Description

The Pacific electric ray is an electric ray (Torpedinidae) from the northeastern Pacific. The species has a round, fleshy body disc and bears a pair of electric organs on either side of the head with which it can deliver a powerful jolt. It lives bottom-bound on the outer continental shelf, around rocks, in kelp beds and on sand bottoms. With a stunning shock it overpowers fishes, which it then engulfs. The shock can give a person a painful injury and danger in the water.
