mermaiding

Mermaiding is a practice in which people swim while wearing a tail or monofin to resemble a mermaid. It is pursued as recreation, performance art, or cosplay, and can involve swimming in pools, lagoons, or open water, as well as underwater photography and choreography.

Equipment and technique: A typical mermaid tail has a fabric or silicone exterior with a built-in monofin that encases the legs; sometimes a separate monofin is worn with a fabric tail. Movement is generated primarily by the monofin, enabling dolphin-like propulsion. Training covers swimming efficiency, breath control, and safety drills; many mermaids train in shallow pools or supervised settings before attempting open-water or deep-water swimming.

History and culture: Mermaiding draws on mythic traditions of mermaids and the modern hobby movement; it expanded in the 2000s with tail merchandise, online tutorials, and mermaid-themed events. Communities share tips on tail construction, safety, and performances.

Safety and ethics: Mermaiding carries drowning risk and requires appropriate supervision, safe water conditions, and proper fit; never mermaid alone; use designated training spaces; ensure temperature and air safety; avoid long breath-holds; maintain gear to prevent skin irritation.
