WTF Fun Fact 13478 – Dolphins May Use Parentese Voice

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

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

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

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

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

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

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

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

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.
