Let’s be real for a second. We’ve all been conditioned by decades of red-haired princesses and singing crabs to think that living under the sea is some sort of aquatic utopia. It isn't. If you actually look at the source material—the gritty, brine-soaked folklore that existed long before corporate animation got its hands on it—you’ll realize pretty quickly that mermaids are the worst. They aren't your friends. They aren't looking for love. Most of the time, they’re just looking for a snack, and unfortunately, that snack is usually a sailor named Barnaby who just wanted to get home to his family.
History is messy. Mythology is messier.
When you dig into the archives of maritime history and global folklore, the "mermaid" isn't a singular entity. It’s a terrifying archetype. From the Scottish Highlands to the coast of Africa, these creatures represent the unpredictable, often lethal nature of the ocean. It’s kinda funny how we’ve turned a symbol of impending doom into a birthday party theme for toddlers. Honestly, if you encountered a "real" mermaid based on the original legends of the Atargatis or the Slavic Rusalka, you wouldn't be looking for a fork to brush your hair. You’d be praying for a fast boat and a miracle.
The Brutal Reality of the Original Little Mermaid
Hans Christian Andersen gets a lot of the blame for the modern obsession, but even his 1837 story was a nightmare compared to the movie. People forget that. In the original text, every step the mermaid took on her new human legs felt like walking on sharp knives. It was constant, agonizing pain. She didn't just lose her voice; she had her tongue cut out. And the ending? No wedding. No happily ever after. The Prince marries someone else, and the mermaid is told she has to stab him in the heart so his blood can drip on her feet to turn her back into a fish.
She chooses to dissolve into sea foam instead. It’s bleak.
This isn't just "sad" storytelling. It’s a reflection of how traditional folklore viewed these entities as fundamentally incompatible with the human world. They belong to the "Other." When we try to bridge that gap, things break. The ocean is a graveyard, and in many ways, the mermaid is its primary gatekeeper.
Why the Siren Myth Proves Mermaids Are the Worst
We often mix up Sirens and Mermaids. Technically, early Greek Sirens were half-bird, but over centuries, the imagery merged into the fish-tailed women we know today. Whatever the anatomy, the result was the same: death.

Take a look at Homer’s Odyssey. The Sirens didn't lure men because they were lonely. They did it to cause shipwrecks. They sat on a pile of rotting corpses and sang songs that stripped men of their free will. It’s a predatory relationship. There’s no nuance there. In the Physiologus, an early Christian text that influenced a lot of medieval beastaries, the mermaid is described specifically as a deceptive creature. She uses her beauty to lull sailors to sleep before tearing them apart.
- The Melusine of European folklore had a double tail and a habit of bringing misfortune to the noble houses she married into.
- In the Shetlands, Finfolk were known to kidnap humans to take as "spouses" against their will, keeping them in a dreary underwater city called Finfolkaheem.
- The Rusalka of Slavic myth were the spirits of young women who died violently; they spent their afterlives drowning men who dared to come near their rivers.
These aren't just "misunderstood" girls. They are personifications of the sea's ability to kill you without a second thought.
Environmental and Biological Horrors
If we step away from the magic for a moment and look at the "biology" of a mermaid, the logic falls apart in the most disgusting ways possible. If you’ve ever smelled a fish market on a Tuesday afternoon in July, you know exactly why mermaids are the worst neighbors.
Think about the physiology. A human torso attached to a large fish tail would require a massive amount of caloric intake just to maintain body heat in the deep ocean. We’re talking blubber. Lots of it. A "realistic" mermaid wouldn't look like a supermodel; she’d look like a leopard seal with hair. She’d be covered in sea lice and parasites. There’s no way around it. The logistics of underwater survival are brutal.
Furthermore, the "voice" we all admire? In reality, sound travels differently underwater. To be heard across the surface, a mermaid would likely need to emit high-frequency screeches or low-frequency thumps similar to whale vocalizations. Imagine a beautiful woman opening her mouth and sounding like a malfunctioning sonar ping. It’s less "Part of Your World" and more "Eldritch Horror."
The Psychological Toll of the "Idealized" Mermaid
There is a weird cultural obsession with the mermaid as an icon of freedom. We see them as "wild" and "untamed." But this romanticization ignores the fact that, in almost every piece of folklore, the mermaid's interaction with the human world ends in tragedy for everyone involved.

Take the Selkie legends from Ireland and Scotland. While not strictly "mermaids" (they are seals that shed their skin), the stories follow the same beat. A man steals a Selkie's skin, forces her to marry him, and she spends years in a state of mourning until she can find her skin and escape, leaving her children behind. It’s a cycle of trauma. By turning these creatures into "waifish" beauties who just want to be loved, we strip away the terrifying power they were supposed to represent. We’ve neutered the monster, but the monster’s shadow still looms over the history of the deep.
Global Variations of the "Worst" Mermaids
If you think the Western versions are bad, the rest of the world has some even more terrifying takes.
In Japan, the Ningyo is far from a beauty. Early depictions show them as creepy, fish-like creatures with human-ish faces and sharp teeth. Catching one brought storms and bad luck. Eating one’s flesh could grant you eternal life, but it usually came with a side of misery and the death of everyone you ever loved. It wasn't a gift; it was a curse.
In parts of Africa, Mami Wata is a powerful water spirit. She can bring you immense wealth, sure, but she’s also notoriously jealous. If you don't follow her strict (and often impossible) demands, your life will fall apart. She isn't a pet. She’s a deity that demands total submission.
Then you have the Qalupalik of Inuit mythology. These are sea-creatures with long fingernails and green skin who wear "amauti" (a type of parka) so they can kidnap children who wander too close to the ice. They don't want to sing to you. They want to put you in a bag and take you to the bottom of the ocean forever.
Why We Keep Looking at the Water
So why do we keep pretending? Why do we ignore the fact that mermaids are the worst?

Probably because the ocean is the last great mystery on Earth. We’ve mapped the moon, but we barely know what’s happening at the bottom of the Mariana Trench. We populate that void with things that look like us because the alternative—that the ocean is just a vast, cold, indifferent expanse of water—is too scary to handle. We’d rather be hunted by a beautiful monster than realize we’re just irrelevant to the deep.
How to Spot a "Classic" Mermaid (And Why You Should Run)
If you happen to find yourself on a rocky outcrop and see something shimmering in the distance, don't reach for your camera. Folklore gives us plenty of warning signs that you’re dealing with a predatory entity rather than a Disney princess.
- The Mirror and the Comb: In medieval British folklore, a mermaid is almost always seen with a mirror and a comb. This wasn't just vanity; it was a sign of her "otherness." If she’s grooming herself, she’s likely preparing for a hunt.
- Sudden Calm Weather: Mariners used to believe that seeing a mermaid was a sign of a coming storm. The "calm" was just the lure.
- Unnatural Beauty: If she looks too perfect, she probably isn't. Many legends suggest that their "beauty" is a glamour, a magical mask used to hide a much more horrific, predatory form.
Actionable Steps for the Folklore Enthusiast
If you want to move beyond the sparkly stickers and actually understand the dark history of the deep, you need to go to the sources. Stop watching the reboots and start reading the actual transcripts of maritime legends.
- Read "The Shadow Over Innsmouth" by H.P. Lovecraft: It’s the ultimate "mermaids are actually terrifying" story. It deals with the Deep Ones, a race of amphibious humanoids that are anything but friendly.
- Study the "Physiologus": Look for translations of medieval bestiaries to see how religious scholars viewed the mermaid as a symbol of temptation and sin.
- Visit Maritime Museums: Places like the National Maritime Museum in London have incredible archives on sailor superstitions and the "sightings" that fueled these legends for centuries.
- Analyze Biological Parallels: Look into "Manatee sightings" by explorers like Christopher Columbus. He famously noted that the "mermaids" he saw weren't as beautiful as they were painted and actually looked quite masculine. It’s a great lesson in how expectation colors reality.
The ocean is a dangerous place. It’s cold, it’s high-pressure, and it’s full of things designed to eat you. Adding a half-human predator to that mix doesn't make it magical; it makes it a horror movie. Respect the water, but don't trust the things that claim to live in it.
The next time you see a "mermaid" tail splashing in the surf, don't wait around for a song. Just walk away. Your life—and your lack of sea-lice—will thank you.
