Lumpeguin

Tradition / Region: Wabanaki Mythology, American Mythology
Alternate Names: Lampeqin, Lampekwin, Lumpegwen, Lumpeguinuwok (plural)
Category: Mermaid


The Myth

In the rivers and coastal waters of Wabanaki lands dwell the Lumpeguin, small and powerful water spirits. Some say they appear as little people with shining eyes and long hair dripping with river water. Others say they are like tiny mermaids, with human faces and fish tails flashing silver beneath the surface. They move easily between water and shore, belonging fully to neither.

The Lumpeguin are beings of quiet magic. They can multiply food from almost nothing. A scrap of bread may become a feast in their hands. A handful of snow may be baked into warm loaves. Some carry enchanted pots that never empty, feeding those they favor. Their gifts, however, are never given lightly.

Like many nature spirits, a Lumpeguin’s power is bound to a magical garment—an article of clothing that allows them to move between worlds. If that garment is stolen, the Lumpeguin falls under the power of the thief. In old tales, men—and sometimes even animals—have hidden these garments and forced Lumpeguin women to remain on land as wives. Though they may live for a time among humans, their hearts remain with the water. If they ever recover their hidden clothing, they return at once to the rivers and are never seen again.

One tale tells of two Lumpeguin sisters who were captured in this way by Marten, a clever forest being. He hid their magical garments and claimed them as wives. The sisters lived with him, but they did not forget who they were. Through patience and cunning, they eventually regained their garments and set off on journeys of their own, traveling through forest and water alike, neither fully captive nor fully free until they reclaimed their power.

The Lumpeguin remind those who hear their stories that the spirits of the rivers cannot be possessed without consequence. Water gives life and sustenance, but it belongs first to itself. Those who try to bind it may hold it for a while—yet in the end, it always slips back to its own depths.

Stia

Tradition / Region: Macedonian Mythology
Alternate Names: Стија
Category: Mermaid


The Myth

In the deep lakes of Macedonia dwell the stia—mysterious female beings who are half woman and half fish. Their long hair flows like river weeds in the water, and their tails shimmer beneath the surface like the scales of a great silver carp.

The stia rarely reveal themselves to humankind. By day they remain in the dark, silent depths, where sunlight cannot reach. There, among sunken stones and drowned branches, they gather and drift like pale shadows. But when the moon rises and lays a path of silver across the lake, they rise closer to the surface.

Fishermen tell of hearing soft singing carried over still water on windless nights. Those who follow the sound may glimpse a pale face rising from the lake, framed in long, wet hair. Some say the stia watch quietly from the reeds, their eyes shining just above the surface before slipping away without a ripple.

They are said to guard the hidden places of the lake—the deepest hollows and coldest springs. Anyone who ventures too far into their waters, whether out of greed or arrogance, risks being drawn downward. A sudden tug at the ankle, a swirl of water where none was before, and the lake closes again as if nothing had happened.

Yet the stia are not always cruel. In some tales, they have been seen weeping beside the bodies of drowned youths, combing their long hair in sorrow. Others say they sometimes guide lost children back toward shore, pushing them gently with unseen currents.

Beautiful, distant, and dangerous, the stia belong to the still waters and moonlit depths, where the boundary between the human world and the hidden world beneath the lake grows thin.

Namiko

Tradition / Region: Japanese Mythology
Alternate Names: Girl of the Sea
Category: Mermaid


The Myth

During one summer in Kamakura, a clever but willful girl named Namiko went to stay near Yuigahama Beach while her sick mother rested in a hospital nearby. Though she excelled at school, at home she was stubborn and often caused her father trouble with her selfishness.

One day, while playing alone on the shore, Namiko encountered an old woman selling fish. Among the catch was a beautiful striped sea bream, its scales gleaming in the sunlight. Entranced by its natural beauty, Namiko declared that she wished she could be as beautiful as that fish.

The old woman laughed.

“A kimono fades and wears out,” Namiko insisted. “But a fish’s beauty never falls away. If I were as beautiful as that, I would never lose it.”

“Then become a fish,” the old woman said, her eyes sharpening.

“Yes, I would!”

At once the old woman’s laughter ceased. She chanted a strange sutra, and before Namiko could protest, she was transformed into a striped sea bream. The fish-seller’s true form was that of a powerful magician.

Thrown into the sea, Namiko swam bewildered through the underwater world. At first, she was amazed by the shimmering waters and the strange creatures gliding past her. It felt like exploring a living aquarium. But as the currents grew rough and hunger gnawed at her, she was forced to eat small fish she once would have admired. She could not cry; fish have no tears. Loneliness overtook her, and she longed for her parents.

Resting against a rock on the ocean floor, she lamented her foolish words. “All I did was stubbornly wish to be a fish.”

Meanwhile, on the shore, her father and their maid searched desperately. When they found her clothes abandoned on the beach, they believed she had drowned. Their grief was unbearable.

Then the old woman appeared before them.

“Your daughter lives,” she said calmly, and instructed Namiko’s father to take a boat out to sea the next morning.

At dawn, they followed her directions. Pointing to a struggling striped sea bream in the waves, the old woman declared, “That fish is your daughter.”

Understanding that this had been a lesson for his child’s stubborn pride, Namiko’s father fell to his knees and begged the magician to restore her.

As he lifted the sea bream into his arms, the old woman once again chanted her spell. The fish began to grow, its head transforming first, then its body, until Namiko stood once more in human form. Father and daughter embraced in tears, and Namiko vowed never again to let selfish pride rule her heart.

The magician suddenly vanished.

Then a voice drifted down from the sky. The old woman spoke, saying that though she had once used magic to torment many, she had now redeemed herself by correcting Namiko’s ways. Her sins were forgiven, and she would ascend to heaven.

She warned of a coming storm and asked Namiko to send down five-colored thread from the shore.

That afternoon, as winds rose and the sky darkened, Namiko kept her promise. A five-colored thread was cast toward the sea. From the heavens, the old woman—now transformed into a dragon—received it as she ascended.

After that day, Namiko treated her parents with devotion and filial piety. Her mother recovered from illness, and peace returned to their home.

And by the sea at Yuigahama, people remembered the tale of the girl who became a fish—and the dragon who rose to heaven.

Merrow

Tradition / Region: Irish Mythology
Alternate Names: Murdúchann, Muirgheilt, Maighdean mhara
Category: Mermaid


The Myth

Along the rocky coasts of Ireland, where grey waves strike the cliffs and sea-mist hangs in the air, the merrows dwell beneath the waters.

They are sea-people—half human, half fish. From the waist upward, the merrow-maiden appears as a beautiful woman, with pale skin and long green hair that she combs as she sits upon lonely rocks. From the waist downward, she bears the scaled tail of a fish, shimmering with a greenish sheen. Between her fingers lies a delicate webbing, fine as the skin within an eggshell.

But a merrow cannot freely pass between sea and land without her magical cap—the cohuleen druith, a little enchanted hood. With it, she may dive to the deepest waters or rise to the shore. Without it, she is bound to whatever realm she stands upon.

Many tales tell of fishermen who glimpsed a merrow combing her hair at dusk. Some men hid her magic cap and so prevented her return to the sea. Bereft of it, she became their wife. She bore children, tended the hearth, and lived gently among the people. Her nature was said to be affectionate and kind, capable of loving a mortal man.

Yet no matter how long she remained, the sea called to her.

If ever she found her hidden cap, her longing for the deep would overcome all earthly bonds. She would take it, kiss her children, and vanish into the waves, never to return. The sea was her first home, and it would not release her forever.

The merrow-men were another matter. Unlike the maidens, they were said to be grotesque—green-haired, red-nosed, sharp-toothed creatures with pig-like eyes and scaly limbs. Some were known to dwell in houses beneath the sea, where drowned sailors’ souls were kept like treasures in cages. They loved strong drink and strange company, and though fearsome in appearance, they too belonged to the same hidden kingdom under the waves.

The music of the merrows sometimes rises from the ocean depths. It drifts across the surface like a distant song—sweet, haunting, and perilous. Those who follow it may never return.

In older tales, the murdúchann appeared as sea-singers, akin to sirens, whose melodies enchanted sailors. In still other legends, sea-wanderers such as Lí Ban were transformed into fish-tailed beings, destined to roam the waters between worlds.

Thus the merrow stands at the meeting of land and sea—beautiful yet sorrowful, loving yet unbound, forever torn between hearth-fire and tide.

Jinja hime

Tradition / Region: Japanese Mythology
Alternate Names: Hime uo (Princess Fish)
Category: Mermaid, Yokai


The Myth

In the year 1819, on a lonely shore in Hizen Province, an unusual creature was seen upon the sand.

It was long and serpentine, nearly six meters in length. Two horns rose from its head. A dorsal fin ran along its back, and flippers lay against its sides. Its tail stretched behind it like that of a great sea serpent. Yet its face was not that of a fish. It was the face of a woman.

The creature spoke.

“I am a messenger from Ryūgū,” she said, naming the palace of the Dragon King beneath the sea. “My name is Jinja hime.”

She declared that for seven years the land would enjoy abundant harvests. Rice would grow thick and heavy; the people would prosper. But after those seven years, a great sickness would spread across the country—an epidemic that would bring suffering and death.

Yet she offered hope.

“Those who look upon my image,” she said, “will avoid hardship and be granted long life.”

Having delivered her prophecy, the shrine princess slipped back into the sea and vanished beneath the waves.

Her likeness was drawn and shown to the people, so that they might gaze upon it and be protected. The image spread from hand to hand. Fishermen, farmers, and townsfolk spoke of the sea princess who foretold both blessing and plague.

From that time on, stories began to circulate across Japan of other strange beings who emerged from the sea or the mountains to warn of disaster and promise protection through their image.

But it was Jinja hime—the shrine princess of the deep—who first rose from the waters, spoke of fate, and returned to the palace of the Dragon King below.

Akugyo

Tradition / Region: Japanese mythology
Alternate Names: Daigyo; Raichōgyo
Category: Fish, Mermaid, Yokai


The Myth

In the seas near Kibi Province, sailors spoke in fear of the Akugyo, the Evil Fish. Vast beyond measure, it rose from the depths to overturn ships as easily as toys, devouring the sailors who fell screaming into the water.

Some Akugyo breathed fire from their mouths, scorching ships before dragging them under. Others resembled enormous ningyo, their bodies covered in gold and silver scales that gleamed beneath the waves. There were also Akugyo shaped like colossal mermaids, bearing two white horns like those of an oni sprouting from their heads. Fishermen dreaded these monsters, for a boat could become trapped between the creature’s massive fins, leaving the crew helpless as the Akugyo fed.

In the sixth month of 1805, an Akugyo appeared off the coast of Echigo Province. Its body stretched more than eleven meters in length, and its horns were longer than a man’s arm. The terror it caused was so great that the Lord of Kaga dispatched a vast force—fifteen hundred men and four hundred fifty cannons—to hunt it down. After a great battle at sea, the monster was finally slain.

Another tale tells of Izutsuya Kanroku, a famed taiko drummer from Kaga. While crossing the Sea of Japan, his boat suddenly came to a halt. Beneath it lay the back of an Akugyo, and the vessel had become lodged upon the monster’s body. Believing death inevitable, Kanroku took up his drum and played with all the strength he had left. His drumming thundered across the sea and sky, echoing like a storm.

Moved—or perhaps startled—by the sound, the Akugyo shifted. The boat slipped free, and Kanroku escaped unharmed.

Thus the Akugyo remains a creature of terror and wonder: a destroyer of ships, yet sometimes driven away by courage, sound, and human resolve.

Renyu

Tradition / Region: Chinese Mythology
Alternative names:
Category: Fish, Mermaid


The Myth

In ancient times, strange beings known as renyu, or human-fish, were said to live in rivers, seas, and distant waters across the world. These creatures were neither fully human nor fully fish, but something in between. They appeared in many regions, especially in remote mountains and waterways where ordinary people rarely traveled.

Some renyu were described as fish with human features, while others had four legs and moved like animals on land. Their voices were said to sound like crying infants, a sound that echoed eerily across rivers and valleys. Though strange and unsettling, renyu were not always hostile. In certain places, eating the flesh of a renyu was believed to cure illnesses of the mind, restoring clarity and reason to those afflicted.

One well-known renyu lived in the Bursting River near Dragon-Marquis Mountain. This creature resembled a large fish, yet possessed limbs and a human-like voice. It lingered in deep waters, surfacing only rarely. Those who heard its cry often mistook it for a child in distress.

Renyu were also said to produce a mysterious oil. This substance burned with an unusually steady flame, and lamps fueled by it were believed to last for an exceptionally long time. Because of this, renyu oil was treasured and used in sacred and imperial places.

Stories also tell of female renyu who appeared as beautiful women living on remote islands or cliffs by the sea. These beings could take human form and live among people. In one tale, a man married such a woman, lived peacefully with her, and fathered children. She protected him, taught him survival skills, and shielded him from danger. But when the man was taken away from the island against his will, the renyu revealed her true nature in grief and fury, casting their children into the sea and vanishing forever.

In another story, a traveler was captured by two mysterious women on an island. They fed him daily and kept him alive, yet he felt suspended between life and death. When he learned too much about their hidden powers, they fled into the sky, abandoning him. Though he escaped, he weakened and died soon after, unable to return fully to the human world.

Renyu were also known by other names, such as child-fish, reflecting both their voices and their unsettling resemblance to human infants. Some lived in rivers, others in the sea, and each variety possessed different forms and powers. All were regarded as beings that blurred the boundary between human and animal, land and water, life and death.

In legend, the renyu are reminders of a world where the natural and supernatural were deeply intertwined—where rivers spoke, fish cried like children, and the sea concealed beings who could heal, deceive, or destroy.
