Electric shock (Ex): A torpedo ray has electric organs in its wings which do 2d4 electrical damage on a successful hit and force the opponent to succeed at a Fortitude save (DC 11) or be stunned for 1d4+1 rounds. The ray must recharge itself for 1 minute between attacks.

Aquatic Subtype

Creatures with the aquatic subtype always have swim speeds and thus can move in water without making Swim checks. An aquatic creature can breathe underwater. It cannot also breathe air unless it has the amphibious special quality.
