The creature that is part human, part fish, and often symbolizes temptation and danger is the mermaid. In folklore, mermaids are typically depicted as enchanting beings with the ability to lure sailors to their doom with their beautiful voices and mesmerizing appearances. They represent the duality of attraction and peril, found in numerous myths across cultures, such as the Sirens in Greek mythology. The mermaid embodies the tensions between human desire and the unpredictable nature of the sea.
