When Duscphish beckons to other Pokémon, they seem to be compelled to follow it into the marshes it lives in. Once they step into the murky water, Duscphish tightly seizes them with a vice-like grip, then tries to drag its prey beneath the surface.

Once it grips prey with its large pincers, it will never let go, no matter what. It is thought that its body is hollow with only a spectral ball of fire burning inside.
