Discocheilus is a genus of cyprinid fishes endemic to China. This genus contains two recognized species.
A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna. The Atlantic bluefin averages 2 m (6.6 ft), and is believed to live up to 50 years.
The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae.
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the [Labroidei]], along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relatives of cichlids are probably the convict blennies, and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000.
The Squaliformes are an order of sharks that includes about 126 species in seven families.
The Lamniformes are an order of sharks commonly known as mackerel sharks. It includes some of the most familiar species of sharks, such as the great white, as well as more unusual representatives, such as the goblin shark and megamouth shark.
Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes.
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.
Parrotfishes are a group of about 95 fish species regarded as a family (Scaridae), or a subfamily (Scarinae) of the wrasses. With about 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion.
Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbels.
Channa is a genus of predatory fish in the family Channidae, commonly known as snakehead, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many Channa species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range where they often become invasive. The large and medium-sized Channa species are among the most common staple food fish in several Asian countries and they are extensively cultured. Apart from their importance as a food fish, snakeheads are consumed in some regions as a traditional medicine for wound healing and reducing post-operative pain and discomfort, and collected for the international aquarium pet trade.
The Old World silversides are a family, Atherinidae, of fish in the order Atheriniformes. They occur worldwide in tropical and temperate waters. About two-thirds of the species are marine, and the remainder live in fresh water. The 74 species are in 13 genera. The genus Craterocephalus is the most diverse with 25 species. Four genera are monotypic.
Plectranthias is a genus of ray-finned fish in the subfamily Anthiinae, part of the family Serranidae, the groupers and sea basses. They are found in the Atlantic, Indian and Pacific Ocean.
The Distichodontidae are a family of African freshwater fishes of the order Characiformes.
Myotis vivesi, the fish-eating bat or fish-eating myotis, is a species of bat that lives around the Gulf of California, and feeds on fish and crustaceans. It is the largest species of the genus Myotis in the Americas, and has exceptionally large feet, which it uses in hunting. It was described in 1901 by Auguste Ménégaux and is the only species in the subgenus Pizonyx.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 140 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish and hypogean fish.
The Catostomidae are the suckers of the order Cypriniformes, with about 78 species in this family of freshwater fishes. The Catostomidae are almost exclusively native to North America. The only exceptions are Catostomus catostomus, found in both North America and Russia, and Myxocyprinus asiaticus found only in China. In the Ozarks they are a common food fish and a festival is held each year to celebrate them. Ictiobus cyprinellus can reach an age up to 112 years, making it the oldest known freshwater teleost.
John Ernest "Jack" Randall was an American ichthyologist and a leading authority on coral reef fishes. Randall described over 800 species and authored 11 books and over 900 scientific papers and popular articles. He spent most of his career working in Hawaii. He died in April 2020 at the age of 95.
Discocheilus multilepis is a fish species in the genus Discocheilus from China.
Discocheilus wui is a fish species in the genus Discocheilus from China.
