WTF Fun Fact 13549 – Australia is Wider than the Moon

It’s hard to get a handle on just how big some land masses are – but while we know the land down under was big, we were still surprised to find out that Australia is wider than the moon! Of course, they’re not the same shape, so that makes a difference in terms of their size.

Australia is Wider than the Moon – With a Caveat

When discussing Australia’s vastness, people often mention its sweeping deserts, extensive coastline, and large metropolises. But a fact that frequently catches many off guard is that, in terms of width, Australia is wider than the moon.

The moon’s diameter measures about 3,474 kilometers. It might seem massive when you gaze up on a clear night, especially considering it’s over 384,400 kilometers away from Earth. But in terms of sheer size, it’s modest compared to some of the celestial bodies in our vast universe.

Australia’s Impressive Span

Stretching from its westernmost point of Steep Point in Western Australia to its easternmost tip at Cape Byron in New South Wales, Australia boasts a width of approximately 4,000 kilometers (2,485 miles). This makes Australia over 500 kilometers wider than the moon. It’s an astonishing fact, given that the moon appears so dominant in our night sky.

Drawing from NASA’s data, the moon’s equatorial diameter measures at 3,476 km (2,159 miles). But this comparison demands further nuance.

The moon’s form is spherical, making it a three-dimensional entity. Australia, while vast, exists more like a two-dimensional plane on the surface of the Earth. This distinction is crucial. While Australia’s width might surpass that of the moon, the moon’s total surface area, encompassing 37.94 million square kilometers (14.65 million square miles), vastly exceeds Australia’s land area.

Perception vs. Reality

One might wonder, if Australia is wider than the moon, why does the moon appear so large in our sky? The answer lies in perception. The moon orbits Earth at a relatively close distance, making it appear larger to us. Additionally, phenomena like the “moon illusion,” where the moon appears larger near the horizon than when higher in the sky, can further skew our perceptions.

On the other hand, it’s challenging for our minds to grasp the true expanse of Australia. Most people experience countries piece by piece, city by city, or via maps that sometimes distort scale due to their projection. Thus, the full breadth of Australia’s landscape is not always immediately evident.

WTF Fun Fact 13548 – All Clownfish Are Born Male

All clownfish are born male. But they can change their sex.

The Basics of Clownfish Biology

Clownfish are reef-dwelling fish, easily recognizable by their striking orange color punctuated with white bands. They live among sea anemones, forming a symbiotic relationship that provides protection for the fish and food for the anemone. But their physical appearance and habitat preferences aren’t the only intriguing aspects of clownfish. Their reproductive system is a study in adaptability and role reversal.

In the animal kingdom, there are creatures that can change their sex under specific conditions. Clownfish are protandrous hermaphrodites, meaning they are born male and have the potential to turn female later in life. In any given clownfish group or “school,” there’s a strict hierarchy. At the top sits the dominant female, the largest of the group. Below her is the dominant male, the second-largest. The rest of the group consists of smaller, non-reproductive males.

Clownfish Are Born Male But Not All Stay Male

When the dominant female dies or is removed from the group, an astonishing transformation occurs. The dominant male undergoes a sex change, turning into a female to fill the vacant role. Following this, the next in line from the non-reproductive males will grow larger, becoming the new dominant male. This ensures that the group remains reproductive.

This dynamic transformation isn’t just about filling a role. It’s a strategic evolutionary adaptation. In the ocean, where challenges abound, ensuring a breeding pair is always available maximizes the chances of offspring survival. The hierarchy and subsequent role shifts allow clownfish groups to maintain a breeding pair without needing to seek mates from outside their established territory.

The Science Behind Why All Clownfish Are Born Male

The process by which clownfish change their gender is a complex one, driven by hormones and external environmental factors. When the dominant female is no longer present, the absence of her hormones, which inhibited the sex change in the dominant male, triggers a shift. The dominant male’s testes transform into ovaries, and he becomes a she. This process can take a few days to weeks. Once the transformation is complete, the newly formed female can reproduce with the new dominant male.

Implications for Conservation and Aquariums

Understanding the clownfish’s unique reproductive strategy is crucial for conservation and those who keep them in aquariums. Overharvesting clownfish for home aquariums can disrupt their complex social structures, making it essential for collectors and hobbyists to be aware of their needs.

When kept in aquariums, clownfish can still display their natural gender transition behaviors. If a female clownfish in a home tank dies, it’s not unusual for the largest male to transition to take her place, provided the environment mimics their natural habitat closely.

A Window into Evolutionary Adaptations

The clownfish’s ability to change its gender as needed is a testament to the wonders of evolution. This adaptability provides them with a distinct advantage in ensuring their survival. It also serves as a reminder of the myriad ways nature devises solutions to challenges.

Clownfish are not the only creatures with such capabilities. Other fish species, and even some reptiles, have the ability to change their sex based on environmental or social triggers. However, the clownfish remains one of the most iconic examples, and their captivating life story adds another layer of intrigue to these already beloved marine creatures.

WTF Fun Fact 13547 – Dolphin Bromance

Dolphin bromance paints a vivid picture of the profound relationships male dolphins cultivate. Dive into the oceanic world, and you’ll find a complex tapestry of social interactions, with dolphin bromance standing out as one of the most captivating threads.

The Nature of Dolphin Bromance

Dolphins, with their playful antics and impressive intelligence, have always intrigued scientists. Within their pods, one can observe a complex hierarchy and a myriad of relationships. Particularly interesting are the coalitions formed by male dolphins. Often, groups of two or three males will bond, creating an alliance that lasts for many years. These bonds aren’t merely casual acquaintances formed out of convenience. They’re strategic, aiding these marine mammals in everything from securing mates to defending territory.

Strategies and Benefits

The primary objective of these bromances is two-fold. First, these alliances help in securing mating rights with females. In the vast expanse of the ocean, having allies ensures that a male dolphin has better chances during the mating season. Secondly, in an environment filled with potential threats, having a dependable coalition means better defense mechanisms against predators or rival male groups.

In addition to these practical benefits, these alliances also seem to offer emotional support. Dolphins are known for their advanced cognitive abilities, and these bonds hint at an emotional depth that’s still being explored. Observations have shown members of these alliances engaging in synchronized swimming, mutual grooming, and other cooperative behaviors.

The Emotional Depth

Understanding dolphin bromance isn’t just about recognizing the strategic benefits. There’s an emotional aspect to these relationships. Dolphins, known for their high levels of intelligence, showcase behaviors hinting at deep emotional connections. Members of these male alliances are often seen supporting each other during times of distress, echoing the kind of empathy and understanding seen in close human relationships.

It’s not uncommon to see paired dolphins assisting an injured member, or even just spending time in close proximity, echoing the behaviors seen in close human friendships. The depth of these bonds and the extent of their emotional intelligence are still subjects of research, but there’s no denying the profound connections they showcase.

Implications for Marine Biology

The study of these bromances doesn’t just shed light on dolphin behavior; it offers insights into the broader realm of marine biology. Understanding the nature of dolphin relationships helps in conserving their habitats and ensuring their survival. Additionally, it prompts a deeper dive into the emotional lives of other marine creatures.

WTF Fun Fact 13544 – How Long Can a Tarantula Live Without Food?

If you’re a tarantula owner, hopefully you’re not asking yourself, “How long can a tarantula live without food?”

However, if for some reason you need to know, the answer may astound you.

So, How Long Can a Tarantula Live Without Food?

Tarantulas, the large, hairy spiders that evoke fear in many, hold an astonishing survival capability – the ability to endure up to two years without a meal.

It’s a feat that many creatures on Earth would find hard to match.

But how does this eight-legged creature achieve such a prolonged fast?

Unique Physiology Allows Tarantulas to Live Without Food

Unlike mammals that require regular food intake for energy and maintenance, tarantulas have a slower metabolism. This low metabolic rate means that they don’t burn energy at the same speed as other animals. Consequently, they can conserve energy over long periods, allowing them to survive during times of food scarcity.

While they can survive without food for a long duration, access to water remains crucial.

Tarantulas, like all living organisms, need water for basic cellular functions. They can go weeks without it, but eventually, the lack of water will become a bigger concern than the lack of food.

When in their natural habitat, tarantulas will often burrow deep into the ground to access cooler and more humid conditions, which helps them maintain their water balance.

Refusing Food

Tarantulas, throughout their lifetime, go through periods of molting. This is when they shed their exoskeleton to allow for growth or to repair any damage.

During the pre-molt and molting phases, tarantulas tend to refuse food altogether, further lengthening the periods between meals. Additionally, the younger the spider, the more frequent these molting cycles are.

As tarantulas mature and their growth slows, their molting becomes less frequent, and the intervals between feeding can extend even further.

Food Scarcity Determines How Long A Tarantula May Go Without Food

In their natural habitats, tarantulas may not always find prey readily available.

Drought, seasonal changes, or other environmental factors can result in food shortages. Thus, this incredible adaptation to long fasting durations is not just an interesting fact; it’s a survival mechanism. It ensures that during lean times, the tarantula can wait it out, remaining relatively inactive, conserving energy, and then springing to action when food becomes available again.

Another factor that plays into the tarantula’s ability to go without food for extended periods is its size.

Larger tarantulas have more fat reserves than their smaller counterparts. These reserves provide the necessary energy during food shortages. Consequently, bigger tarantulas can often go longer without eating compared to younger, smaller ones.

Don’t Let Captive Tarantulas Go Without Food

While tarantulas have this remarkable ability, those who keep them as pets should exercise caution. In captivity, it’s not uncommon for tarantulas to refuse food for various reasons. Whether it’s due to stress, an impending molt, or changes in their environment, pet owners should monitor their spiders closely.

If a tarantula doesn’t eat, it’s essential to ensure that it has access to fresh water. And while they can go without food, this doesn’t mean they should be deliberately starved. Their natural ability to fast is a survival mechanism in the wild, not an invitation for neglect.

WTF Fun Fact 13535 – Vampire Bats French Kiss

Did you know that vampire bats French kiss? Don’t worry – it gets weirder from there. They kiss with mouthfuls of blood.

Bats “kissing” with mouthfuls of blood may seem strange. Yet, it tells a story of survival and deep bonds. It’s nature’s way of ensuring that in a world full of challenges, no bat is left behind. Through their blood-sharing rituals, vampire bats teach us about trust, cooperation, and the essence of life. Who knew?

The Vampire Bat

Bats rule the night skies and stand out as the only flying mammals. Their unique abilities, like echolocation, have always intrigued scientists. But among their many attributes, one behavior stands out as both peculiar and endearing. It’s their method of sharing food. In the case of the vampire bat, it means regurgitating blood.

Of the 1,300 bat species worldwide, only three have a taste for blood. These vampire bats hail from the Americas. Unlike the myths that surround them, these creatures have evolved to consume the blood of either birds or mammals, not humans.

For a vampire bat, finding a meal involves skill. They hunt using a combination of heat sensors and a keen sense of smell.

Once they locate their prey, they make a precise cut to access the blood, ensuring minimal harm to the host. Their saliva contains unique enzymes that prevent the blood from clotting, allowing them to feed efficiently.

Vampire Bats French Kiss for Solidarity

Vampire bats exist in a system of reciprocity. They thrive in closely bonded colonies where sharing is not just caring; it’s a matter of life and death.

A bat that goes two days without a blood meal is at risk of starvation. However, in these communities, a bat that has fed for the night will often regurgitate and share its meal with a less fortunate mate.

This isn’t random charity. Bats remember past favors and are more likely to share with bats that have previously shared with them. Among mates, this sharing ritual cements their bond, a sign of trust and affection.

The Role of Hormones

Oxytocin, commonly known as the “love hormone,” plays a part in this sharing ritual. In many mammals, oxytocin fosters a bond between mothers and their young. In vampire bats, elevated oxytocin levels coincide with their blood-sharing behavior. It strengthens the sense of trust and community among bats in a colony.

The act of vampire bats “kissing” with blood might unsettle some. But there’s a profound message embedded in this behavior. In the harsh realities of nature, where survival is a daily challenge, vampire bats prioritize community. They understand the significance of trust and cooperation. Through their unique rituals, they highlight the importance of unity, reminding us that in the face of adversity, no one should be left behind.

It’s easy to misunderstand or fear vampire bats. They’re often painted as malevolent creatures in legends and folklore. The reality is quite different. While they do consume blood, vampire bats are integral to their ecosystems. They’re not villains but rather creatures of survival, teamwork, and kinship.

WTF Fun Fact 13532 – Neanderthal Flower Burial Evidence

A possible explanation for a Neanderthal flower burial is intriguing scientists.

Since the 1950s, archaeologists have shown interest in the Shanidar Cave in northern Iraq. That’s because it holds the remains of nine Neanderthals and features a “flower burial” site.

The flower burial was due to a large amount of pollen around one of the skeletons. This led to speculations about whether the pollen was part of a human burial ritual. If so, this would indicate that Neanderthals were far more complex than we previously imagined.

But recent research has introduced a new player into this ancient whodunit: bees.

What is the Neanderthal Flower Burial?

The initial interpretation of the pollen suggested a ceremonial “flower burial,” positing that the Neanderthal in question was of considerable importance, perhaps a shaman.

If true, this finding would assign attributes like empathy and ritualistic behavior to Neanderthals, traits previously thought exclusive to Middle Palaeolithic Homo sapiens.

However, some people contest the theory, arguing that other animals could have deposited the pollen by dragging flowers to their burrows, or that the pollen presence could be a mere coincidence.

Studying Pollen for Answers

Palynology, the scientific study of pollen, spores, and microscopic plankton, has provided new insights. Researchers studying the evidence from Shanidar Cave noticed that the mix of pollen species was unlikely to be in bloom at the same time.

This casts doubt on the “flower burial” theory, implying that the pollen didn’t all deposit at once.

Moreover, the mixed nature of the pollen suggests a different deposit vector, rather than placement of whole flowers in the grave.

This led to a unique hypothesis: could bees be the agents of this intriguing pollen placement?

Were Bees Responsible for the So-Called Neanderthal Flower Burial?

The idea is not as far-fetched as it sounds. Bees, especially solitary bees, gather pollen from multiple flower species. They create burrows lined with a mix of pollen for their larvae to feed upon. We’ve discovered such burrows in Shanidar Cave. Interestingly, the ancient pollen around the grave appears corroded and flattened, indicating great age and coinciding with the Neanderthals’ era.

Researchers incline toward the belief that nesting bees deposited the pollen, given their capability to forage multiple flower species simultaneously. The presence of bee burrows in the less-trafficked areas of the cave near the rear wall supports this theory. Moreover, ancient silty clay-lined insect burrows excavated from the cave further corroborate the idea that bees were active in that region during the Neanderthals’ time.

Were Other Animals Involved?

Identified immature pollen grains could have come through a different mechanism—perhaps humans, other animals, or even the wind carried them in.

It’s interesting to note that researchers have observed giving “floral funerals” to bees. However, these acts likely store food or waste rather than serve as ceremonies. This recursive loop in nature, where animals engage in practices mirroring human cultural behaviors, adds another layer to the study.

The recent study’s authors conclude that nesting bees probably deposited the mixed pollen, making the “Flower Burial” hypothesis seem unlikely.

This new perspective redirects the debate to a broader and arguably more significant question. Namely, “What does this cluster say about their sense of space, place, and perhaps, community?”

The bee hypothesis may not completely settle the mystery surrounding the Neanderthal “flower burial.” But it does open up new avenues for understanding the behaviors and interrelationships among ancient species—both human and insect—that shared the environment thousands of years ago.

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 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 13511 – The Icelandic Alfhol


In the enchanting landscapes of Iceland, you might stumble upon a tiny, intricately designed house called an Alfhol.

Alfhóls are built specially for the huldufólk, or hidden folk, of Icelandic folklore. Many Icelanders still hold a genuine belief in these elves and construct these homes as a gesture of goodwill, ensuring harmony between the human and the mystical realms.

The Icelandic Alfhol and it’s Inhabitants

One of the most captivating aspects of Icelandic culture is the belief in the hidden folk, or the huldufólk. These are not just tales for children; many Icelanders hold a genuine belief in these invisible entities, often associated with elves.

Some Icelanders believe that these beings, often invisible to human eyes, lead lives parallel to ours, having families, tending to livestock, and even attending church. And just as humans need shelter, so too do these hidden folk.

An Alfhol is a miniature house, often intricately designed to resemble traditional Icelandic homes. Constructing an Alfhól is a gesture of goodwill. Disturbing rocks and hills, believed to be the residences of these beings, is thought to bring misfortune. By building them a dedicated house, Icelanders hope to maintain harmony with their unseen neighbors.

While some Alfhóls are simple stone structures, others can be quite elaborate, replicating churches, homes with turf roofs, or even modern-day constructions. Attention to detail is evident in many of these tiny abodes, complete with doors, windows, and external decorations.

The Alfhol in Icelandic Culture

The belief in huldufólk is deeply entrenched in Icelandic culture. This is not a relic of the past; these traditions are very much alive today.

There have been instances where road construction projects in Iceland were altered or postponed due to concerns about disturbing the habitats of the hidden folk. In some cases, locals have even sought the help of mediums to communicate with the elves and seek their approval before proceeding with construction.

Iceland has festivals where the huldufólk are central figures. During these events, Alfhóls might receive gifts or offerings, symbolizing the harmonious relationship between humans and the hidden folk.

Why the Deep-rooted Belief?

One might wonder why, in a country as modern as Iceland, such a belief persists. There’s no singular answer, but a combination of factors contribute:

The rugged landscapes of Iceland have shaped its inhabitants. Respect for nature, and the mysteries it holds, is a cornerstone of Icelandic culture. The belief in huldufólk is an extension of this respect.

Stories of elves and hidden folk have been passed down through generations. These tales are a part of Iceland’s rich oral tradition, giving them a life of their own.

Whether one believes in the huldufólk or not, the Alfhóls stand as symbols of Iceland’s cultural identity. They represent a bridge between the ancient and the modern, the seen and the unseen.
