Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm (0.5 in) in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
Sciaenidae is a family of ray-finned fishes belonging to the order Acanthuriformes. They are commonly called drums or croakers in reference to the repetitive throbbing or drumming sounds they make. The family consists of about 293 to 298 species in about 66 or 67 genera.
Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia, but are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
Cobitidae, also known as the true loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
The tench or doctor fish is a fresh- and brackish-water fish of the order Cypriniformes found throughout Eurasia from Western Europe including the British Isles east into Asia as far as the Ob and Yenisei Rivers. It is also found in Lake Baikal. It normally inhabits slow-moving freshwater habitats, particularly lakes and lowland rivers.
Synanceiinae is a subfamily of venomous ray-finned fishes, waspfishes, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives. These fishes are found in the Indo-Pacific oceans. They are primarily marine, though some species are known to live in fresh or brackish waters. The various species of this family are known informally as stonefish, stinger, stingfish and ghouls. Its species are known to have the most potent neurotoxins of all the fish venoms, secreted from glands at the base of their needle-like dorsal fin spines. The vernacular name, stonefish, for some of these fishes derives from their behaviour of camouflaging as rocks. The type species of the family is the reef stonefish.
The superorder Elopomorpha contains a variety of types of fishes that range from typical silvery-colored species, such as the tarpons and ladyfishes of the Elopiformes and the bonefishes of the Albuliformes, to the long and slender, smooth-bodied eels of the Anguilliformes. The one characteristic uniting this group of fishes is they all have leptocephalus larvae, which are unique to the Elopomorpha. No other fishes have this type of larvae.
Trichodontidae, the sandfishes, is a small family of ray-finned fishes from the order Perciformes. The species in this family are found in the North Pacific Ocean.
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 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Tincinae is a doubtful subfamily of freshwater ray-finned fish from the family Cyprinidae, it consists of the tench of Eurasia and the east Asian clod minnows.
Psilorhynchus is a genus of ray-finned fish in the family Psilorhynchidae native to South Asia. This genus is the only member of its family. The members of Psilorhynchus are small benthic fishes which occur in rivers and streams with fast to swift currents, hence they are often referred to as torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats.
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows.
Loaches are ray-finned fish of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genera divided among 9 families.
Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of Fishes of the World, is placed within the order Scorpaeniformes, alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes.
Congroidei is a suborder of ray-finned fishes belonging to the order Anguilliformes, the eels. These eels are mostly marine, although a few species of snake eel will enter freshwater, and they are found in tropical and tempareate waters throughout the world.
Squaliobarbinae is a small subfamily of the carp and minnow family, Cyprinidae, which consists of three monotypic genera which have their natural distributions in eastern Asia. Two species, the grass carp and the black carp, have been introduced to other parts of the world for weed control and aquaculture. They are large cyprinids characterised by an enlarged subtemporal fossa, the palate articulating with the supraethmoid, an enlarged intercalar bone in the cranial vault, and a divided levator posterior muscle.
Xenocyprinae, is a contentious subfamily of the family Cyprinidae, the carp and minnow family, originally from eastern Asia.
Acanthuriformes is an order of ray-finned fishes, part of the Percomorpha clade. Some authorities place the fishes in the order within the Acanthuriformes in the suborders Acanthuroidea and Percoidea of the order Perciformes.
Clupeoidei is a suborder of marine and freshwater ray-finned fishes belonging to the order Clupeiformes, an order which includes the herrings, anchovies and shads.
Scorpaenini is a tribe of marine ray-finned fishes, one of two tribes in the subfamily Scorpaeninae. This tribe contains the "typical" or "true" scorpionfishes. The taxonomy of the scorpionfishes is in some flux, the 5th Edition of Fishes of the World treats this taxa as a tribe within the subfamily Scorpaeninae of the family Scorpaenidae within the order Scorpaeniformes, while other authorities treat it as a subfamily within a reduced family Scorpaenidae within the suborder Scorpaenoidei, or the superfamily Scorpaenoidea within the order Perciformes.
