Electric Shock (Ex): An electric eel can discharge a jolt of electricity with a 15' radius. Creatures within 5' take 3d8 points of electrical damage, those 5-10' away take 2d8 points, and those 10-15' away take 1d8 points. Opponents must also succeed at a Fortitude save (DC 11) or be stunned for 2d4+2 rounds. The eel must recharge itself for an hour between attacks.

Blindsight (Ex): Electric eels can detect objects and creatures (in the water) within 30' using their electrical sense organs. If this ability is negated by the presence of a strong magnetic field or electrical current, the eel suffers a -4 to Spot checks.

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.
