The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes / t ɔːr ˈ p ɛ d ɪ n ɪ f ɔːr m iː z /. They are known for being capable of producing an electric discharge , ranging from 8 to 220 volts , depending on species, used to stun prey and for defense. [ 2 ]

The common torpedo (Torpedo torpedo), also known as ocellate torpedo or eyed electric ray, is a species of electric ray in the family Torpedinidae.It is found in the Mediterranean Sea and the eastern Atlantic Ocean from the Bay of Biscay to Angola, and is a benthic fish typically encountered over soft substrates in fairly shallow, coastal waters.
Eschmeyer's Catalog of Fishes classigies the rays as follows: [16] Order Torpediniformes. Family Platyrhinidae D. S. Jordan, 1923 (thornbacks or fanrays) Family Narkidae Fowler, 1934 (sleeper rays) Family Narcinidae, Gill, 1862 (electric rays) Family Hypnidae Gill, 1862 (coffin rays) Family Torpedinidae Henle 1834 (torpedo electric rays or ...
The Atlantic torpedo (Tetronarce nobiliana) is a species of electric ray in the family Torpedinidae.It is found in the Atlantic Ocean, from Nova Scotia to Brazil in the west and from Scotland to West Africa and off southern Africa in the east, occurring at depths of up to 800 m (2,600 ft), and in the Mediterranean Sea.
Numbfishes are slow-swimming bottom-dwellers that feed on small fishes and invertebrates off the bottom; their protrusible jaws aid in removing prey from the substrate. They can generate a moderate shock if disturbed and contact is made with the electric organs; the electrical discharges of narcinids have been measured at 8-37 volts, much less than the electric rays of the genus Torpedo.

The lesser electric ray (Narcine bancroftii), also known as the Brazilian electric ray, small electric ray, spotted torpedo ray, torpedofish or trembler, [2] is a species of numbfish in the family Narcinidae found on the western coastal fringes of the Atlantic Ocean and Caribbean Sea. [2]
The blind electric rays are small, flat cartilaginous fish with the round pectoral fin disc characteristic of electric rays, a short, fleshy tail, and one dorsal fin. The front part of their pelvic fins are modified for walking, while the back is fused to the disk. Their eyes are not visible externally and are practically useless, hence the name.
