WTF Fun Fact 13508 – Mamenchisaurus sinocanadorum

by

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

by

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

by

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

by

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

by

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.

WTF Fun Fact 13478 – Dolphins May Use Parentese Voice

by

Do dolphin moms use baby talk, also known as a parentese voice? It’s hard to know for sure, but researchers think this might be the case.

What is a parentese voice?

Just like humans resort to baby talk when interacting with infants, bottlenose dolphins employ similar tactics. Studies indicate that bottlenose dolphin mothers alter their whistle pitches in the presence of their calves. This behavioral adjustment, often termed “parentese,” is thought to enhance calf attention, promoting bonding and facilitating vocal learning.

Every common bottlenose dolphin (Tursiops truncatus) establishes a unique whistle within the initial months of its existence. These distinctive whistles function as names, enabling dolphins to identify and keep track of each other in the vast waters, explains Laela Sayigh (in the article cited below), a marine biologist at the Massachusetts-based Woods Hole Oceanographic Institution.

However, interestingly, dolphin mothers seem to modify their whistles when interacting with their young ones. These calves typically stay with their mothers for three to six years, allowing ample opportunity for communication.

Sayigh initially noticed this modulation in motherly dolphin tunes during a 2009 study conducted by one of her students. The research didn’t delve deeper into this observation at the time. Recently, Sayigh and her colleagues revisited this phenomenon, analyzing signature whistles from 19 female dolphins, both in the presence and absence of their calves.

This study focused on a wild dolphin population residing near Sarasota Bay, Florida, a community that has been under scientific observation for over five decades. The scientists scrutinized 40 instances of each dolphin’s signature whistle, half of which were vocalized when their calf was nearby.

Analyzing the Dolphin Parentese Voice

The research unveiled that the mother dolphins employed a broader pitch range when their young ones were around. On average, the highest pitch was slightly higher, and the lowest pitch somewhat lower than when the calves were absent. These changes strikingly mirror the characteristics of human baby talk, claims Sayigh.

A comparison between dolphin whistles in the presence and absence of calves illustrates the pronounced change in pitch. Much like human caregivers, who use real words but distinct inflections while interacting with babies, dolphins too exhibited higher pitches and a broader pitch range.

Studying Dolphin Communication

Despite these intriguing findings, some researchers like Quincy Gibson, director of dolphin research at the University of North Florida in Jacksonville, caution that the study’s observations were made during catch-and-release situations. For a comprehensive understanding of dolphin communication, it’s crucial to observe and listen to freely swimming dolphin mothers, she suggests.

Mauricio Cantor, who studies animal behavior at Oregon State University’s Marine Mammal Institute, points out the speculative nature of attributing similar roles of ‘parentese’ in humans and dolphins. Absolute certainty in this matter is unachievable until we can understand dolphins’ actual intentions behind these actions, he argues.

Nevertheless, Sayigh contends that it’s fascinating to witness potential similarities in how different species communicate with their infants. This study paves the way for further exploration into the intricate world of dolphin communication.

WTF Fun Fact 13477 – The Sonoran Desert Toad

by

When it comes to the world of psychedelic fauna, few species are as intriguing as the Sonoran Desert toad. It’s technically known as Incilius alvarius. But licking the toad won’t get you high – instead, it might kill you.

Don’t Lick The Toads

Last fall, a plea from the U.S. National Park Service urged visitors to abstain from licking this particular species. The reason? A potent psychedelic compound excreted through its skin has led to increasing instances of poaching, over-harvesting, and illegal trafficking.

Despite the warnings, the toad’s secretions don’t typically induce psychedelic experiences when ingested directly. In fact, they’re toxic when ingested and could lead to cardiac arrest.

When the secretions are collected, dried, and smoked, however, they may elicit auditory and visual hallucinations. Or they may do nothing except get you in a lot of trouble.

The Sonoran Toad and the “God molecule”

The compound responsible for these effects is called 5-MeO-DMT. It’s also in plants as well as the Colorado River toad. And it’s so potent some people have dubbed it the “God molecule.”

The growing demand for powerful hallucinogenic substances now poses a risk to toad populations. These toads often die when humans relocate them outside of their home territory, and it’s common for diseases to spread when smuggler store them together.

All toads secrete toxins, which originally evolved to keep their bodies moist and later evolved as a method of self-defense. What sets the Sonoran Desert toad apart is its unique ability to convert bufotenine, a compound produced by many toads, into 5-MeO-DMT. When threatened, the toad excretes its potent mixture from glands behind each eye and on its legs as a defense mechanism.

The Sonoran Toad’s Toxic Friends

The Sonoran Desert toad isn’t the only species with psychedelic potential. The giant monkey frog from the Amazon Basin produces a toxic secretion called kambô. Its use as a psychedelic is debated. But some users report spiritual experiences similar to those induced by classic hallucinogens, Nevertheless, kambô does not activate the 5-HT2A receptor, a characteristic of traditional psychedelics. Indigenous populations have used kambô for centuries in shamanistic rituals to boost stamina.

Humans have a long history of seeking altered states of consciousness, often guided by the natural world. But our pursuit of these experiences should never come at the expense of the very creatures that offer us these extraordinary glimpses into other realms.

It’s important to balance our curiosity and respect for the natural world with conservation efforts to protect these species and their habitats from exploitation.

If you want to see and hear the toad in question, we found a reliable YouTube video. When it comes to this species, we urge you only to get information from reliable sources!

WTF Fun Fact 13474 – Once There Were No Mosquitos in Hawaii

by

Believe it or not, there were no mosquitoes in Hawaii until the 19th century.

In its early days, Hawaii was a natural utopia, a paradise that existed free of the annoying whine and itchy bites of mosquitoes. Native flora and fauna thrived without the interference of these bloodsuckers. This absence wasn’t by chance, though. Hawaii’s remoteness, surrounded by thousands of miles of open ocean, formed a natural barrier that kept mosquitoes, among other things, away.

The End of No Mosquitos in Hawaii

Everything changed in the early 19th century when mosquitoes finally found their way to the Hawaiian Islands. Brought inadvertently by humans, the first recorded arrival was in 1826 on a trading ship. The invasive species soon adapted to the tropical climate and began to breed in the islands’ plentiful standing water sources, spelling trouble for both the local ecosystem and the human population.

The Mosquito’s Impact on the Hawaiian Ecosystem

Once mosquitoes gained a foothold, the repercussions were significant. Hawaii’s native bird populations suffered drastically. Mosquitoes brought avian malaria and avian pox, diseases to which the indigenous birds had no immunity. This resulted in a significant decrease in bird populations, leading some species to the brink of extinction. The Hawaiian honeycreeper, for example, experienced a substantial decline, with some species entirely wiped out.

Humans also felt the effects of the mosquito invasion. Initially, the islands’ residents were not accustomed to the nuisance of mosquitoes. However, more than just a nuisance, mosquitoes brought diseases like dengue fever and the Zika virus, threatening public health. Moreover, tourism, a significant part of Hawaii’s economy, took a hit as the presence of these pests and the diseases they carried became a deterrent for some tourists.

Current Efforts to Control Mosquito Populations

Today, efforts are underway to control mosquito populations and mitigate their impacts on Hawaii’s ecosystem. Measures such as eliminating standing water, using mosquito repellents, and introducing mosquito predators like dragonflies are part of the strategy. In addition, genetic modification technologies are being explored to reduce the ability of mosquitoes to reproduce or carry diseases.

The late arrival of mosquitoes in Hawaii is a stark reminder of the profound effects human activities can have on isolated ecosystems. Even an event as seemingly minor as a mosquito stowing away on a ship can disrupt a delicate balance, causing ripple effects that last for centuries.

Gone are the days when there were no mosquitos in Hawaii. As the islands grapple with the ongoing challenges presented by mosquitoes, this tale provides valuable lessons about the importance of protecting the world’s unique environments from invasive species.

WTF Fun Fact 13473 – The Greyhound Saint of Lyon

by

Have you heard of Guinefort, the greyhound saint of Lyon, France?

The Legend of Guinefort, the Greyhound Saint

Guinefort’s story begins in the 13th century, nestled in the noble family of a knight who lived in a castle near Lyon. The knight had a faithful greyhound named Guinefort, who was entrusted with the protection of the knight’s infant son.

As the story goes, one day, the knight returned to his castle to find his baby’s cradle overturned, with Guinefort standing nearby, blood smeared on his muzzle. Assuming the worst, the knight believed Guinefort had harmed his child. In a fit of rage and grief, he slew the greyhound before discovering his infant son alive beneath the cradle, next to the lifeless body of a viper.

Guinefort, it turned out, had defended the child, killing the snake and saving the baby’s life.

The knight was filled with remorse and buried Guinefort in a well, planting trees around it as a memorial.

An Unconventional Saint

The story of Guinefort’s bravery and loyalty spread among the local people. They began to view the dog as a protector of infants, venerating him as a saint despite his canine status. A cult formed around Guinefort, with rituals involving mothers bringing their infants to his grave to seek his protection.

In the centuries that followed, Guinefort’s reputation as a protector of children persisted. Mothers continued to visit the grave, offering prayers and leaving tokens in the hope of invoking his protection.

The Church’s Stand on the Greyhound Saint

However, the veneration of a dog as a saint did not sit well with the Church. In the 13th century, Inquisitor Stephen of Bourbon discovered the cult and was horrified. He ordered the destruction of Guinefort’s shrine and condemned the practice, declaring it as heresy.

Despite these attempts, the cult of Saint Guinefort survived quietly among the local populace, passed down through generations. Even today, tales of the greyhound saint are still told in the region, keeping the legend alive.

The Greyhound Saint’s Cultural Impact

Guinefort’s story is not just a tale of a loyal dog. It has deeper cultural implications, reflecting the medieval society’s fears, beliefs, and social practices. The legend of Guinefort demonstrates the power of folklore and the human tendency to seek protectors and intercessors in a world filled with danger and uncertainty.

There are still references to Guinefort in literature, film, and even video games. His tale continues to captivate, providing a unique perspective on faith, folklore, and our relationship with animals.

While the original shrine no longer exists, one can still find traces of Guinefort’s veneration in Lyon’s folklore and oral traditions. Visitors curious about this peculiar piece of history can still explore the region, soaking up the rich history and cultural landscape that fostered the legend of a canine saint.

WTF Fun Fact 13463 – Dog Poop DNA Test

by

If you live near a dog owner who doesn’t clean up after their pup, you can now get a dog poop DNA test to track them down.

A company named PooPrints is one of a growing number of companies that will let you send in dog poop for detective work.

Poo Prints Dog Poop DNA Test

The concept is simple, yet genius. When dogs move into a participating apartment complex or housing community, they undergo a quick DNA cheek swab. The information is then stored in PooPrints’ vast database. If someone stumbles across an abandoned pile of dog poop, a small sample can be sent to PooPrints for DNA analysis.

With the precise accuracy of these tests, annoyed residents can ask their apartment complex to quickly ID and appropriately dealt with a rude dog owner, usually through a fine.

The man behind the mission, Tom Boyd, found inspiration in his own annoyance with irresponsible pet owners. He transformed his personal pet peeve into a thriving business with PooPrints now serving clients across the US, Canada, and the UK.

Unleashing Controversy

But this is more than just a business. PooPrints is making a significant environmental impact. According to the Environmental Protection Agency, pet waste is as toxic to the environment as chemical spills. It’s not just an eyesore; it’s a health hazard. By helping to enforce clean-up rules, PooPrints aids in reducing these environmental hazards.

However, as with any disruptive idea, PooPrints has also seen its share of controversy. For example, people have raised privacy concerns about collecting and storing pet DNA. Critics also point out that fines can disproportionately impact lower-income pet owners.

Despite the debate, PooPrints continues to grow. While the concept might seem absurd at first, it’s an innovative solution to an everyday problem. By holding pet owners accountable, PooPrints is turning unwelcome dog poop into a tool for cleaner, more harmonious communities.

WTF Fun Fact 13460 – Sharks in a Lake

by

There’s nothing quite like the ocean. But you can get some beach time in at the lake as well. It used to be a shark-free way to enjoy the water. But not anymore since there have been more than a few reports of sharks in a lake!

If you’ve swum in certain lakes around the globe, you might have shared a swim with these fascinating creatures.

Bull sharks are freshwater fans

While Great Whites may not make an appearance in our freshwater lakes, bull sharks, notorious for their ability to survive in both salt and fresh water, do make an appearance. This survival trick is all thanks to their advanced ability to osmoregulate their livers. This allows them to adapt to varying salinity levels, unlike their fellow hammerhead or tiger sharks.

One of the largest freshwater lakes in the Americas, Lake Nicaragua, sees these adaptable creatures as regular inhabitants. The bull sharks make their way through the San Juan River. They successfully navigate through eight rapids, much like salmon, to reach the lake and may reside in the lake for several years.

They exhibit some impressive rapids-navigation abilities not seen in other bull shark populations.

Unexpected sightings of sharks in a lake

Even a seemingly innocent round of golf can turn into a shark encounter at Queensland’s Carbrook Golf Club in Australia. In 1996, a massive flood seems to have left around six bull sharks trapped in the golf course’s freshwater lake. Since then, the shark population has been a consistent feature of the club.

The bull shark presence is not limited to Australia or the Americas. In Lake Pontchartrain, Louisiana, bull sharks have been spotted and even caught by anglers. A boy was reportedly attacked by a bull shark in 2014 in this lake. The sharks are known to venture more into the lake during the summer. But they retreat back to the Gulf of Mexico towards the year-end.

These fascinating creatures have also been observed in Lake Janoer in New Guinea. Oh, and you might see one in Lake Izabal in Guatemala, Lake Sentani in Indonesia, and Lake Bayano in Panama. (But note that despite a few shark sighting being reported in the Great Lakes, such as Lake Michigan, those have never been scientifically confirmed.)

In a more heartwarming encounter, Lake Maracaibo in Venezuela is home to a bull shark nursery. However, this particular lake may not be the best holiday destination. It holds the world record for the highest number of lightning strikes.

Freshwater lakes aren’t always shark-free

A river swim doesn’t eliminate the risk of encountering a shark. Three species of river sharks exist: the Ganges shark, the northern river shark, and the speartooth shark. These aquatic creatures can be found in the freshwater rivers in India and the brackish estuaries in northern Australia and New Guinea.

But don’t freak out (despite Summer 2023 being the year the ocean seems to be fighting back). It’s essential to remember that shark attacks, whether in the sea or a lake, are exceedingly rare. In fact, have a better chance of being bitten by a New Yorker than a shark!

WTF Fun Fact 13458 – Taxidermied Bird Drones

by

Researchers often look to nature for inspiration when designing machines and devices – now scientists from the New Mexico Institute of Mining and Technology are taking this concept a step further, building taxidermied bird drones.

Why use taxidermy bird drones?

The idea might seem disturbing or bizarre at first. A decade ago, a Dutch artist, Bart Jansen, had stirred conversation by turning a deceased, taxidermied cat into a furry quadcopter. However, the researchers from New Mexico Tech have a practical reason for their unique approach to creating ornithopters—drones that fly by flapping their wings like a bird.

Their aim is to harness the flight capabilities of birds whose lightweight bodies and flexible feathers give them remarkable maneuverability that outmatches the most sophisticated aircraft we’ve built.

According to a study presented at the American Institute of Aeronautics and Astronautics SciTech 2023 Forum, using actual bird parts can offer significant advantages over artificial materials engineered to mimic bird behavior.

The researchers believe that their bird-built drones can effectively camouflage in the air, being more likely to be ignored due to their realistic appearance. These drones may not excel in performing complex aerial maneuvers like a living bird, but they could become an essential tool in espionage or wildlife study.

From stealth to espionage

One unique advantage of using bird feathers in these taxidermied bird drones is the stealth capabilities they offer. Unlike the noticeable hum of an electric motor propelling a typical drone, a bird drone with flapping feathered wings could potentially sneak up on targets quietly without alarming them. This would be particularly useful in studying and observing wildlife in their natural habitats, without disturbing their normal behaviors. Military applications could also benefit from the stealth properties of these feathered drones, providing an innovative approach to surveillance and reconnaissance.

The current bird-built drones, however, have limitations. Unlike real birds that use their muscles to flex and shape their wings for executing intricate aerial maneuvers, these drones can only flap their stiff wings up and down to stay airborne. The challenge for the researchers lies in advancing the technology to imbue their bird drones with greater agility in flight.

The research from New Mexico Tech presents an intriguing intersection of biology and technology, pushing the boundaries of how we perceive and utilize drones. As they continue to refine their design, these bird-built drones could revolutionize areas from espionage to wildlife observation. Yet, ethical considerations, including the use of taxidermied birds, will undoubtedly be part of the ongoing discourse as this technology evolves.

WTF Fun Fact 13457 – Crocodile’s Virgin Birth

by

In a scientific breakthrough, researchers have recorded the first known instance of a crocodile’s virgin birth. The female American crocodile lived in isolation for 16 years at a zoo in Costa Rica.

What’s the story behind the crocodile’s virgin birth?

This incredible discovery has revealed a surprising reproductive capability in crocodiles and could provide insight into their prehistoric relatives.

In 2018, the female American crocodile, despite her solitary existence, laid 14 eggs in her enclosure, which is not an uncommon occurrence among captive reptiles. However, things took an unexpected turn when, after three months of incubation, scientists discovered a fully formed, stillborn baby crocodile in one of the eggs.

Genetic analysis of the fetus revealed that this was a result of facultative parthenogenesis (FP), a type of reproduction that occurs without the genetic contribution of males. Essentially, the mother’s egg cell developed into a baby without being fertilized by a male’s sperm cell.

Facultative parthenogenesis explained

In FP, the process of egg cell formation divides a precursor cell into four cells. One of these becomes the egg cell, retaining key cellular structures and the gel-like cytoplasm, while the others contain extra genetic material. Interestingly, one of these cells acts like a sperm cell, fusing with the egg to facilitate fertilization.

While this type of reproduction, colloquially known as a “virgin birth,” has been documented in various species of fish, birds, lizards, and snakes, this is the first-known instance in a crocodile.

The American crocodile is a vulnerable species at risk of extinction. According to one hypothesis, FP may be more prevalent among species on the brink of extinction. The discovery of this unusual reproductive strategy could have significant implications for the conservation of endangered crocodile populations.

A glimpse into the prehistoric past

This astounding discovery in Costa Rica could also open new windows into the ancient past. As the study suggests, the “virgin birth” phenomenon might offer insights into the possible reproductive capabilities of extinct archosaurian relatives of crocodilians and birds, specifically members of Pterosauria and Dinosauria that roamed the earth during the Triassic Period about 250 million years ago.

WTF Fun Fact 13455 – Bird Nest Spikes

by

Bird nest spikes sound pretty uncomfortable. But the birds have defeated us since they’re now using anti-bird spikes designed to keep them away as materials to build their nests! Nature always finds a way.

How are birds defeating the spikes?

It’s magpies specifically that are making headlines. They’re the birds that have been found using the anti-bird spikes designed to deter them as construction material for their nests. This fascinating behavior underscores these birds’ remarkable intelligence and adaptability.

Anti-bird spikes are rows of pointed metal or plastic prongs designed to deter birds from perching on buildings, bridges, or statues. People use them when they don’t want birds building nests or leaving droppings in a specific area. And since birds can spread disease, some people see them as dirty.

However, far from being deterred, magpies have decided to turn the tables on humans by using these spikes to their advantage.

Bird nest spikes for a spiteful home

We kid. The birds aren’t spiteful. They’re just trying to survive.

Birdwatchers have observed magpies collecting these anti-bird spikes and weaving them among twigs and branches to create sturdy and secure homes. The supposed deterrents have become a beneficial resource for these intelligent creatures.

Scientists believe that these birds’ unexpected behavior is an example of neophilia, an attraction to new things. Unlike neophobia, a fear of new things common in many animals, neophilia is characteristic of certain bird species, particularly those known for their intelligence like magpies and crows. The anti-bird spikes are new elements in their environment, so the birds investigate them and then find a way to use them to their advantage.

Implications for bird deterrence

The use of anti-bird spikes by magpies challenges the effectiveness of this deterrence method. If the birds can repurpose these structures for their use, their presence may not achieve the intended effect of keeping the birds away. This revelation could prompt a re-evaluation of current bird deterrent strategies.

The behavior of these magpies and crows using anti-bird spikes underscores the impressive cognitive abilities of these birds. It’s yet another example of their capability to adapt to and exploit the human-altered environment, offering further proof that these birds possess a high level of intelligence and problem-solving skills.

The birds’ actions also serve as a reminder of the continuous interplay between wildlife and human spaces. As humans encroach more on natural habitats, animals must adjust and adapt to survive. These magpies and crows turning a human deterrent into a beneficial resource is a clear instance of this adaptive behavior.

Conclusion

In their creative use of anti-bird spikes, magpies and crows have provided a fascinating case study of avian ingenuity. They’ve turned a human-made deterrent into an advantageous resource, demonstrating their intelligence and adaptability. These observations could have significant implications for how we design bird deterrents in the future. It also invites us to appreciate and respect the remarkable cognitive capabilities of these feathered urban dwellers.

WTF Fun Fact 13453 – Shark GPS Tracker Draws Shark

by

A great white shark with a GPS tracker drew a shark in the waters off the eastern coast of North America. Was he “punking” researchers? Telling us he knows what we’re up to? Do sharks mysteriously swim in shark-shaped patterns? Or are we just seeing what we want to see?

Don’t answer that – it’s not as funny if you do.

The unconventional artist

Art and creativity are typically deemed human endeavors. But perhaps they also belong to the great white shark who unwittingly sketched a self-portrait, using tracking data as its brush.

Our artist is a mature male great white shark, named Breton by the OCEARCH team. He’s a frequent wanderer off the Atlantic Ocean coast of Long Island, New York. As part of the shark tracking initiative, he carries a tracker affixed to his dorsal fin. This tracker collects and relays data whenever the shark surfaces, providing an almost real-time map of the shark’s movement.

Did the shark GPS tracker draw a shark?

A May 2022 observation of Breton’s tracking data offered an unexpected delight to the researchers. It seemed as though Breton had swum in a pattern that mirrored the outline of a great white shark when seen from above.

OCEARCH shared the data on its social media, and the internet quickly took notice.

The tracking path captured not only the body’s curve but also the classic angular shape of the tail and the pectoral fins. It sure looks like a shark!

Coincidence or Design?

As fascinating as Breton’s journey may seem, it is essential to underline that the ‘self-portrait’ was purely coincidental. Sharks navigate based on instincts and sensory information, not a predetermined design. Sorry if you needed to be told that – but people have been studying sharks for a long time. That doesn’t mean we can’t enjoy the coincidence!

While the artistic byproduct is captivating, the primary purpose of tracking sharks like Breton is conservation. By learning about migration patterns, feeding areas, and breeding grounds, scientists can devise effective strategies to safeguard these creatures. The knowledge gained from such tracking can inform the establishment of marine protected areas and fishing regulations.

The good news is that Breton’s self-portrait can serve as a symbol for raising awareness about the threats facing great white sharks.

Issues like overfishing, habitat degradation, and climate change pose significant threats to these magnificent creatures. Breton’s story is an opportunity to engage the public and rally support for shark conservation.

WTF Fun Fact 13443 – Dead Fruit Flies

by

When fruit flies see or smell their dead comrades, their own lives are cut short. Talk about putting a damper on your day!

Fruit flies stress after seeing other dead fruit flies

If you’re a fruit fly, seeing one of your fallen is not just unsettling. It’s downright harmful to your health. Despite their diminutive size, experience stress and negative health effects when they witness the remains of their kin.

Neuroscientists have found that when fruit flies (Drosophila melanogaster) see their deceased fellow flies, specific brain cells are triggered.

And these aren’t just any brain cells. They are neurons that respond to visual stimuli, known as visual projection neurons (VPNs). These cells relay information from the flies’ eyes to their brains, helping them interpret and react to what they see.

What’s going on in a fruit fly’s brain?

But let’s add a pinch of intrigue to the mix. These neuroscientists didn’t stop at merely identifying the type of neurons involved. They zeroed in on the specific group of neurons that reacts to the sight of dead flies. The neurons in question are part of a cluster known as the “globus pallidus.” This is an area associated with movement and learning.

These scientists have discovered the precise neighborhood in the fruit fly’s brain where the “dead fly sighting stress response” takes place.

So, what happens when these neurons fire? In short, they trigger a series of stress responses that have a tangible impact on the fruit flies’ health and lifespan. As the sight of a dead fellow fly becomes ingrained in the fly’s brain, it alters the expression of stress-related genes, tipping the physiological balance and leading to a shorter lifespan.

This discovery has raised intriguing questions about the evolution of empathy and social responses in insects. While fruit flies may not experience empathy in the way humans do, their stress response to seeing dead comrades suggests a level of social awareness. This raises the question: why would such a response evolve? One possibility is that the sight of death serves as a warning signal, indicating the presence of potential threats or diseases, thus prompting the fly to modify its behavior.

However, this remarkable finding does more than just throw light on fruit flies’ stress responses. It could also contribute to our understanding of how human brains process stress and trauma. Humans, like fruit flies, have neurons that respond to visual stimuli. Therefore, these findings could lead to a better understanding of how our brains respond to stressful visual experiences, and potentially inform treatments for stress-related disorders.

WTF Fun Fact 13438 – Killer Whales are Dolphins

by

Here’s a bit of trivia that might just turn your marine world upside down: killer whales, also known as orcas, aren’t whales. They’re actually the largest dolphins in the sea! That’s right, Shamu, the poster child for what we envision when we think of whales, is really more Flipper than Moby Dick.

Are orcas whales or dolphins?

Orcas, known for their black bodies, striking white patches, and formidable size, are a sight to behold. However, despite their common name – killer “whale” – these majestic creatures are more closely related to their smaller, playful dolphin cousins.

Now, this might seem like a marine biologist trying to mess with you, but it’s all in the scientific classification. Orcas are part of the oceanic dolphin family, known as Delphinidae, which includes other well-known species like the bottlenose dolphin and the common dolphin. Essentially, all killer whales are dolphins, but not all dolphins are killer whales.

In fact, the orca’s scientific name, Orcinus orca, loosely translates to ‘demon from hell’, a nod to their reputation as fierce hunters. But don’t let the ominous name scare you, these creatures are incredibly intelligent and social.

Orcas, like their dolphin relatives, are known for their intelligence and complex social structures. They live in tight-knit groups known as pods, led by a matriarch, often the oldest female. Within these pods, they communicate using a series of clicks, whistles, and body movements.

What’s fascinating about orcas is that different pods can have different cultures, dialects, hunting techniques, and even dietary preferences. This level of cultural diversity is virtually unheard of outside of human societies, further cementing their place in the pantheon of intelligent life on Earth.

Classifying creatures

However, their classification as dolphins doesn’t make them any less ‘killer’. They are apex predators, the top of the food chain, preying on seals, fish, squid, and even other whales. Their name, ‘killer whale’, is actually a bit of a misnomer. It originates from the term ‘whale killer’, coined by sailors who observed these dolphins attacking larger whales.

Despite being top predators, orcas face a host of challenges in the modern world, ranging from pollution and loss of prey to climate change and captivity. Our understanding of orcas, their behaviors, and their needs, is crucial for their protection.

Perhaps one of the best ways we can appreciate orcas is to realize that they’re not so different from us. They’re intelligent, they’re social, they’re diverse, and they’re vulnerable. They’re dolphins that have adapted to their environment in remarkable ways, rising to the top of the oceanic food chain.

So next time you hear the term “killer whale”, remember, these magnificent creatures are actually the ocean’s largest dolphins. Just another example of how the natural world continues to surprise and inspire us!
