Tetronarce
''Tetronarce'' is a genus of rays, commonly known as electric rays. They are slow-moving bottom-dwellers capable of generating electricity as a defense and feeding mechanism. ''Tetronarce'' species tend to attain a much larger size (up to 180 cm TL) than ''Torpedo A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target.

Atlantic Torpedo
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 , and in the Mediterranean Sea. Younger individuals generally inhabit shallower, sandy or muddy habitats, whereas adults are more pelagic in nature and frequent open water. Up to long and weighing , the Atlantic torpedo is the largest known electric ray. Like other members of its genus, it has an almost circular pectoral fin disk with a nearly straight leading margin, and a robust tail with a large triangular caudal fin. Distinctive characteristics include its uniform dark color, smooth-rimmed spiracles (paired respiratory openings behind the eyes), and two dorsal fins of unequal size. Solitary and nocturnal, the Atlantic torpedo is capable of generating up to 220 volts of electricity to subdue its p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Electric Ray
''Tetronarce californica'' also known as the Pacific electric ray is a species of electric ray in the family Torpedinidae, endemic to the coastal waters of the northeastern Pacific Ocean from Baja California to British Columbia. It generally inhabits sandy flats, rocky reefs, and kelp forests from the surface to a depth of , but has also been known to make forays into the open ocean. Measuring up to long, this species has smooth-rimmed spiracles (paired respiratory openings behind the eyes) and a dark gray, slate, or brown dorsal coloration, sometimes with dark spots. Its body form is typical of the genus, with a rounded pectoral fin disc wider than long and a thick tail bearing two dorsal fins of unequal size and a well-developed caudal fin. Solitary and nocturnal, the Pacific electric ray can generate up to 45 volts of electricity for the purposes of subduing prey or self-defense. It feeds mainly on bony fishes, ambushing them from the substrate during the day and actively hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentine Torpedo

Tetronarce Macneilli
''Tetronarce macneilli'', commonly known as the shorttail torpedo, is a species of large electric ray. The taxonomy of the species has been long debated and has been suggested that it is synonymous with ''Torpedo fairchildi''. Distribution and Habitat This species is found off of southern Australia from Port Hedland to the Swain Reefs in tropical-cool temperate waters. It is noted for having an unusually large range for a ray species. It inhabits sloped continental shelves and slopes from to . It feeds on fishes and crustaceans. Description ''T. macneilli'' can grow up to long. It is capable of delivering an intense electric shock if handled in defense and also uses this ability to hunt prey Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not ki ....Compagno, L.J.V. & Last, P.R. (1999): ...

New Zealand Torpedo
''Tetronarce fairchildi'', commonly known as the New Zealand torpedo, is a species of electric ray of the family Torpedinidae found only around New Zealand, at depths of between 5 and 1,100 m. This species is placed in the genus ''Tetronarce''.Carvalho, M.R. de. (2015): Torpedinidae. In : Heemstra, P.C., Heemstra, E. & Ebert, D.A. (Eds.), Coastal Fishes of the Western Indian Ocean. ''Vol. 1. South African Institute for Aquatic Biodiversity, Grahamstown, South Africa. In press.'' In June 2018 the New Zealand Department of Conservation classified the ''T. fairchildi'' as "Data Deficient" under the New Zealand Threat Classification System The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand.

Theodore Nicholas Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist, and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington, DC, in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes, and mollusks most particularly, although he maintained proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, DC. Fellow members frequently mocked him for his vanity. He was president of the American Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
