Sympterygia is a genus of fish in the family Arhynchobatidae found in oceans off South America. [1]
There are four species in the genus: [1]
The Percopsiformes are a small order of ray-finned fishes, comprising the trout-perch and its allies. It contains just ten extant species, grouped into seven genera and three families. Five of these genera are monotypic
Pollock or pollack is the common name used for either of the two species of North Atlantic marine fish in the genus Pollachius. Pollachius pollachius is referred to as pollock in both North America and the United Kingdom, while Pollachius virens is usually known as coley in the British Isles. Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe; while P. virens is also known as Boston blue, silver bill, or saithe.
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more than 200 species in 11 genera. The perches, and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family.
The cutlassfishes are about 45 species of predatory fish in the family Trichiuridae found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth.
Lepisosteus is a genus of gars in the family Lepisosteidae.
Gouramis, or gouramies, are a group of freshwater anabantiform fishes that comprise the family Osphronemidae. The fish are native to Asia—from Pakistan and India to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae.
The beardfishes consist of a single extant genus, Polymixia, of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. Until recently they were classified in their own order Polymixiiformes. But as Nelson says, "few groups have been shifted back and forth as frequently as this one, and they were recently added to Paracanthoptergii". For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance.
The Doradidae are a family of catfishes also known as thorny catfishes, raphael catfishes or talking catfishes. These fish are native to South America, primarily the Amazon basin and the Guianas.
Mustelus also known as the smooth-hounds is a genus of sharks in the family Triakidae. The name of the genus comes from the Latin word mustela, meaning weasel. It should not be confused with the genus name Mustela, which is used for weasels.
The New Zealand smooth skate is a skate of the genus Dipturus, found around New Zealand at depths between 15 and 1,300 m.
Diplomystus is an extinct genus of freshwater clupeomorph fish distantly related to modern-day extant herrings, alewives, and sardines. The genus was first named and described by Edward Drinker Cope in 1877. There are seven species of Diplomystus: D. dentatus, D. birdii, D. dubetreiti, D. shengliensis, D. kokuraensis, D. primotinus, and D. altiformis.
Albulidae is a family of fish, commonly known as the bonefishes, that are popular as game fish in Florida, select locations in the South Pacific and the Bahamas and elsewhere. The family is small, with 11 species in 3 genera. Presently, the bonefishes are in their own order: Albuliformes. The families Halosauridae and Notacanthidae were previously classified in this order, but are now, according to FishBase, given their own order Notacanthiformes. The largest bonefish caught in the Western Hemisphere is a 16-pound, 3 ounce example caught off Islamorada, Florida, on March 19, 2007.
Agamyxis is a genus of thorny catfishes.
Cyprinella is a genus of fish in the family Cyprinidae, the carps and minnows. They are known as the satinfin shiners. They are native to North America, and some are among the most common freshwater fish species on the eastern side of the continent. Conversely, several Cyprinella species with small distributions are threatened and the Maravillas Creek subspecies of the red shiner is extinct.
Madtoms are freshwater catfishes of the genus Noturus of the family Ictaluridae. It is the most species-rich family of catfish in North America, native to the central and eastern United States, and adjacent parts of Canada. Their fin spines contain a mild venom with a sting comparable to that of a honey bee.
The bignose fanskate is a species of fish in the family Arhynchobatidae. It is found off Argentina, Brazil, and Uruguay. Its natural habitats are open seas and shallow seas.
The smallnose fanskate is a species of fish in the family Arhynchobatidae. It is found off the coasts of Argentina, Brazil, Chile, and Uruguay. Its natural habitats are open seas, shallow seas, and estuarine waters.
The filetail fanskate is a species of fish in the family Arhynchobatidae. It is endemic to the Pacific coast of Chile. Its natural habitat is open seas.
