A piscapallion is a mythical creature that resembles a fish with the ability to take on human form. Often depicted in folklore and fantasy literature, it embodies themes of transformation and duality, bridging the gap between aquatic and terrestrial life. The term combines "pisca," relating to fish, and "pallion," which suggests a cloak or covering, symbolizing its nature of hiding its true form. While not widely recognized in mainstream mythology, it serves as a fascinating element in creative storytelling.
