For the fictional energy weapon, see. Equipped with electric organs, this ray is an advanced ambush predator whose mottled skin color renders it nearly invisible to unsuspecting eyes. Idea Incubator 1. No spine on tail. Froese, Rainer, and Daniel Pauly, eds. [2] In his dialogue Meno, Plato has the character Meno accuse Socrates of "stunning" people with his puzzling questions, in a manner similar to the way the torpedo fish stuns with electricity. Lurking unseen on the seafloor, it has the power to send a jolt of painful electricity rippling through your body. Disc white ventrally. The rays are capable of producing electric discharges ranging from 8 to 220 volts. The Electric Ray has diamond shaped wings. It generally inhabits sandy flats, rocky reefs, and kelp forests from the surface to a depth of 200 m (660 ft), but has also been known to make forays into the open ocean. Ray Species; Electric Rays: Lesser Electric Ray; Electric Rays: Lesser Electric Ray. The marbled electric ray was originally described as Torpedo marmorata by Risso in 1810. The rays are found in kelp forests and on sandy bottoms, sometimes partially buried in the sand. The electric currents produced by some species of fishes, such as the Numbfish and torpedo rays are generated in cells called electrocytes. The body is thick and flabby, with soft loose skin with no dermal denticles or thorns. If they are discovered, however, Rays won’t hesitate to use their venomous tai… Our editors will review what you’ve submitted and determine whether to revise the article. The electric eel has three pairs of electric organs; they constitute most of the mass of the body and about four-fifths of the total length…. Typically reach around 35 cm, but might grow over 61 cm in length. The presence of electric organs require a good conducting medium; it is thus not surprising to find such adaptations only among aqueous organisms. There are 69 species in four subfamilies.. Measuring up to 1.4 m (4.6 ft) long, this species has smooth-rimmed spiracles (paired respiratoryopenings behind the eyes) and a dark … The English language common names for this species are lesser electric ray, Brazilian electric ray, small electric ray, spotted torpedo ray, torpedofish, trembler and the electric ray. Electric rays are found at many depths, from shallow waters to as far as 3,000 feet below the surface. This is how they hunt and defend themselves against predators in the oceans that they dwell in. Their eyes are on the top of their heads, resulting in poor vision[citation needed] that must be compensated for the use of other senses, including detecting electricity. One of the newly discovered species is this electric ray, known by the Latin name Tetronarce cowleyi. Weight Atlantic torpedo ray may reach 90 kg (200 lbs.) How do electric eels shock? A ray is a fish that belongs to the same group as sharks (together they are known as elasmobranchs.) [2] There are 69 species in four families. These fish use electricity to zap predators and catch prey. One of the newly discovered species is this electric ray, known by the Latin name Tetronarce cowleyi. Electric rays have a rounded pectoral disc with two moderately large rounded-angular (not pointed or hooked) dorsal fins (reduced in some Narcinidae), and a stout muscular tail with a well-developed caudal fin. Common name: Lesser Electric Ray Species Codes for Trip Ticket Reporting: Marine Life Code: 697 - Ray, lesser electric Food and Bait Code: 184 - Rays (skates) License and Endorsements Required for Commercial Harvest: SPL - Saltwater Products License There are 71 species of Torpediniformes, in 14 genera and 5 family. Fast Facts Description No data Size Atlantic torpedo ray may be up to 1.82 m (6 ft) in length Female: In general, female rays are larger than males. The electric rays have a smooth and naked skin; the head and trunk with the pectoral fins form a circular disk, and the tail is short and stout. They can produce an electric discharge, ranging from as little as 8 volts up to 220 volts depending on species. Electric rays are usually 1 to 6 feet in diameter and have a more rounded shape than other rays. There is another species of electric ray in UK waters – the marbled electric ray. My spear would have been a fine conductor if the fish and I had connected.” Clark nearly zapped herself with an electric ray. One of the newly discovered species is this electric ray, known by the Latin name Tetronarce cowleyi. 4 Electric Ray. Unlike other rays, electric rays use their tails to swim, not their pectoral fins. When an electrocyte is stimulated, a movement of ions (electrically charged atoms) across the cell membrane results in an electric discharge. Electric shocks emitted reach 220 volts and are strong enough to fell a human adult. Like sharks, rays have skeletons made of flexible cartilage instead of bone. These rays are part of the Torpedinidae family, commonly called torpedoes — which is where we got the name for the weapon — that includes 22 species around the world. Compagno, Leonard J.V. There are 69 species in four families. When the Electric Ray moves, the storm follows at unnatural speed. It was a ray all right—an electric ray! They lie in wait for prey below the sand or other substrate, using their electricity to stun and capture it. Other common names include arraia, arraia-eléctrica, emplasto, raia treme treme, raia-eléctrica, raia-emplasto, treme-treme, tremelga (Portuguese), brasiliansk elrokke (Danish), kleine stroomrog (Dutch), kumoma-shibire-ei (Japanese), liten darrocka (Swedi… Round disc with a thick tail and well developed dorsal fins and caudal fin.
