Mermaids have the upper body of a human and the tail of a fish. Mermaids are female while their male counterparts are called mermen. The general term merfolk is also used.
The term "mermaid" is often used interchangeably with "siren" in contemporary contexts; "siren" used to describe a creature with the head of a woman and body of a bird in Ancient Greek mythology but became conflated with "mermaid" during the medieval period.
The most famous mermaid is undoubtedly Disney's character Ariel from "The Little Mermaid" loosely based on Hans Christian Andersen's fairy tale of the same name.
Mermaids are sometimes conflated with sirens.
