A merperson is a piscine humanoid and aquatic creature, with a human-looking upper body and a fish-like lower body. It is usually referred to with its female mermaid (less commonly mergirl) or male merman (less commonly merboy) and in plural with merfolk (less commonly merpeople). The female mermaids are regularly confused with sirens, who however are winged creatures.
