In folklore, a selkie is a creature that can transform between a seal and a human. Typically found in Celtic mythology, selkies embody themes of love, loss, and the connection to the sea. Their unique nature often involves tales of selkies who shed their skin to become human, exploring human emotions and the longing for freedom. Selkies represent the intersection of the human and animal worlds, emphasizing the fragility of identity and the bonds of attachment.
