Selkies are mythical creatures from Scottish and Irish folklore, often depicted as seals that can shed their skin to become human. According to legend, they live in the sea but can come ashore to interact with humans. The transformation is central to many stories, where the selkie's skin is hidden or stolen, leading to various adventures and romances. In these tales, selkies are typically portrayed as gentle and melancholic beings, longing for their ocean home. Their stories often explore themes of love, loss, and the connection between humans and nature, making them a fascinating part of Celtic mythology.
