Electric rays range in length from under 30 cm (1 foot) to about 2 m (6 feet). They are soft and smooth-skinned, with a circular or nearly circular body disk formed by the head and pectoral fins. The electric organs, composed of modified muscle tissue, are in the disk, one on each side of the head. The shock from these organs is used in defense, sensory location, and capturing prey. Electric shocks emitted reach 220 volts and are strong enough to fell a human adult. In ancient Greece and Rome, the shocks of the species Torpedo nobiliana were used as a treatment for gout, headache, and other maladies.
