Mermaid

A mermaid is a mythological aquatic creature with a female human head and torso and the tail of a fish. Mermaids have a broad representation in folklore, literature, and popular culture.

Much like sirens, mermaids sometimes sing to people and gods and enchant them, distracting them from their work and causing them to walk off the deck or run their ships aground. Other stories depict them squeezing the life out of drowning men while attempting to rescue them.
