Within swamps and marshland, Zosire will lay, mouth agape, outside the homes of their prey. They use their ability of illusion to trick the Pokémon into believing there is food inside.

A Zosire hunts by leaving its mouth wide open in water and waiting for its prey to blunder in. To protect themselves from danger, they hide their true identities by transforming into people and Pokémon.
