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 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.
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.
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.
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.
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 Gulf torpedo (Torpedo sinuspersici) or variable electric ray, is a species of electric ray in the family Torpedinidae. It is found in the Indian Ocean, but may represent a species flock of several local endemic species. [1] It is distinguishable from other Torpedo species in its range by its ornate dorsal coloration. [2]
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.
