The Legend of the Selkie

I've been researching selkies lately, and this is what I've found:

Selkies are able to become human by taking off their seal skins, and can return to seal form by putting it back on. Stories concerning selkies are generally romantic tragedies. Sometimes the human will not know that their lover is a selkie, and wakes to find them gone. Other times the human will hide the selkie's skin, thus preventing them from returning to seal form. Male selkies are very handsome in their human form, and have great seduction powers over human women. They typically seek those who are dissatisfied with their romantic life. This includes married women waiting for their fishermen husbands. If a woman wishes to make contact with a selkie male, she has to go to a beach and shed seven tears into the sea.

If a man steals a female selkie's skin, she is in his power, to an extent, and she is forced to become his wife Female selkies are said to make excellent wives, but because their true home is the sea, they will often be seen gazing longingly at the ocean. If she finds her skin again, she will immediately return to her true home, and sometimes to her selkie husband, in the sea.

Sometimes, a selkie maiden is taken as a wife by a human man and she has several children by him. In these stories, it is one of her children who discovers her sealskin (often unwitting of its significance) and she soon returns to the sea. The selkie woman usually avoids seeing her human husband again but is sometimes shown visiting her children and playing with them in the waves.
