WTF Fun Fact 12757 – The Bahamas’ Underwater Statue

by

Have you ever wanted to see a famous statue but didn’t want to wait in line?

Well, how do you feel about going to the Bahamas to see it?

Ok, NOW, how do you feel about diving into the crystal clear ocean about 16 feet down to see it?

If you’re still thinking “this sounds great!” it might be time to book a trip to Nassau, Bahamas.

What, exactly, is the underwater statue “Ocean Atlas”?

According to Culture Trip (cited below): “You’ll find Ocean Atlas, a spectacular underwater sculpture byJason deCaires Taylor,off the western coastline of New Providence, which has the largest population of any island in the Bahamas. It’s also where you’ll find the Bahamian capital, Nassau. Ocean Atlas is the world’s largest single underwater sculpture, and it doubles as a navigational aid, with a flag attached to the top poking above the water.”

The sculpture isn’t of the Greek god himself, but of a little girl carrying the weight of the ocean on her shoulders.

No mercy from Zeus

If you remember being taught about ancient Greek gods and goddesses, Atlas was a Titan – one of the deities who came before the ancient Greek gods. When the Titans tried to fight the gods, Atlas’ punishment from Zeus (who was, let’s face it, a real jerk) was being forced to hold up the heavens for eternity.

The statue is just a nod to the myth, and the subject is a local Bahamian girl. She can be viewed from just 16 feet beneath the clear water, so snorkeling or scuba diving will give you a great view of the piece which weighs 66 tons.

A sustainable underwater sculpture

The coolest thing about the “Ocean Atlas” is that it’s made from pH-neutral materials and does not damage the surrounding ocean environment (other than draw tourists). it was actually designed to draw divers away from more popular spots so the reefs and aquatic life could start to recover.

According to the artist’s website, the materials are stainless steel, pH-neutral cement, basalt and aggregates.

It’s just not an option to close some of those other sites since many tourists go to the Bahamas just to dive and see the reefs.

A whole new world

The VERY coolest thing about “Ocean Atlas” is that it is now breeding its own ecosystem as wildlife is attracted to it and it serves as an artificial reef that houses some coral (which is what gives reefs their color).

It’s also not super easy to get to, so you have to rent a charter boat and follow directions pretty closely in order to see her. In other words, humans have to behave responsibly around the statue so it’ll be there for the oceans and the people who live above them to enjoy. –WTF fun facts

WTF Fun Fact 12756 – Roadless Giethoorn Village

by

If you’re headed to The Netherlands to visit the Dutch village of Giethoorn, don’t bother renting a car. There’s nowhere to drive it.

Most of Giethoorn is traversed by boat along its canals. Of course, if you need some more exercise, there are paths for pedestrians and bicycles.

Visiting a fairytale in Giethoorn Village

Many call it a “fairytale” village, in part because of the thatched-roof houses and beautiful views. But it’s also incredibly quiet without any automobiles adding to the noise pollution.

The village is a collection of small “peat islands,” and those islands are connected by bridges (but they’re still not roadways). It is believed to have been founded in the 12th century and named in the 13th century.

According to National Geographic (cited below): “The story goes that its original farmer-settlers discovered a collection of horns belonging to wild goats thought to have died in the Flood of 1170. “Goat horn,” or “Geytenhoren,” was shortened to Giethoorn, and the name stuck. Centuries post-flood, water continues to define the village’s living history and landscape.”

When you boat, hike, or otherwise traverse the landscape, all you can hear is nature.

Getting to Giethoorn Village

NatGeo also tells you how to plan a trip: “You can get to Giethoorn by a combination of train and bus. To avoid crowds, opt for the months of April, May, June, or September, and keep in mind that weekday visits may be best. Though this “Dutch Venice” feels quite removed from capital city of Amsterdam, it’s only about 75 miles away. And a two-hour journey is well worth the feeling of traveling back in time.”

I don’t know about you, but I could certainly use some peace and quiet and a few days away from honking horns, revving motorcycles, and all the city sounds that make it hard to hear the natural world. – WTF fun facts

WTF Fun Fact 12755 – The Caño Cristales, Colombia

by

The Caño Cristales is a river in Colombia that some call the “Liquid Rainbow.”

But before you start planning a trip to the Colombian National Park of La Macarena, you should know that it’s rare to see all of these colors together. For the most part, the river looks red.

What causes the colors of the Caño Cristales?

The water of the river is actually crystal clear. It’s what lies beneath that brings the river to life – quite literally.

The Caño Cristales lies at the center of three distinct ecosystems, so it’s hard for flora or fauna to thrive there. But one organism has managed to get the hang of it –

is quite clear due to a lack of biodiversity. The colors are caused by red algae called Macarenia clavigera that cling to the rocks beneath and reflect different hues depending on the depth of the water and time of year.

Care for a visit to Caño Cristales?

If you do want to visit the Caño Cristales, it’s most colorful during the algal bloom and will turn red from late May and late November, but the peak time to see the colors is between July and October.

But you cannot visit alone – it’s just too hard to get to. You’ll need a guide for the park. You also cannot swim or be anywhere near the river if you’re wearing sunscreen or any body cream, since it may kill the algae.

But according to Culture Trip, “In spite of that, there is a lot more to see and do on a tour to Caño Cristales than just seeing the red river. The river itself is located alongside the huge La Macarena National Park, which is a vast area home to savannahs, incredible rock formations, jungles, and bird and mammal watching. Most tours last three to four days and take in a variety of sights.” – WTF fun facts

WTF Fun Fact 12754 – Sudan Pyramids Outnumber Egypt’s

by

Interested in ancient civilizations? Want to see pyramids without all the tourists? Then you may want to consider visiting the Meroe region in Sudan. In Sudan, pyramids outnumber the Egyptian kind by nearly 2:1.

Nubian pyramids in Sudan

The pyramids belong to the ancient Nubian kings, who lived in the northern part of present-day Sudan. Meroe was the capital city of the Kingdom of Kush. The structures themselves are nearly 5000 years old and are largely untouched these days.

The main source of destruction to the pyramids was an Italian “explorer” named Giuseppe Ferlini. He blew up quite a few and destroyed the tops of many structures in his hunt for the kings’ treasures in the 1880s.

What’s inside Sudan’s pyramids

These little-known Nubian tombs have paintings on the inside celebrating the kings buried inside. And since the Nubians did business with other ancient civilizations, you can see Greek and Roman, influences in the artwork.

Since the Kushite kingdom is part of the Nile River Valley, the most prominent influence is that of the Egyptians. (Of course, Egypt’s pyramids are much older, dating back to the era of the New Kingdom from the 16th century BC to the 11th century BC).

Of course, many of the tombs were raided by Ferlini during his destructive episode, and the “loot” now resides in many European museums. But they had been plundered in ancient times as well.

Preserving the past

Luckily, the Nubian pyramids are now a UNESCO World Heritage Site and are generally protected from more harm. Until 2019, National Geographic funded further excavations of the site to learn more about the ancient kings and their civilization.

Much of the excavations require researchers to dive underwater to enter the structures.

According to NatGeo, “The largest and oldest pyramid at Nuri belongs to its most famous resident: the pharaoh Taharqa, a Kushite king who in the seventh century B.C. rallied his troops to the northern edges of his empire to defend Jerusalem from the Assyrians, earning him a mention in the Old Testament.” – WTF fun facts

WTF Fun Fact 12752 – The Loudest Animal

by

What would be your guess for the loudest animal on earth? A lion? An elephant? What about a shrimp?

Ok, but what about a specific type of pistol shrimp named after the bank Pink Floyd? That sounds a bit more believable,

The loudest animal

You’ve probably never heard a pistol shrimp make a noise unless you spend time near reefs with your head underwater. But the way they catch their prey is pretty interesting. They use bubbles.

By snapping their claws super hard and fast, a pistol shrimp can create a bubble that travels out from their bodies at around 60 mph. That’s enough to stun their prey so they can attack.

But when the bubble pops, it really makes the ocean rock.

Noisy eaters

One specific type of pistol shrimp is known for being a particularly noisy eater (or at least bubble-maker). Synalpheus pinkfloydi is pistol shrimp named after Pink Floyd. Because, hey, why not? We’re pretty sure one of the coolest things about being a scientist is getting to name stuff to your liking.

Anyway, this little shrimp can snap so hard that when it’s bubbles burst the noise can reach up to 210 decibels, according to the Ocean Conservancy (cited below). That’s louder than an actual pistol. Gunshots can reach around 175 decibels.

Clawing their way up the chain of command

The Ocean Conservancy also notes that “The pistol shrimp’s mighty snap comes in handy for more than just lunch. Its powerful claw can deter predators or other competitors looking to take over the shrimp’s burrow. It also makes males more attractive to the ladies—larger claws suggest they are better mates.”

It turns out a good claw is better than a pistol any day!

But it turns out pistol shrimp are also lovers, not just fighters. They work together – even with other species – to help find food and keep their hunting mates safe. So next time you’re hunting in a reef, find a friend with a big claw!

WTF Fun Fact 12751 – Snails Can Sleep For 3 Years

by

You know have knowns snails live their lives at a leisurely pace, but snails can actually sleep for three years at a time!

They’re also hermaphrodites, which means they have male and female reproductive organs, so they don’t even need other snails to mate. They are the ultimate hermits.

But those three-year naps aren’t necessarily a good thing (no matter how comforting they might sound to your right now).

Snails sleep longest in summer

Some snail hibernation is called “estivation.” Hibernation is something that happens when animals sleep to conserve energy in the winter. Snails also sleep in the summer – that’s estivation. Snails can actually do both, but it mostly depends on species or geography (nevertheless, it’s still a skill we’re jealous of).

But why do snails sleep for three years?

Well, not all do. In fact, a three-year estivation typically occurs when the snail’s resources are so depleted that it’s either sleep-or-die. (Yes, we know how relatable this sounds – especially if you have little ones.)

A gooey slumber

Even if snails are estivating for much shorter periods of time, they secrete mucus that covers their whole bodies if the weather is too hot or dry. The mucus helps to protect them from hot or dry weather.

Snails need moisture to survive, so they just provide their own!

Of course, a gooey nap doesn’t protect them from predators thinking they’re dead.

Snail power naps

Snails usually sleep for about 15 hours at a time and then are awake for 30 hours. But that’s under optimal environmental conditions (which are kind of hard to come by these days, no matter what your species.)

This kind of sounds like a productive schedule, if we’re being honest. (Or maybe we could just use a very alert 30 hours to get our work done.)

Beware the sleeping snail

If you think a snail is dead, consider that it may just be taking a power nap. This is especially the case if you keep a snail as a pet. If it is stuck to the side of an aquarium but not moving, it’s likely still alive because it’s secreting mucus to make it stick.

Pet snails are unlikely to hibernate for years (mostly because if humans are providing suboptimal conditions, it’s likely bad enough to just kill the snail).

If the snail’s body is shriveled and dry (if you can see into the shell), then the snail is almost certainly dead (sorry for your loss).

And if you see a snail in the garden, well, that’s up to you and how much you want them around, but crushing it because you think it’s dead could be a deadly mistake for the snail.

WTF Fun Fact 12750 – The Corpus of Galen of Pergamon

by

Galen of Pergamon was a Greek physician working in the Roman Empire in the second century AD. It’s believed he wrote hundreds of treatises. He was a well-known figure in his own time who treated politicians (including Roman emperor Marcus Aurelius) and gladiators alike.

Galen of Pergamon’s treatises

Galen wrote so many medical treatises during his lifetime that had to distill them later on into at least three treatises. He titled these: “On My Own Books,” “On the Order of My Own Books,” and “On My Own Opinions” (the latter only survives in fragments).

He wrote about anatomy and physiology, ethics, pharmacy, medical instruments, hygiene, and even the philosophy of medicine. Much of his work was based on the Hippocratic Corpus. However, he took issue with many of the ideas in those ancient Greek works.

By writing the organizing treatises, Galen meant to set out a curriculum for aspiring doctors. This would allow them to understand the order in which to read his books and what larger philosophical points to take away from each.

Galen outside of medicine

Galen was so prolific that he even wrote on subjects that typically lie outside medicine, such as linguistics. But many of those works are lost and we only know about them via references in other treatises.

Galen is also considered an ancient philosopher and engaged with matter of logic and the texts of Aristotle, Plato, and the Stoics.

Despite all of his medical experimentation and the scientific nature of his writing, he also claimed to have knowledge of medicine thanks to the ancient Greek healing god Asclepius. He also believed that the human body was such a perfect and divine machine that it was certainly created by a greater being. However, he does not engage directly with other metaphysical questions about what else that god might believe or dictate about the world.

WTF Fun Fact 12749 – The Invention of Kidney Dialysis

by

The development of kidney dialysis started centuries ago. Even doctors in the ancient world understood the kidneys played an important role in filtering bodily fluids. Galen’s treatise On the Natural Faculties mentioned doctors prior to his time investigating the organ and its function.

But figuring out how to replicate the filtering function of the kidneys didn’t happen until the 1800s when a Scottish chemist named Thomas Graham realized he could create a membrane to act as a filter to “clean” some bodily fluids (though he wasn’t exactly spot on about what he was filtering out).

Despite sometimes being referred to as the “Father of Dialysis,” his discoveries weren’t kidney-related. In fact, for decades, scientists were more concerned with trying to filter blood for trauma patients during surgery. That’s because they didn’t have blood banks, so when someone lost blood, they needed to preserve it for the patient but also needed a way of cleaning it up first.

Blood dialysis was performed on animals in the early 20th century, and the use of blood thinners was already in use to keep it from clotting (which is necessary if you want to put it back in the body!).

In 1924, a German doctor named Georg Haas realized the possibilities of dialysis for kidney patients. Since our kidneys are responsible for filtering out impurities, those in kidney failure need some extra help.

Haas seems to have had around six patients that used his dialysis machine, but it wasn’t quite ready for prime time yet. All of those patients died of kidney failure (possibly as a result of the dialysis not filtering adequately).

The “drum kidney” was introduced in 1945 by a Dutch doctor Willem Kolff, and because materials science was more advanced, the plastics and other materials he had at his disposal made the machine more effective for cleaning bodily fluids (and didn’t leach its own materials into patients either).

Before we get to today’s modern-day dialysis machines, there were many more people involved in the invention of dialysis – including chemists and physicians that improved upon past technology:

– Swedish chemist Nils Alwall designed a machine to both clean and drain blood
– American scientist Belding Scribner had the dialysis process uninterrupted so the body would not be severely lacking in blood during the dialysis treatment
– Michael Brescia and James Cimino found a way to make Scribner’s invention work with needles so patients didn’t need to maintain an open wound that might be prone to infection

And these are just the preliminary steps we took on our way to modern kidney dialysis!

WTF Fun Fact 12748 – Koala Bears Have Fingerprints

by

Koala bears have fingerprints just like apes and humans. This is surprising since our last common ancestor lived over 100 million years ago.

Nevertheless, koalas have retained their unique fingerprints.

We tend to think of fingerprints as solely a product of our criminal justice system. And yet, those little lines on our fingers actually serve a purpose besides putting us at a crime scene.

The purpose of fingerprints

Our fingerprints help us grab and feel objects, and researchers believe they help our sense of touch. This isn’t so important to us anymore, but it is helpful to animals who can use touch sensations to judge whether leaves, for example, belong to the right tree.

Our fingerprints actually cause little vibrations when we run them over objects. And since koalas really only eat eucalyptus, they like to be sure they’re in the midst of the right kind of buffet before they start chowing down.

Fingerprints are unique

Since you can’t really tell a koala’s fingerprint from a human’s, at least in terms of patterns, they may be the perfect sidekick for a crime scene. There’s no koala bear fingerprint database, so you can pretty much just let them touch everything to upend an investigation (just kidding – don’t try this at home – or anywhere else for that matter).

However, if a koala at a zoo has committed a crime, theoretically, you could fingerprint the residents to figure out whodunnit. We don’t think that’s ever been a necessity, but it sounds like a good premise for a children’s crime novel (if those existed).

Koalas bears have fingerprints and other animals have…

While koala bears have human-like fingerprints, other animals have identifying marks on their paw pads as well.

According to New Scientist (cited below):

Individual cats and dogs, for example, have unique whisker patterns. Zebras have distinct stripe arrangements and individual leopards and spotted dolphins have their own spot patterns. Humpback whales also have unique markings on the underside of their tails.”
