Tetronarce tremens, commonly known as the Chilean torpedo, is a species of fish in the family Torpedinidae. It is found in Chile, Colombia, Costa Rica, Ecuador, and Peru. Its natural habitat is open seas. [2]
The electric rays are a group of rays, flattened cartilaginous fish with enlarged pectoral fins, composing the order Torpediniformes. 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. There are 69 species in four families.
The family Torpedinidae contains 22 species of electric rays or torpedoes, flat cartilaginous fishes that produce electricity as a defense and feeding mechanism. They are slow-moving bottom-dwellers.
The redspotted catshark, also known as the Chilean catshark, is a species of catshark commonly found in the coastal waters of the southeastern Pacific, from central Peru to southern Chile. They are typically found in the rocky sublittoral areas at the edge of the continental shelf, in waters down to 100 m in depth. They spend the spring, summer, and fall in rocky subtidal areas, but winter in deeper offshore waters due to the strong currents at that time of year.
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.
Naso vlamingii, the bignose unicornfish, scibbled unicornfish, Vlaming's unicornfish, and zebra unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This species is found in the Indo-Pacific.
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 black-spotted torpedo is a poorly known, uncommon species of electric ray in the family Torpedinidae, known for being capable of generating an electric shock. It is endemic to southern Africa and possibly several small Indian Ocean islands, although the latter reports may represent undescribed new species. Its appearance is similar to the Gulf torpedo, but it is duller in coloration.
Torpedo panthera also known as the leopard torpedo is a species of fish in the family Torpedinidae. It is found in Djibouti, Egypt, Eritrea, India, Iran, Oman, Pakistan, Saudi Arabia, Somalia, Sudan, and Yemen. Its natural habitat is open seas.
Tetronarce puelcha, commonly known as the Argentine torpedo, is a species of fish in the family Torpedinidae. It is found in Argentina, Brazil, and Uruguay. Its natural habitat is open seas. It is rare electric ray fish species, which is moderately large (104 cm) found in South West Atlantic.
The Gulf torpedo 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. It is distinguishable from other Torpedo species in its range by its ornate dorsal coloration. Another common name, marbled electric ray, is not to be confused with Torpedo marmorata.
Champsocephalus esox, the pike icefish or northern icefish, is a species of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes.
The Atlantic torpedo 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. Younger individuals generally inhabit shallower, sandy or muddy habitats, whereas adults are more pelagic in nature and frequent open water. Up to 1.8 m (6 ft) long and weighing 90 kg (200 lb), 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, and two dorsal fins of unequal size.
Cancelloxus elongatus, the whiteblotched klipfish, is a species of clinid found in subtropical waters of the Atlantic Ocean along the South African coast. It prefers sandy habitats with nearby rocks at depths of from 10 to 25 metres. It can reach a maximum length of 5 centimetres (2.0 in) TL. This species preys primarily on zoobenthos.
Clinus berrisfordi, the Onrust klipfish, is a species of clinid that occurs in subtropical waters of the Atlantic Ocean from False Bay to Skoenmakerskop, South Africa where it prefers marine and brackish habitats with plentiful growth of seaweed. This species can reach a maximum length of 12 centimetres (4.7 in) TL.
The Japanese sleeper ray is a species of electric ray in the family Narkidae. It is common in the inshore and offshore waters of the northwestern Pacific Ocean from southern Japan to southern China. Growing up to 40 cm (16 in) long, the Japanese sleeper ray has a nearly circular pectoral fin disc colored reddish to chocolate brown above, sometimes with darker or lighter spots, and lighter brown below. The spiracles behind its small eyes have raised, smooth rims. Its short and muscular tail bears a single dorsal fin positioned aft of the rounded pelvic fins, and terminates in a large caudal fin.
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 than Torpedo species, which are usually small to moderate sized electric rays.
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.
The west coast seabream or west coast steenbras is a species of marine fish in the family Sparidae. It is found in very shallow water off the coasts of to Angola, Namibia and South Africa. The International Union for Conservation of Nature lists its conservation status as being "near threatened".
The sand steenbras or striped seabream is a species of marine fish in the family Sparidae. It is found in shallow water in the Mediterranean Sea and in the eastern Atlantic Ocean from France to South Africa. It also occurs in the Red Sea and off the coast of Mozambique in the Indian Ocean. The IUCN has assessed its conservation status as being of "least concern".
Cirripectes heemstraorum, the yellowtail blenny, is a species of combtooth blenny from the family Blenniidae. It is found in the Indian Ocean where it is known from three South African specimens and an Indonesian specimen. It is distinguished from its congeners by the nape having an extensive black flap on both sides of its neck; 10-13 cirri which are found between the neck flaps; an entire dorsal fin; 5-6 cirri above the eye, 6-8 cirri on the nose; the males have small dark spots on their body towards the tail which merge to form short black stripes on caudal peduncle, in life the females have a brilliant yellow caudal fin while in the males only the outer half of the tail is bright yellow.
