Genera

Dartfishes are a group of fish, formerly considered to be a subfamily, Ptereleotrinae, of goby-like fishes in the family Microdesmidae of the order Gobiiformes, [2] Authorities now consider the species in the family Microdesmidae are within the Gobiidae, although the researchers do not define the taxonomic status of this grouping within that family. [3] They are saltwater fish.[ citation needed ]

Centrarchidae Family of fishes

Centrarchidae are a family of freshwater ray-finned fish belonging to the order Perciformes. The type genus is Centrarchus. The centrarchid family comprises 38 species of fish, 34 of which are extant and includes many fish familiar to North Americans, including the rock bass, largemouth bass, bluegill, pumpkinseed, green sunfish, and crappies. All species in the family are native to only North America.

Clupeiformes Order of fishes

Clupeiformes is the order of ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important forage and food fish.

Characiformes Order of fishes

Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.

Characidae Family of fishes

Characidae, the characids or characins is a family of freshwater subtropical and tropical fish, belonging to the order Characiformes. The name "characins" is the historical one, but scientists today tend to prefer "characids" to reflect their status as a by and large monophyletic group at family rank. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes that remain in the Characidae for the time being 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 and also include popular aquarium fish species.

Gobiidae Family of fishes

Gobiidae is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera, sometimes referred to as the "true gobies". Most of them are relatively small, typically less than 10 cm (3.9 in) in length. The Gobiidae includes some of the smallest vertebrates in the world, such as Trimmatom nanus and Pandaka pygmaea, Trimmatom nanus are under 1 cm long when fully grown, then Pandaka pygmaea standard length are 9mm (0.35 in),maximum known standard length are 11 mm (0.43 in). Some large gobies can reach over 30 cm (0.98 ft) in length, but that is exceptional. Generally, they are benthic, or bottom-dwellers. Although few are important as food for humans, they are of great significance as prey species for commercially important fish such as cod, haddock, sea bass, and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus Ptereleotris. Phylogenetic relationships of gobiids have been studied using molecular data.

Amazon basin A major drainage basin in South America drained via the Amazon River into the Atlantic Ocean

The Amazon Basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 6,300,000 km2 (2,400,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, French Guiana (France), Guyana, Peru, Suriname, and Venezuela.

Combtooth blenny Family of fishes

Combtooth blennies are blenniiformids; percomorph marine fish of the family Blenniidae, part of the order Blenniiformes. They are the largest family of blennies with around 401 known species in 58 generas. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments.

Fish Vertebrate animal that lives in water and usually has gills

Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Around 99% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with over 95% belonging to the teleost subgrouping.

Wormfishes were a subfamily, Microdesminae, which are formerly classified in the family Microdesmidae and are also currently classified, with no intervening rank, in the family Gobiidae and the order Gobiiformes.

Microdesmidae Family of fishes

The Microdesmidae, the wormfishes and dartfishes, were a family of goby-like fishes in the order Gobiiformes, more recent workers have placed this taxon within the Gobiidae, although the researchers do not define the taxonomic status of this grouping within that family. Two subfamilies in this family were briefly treated as full families - the Ptereleotrinae (dartfishes) and Microdesminae (wormfishes). The family includes about 82 species.

Gobiiformes Order of fishes

The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "Goby-like".

Springeratus caledonicus, the Caledonian weedfish, is a species of clinid found around New Caledonia and Australia. This species placement in the family Clinidae has been questioned with some feeling that it is best placed in the family Microdesmidae.

<i>Nemateleotris</i> Genus of fishes

Nemateleotris is a genus of dartfishes native to the Indian and Pacific oceans.

<i>Oxymetopon</i> Genus of fishes

Oxymetopon is a genus of fish formerly classified in the family Microdesmidae but now classified in the Gobiidae. They are native to the western Pacific Ocean. They are sometimes called ribbon-gobies.

Cichliformes Order of fishes

Cichliformes is an order of fishes. Its members were previously classified under the order Perciformes, but now many authorities consider it to be an independent order within the subseries Ovalentaria.

Labriformes Order of ray-finned fishes

Labriformes is an order of ray-finned fishes which includes the wrasse, cales and parrotfishes, within the clade Percomorpha. Some authors include the Labroformes as the clade Labroidei within the Perciformes while others include more families within the Labriformes, such as the cichlids and damselfishes, but the 5th edition of Fishes of the World includes just three listed in the section below and includes 87 genera and about 630 species.

Zagadkogobius ourlazon is a species of fish in the family Microdesmidae native to the deep-water of southwestern South China Sea. This species is the only member of its genus.

Nemateleotris exquisita is a species of dartfish which was described in 2013 from specimens collected in the Red Sea, off Mauritius and Kwa-Zulu Natal, South Africa. Formerly, the elegant firefish was thought to be found in the western Indian Ocean but N. exquisita was found to be larger, with a more slender body and longer snout, as well as the having a shorter first spine on the first dorsal fin. They also differ in colour with this species being yellow in the anterior part of the body and this colour extends further towards the tail than the analogous coloured area on N. decora. A hybrid N. decora x esquisita is thought to have been photographed in the Maldives in 1988, while the IUCN states that further taxonomic research is required to ascertain the validity of N. exquisita.

Carangiformes Order of fishes

Carangiformes is an order of the ray-finned fishes. The order is part of a clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Anabantiformes, Istiophoriformes and Pleuronectiformes. The Carangiformes has been regarded as a monotypic order, with only the Carangidae within it, by some authorities and the families within the order have been classified as part of the wider order Perciformes. The 5th edition of Fishes of the World classify six families within the order Carangiformes.

<i>Ptereleotris randalli</i> Species of fish

Ptereleotris randalli, the Brazilian dartfish, is a fish belonging to the family Gobiidae and subfamily Ptereleotrinae. Like other dartfishes, it lives over sand and rubble bottoms, and quickly retreats into holes when approached. It was originally thought to be restricted to Brazil, south to Santa Catarina, but recently reported for the southern Caribbean, where it's found at depths of 8-60m.
