Selkies are seal people of the folklore of the North Atlantic: seals in the sea that can take off their skins and walk ashore as human beings. They belong above all to the Northern Isles of Scotland, Orkney and Shetland, where hundreds of stories were collected, but similar seal-folk traditions are found in the Hebrides, Ireland, the Faroe Islands and Iceland. The best-known story, of a man who steals a seal woman’s skin and keeps her as his wife until she finds it and returns to the sea, is one of the most widespread folktales in northern Europe. Selkies are not a cryptid in the sense of an unknown animal; they are a folklore tradition about a very real animal, the seal, and the people who lived alongside it.[1][2]

Where the word comes from
Selkie is a Scots word, a diminutive of selch, meaning “seal.” The Dictionary of the Scots Language traces selch to Old Scots selich, matching Old English seolh, the source of modern English “seal.” The selkie forms (also spelled silkie, sejlki and sulky) are chiefly found in Shetland, Orkney and Caithness, and the dictionary records “selkie folk” as a sea-dwelling race resembling seals but able to take human form. Strictly, selch refers to the grey seal; the folklorist Alan Bruford argued that “selkie” should be understood as any seal, whether or not it was thought to transform.[1][2]
In Orkney tradition, only seals larger than the ordinary grey seal were credited with the ability to change shape. Large Arctic visitors such as the harp seal and the hooded seal, occasionally seen in the islands, may have contributed to that idea. In Shetland, the sea people were said to prefer the shape of large seals called haaf-fish.[1]
The seal bride
The typical selkie story runs like this. A man walking on the shore comes across seal people dancing or resting in human form, with their skins laid on the rocks. He steals one skin and hides it. Its owner, a young woman, cannot return to the sea without it and must go with him as his wife. She may live with him for years and bear him children, but she is always restless, gazing out at the sea. Eventually she finds the skin, often with the help of one of her children who has seen where it was hidden, and returns to the sea at once. In some versions she already had a seal husband waiting for her; in others, her children later see a large seal swimming close to shore, greeting them sadly.[1]
The folklorist Walter Traill Dennison found a version of this story on practically every island in Orkney. In one, from North Ronaldsay, a confirmed bachelor called the “goodman of Wastness” falls in love with a seal maiden; his youngest daughter has seen him hide the skin in the roof. In a version from Deerness, the wife is said to have accepted the hiding of her skin, preferring to keep her seal days out of her mind, but when she found it she left in such haste that her clothes were scattered about the house. Samuel Hibbert published a Shetland version set on Unst in 1822.[1]
Male selkies
Male selkies are described as strikingly handsome in human form, with great power to seduce human women, especially those who were unhappy or lonely, such as fishermen’s wives waiting for husbands at sea. In an Orkney rumor about a woman given the pseudonym “Ursilla,” she was said to summon her selkie lover by shedding seven tears into the sea. The ballad The Great Silkie of Sule Skerry tells of a seal man who fathers a child with a human woman, returns years later to take the child into the sea and pays her in gold as a fee.[1]
Rules, origins and taboos
- Timing. Storytellers disagreed about when selkies could become human. Some said it depended on particular tides; others said once every seven years, or, in the Faroes, once a year on the Thirteenth Night after Christmas.[1]
- Origins. Some traditions said selkies were humans condemned for wrongdoing, or fallen angels; others that they were formed from the souls of the drowned.[1]
- Killing seals. Islanders killed seals for their skins and oil only in hard times, and killing one was believed to bring bad luck. One tale recorded by Ernest Marwick tells of a crofter whose sheep all vanished on the night he killed a seal, while his neighbors’ sheep were untouched.[1][2]
Selkies around the North Atlantic
The folklorist Reidar Christiansen classified the seal bride as migratory legend type ML 4080, and scholars recognize it as a variant of the widespread “swan maiden” story, in which a man steals the feather cloak of a bird woman. Hundreds of seal bride stories have been recorded between Ireland and Iceland.[1]
- Faroe Islands. The legend of the Kópakonan, the seal woman of Mikladalur on Kalsoy, follows the classic pattern, but ends in tragedy: after her escape, her human husband kills her seal husband and two seal sons on a hunt, and she curses the island, swearing that men will be lost until there are enough to link arms around Kalsoy.[1]
- Iceland. Jón Árnason published “The Seal-Skin” (Selshamurinn), in which the wife finds the key to her chest in her husband’s clothes at Christmas. An earlier version was recorded by Jón Guðmundsson the Learned in 1641, who called the seal people marmennlar, merfolk.[1]
- Ireland. The Conneely family of Connemara were said to be descended from seals, and killing seals was taboo for them. A Kerry tradition said the Lee family of Tralee descended from a man who married a mermaid who later returned to her seal husband.[1]
- Gaelic Scotland. Gaelic stories rarely distinguish seal women from mermaids, but the MacCodrum clan of the Outer Hebrides were known as “the MacCodrums of the seals,” claiming descent from a fisherman and a seal woman.[1]
Selkies are sometimes confused with the Finfolk of Orkney, sorcerous sea people who carried off human spouses to their underwater home, and with the mermaids and mermen of wider tradition. Dennison insisted that selkies and Finfolk were distinct in Orkney, though the line was blurred in Shetland.[1][3]
Selkie children
Many stories say that children of selkie and human unions carried a physical mark. Some had webbing between their fingers and toes; in the story of “Ursilla,” it had to be clipped away periodically and grew back as a horny material. Dennison, who was related to the family concerned, said some descendants really did have the trait. In other accounts, selkie descendants had rough, cracked skin. The ethnographer David Thomson collected many such stories in The People of the Sea.[1]
Explaining the selkie legend
Since selkies are a folk tradition rather than a reported unknown animal, “explanations” here are suggestions about what shaped the stories, rather than identifications of a creature.[1]
- Seals themselves. Seals have large, dark, expressive eyes and an inquisitive habit of watching people from the water. Grey seals haul out on rocks in groups and make wailing, almost human calls. People who lived alongside them every day could easily imagine a human mind behind the eyes.
- Inherited conditions. Syndactyly, the inherited webbing of fingers or toes, runs in families. A family with webbed hands could explain the trait, and their own distinctiveness, through descent from a selkie.[1]
- Strangers in skins. The antiquarian David MacRitchie argued that the legends preserved encounters with Sámi or Finnish people, or Inuit, in sealskin kayaks and clothing. Others connected the stories with “Finn-men,” thought to be Inuit from the Davis Strait. A stranger removing a skin from a kayak or drying sealskin clothes on a rock could look like a seal turning into a man.[1]
- Social meaning. Many modern readers see the seal bride story as a tale about marriage, captivity and the longing for freedom, and about the dangers and gifts of the sea for island communities.
Selkies in modern culture
Selkies have inspired a great deal of modern writing, music and film, including George Mackay Brown’s story “Sealskin,” Mollie Hunter’s novel A Stranger Came Ashore (1975), the film The Secret of Roan Inish (1994), the Irish film Ondine (2009) and the animated film Song of the Sea (2014).[1]
Our assessment
Selkies are not a mystery animal. They are one of the richest folklore traditions of the North Atlantic, built around real seals, real island families and real stories told for centuries. The seal bride tale probably draws on many sources, including seal behavior, inherited physical traits and, possibly, distant encounters with peoples who dressed in skins and traveled in skin boats. Their enduring appeal lies in what they say about the sea, belonging and freedom.
