The animal world is full of surprises, with some creatures being more eye-catching than others because of their strange looks or unusual nature.
When I first saw a picture of this weird “penis snake,” I thought it was a joke. But, to my surprise, it turned out to be a real animal. So, let’s dive into the story behind the viral image that has left thousands of people in shock.
Throughout history, anything shaped like a phallus has grabbed attention and sparked curiosity. A few years ago, images of a strange-looking creature started making the rounds online, leaving many people scratching their heads in disbelief.
With its unique appearance, this mysterious animal quickly earned nicknames like the “penis snake,” “blind snake,” or the “man-aconda.”
But no, it’s not what you think.
Even though it looks a lot like a snake, this creature is actually called *Atretochoana eiselti*. It’s not a snake at all, but an amphibian, more closely related to a salamander. It’s also the largest known lungless tetrapod, which means it breathes through its skin instead of lungs.
This rare animal lives in the waters of the Amazon in Brazil and was hard to find for a long time. It was first discovered by Sir Graham Hales during an expedition with Sir Brian Doll in the late 1800s.
However, it wasn’t officially described until 1968. After more research, scientists reclassified it in 1996, giving it its own unique genus, *Atretochoana*.
In 2011, this species was rediscovered in the Amazon region. It lives only in the Amazon River and its largest tributary, the Madeira River in Brazil. The “penis snake” has only been found in this area and nowhere else in the world.
The viral pictures that blew up the internet a few years ago actually came from 2011. That’s when a whole family of these phallic-shaped creatures was found at the bottom of the Madeira River in Brazil. They were discovered when the river was drained during work on a hydroelectric dam.
Julian Tupan, a biologist working with the Santo Antonio Energy company on the dam, explained that not much is known about these lungless, limbless amphibians.
“Out of the six we collected, one died, three were released back into the wild, and two were kept for study,” he told *Estadao*, according to the U.K.’s *The Sun*.
Tupan pointed out that these “snakes” aren’t dangerous and are unlikely to show any aggressive behavior.
“Even though they look like snakes, they’re not reptiles; they’re more closely related to salamanders and frogs. We think the animal breathes through its skin and probably eats small fish and worms, but that hasn’t been proven yet.
“The Amazon is full of surprises when it comes to reptiles and amphibians. There’s still a lot more to discover.”
According to a paper published in the Brazilian scientific journal *Boletim do Museu Paraense Emílio Goeldi: Ciências Naturais*, one of these creatures found in the riverbed was photographed extensively. Some of the animals were released back into the Madeira River, while others were sent to the Emilio Goeldi Paraense Museum in Belem, Brazil.
The most popular photo, which Julian Tupan shared on Instagram, shows an adult female *A. eiselti* that’s just under 40 inches long.
Even though these creatures are fascinating, there’s still a lot we don’t know about them. One mystery that puzzles researchers is their diet. Scientists think these phallic-shaped animals might eat small fish, worms, and other aquatic invertebrates, but more research is needed to confirm this.

Another mystery about these creatures is how they breathe, as scientists haven’t confirmed the method yet. When the six specimens were discovered in 2011, it made things even more puzzling. What’s especially interesting is where they were found— in cold, fast-flowing water with limited oxygen. Since warmer water holds less oxygen, their ability to live without lungs is even more remarkable.
Based on these findings, scientists believe this species might be widespread across the Brazilian Amazon and could even extend into Bolivia.
Nature constantly surprises us with its endless wonders. From the deepest oceans to the tallest mountains, the natural world is full of amazing things waiting to be discovered.

Matthew McConaughey says Woody Harrelson might be his brother after a confession from his mom.

Matthew McConaughey and Woody Harrelson are famous actors who have been in the spotlight for many years. They’ve been close friends and even starred together in the popular show “True Detective” in 2014, where their on-screen chemistry felt like a brotherly bond.
It turns out, their connection might be deeper than just friendship. Could their realistic performances have been influenced by a truth they didn’t know at the time?
According to McConaughey, he and Woody Harrelson might actually be real brothers. Not just close friends or like brothers, but actual brothers by blood.
According to Metro, McConaughey says he and Harrelson might be siblings. His mom revealed something that makes this hard to ignore.
McConaughey, who is 53 and starred in “Dallas Buyers Club,” said his mom hinted she knew Harrelson’s father well, suggesting they might have had a close relationship in the past.
McConaughey shared on Kelly Ripa’s Let’s Talk Off Camera podcast that his mom dropped this surprising news while his and Harrelson’s families were on vacation in Greece together.

The Interstellar actor shared that one day they were talking about how people often confuse him and Harrelson in photos.
“A few years ago in Greece, we were sitting around talking about how close we are and our families,” McConaughey said.
“My mom was there and she said, ‘Woody, I knew your dad.’ Everyone noticed the pause after ‘knew.’ It was a loaded K-N-E-W.”
After hearing this, McConaughey decided to investigate his family history. He found out that while his parents were going through their second divorce, Harrelson’s father was on furlough.

Harrelson, who is 63, suggested they get DNA tests, but McConaughey isn’t sure.
McConaughey said, “It’s easier for Woody to say, ‘Let’s do DNA tests,’ because he doesn’t have much to lose. For me, it’s harder because it might mean that my dad isn’t really my dad after believing that for 53 years. I have more at stake.”
Harrelson’s father was sentenced to 15 years in prison in 1973 for murdering a grain dealer, which Harrelson learned about from a radio broadcast.
The Hunger Games star told The Guardian: “I was waiting in the car for someone to pick me up from school. I was listening to the radio, and they were talking about a trial involving someone named Charles V Harrelson for murder. I thought, ‘There can’t be another Charles V Harrelson. That’s my dad!’”
