If an eagle catches a fish that’s too heavy to lift, it may use its wings in a swimming motion to move to shore with its catch.

The Bald Eagle Breast Stroke

When one thinks of the American bald eagle, a distinctive image comes to mind: a majestic bird soaring high in the skies, its sharp eyes scouting below for prey, or perched high atop a tree or cliff. Rarely do we picture this iconic bird swimming in water, wings sprawled out, making its way steadily to the shore.

However, bald eagles are primarily fish eaters, and their hunting strategy involves swooping down from a high perch or mid-air to snatch fish out of the water with their talons. Sometimes the prey might be too hefty for the eagle to lift.

Instead of abandoning the catch, the eagle, driven by instinct and determination, will resort to “swimming” to the nearest shore, using its wings in a motion reminiscent of the human breaststroke.

The Mechanics of the Eagle’s “Breaststroke”

Eagles, like all birds, have powerful pectoral muscles that control their wing movements. When airborne, these muscles allow them to achieve strong, sustained flapping or to glide gracefully using updrafts. In the water, these same muscles serve a different but equally vital purpose.

An eagle in the water will spread its wings out and push against the water, essentially using its wings as makeshift paddles. This motion propels the bird forward in a slow but steady manner. The movement is surprisingly coordinated, and the resemblance to the human breaststroke is uncanny. The eagle keeps its head above water, looks straight ahead, and aims for the shore.

Swimming is not an eagle’s forte, so the bald eagle breaststroke is not something you’re likely to see.

The process is energy-intensive and leaves the bird vulnerable to potential threats. The waterlogged feathers become heavy, making the task even more arduous.

However, the promise of a big meal may outweigh the risks, especially during breeding season when there are eaglets to feed. A large fish can provide sustenance for the entire family.

While the image of a bald eagle swimming might seem incongruous, it’s a vivid reminder of the surprising and often overlooked behaviors of the animal kingdom. Nature is full of examples of adaptability and resilience, and the bald eagle’s occasional foray into aquatic locomotion is a fascinating instance of this.

WTF Fun Fact 13508 – Mamenchisaurus sinocanadorum

If you know a kid obsessed with dinosaurs, you may have heard of Mamenchisaurus sinocanadorum. If not, you should let that kid know about this creature immediately because it’s pretty cool.

The Discovery and Classification of Mamenchisaurus sinocanadorum

When we think of the most impressive creatures that ever roamed the Earth, our minds often dart to the giants of the Mesozoic Era – the mighty dinosaurs. Among these behemoths, one dinosaur stands out for the astounding length of just one part of its anatomy: its neck.

Meet the Mamenchisaurus sinocanadorum, a species of dinosaur that boasted a neck almost 50 feet long. That’s a neck six times longer than that of today’s tallest land animal, the giraffe!

Mamenchisaurus sinocanadorum belongs to a group of dinosaurs called the sauropods. They are recognized by their long necks, long tails, and massive bodies supported by four thick, pillar-like legs. Although several sauropods had impressively long necks, the Mamenchisaurus goes well beyond the rest!

The species was unearthed in China and was a significant find for paleontologists. These findings provided more information about the diverse world of sauropods and the different evolutionary paths they might have taken.

A Neck to Marvel At

At nearly 50 feet long, the neck of Mamenchisaurus sinocanadorum was a true wonder of nature. To put it into perspective, that’s longer than a school bus and almost as long as a bowling lane! But what evolutionary benefits did such a lengthy neck provide?

Foraging Strategy
With such an extended reach, this dinosaur could access food sources that were out of reach for other herbivores. This reduced the competition for food. It also allowed the creature to graze over a larger area without having to move its massive body frequently.

Cooling Mechanism
Some theories suggest that a long neck could have served as a cooling mechanism. The large surface area could have helped dissipate heat. This may have been vital for such massive creatures that might have struggled to maintain an optimal body temperature.

Display and Mating
In the animal kingdom, impressive physical features often play a role in mating displays. Though speculative, it’s possible that longer necks might have been seen as more attractive or dominant. This would help individuals with longer necks secure a mate.

The Anatomy Behind the Length

The length and weight of such a neck would require robust support and respiratory systems. Vertebrae would have been elongated and possibly hollowed in sections to reduce weight. Air sacs might have been present to aid in breathing, similar to modern birds. The neck’s muscle and tendon structure would also need to be incredibly strong. But it would also have to be flexible to support and maneuver this impressive length.

Comparing Mamenchisaurus sinocanadorum to the Modern Giraffe

Modern-day giraffe necks measure approximately 8 feet in length and pale in comparison to the neck of the Mamenchisaurus sinocanadorum. However, both animals show that evolution can lead to some astounding anatomical features when they provide an advantage.

It’s intriguing to imagine how these two creatures, separated by millions of years, navigated their habitats with such long necks.

WTF Fun Fact 13503 – Antarctic Feather Star

In the dark waters of the Antarctic, an unknown “sea monster” with an astonishing 20 arms recently emerged – the Antarctic feather star. The researchers had this specimen on ice for years after a near-decade-long expedition during which they collected samples. Only in 2023 did they uncover the latest creature from the deep.

The Antarctic Expedition

This journey into the Antarctic waters spanned almost a decade, from 2008 to 2017. Its primary objective was to study elusive or cryptic sea creatures, especially those belonging to the genus Promachocrinus – commonly referred to as Antarctic feather stars.

While Antarctic Feather Stars bear similarities to starfish and sea cucumbers, they possess a distinct otherworldly appearance, notably when swimming. Their movement, combined with their considerable size, sets them apart in the marine world.

These creatures reside in varying depths, from a relatively shallow 65 feet to an astounding 6,500 feet beneath the waves.

Eight unique species were identified during the expeditions, with half being entirely novel to science. Earlier, only Promachocrinus kerguelensis was unmistakably linked to this genus. A combination of DNA analysis and physical morphology studies led to these recent classifications.

The Strawberry Feather Star

Named Promachocrinus fragarius, this particular discovery stands out. Its body, curiously enough, resembles a strawberry and showcases a range of colors from muted purples to rich reds.

Boasting a staggering 20 arms, this “sea monster” is unlike any other in its category.

The vast number of arms, each intricately designed, adds to its otherworldly presence, particularly when the creature is in motion. When swimming, the feather star presents an ethereal dance in the deep sea, making it a sight to behold.

Unlike other invertebrate ocean animals, the Antarctic Strawberry Feather Star stands out both due to its substantial size and its unique appearance, which is reminiscent of the delicate feathers of a bird, but with a marine twist.

Its habitat in the frozen depths of Antarctica makes its discovery particularly fascinating. Antarctica’s waters are among the least explored due to their harsh and inaccessible nature, making every discovery from this region a notable contribution to marine biology.

The Antarctic Strawberry Feather Star offers a glimpse into the rich biodiversity of our oceans, reminding us of the endless mysteries that lie beneath the waves, waiting to be discovered.

WTF Fun Fact 13496 – Parachuting Beavers

Conservation strategies can take on a wide variety of shapes and forms – sometimes they’re scientific breakthroughs or well-planned reintroduction programs; and other times, they are, well, parachuting beavers.

Yes, you read that right.

During the 1950s, in one of the most peculiar conservation efforts, beavers in Idaho were parachuted from planes to aid in repopulation efforts. Here’s the fascinating story.

The Problem: Beaver Overpopulation

Post World War II, Idaho faced a conundrum. With the growth of human settlements and the rise in agriculture, the state found that some regions had an overpopulation of beavers.

These industrious animals, known for their dam-building abilities, often clashed with human development. Their dams would flood roads and farmland, creating challenges for the human inhabitants of the area.

At the same time, other remote regions of Idaho suffered from a lack of beavers.

Historically, beavers played a pivotal role in these ecosystems, creating wetlands that benefited various forms of wildlife. Without them, these ecosystems began to degrade.

The Solution: Aerial Beaver Relocation

To address this imbalance, the Idaho Department of Fish and Game (IDFG) devised a novel solution. Why not relocate the beavers to the regions where they were needed?

But there was a hitch. Many of these areas were so remote that traditional methods of transportation were unfeasible.

Enter Geronimo, the beaver that would pave the way for a unique conservation strategy. As a test subject, Geronimo took several flights, gently floating down via parachute to ensure the safety of the process. After repeated tests (and presumed beaver approval), the IDFG decided to move forward with their parachuting beaver operation.

Operation Beaver Drop: Parachuting Beavers into Idaho

The process was relatively straightforward, albeit unorthodox. Beavers were trapped in overpopulated areas, placed inside protective boxes, and attached to parachutes. An airplane would then fly over the designated release area, and these furry engineers would descend to their new homes.

Between 1948 and 1950, this project saw the successful relocation of over 70 beavers. The majority of them adapted quickly to their new environments, immediately setting to work building dams and establishing new colonies.

The parachuting beaver strategy, despite its odd nature, was deemed a significant success. The relocated beavers transformed the landscapes, aiding in the creation of wetlands and benefiting countless other species in the process. Birds, fish, and mammals found better habitats thanks to the beaver’s natural dam-building tendencies.

Other states didn’t adopt the parachuting strategy (due in part to the development of better transportation methods and roads). But it showcased the lengths to which conservationists were willing to go to ensure the survival and prosperity of a species.

Revisiting the Tale of Parachuting Beavers

For many years, the tale of Idaho’s parachuting beavers was considered an exaggerated myth of the West. That was until 2015, when a film from the IDFG archives was rediscovered. This film, titled “Fur for the Future,” documented the entire process, turning local legend into verifiable history.

Suddenly, a story that sounded like a tall tale had evidence to back it up, and it captured the imagination of people worldwide.

WTF Fun Fact 13489 – Most Orangutans are Left Handed

If you’re a lefty, you have more in common with an orangutan than just 97% of your DNA since most orangutans are left-handed too. One neuroscientist, Bill Hopkins, said his research showed around 66% of orangutans to be lefties.

Studying Handedness in Orangutans

Curiosity sparked the investigation into orangutan handedness. Scientists found themselves wondering – do these creatures prefer one hand over the other, like us humans? It’s something we’ve all thought about, right? No? Ok, well anyway.

Researchers observed orangutans in their natural and semi-natural habitats. Hopkins appears to be the only one who suggested the specific 66% number. But plenty of other research has found that while some primates like chimpanzees and bonobos (our closest relatives) tend to be right-hand dominant, gorillas and orangutans are not.

What Does it Mean that Most Orangutans are Left-Handed?

Just like in humans, an orangutan’s hand preference comes from the brain. We call it “cerebral lateralization” – a fancy term for one side of the brain being bossier than the other.

The left hemisphere controls right-handedness, and the right hemisphere oversees left-handedness. Both genes and environment play a part in this.

But a mystery remains. Why do orangutans tend to be left-handed more often when compared to humans and other great apes?

Out in the wild, being left-handed doesn’t make the orangutans any less skillful. They foraged for food, made comfy nests, and swung from tree to tree with aplomb. Whether peeling fruit or brachiating through the forest, left-handed orangutans showed no signs of struggle.

Now here’s an intriguing question. We humans share 97% of our DNA with orangutans, so why aren’t more of us left-handed? Researchers are keen on finding an answer. They hope to understand how and why hand preference might have shifted during human evolution.

Orangutans, like us, are social animals. They have a rich array of communication methods at their disposal. This research is igniting interest in the connection between left-handedness and communication. Also, it has made scientists curious about the potential link between hand preference and cognitive abilities.

A Curious Conclusion

The higher percentage of left-handedness in orangutans adds an exciting twist to our understanding of these creatures. It opens up a new avenue for exploration: Why this hand preference? How does it affect their survival, adaptation, and mental prowess?

Researchers are now actively trying to link left-handedness to the species’ behavior and neural traits. They’re also excited to understand how this discovery could shape our understanding of human evolution.

WTF Fun Fact 13483 – Lifespan of a Cat Increasing

The average lifespan of a cat (well, an indoor cat) is around 12 to 15 years, but many cats now can live to be 20. These numbers seem to be trending upward. (Although we have to admit that we haven’t seen this confirmed by researchers anywhere – the evidence appears to be anecdotal).

Factors Influencing the Lifespan of a Cat

Today’s cats appear to be living longer, healthier lives. This is aided by advancements in veterinary medicine and growing awareness about the importance of preventive care.

From lifestyle choices to genetics, every aspect has an influence on how long our fur-buddies can thrive. The following are some of the most significant contributors:

Indoor Versus Outdoor Cats

Like humans, cats’ lifestyles profoundly affect their longevity. It’s no secret that indoor cats tend to live longer than their outdoor counterparts. They are shielded from various risks like diseases, accidents, predators, and harsh weather

The protected environment ensures they enjoy a higher average lifespan, usually about 15-20 years. In stark contrast, outdoor cats face myriad threats that can often cut their lifespan to just 2-5 years.

Preventive Care

Preventive care, like routine check-ups, vaccinations, and flea and tick preventatives, plays a key role in cat longevity. Regular veterinary examinations can help detect potential health problems early, improving the odds of successful treatment.

Early diagnosis and treatment can be life-saving, especially for chronic conditions like kidney disease, common in cats.

Diet and Weight Management

Another significant factor influencing cat lifespan is diet and weight management. Proper nutrition is crucial for the overall well-being of cats. A balanced diet containing all necessary nutrients contributes to longevity.

On the other hand, obesity is a severe issue that can lead to various health problems like diabetes, arthritis, and heart diseases, reducing a cat’s lifespan.

This is starting to sound a lot like people…or any other living thing, really. Don’t play in the road, eat healthy, get exercise, see a doctor when you’re sick…

Genetics and Breeds

Genetics and specific breed characteristics can influence how long a cat lives.

Some breeds are prone to specific health conditions that can affect their lifespan, while others are generally known for their longevity. For instance, Siamese and Maine Coon cats often live well into their teens, with many reaching their early 20s.

The Lifespan of the Oldest Cat

Now, all of this talk of health might have you thinking that it’s the only way to live a healthy life. But let’s think about humans for a moment. Ever read an interview with someone over 100 who insists the secret is bacon or cigarettes or something? Some of this is just random.

The oldest cat on record, Creme Puff, was well-cared for though. She was an astonishing 38 years and 3 days at her death. Her owner also owned the previous oldest living cat! The secret? Some things you really aren’t supposed to give a cat – like caffeine. The diet fed to these cats was largely commercial cat food with some eggs, turkey bacon, broccoli, coffee with creme, and an eye dropper of ref wine every two days!

Don’t try that at home, but maybe do take the owner’s advice to play with your cat as much as possible if you want them to live a long and active life.
