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.

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.
Torpedo is a genus of rays, commonly known as electric rays, torpedo rays, or torpedoes. They are slow-moving bottom-dwellers capable of generating electricity as a defense and feeding mechanism.
During the day, the Pacific electric ray is an ambush predator: when a fish approaches its head, the ray "jumps" forward from its resting place and folds down its disc to envelop it, while delivering strong shocks. Once the fish is subdued, the ray repositions itself to swallow it head-first.
The marbled electric ray (Torpedo marmorata) is a species of electric ray in the family Torpedinidae found in the coastal waters of the eastern Atlantic Ocean from the North Sea to South Africa. This benthic fish inhabits rocky reefs , seagrass beds, and sandy and muddy flats in shallow to moderately deep waters.
The largest species is the Atlantic torpedo, Tetronarce nobiliana, which can grow to a weight of 90 kg (200 lb) and deliver a 220-volt electric shock. Electric rays have patches of modified muscle cells called electroplaques that make up an electric organ. These generate an electric gradient, similar to the normal electric potential across most ...
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.
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]
