Bass is a generic common name shared by many species of ray-finned fish from the large clade Percomorpha, mainly belonging to the orders Perciformes and Moroniformes, encompassing both freshwater and marine species. The word bass comes from Middle English bars, meaning "perch", despite that none of the commonly referred bass species belong to the perch family Percidae.
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.
Characidae, the characids or characins, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. The name "characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes remaining in the Characidae currently are the tetras, comprising the very similar genera Hemigrammus and Hyphessobrycon, as well as a few related forms, such as the cave and neon tetras. Fish of this family are important as food in several regions, and also constitute a large percentage of captive freshwater aquarium fish species.
Minnow is the common name for a number of species of small freshwater fish, belonging to several genera of the family Cyprinidae and in particular the subfamily Leuciscinae. They are also known in Ireland as pinkeens.
Carcharhiniformes, the Requiem sharks, are the largest order of sharks, with over 270 species. They include a number of common types, such as catsharks, swellsharks, and requiem sharks.
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 less familiar ones, such as the goblin shark and megamouth shark.
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.
Batrachoididae is the only family in the ray-finned fish order Batrachoidiformes. Members of this family are usually called toadfish or frogfish: both the English common name and scientific name refer to their toad-like appearance.
The cusk-eel family, Ophidiidae, is a group of marine bony fishes in the Ophidiiformes order. The scientific name is from the Greek ophis meaning "snake", and refers to their eel-like appearance. True eels diverged from other ray-finned fish during the Jurassic, while cusk-eels are part of the Percomorpha clade, along with tuna, perch, seahorses and others.
Discherodontus halei is a species of cyprinid fish from Southeast Asia. It appears to have a disjunct range; it is known from Pahang River in western Peninsular Malaysia and from the Tapi River in southern Thailand, as well as from the northern Chao Phraya River basin, Thailand. This species can reach a length of 10.5 centimetres (4.1 in) TL.
Discherodontus is a genus of small cyprinid fishes found in rivers and streams in Mainland Southeast Asia and Yunnan in China.
Lutjanidae or snappers are a family of perciform fish, mainly marine, but with some members inhabiting estuaries, feeding in fresh water. The family includes about 113 species. Some are important food fish. One of the best known is the red snapper.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Discherodontus colemani is a species of cyprinid fish. It is endemic to Thailand and restricted to the upper Chao Phraya River basin. It is an uncommon species that inhabits streams and river tributaries, occasionally the mainstreams.
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.
Discherodontus ashmeadi, commonly known as the redtail barb, is a fish native to the lower Mekong river basin in Thailand, Cambodia, Vietnam, and Laos. It inhabits both the mainstream Mekong and its tributaries, as well as lakes and reservoirs connected to rivers. It grows to 13.6 cm (5.4 in) SL. It is present in mixed fisheries but is not an important fishery species.
Discherodontus schroederi is a freshwater fish native to the Chao Phraya and Mae Klong basins in Thailand and to the Mekong basin in Laos. It inhabits submontane and hill streams and has also been found in the mainstream Mekong. Young individuals might occur in shaded, nearly stagnant side pools.
Somphong's puffer, redeye puffer or crested puffer is a small freshwater blowfish found in mainlands Southeast Asia such as Thailand, Cambodia, Vietnam. This fish has been collected in the past for the aquarium trade.
