Life in the Amazon River: Freshwater Stingray

Making the change from ocean to lake should be relatively easy, right?
You’d think the raging high seas would be a much tougher place to survive than the calm waters of a freshwater lake or river. Making the change from ocean to lake should be relatively easy, right?
Well, that’s not necessarily the case, let’s dive deeper into the biology and chemistry to uncover the answer!
Outstanding Osmosis
The bodies of ocean animals are packed with a lot of salt. When you move them to a body of freshwater with a much lower concentration of salt relative to their bodies, osmosis kicks in.
Osmosis involves the bidirectional movement of water in and out of an animal’s body, from an area of high concentration to an area of low concentration. This delicate balance between salt and water within an animal’s body is known as osmoregulation.
Just like when we breathe, osmoregulation doesn’t require the animal’s active thought but is vital for their survival. This means if you were to put an ocean animal into a freshwater system it would be fatal as water would come rushing into it’s cells causing it to swell and burst.

How Do They Survive Today?
If you were to ask a general audience to describe the rivers of the Amazon, it is likely that a few people would mistake it for an ocean. This isn’t much of a surprise as the Amazon Rainforest ecosystem is teeming with animals typically associated with the ocean, including pink dolphins, needlefish, and stingrays.
So how are these creatures thriving today if marine life can’t survive in freshwater systems?
The answer is in the perfect conditions that must have existed 10 million years ago to make way for this new wave of life. Melting sea ice caused sea levels to rise, effectively drenching the entire upper Amazon with saltwater and life from our oceans.

Pebas Mega Wetland
This area is known as the Pebas Mega Wetland and covers what we know today as Brazil, Peru, Ecuador, and Columbia. This brackish (a mix of salt and freshwater) region once home to 11.8 metre or 39-foot crocodiles and behemoth sized-turtles becoming the perfect grounds for evolution.
The formation of the Andes Mountain range within the Pebas Mega Wetland was the main tectonic event that would change biology forever.
The emergence of this physical barrier, cut off freshwater rays from their ocean cousins and overtime, the saltwater lakes slowly turned to freshwater. This slow change in salinity means avoiding the osmosis problem and allows for the animals to adapt and evolve as necessary.

Extraordinary Evolution
Evolution doesn’t occur overnight but rather over the course of millions of years where individuals that are more adapted to their environment have a higher likelihood to survive and pass on their genes that led to their success. Overtime, these adaptations show themselves very clearly as we can see today in the appearance of freshwater rays found within South America.
Whether it is the ocellate river stingray (Potamotrygon motoro) or white blotched river stingray (Potamotrygon leopoldi), these freshwater stingrays are now a whole different genus from their saltwater counterparts.

How Habitats Play a Role
Freshwater habitats differ drastically from the open ocean which would explain the stark contrast in their appearance. The murkier waters and darker coloured substrate (branches, logs, leaves) found along the bottom here would also account for the array of appearances and body types we see in this region.
Tiny spots, marbled swirls, and different jaw shapes had all emerged by the end of the Miocene 5 million years ago within these isolated populations. There was even a study conducted where the team analyzed the jaws of different stingrays in the region. Not only did they find a difference in physical appearance in these rays, but a difference in jaw shape and size. This was a result of rays specializing and adapting to different kinds of prey that they now had available.
Some rays have evolved mouths with fewer teeth and more jaw gaps to allow them to suck up fish quickly. Other rays had evolved much longer mouth bones to crush the hard shells of crustaceans. Another group of rays evolved kinetic jaws which allowed them to chew the tough exoskeletons around insects.

Succesful Adaptation
Each one of these respective specializations, allowed for the rays to dominate their environment. Interestingly, the ocellate river stingrays are actually a generalist, their ancestors didn’t hone in on one type of prey but still managed to be quite successful and that is why they can be found all over South America today.
Sadly, the rays in South America are facing many issues today that they have not had to before. If we don’t do our part to keep our habitats clean, these lovely creatures will likely become extinct.

A Functioning Theme Park... 400 Feet Underground: From Salt Mine to Theme Park

Here at Ripley's, we've uncovered attractions in some strange places... but this one takes fun to a whole new depth.
Hidden beneath the surface of Romania lies Salina Turda, an underground playground carved deep inside one of the world’s oldest salt mines. Visitors descend nearly 400 feet below Earth’s surface to explore a place where history and fun collide.
From Salt Mine to Theme Park
More than 2,000 years old, Salina Turda once produced over three billion tons of salt. Over time, the massive excavation created a cavern so enormous it could hold an entire theme park, and now, it does.
Deep below ground, visitors can enjoy:
• A full-size Ferris wheel
• Mini-golf and bowling
• An underground lake where you can row a boat
• Towering salt walls that make every activity feel otherworldly
You can reach the bottom by elevator, or take the long staircase if you’re up for the workout.
A Playground Like No Other
This isn’t just an attraction; it’s a reminder that humans have a talent for turning the unexpected into something unforgettable. What was once a working salt mine is now one of the strangest theme park destinations on the planet. Would you visit?

Ripley’s Very Own Olympic Games

For a genuinely unbelievable Olympics, only the weirdest sports will do…
The original Olympic Games were the brainchild of the ancient Greeks. Competitions focused on athletic endeavors and military pursuits and were designed to unite disparate Greek city-states. Early sports included footraces, javelin throwing, discus throwing, wrestling, and boxing.
So, what might a weird and wacky Ripley’s version of the games look like? Let’s dive into a list of wild and bizarre events we’d like to see in the lineup.

Outhouse Racing
For the past 35 years, Virginia City, Nevada, has hosted one of the planet’s strangest sporting events-The World Championship Outhouse Races. As the name suggests, the competition involves creating extravagant, over-the-top outhouses.
These are paraded through the Wild West town. Next, contestants line up to full-bore, sprint-push their wheeled loos down the main thoroughfare of C Street. The result isn’t potty, but we can’t think of a more eclectic competition for our outlandish Olympics!

Toe Wrestling
Is the thought of thumb wrestling in the Olympics laughable to you? We say, “Meh.” Instead, consider the edgy, envelope-pushing, glorious sport of toe wrestling. Completely unfathomable? Perhaps. Totally incomparable? Absolutely! That’s why this chart stopper makes our list of corn-y competitive sports.
Invented in 1976 in Derbyshire, United Kingdom, two opponents lock toes, with the winner pinning the other’s feet. Although the competition sounds laughable, it gets serious quickly. Competitors must approach it with a callused resolve to win despite broken toes, drawing blood, and scraped knees! So, “tootsie” wrestling wannabes beware.

Chessboxing
Mix brains and brawn through the fine sport of chessboxing. A hybrid of two of humanity’s oldest sports, players compete on the board before heading into the ring to slug it out. Rounds alternate between both pursuits, providing a mindboggling form of entertainment.
Invented by Enki Bilal, a French comic book artist, and adapted by Iepe Rubingh, a Dutch artist, chessboxing started as performance art. But today, it continues to grow in legitimacy and popularity. When it comes to the oddball Olympics, we say, “Why not?”

Wife Carrying
The name says it all regarding the ancient sport (or is it an art?) of wife carrying. A staple of Finnish recreational life, male contestants complete an obstacle course as fast as they can while their wives cling to their backs. How does the carrying work? It depends on your preference.
Several carrying positions are permitted. They include the classic piggyback style, a fireman’s carry (over the shoulder), and the so-called Estonian style. (Basically, the wife hangs upside down bat-style with her legs over the neck and shoulders of her husband.) Winners of the competition garner the weight of their wives in beer. But we hope gold will be an acceptable alternative.

Zorbing
What’s zorbing? It involves hurtling down a mountain face inside a giant, transparent, plastic orb. Or, walking on water in one of these big hamster balls. The first zorbing site appeared in New Zealand, and these spheres have become staples of theme parks across the United Kingdom and the United States.
To date, the fastest zorbing athlete remains New Zealand’s Keith Kolver. He reached a whopping 32 miles per hour in a plastic ball! As for the longest distance? Steve Camp of South Africa traveled 1,870 feet in one. Clearly, there’s plenty of room for new records and a ready supply of (at least two) competitors to ball up. Best of all, athletes are known as “zorbonauts,” which is its own kind of cool!

Haggis Hurling
Let’s face it. Scotland boasts many bizarre sports, from the caber toss to stone skimming. But haggis hurling takes the cake. It involves chucking a sheep’s stomach-stuffed with various sheep organs, onion, oatmeal, spices, and suet-inhuman distances.
Whether for better or worse, it reemerged as a sport in 1977 during a Gathering of the Clans. Today, there’s even a World Haggis Hurling Association to ensure athletes toss their cookies properly. Nothing says international competition like edible sheep guts flying through the air. Let the hurling begin!

Hot Dog Eating Championships
Annually, on July 4, Nathan’s Famous Hotdog Eating Contest takes place on New York’s Coney Island. During the competition, participants aim to suck down as many dogs as possible in ten minutes. Some competitors reach astronomical numbers.
How many wieners are we talking about? Current champs include Joey Chestnut at 62 sausages and Miki Sudo at 39.5 weenies. More than 35,000 people flock to the event annually, and millions more tune in via ESPN. In other words, this peculiar event comes with a ready-made audience of devoted fans.

Unicycle Hockey
Field hockey requires skill and coordination as anyone who’s ever played can attest. After all, getting the hang of passing a puck with a hockey stick is …. well, challenging. Add ice skates to the mix, and you’ve got next-level crazy.
But some folks don’t think that’s enough difficulty. So, they’ve pushed the envelope astronomically with unicycle hockey. Swap out skates for a unicycle, and things snowball in difficulty! What’s even harder than playing unicycle hockey? Trying to keep a straight face while watching competitors wobble and whack away at the puck. (In this case, a tennis ball.)

Cardboard Tube Fighting
The Cardboard Tube Fighting League (CTFL) is an international organization that holds cardboard tube-based tournaments across the American West Coast and Australia. These competitions involve fighters decked out in cardboard armor and wielding cardboard tube weapons. Winners aim to break their opponent’s cardboard tube while keeping their own intact.
Cardboard tube fighting is evocative of the original Olympic Games, which focused on athletic and militaristic pursuits. We can only imagine what Ancient Greek athletes would have done if they had been gifted with the technological innovation that is cardboard. (Bye bye, Bronze Age!) Besides channeling the original games’ competition, cardboard tubes could even provide an elegant, though fast-burning, solution for the Olympic torch!

Sepak Takraw
What happens when you cross kickball and volleyball? Something known affectionately as Sepak Takraw. Imagine two teams coalescing on a badminton-style court with a volleyball-type net to kick a softball-sized implement back and forth like martial artists. (Repeat that three times fast!) The implement is made of rattan or synthetic plastic and may touch the players’ knees, feet, shoulders, head, and chest. But hands are totally off-limits.
Teams of three players face off. How do they score? By landing the ball on the opponent’s side. Standardized in 1960, the sport is considered a cross between volleyball and soccer. Sepak Takraw is governed by the International Sepaktakraw Federation (ISTAF) and is played in Singapore, Malaysia, Thailand, and Myanmar. We say this hybridized sport is the perfect addition to an off-the-wall Olympics.
