Selkies are creatures from Scottish and Irish folklore. They are seal-like beings that have the ability to transform into human beings by shedding their skin. Selkies are said to be very beautiful and graceful, with long flowing hair and big, soulful eyes.
The legend goes that if a human finds a selkie's skin while they are in their human form, they can force the selkie to remain human and marry them. But if the selkie ever finds their skin again, they will return to their seal form and swim away, leaving their human spouse behind.
It's not clear why selkies are said to be so alluring to humans, but one theory is that they represent the wild, free spirit of the sea. They are mystical creatures that remind us of the power and beauty of nature, and perhaps that's why they continue to capture our imaginations.
