[[caption-width-right:350:How'd he wind up with a [[{{Kitsune}} fox]] like her?\\
It's ... complicated.]]

A [[OralTradition folklore]] trope which appears throughout the world a lot. The story typically goes something like this:

''"A man spies a group of [[VoluntaryShapeshifting magical shapeshifters]] bathing. Seeing that they must shed their creature skin when they [[HumanityEnsues transform from a creature into a beautiful woman]], he steals one of the skins. [[ShapeshifterModeLock Unable to transform]] and join her sisters, one poor creature is left behind. The man makes the abandoned one his wife. One day, many years later (sometimes after bearing children), she finds the skin and may finally return to her kin."''

It's a motif, sometimes known as "The Animal Bride" tale, that crops up all over the world. Though the details of the story are different, the core story is more or less the same.

A popular variation has a creature fall in love with a human and ''willingly'' take on human form to marry him. But when he finds out about it, often by [[ForbiddenFruit breaking a promise]], she must leave him. A lesser but still plentiful one is where he gives back the skin, and she is grateful -- which is good, because there is an invariably a villain whose tasks for him are impossible without her advice.

Occasionally, this is used as an introduction to the FairyTale type, TheQuest For the Lost Wife. It is common enough to be its own subtype, The Swan Maiden.

A GenderFlip version of this FairyTale has the heroine wooed by an animal; once she consents to marry him, he turns into a man at night. But when she violates a prohibition -- frequently burning his animal skin or actually seeing him in human form -- he must leave her. This results in the FairyTale type known as the Search for the Lost Husband. Unlike the female version, the male's InvoluntaryShapeshifting is usually the result of a {{Curse}}.

The WonderChild may be animal in form, but the wedding usually inaugurates a period where he can switch back and forth, or completely breaks the form.

!!Examples

[[foldercontrol]]

[[folder:Anime and Manga]]
* Considering that ''Anime/PrincessTutu'' is influenced quite a bit by the ballet version of SwanLake, it's probably no surprise that the anime indirectly references this legend, as well. Tutu sometimes appears as a swan to people, and was in love with the Prince from her fairytale--but ''she's'' the one who has to hide something, instead of the Prince.
* ''TearsToTiara'' uses a variation on the selkies, Llyr is a 'sea elf' who uses a seal pelt to transform into a seal. When Awarn accidentally burns it, she announces she is his wife (sea elves give their husbands their pelt, or must marry anyone who steals it).
* The most famous modern take on this is probably ''AyashiNoCeres'', wherein the spirit of a Tennyo awakens in some of her female descendants to wreak havoc on the rest of her family [[DangerousSixteenthBirthday when the descendant reaches 16]].
* Setsuna of ''MahouSenseiNegima'' is, in fact, a HalfHumanHybrid of the Tengu variety; after revealing her tengu traits she tries to skip out (per 'law of her people' and probably personal insecurities) on the crew. Negi convinces her to stick around.
* Every member of Tsukune's UnwantedHarem in ''RosarioToVampire'' is merely disguised in human form, the exception being [[CuteWitch Yukari]], whose species looks human by default. Their true forms are all [[CuteMonsterGirl cute monster girls]].
* Crane Wife is parodied in ''[[JungleWaItsumoHaleNochiGuu Hare + Guu]]'', where Guu offers Hare shaved ice in the middle of a snowstorm, he gets pissed off. She goes into the back room, telling Hare that he mustn't look at what she's going to make. He sees a silhouette of a crane through the window on the door, bursts in and sees... Guu making more shaved ice.
* ''Anime/{{Pokemon}}'':
** An episode has the ghost of a beautiful woman seducing James and Brock. This gets awkward when the ghost turns out to be a Gastly. Not as awkward as you'd think -- it turns out in the end that the Gastly's in it to propagate the REAL ghost's legend, and to make a little money on the side (it even materializes a cash register as it's talking to said real ghost; how does it make money, you ask? It disguises itself as a crazy old lady and sells fake wards and charms). The Gastly in question is MALE.
** In the episode, "Just Waiting on a Friend", a Ninetales takes the form of a woman to lure Brock to her mansion because of mistaken identify. She had thought that Brock was her long-lost master. Given that the Ninetales 'are'' Kitsunes, it's surprising how long it took them to reference this trope.
* Hana's boyfriend in ''Anime/WolfChildrenAmeAndYuki'' reveals himself to be a wolf-man after they'd been going out for some time. [[spoiler: His role is tragically cut short when he drowns in a storm drain while hunting.]]
[[/folder]]

[[folder:Comicbooks]]
* An issue of ''NinjaHighSchool'' features this almost exactly; Jeremy, visiting his grandfather in Japan, aids an injured crane, and a girl shows up to reside with them. Of course, she pays them back by working as a software programmer. In crane form.
* ''TheGoodNeighbors'' has two swan maidens - well, one maiden and her brother - among the many, many fae in the college town at the center of the book. The whole folk tale is rather deconstructed, as [[spoiler: when their skins are taken by a mortal, the girl is effectively forced into sexual slavery, and it's up to her brother to kill her and end her torment, as he can't act against her captor either.]]
* In ''Comicbook/TheSandman'' novella ''Dream Hunters'', a fox falls in love with a monk. Their love is doomed, though not for the usual reasons this sort of affair doesn't work out.
[[/folder]]

[[folder:Fan Fiction]]
* In the {{Brave}} / {{HowToTrainYourDragon}} crossover [[http://www.fanfiction.net/s/8275728/1/The-Lady-of-the-Loch The Lady of The Loch]] [[spoiler: Elinor is a selkie that was saved from the dragon Mor'du by Fergus, with whom she stayed with out of love and gratitude. Neither Fergus or her children are aware of this, which causes problems when the witch asks Merida to give her her mother's seal skin...]]
[[/folder]]

[[folder:Film]]
* "Lover's Vow", one of the stories in ''Film/TalesFromTheDarksideTheMovie'', referenced this folklore trope. A gargoyle came to life and rescued a man from muggers, exacting a promise never to tell anyone what had happened. Later, the gargoyle appeared to him as a beautiful woman, whom he married and had two children with. When he broke the promise to ''her'' (he didn't know who she was), she ''and both the children'' transformed back into gargoyles in a [[TransformationTrauma very horrific process]] and killed him.
** Although there is no shapeshifting involved, this is probably taken from the tale of the yuki-onna, where she first makes the man promise that he will never tell anyone of their meeting, and later marries him without his recognising her. The gruesome ending doesn't occur, though.
* The 1964 Japanese ghost story anthology ''Film/{{Kwaidan}}'' tells the yuki-onna story.
* ''GreenSnake'', based on a Chinese folk tale, involves a serpent-spirit who seduces a young man by posing as a beautiful maiden.
[[/folder]]

[[folder:Folklore and Mythology]]
* The [[http://en.wikipedia.org/wiki/Amazon_River_Dolphin Pink Dolphin]] of the Amazon is thought to take human form at night, whereupon it seduces young, impressionable girls with its charm and impregnates them, returning to the river by the morning. Typically, when a girl in that region turns up pregnant and the father is unknown, fatherhood is attributed to the dolphin. A striking feature is that its blowhole remains even when the dolphin is in human form, which demands that it use a hat to conceal it when on land. Another identifying feature is that the dolphin people wear white while on land, and the dolphin-fathered children tend have dolphin-colored skin.
* There is an Inuit legend about a petrel who is in love with a beautiful maiden, and transforms himself into a man so that he may marry her; however, his eyes are still those of a petrel and so he wears snow goggles to hide them. When the maiden takes them off, she sees his eyes and the spell is broken.
* Swan Maidens - Common to mainland Europe, and Russia. The women (occasionally men too) in question are normally swans, but they leave their feathered cloaks behind when they bathe as humans. This has influenced many stories, modern and old including the ballet ''Theatre/SwanLake'', Swanmays in ''Literature/ThreeHeartsAndThreeLions'' and ''TabletopGame/DungeonsAndDragons'', AnitaBlake's Swan Men, etc.
** {{Fairy Tale}}s incorporating this in the Quest for the Lost Wife include [[http://www.surlalunefairytales.com/swanmaiden/index.html "The Swan Maiden"]] and [[http://www.pitt.edu/~dash/swan.html#meier "The Three Swans"]].
** Fairy tales that end with the wife's escape include [[http://www.surlalunefairytales.com/swanmaiden/stories/sweden.html "The Swan Maiden"]].
* {{Selkies}} - [[CelticMythology Celtic]] and Nordic legendary seal people. If a man captures a female Selkie's skin, she is in his power and must be his wife, but she will return to the sea as soon as she finds her seal skin. In some versions of the story, the children follow their mother and transform into seals, or alternatively, drown. In others, most famously the film "[[http://madnessmonster.wordpress.com/2010/03/17/jaaaaaaaamie-review/ The Secret of the Roan Inish]]", the children cannot change as they are ([[HalfHumanHybrid mostly]]) normal humans and are left behind (and confused unless their father explains what happened). The male Selkies are seducers of women. There is a similar American Indian story of a seal boy. This again crops up often in modern fiction and other works, and has also inspired a ''Dungeons and Dragons'' race.
* Melusine - There are ''many'' versions of this romantic French tale. In one version, Melusine fell in love with a human and appeared to him as a beautiful woman. When they were married, she made her husband promise that she would have some time to herself each week. Wouldn't you know it, one day he breaks his promise and sees that she is actually [[OurdragonsAreDifferent a dragon]] (depending on other variants, she's even half-snake). Melusine is forced to go back to her family, but her children stay with the humans and a group of French nobility claimed to be her descendants for many years.
* The hero of "Literature/EastOfTheSunAndWestOfTheMoon" is a bear and once he wins the heroine, he can only take on his human form at night. Similarly with [[http://www.surlalunefairytales.com/eastsunwestmoon/stories/norroway.html "The Black Bull of Norroway"]], [[http://www.surlalunefairytales.com/eastsunwestmoon/stories/brownbear.html "The Brown Bear of Norway"]], [[http://www.surlalunefairytales.com/eastsunwestmoon/stories/enchpig.html "The Enchanted Pig"]], the dog in [[http://www.surlalunefairytales.com/eastsunwestmoon/stories/daughterskies.html "The Daughter of the Skies"]], and [[http://www.surlalunefairytales.com/eastsunwestmoon/stories/whitewolf.html "The White Wolf"]]. When the heroine [[ForbiddenFruit violates a prohibition]], he must leave her. However, when she [[TheQuest finds him]] after a long search, she is able to recover him.
** "Hans My Hedgehog" is yet another variant. It is probably best known for being dramatized in an episode of the cult favorite JimHenson series, ''Series/TheStoryteller''.
* In [[http://www.surlalunefairytales.com/pentamerone/2myrtle1911.html "The Myrtle"]], a woman wishes for a child, even a sprig of myrtle, and gives birth to one. A prince is so enthralled by it that he buys it from her, and the myrtle changes to a Fairy in his rooms at night.
* In [[http://www.surlalunefairytales.com/books/slavonic/wratislaw/shewolf.html "The She-Wolf"]], the bride was a wolf, with a wolfskin, before the miller's son nailed it down so it would not fly back to her; then, later, her son tells her where to find it.
* In the variants of the ChivalricRomance ''The Swan Children'', the bride is more or less clearly a swan-maiden; she gives birth to children who are first [[MosesInTheBullrushes exposed]] and then [[InvoluntaryShapeshifting transformed into swans]] by removing the chains they wear about their necks. When this is discovered, the children are changed back by restoring --except that one chain was melted down, trapping that child in swan form.
* Tennyo (Heavenly Maidens) - Japanese imports of Indian and Chinese Buddhist figures. The males are called Tennin. They don't change from animals but they do need a feathered garment (a hagoromo) to fly back to the heavens. The Noh play ''Hagoromo'' features the core story where the the garment in question is stolen.
* {{Kitsune}} (fox-spirits) and Tanuki (raccoon dog spirits) - Japanese trickster animal spirits. They don't leave skins behind, but they sometimes transform into beautiful women and marry men. They must leave if the man discovers their identity. Sometimes they are malicious and sometimes they are kindly. They are also sometimes female as humans, but male in their true animal forms. Among the best-known traits of the Tanuki are its ''ridiculously large testicles''.. On occasion it's implied that ''both sexes'' have the testicles, which, as far as fantastical creatures go, makes a certain amount of sense (dwarf beards, anyone?), but considering the tanuki is also a real animal is just plain weird. The strong vulpine predisposition to womanhood is also by no means binding; they are known often to have impersonated men, although a lower percentage of these are for romantic purposes.
* One particularly famous positively-depicted Fox Wife is Kuzunoha, mother of the Japanese Merlin. (A guy with the bonus cred of [[http://en.wikipedia.org/wiki/Abe_no_Seimei actually having existed.]])
* Gumiho are the Korean version of the [[FantasticFoxes nine-tailed fox]]. They occasionally seduce men, though normally they're trying to win his heart (or liver) in a [[ToServeMan more literal sense]].
* Toyotama-hime (also known as Oto-hime) - Her story is remarkably similar to that of Melusine's. Once again, she was a dragoness, specifically, the daughter of Ryujin, the Dragon King of Japan, and fell in love with the fisherman Urashima Taro. And as always, it didn't end well for them. Note that she ''has'' had at least one (slightly more) successful relationship, albeit with the god Hoori.
* The Crane Wife. A poor man finds an injured crane, and nurses it back to health. It flies away, and soon a beautiful woman shows up and marries him. She helps make him wealthy with her weaving, with the condition that he never watch her weave. He gets greedy and breaks this rule, and sees her in Crane form weaving her feathers into the silk. She then leaves once her identity is discovered.
* A Japanese story featuring a yuki-onna followed Melusine's path in a way. A man got lost in a blizzard and this snow woman showed him the way out: she made him promise never to speak of the encounter to anyone or she would kill him. Later this man meets a beautiful woman and marries her. Many years, and a son, follow and one night, after a bit of sake, the man tells his wife of the yuki-onna. The wife stands up and reveals herself to be the yuki-onna, immensely annoyed, and leaves but does not kill him. It varies on whether her reason for sparing his life was that she had given him a son and hence had some sort of emotional attachment or that since he hadn't technically told anyone ''else''.
* Second husband of Inuit sea godness, Sedna turned out to be a petrel-spirit in disguise. In some myths it’s the reason she left him later. Other Inuit legends claim that in the TheTimeOfMyths it was normal for spirits to cross border between human and animal world and vice versa. Many of them are love stories.
* In the Indian tale of Urvashi and Pururavas, Urvashi, unusually, had voluntarily chosen to marry him, and his violation of a taboo, tricked by her fellow nymphs who wanted her back, not the recovery of an item, made her leave him. However, when he is searching for her, she and the others take the form of swans.
[[/folder]]

[[folder:Literature]]
* The ''Literature/ArabianNights'' features the story of Janshah's pursuit of Shamsah. She was a Djinn who also turned into a swan by using a feathered cloak. She managed to ferret out that her swan-cloak was buried under her (new) palace the minute her fiance buried it.
** A somewhat modified version of this story appears in Lotte Reineger's ''TheAdventuresOfPrinceAchmed''. Peri Banu, a Fairy woman who uses a feathered gown to fly around as a bird, isn't too upset when the prince proposes to her, though.
* The book ''The Sterkarm Handshake'' features no actual swan-mays, but the ShapeshiftingLover legend does feature heavily in the story. The main female character, Andrea, is part of a group of [[TimeTravel time travellers]] from TwentyMinutesIntoTheFuture who travel to medieval times. When in the past, the time travellers say that they are elves. Andrea falls in love with a man from the past, but he is wary of entering into a relationship with her because swan-mays, as he thinks Andrea is, always leave their human lovers eventually. (Guess what happens at the end.)
* Megan Whalen Turner referenced the Selkie legend in one of the short stories in her book "Instead Of Three Wishes". In the story, a Selkie who has been searching for her coat for many years enlists a young girl to help her find it, after the man who tried to force her to marry him hid her coat in a painting.
* In the dark fantasy novel, ''The Folk Keeper'', the heroine has an unusual affinity for the [[TheFairFolk mysterious creatures]] of the title. [[spoiler:Turns out she's a half-Selkie. She tries to escape in her seal-form by wearing her magical skin, but it had been too damaged by the villain, making it impossible to ever remove it. Not wanting to give up her human form permanently, she rips off the skin before it's too late and loses it in a storm. She may be [[BittersweetEnding separated from her family]], but can still have a connection to the sea without the skin, and at least this way she can stay with the nice human guy who loves her.]]
* ''Selkie Girl'' by Laurie Brooks is a retelling of this story. The main character Elin Jean has had webbed fingers her whole life. She finds out that her mom [[spoiler:is a selkie. Elin then becomes a selkie as well.]]
* In the ''{{Belgariad}}'' and prequels, Poledra is a variation, since she genuinely decided to be Belgarath's wife. She is capable of switching between forms at will and is evidently as immortal as Belgarath.
* The novel ''The Woman Who Loved Reindeer'' is a rare gender-flipped version of the story. It is pretty much ExactlyWhatItSaysOnTheTin. The woman of the title falls for a legendary being known as a "[[OurWerewolvesAreDifferent Trangle]]", essentially a reindeer that occasionally looks like a man and transforms by removing his deer skin. There is an interesting complication in the relationship in that the Trangle is [[HughMann extremely aloof and uncomfortable around humans]], and it is implied near the end that he will show his lover how to transform into a reindeer herself so that their relationship can actually get anywhere.
* Elizabeth Marshall Thomas' palaeolithic romance ''The Animal Wife'' is a realistic and anthropologically rationalised story about an incident the like of which might have given rise to the widespread "animal wife" folk-tale motif. Not that anyone in the story thinks the "wife" is a shape-changer, but you can see where the story would go once it was retold a few times.
* Creator/PeterSBeagle has a short story called "The Tale Of Junko And Sayuri", where a hunter wounds an otter and takes it home with him to nurse it back to health. Once the otter is healed, it transforms into a woman and becomes his wife, who uses her power to help him move up in life, all the time not knowing what exactly she is. [[spoiler:It turns out she's an ''[[{{Youkai}} ushi-oni]]''.]]
* In the Old Norse ''Literature/SagaOfHrolfKraki'', the prince Bjorn is cursed by his WickedStepmother to transform into a bear. However, each night he turns back into a man and returns to his lover Bera.
* In ''TheHouseOfNight'' series, Rephaim, a [[CreepyCrows Raven-Mocker]], is given the gift of humanity by Nyx. However, he can only be a human at night and is forced to turn back into a Raven-Mocker during the day. This causes problems in his relationship with Stevie Rae.
* In PatriciaAMcKillip's ''Solstice Wood'', Owen recounts the story he had been told of a man who shot [[TheMarvelousDeer a deer]] without killing it and went to track it down, and found instead a woman with a bullet wound in her shoulder. She lived with him for a year and half and had a son before she vanished. [[spoiler:Then he explains that he finally realized it was his parents.]]
* The short story ''[[http://www.apex-magazine.com/jackalope-wives/ Jackalope Wives]]''. Human boy sees animals-turned-human-women dancing, decides he wants one for himself, and sets about stealing her pelt. It does not go well ''at all''. [[spoiler: His grandmother was a Jackalope once too. When her husband died and she found her pelt again, she chose to burn it so she wouldn't have to leave her children behind -- and besides, her second husband was nice.]]
* ''Literature/ABouquet of Czech Folktales'' prefers shapeshipting with plants:
** The ballad "Willow" is about a woman who shares her life with a willow. She's a woman during days, but she's lying as if she were dead at nights. When her husband finds out that she actually lives as a willow, he decides to cut the tree down because he wants to have her ''fully''. It ends badly because she dies the instant he cuts the willow and he and his little son lose her forever. Only, he's advised to make a cradle for the baby out of the wood.
** "Lily" starts with a young virgin who dies and is buried in the wood. After some time, a lily grows on the grave and the lady lives as a woman at nights, but she's a lily during days. A prince meets her, falls in love and decides to marry her.

[[folder:Music]]
* Heather Dale has a song about a woman/selkie pair where the woman finds an old selkie coat and turns into one herself.
* The Crane Wife is referenced in The Decemberists' album of the same name, which has a song explaining the story.
** They seem to like this trope. In their album ''The Hazards of Love'', the main singer is able to change into a fawn, and takes advantage of this power to, er, [[RapeIsLove "initiate" his relationship with the innocent Margaret.]] Being a human adopted by the Queen of the Forest has its perks.

* The Swanmays of ''DungeonsAndDragons'' are a secretive all-female order of humanoid rangers and druids who can turn into swans.
* Selkies are aquatic fey in ''DungeonsAndDragons'' and often travel among surface races for a time, sometimes dallying with the surfacers, but almost all eventually return to the sea.
* Silver Dragons from ''DungeonsAndDragons'', being one of the few dragons to both have the shapeshift ability and enjoy cohabitation with humanoid races, are sometimes known to do this multiple times across their very long lifespan.
* Selkies are also one of the kiths in ''ChangelingTheDreaming''. Their sealskin coat can take the form of any garment from a peacoat to a belt, and they wither and die (well, they forget all about fae existence until the next incarnation) if they spend too long away from the coast.

[[folder:Videogames]]
* The basis of Iroha's BackStory in ''SamuraiShodown Tenka''. During one of her super moves, during which she disrobes and attacks the opponent behind a screen, her silhouette briefly flickers into that of a crane's.
* History books in ''VideoGame/PokemonDiamondAndPearl'' reveal that the people in the world of Pokémon have these myths about Pokémon. {{Squick}}y - but hey, if [[HotSkittyOnWailordAction Skitty and Wailord]] can get it on, why not people, too?
* Subverted in ''DaCapo'' with Yoriko. She's a girl with cat ears, and is indeed a cat that transformed into a girl. [[spoiler:However, she transformed into the form of her owner, and her owner was piloting the body. At the end when the tree dies, the girl's real body wakes up and transfers into his school, at which point they enter a real relationship.]]

* The selkie legend appears in ''HannaIsNotABoysName'', with a little bit of deconstruction: Mrs. Hatch is a selkie, and since Mr. Hatch stole her skin, she's been stuck as his human wife for nearly two decades. She hates her husband and her son, and looking for the skin got another character killed.
* In ''WoodenRose'', [[http://www.woodenrosecomic.com/comic/chapter5/122.html Aidan Thorne is continually having to hide from Nessa that he's started to turn into a tree while he's wooing her.]]
[[/folder]]

[[folder:Western Animation]]
* The Pink Dolphin legend shows up in ''TheWildThornberrys'', but with a girl who Eliza believes to be a shape shifting River Dolphin who wants to transform Debbie into a River Dolphin because she wants a friend and is lonely. Debbie doesn't transform but it is never confirmed whether the girl in question was a Dolphin or not. Knowing about the above story [[LesYay gives the episode a distinctive lesbian subtext]].
* In the ''WesternAnimation/{{Gargoyles}}'' episode "Mark of the Panther", Eliza's mother tells the story of Anansi and a panther. Anansi turned the panther into a human woman and threatened to leave her trapped in that form forever unless she built him a city and provided him food. The panther turned woman marries a wealthy man and together they build a city and raise a family. Anansi undoes his curse, but sets up the panther to be hunted and killed by her human son since he's unhappy about losing her offerings. At the last second the son recognizes his mother and he turns into a panther to be with her. Since this is ''[[AllMythsAreTrue Gargoyles]]'', the story has a lot more truth than Eliza's mother realizes.
