Marin is a man who pretends to be a mermaid.
Present
When Luffy, Hatchan and Pappag are looking for Camie, since she was kidnapped, they end up in one of the many human stores of the Sabaody Archipelago. However, the only mermaid in the “assortment” is Marin.
However, this is such an obvious hoax that even the usually gullible Luffy sees through Marin’s disguise and realizes that “she” isn’t a mermaid.
