A goby of the genus Rhinogobius

Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of Fishes of the World this suborder is elevated to an order Gobiiformes within the clade Percomorpha. [1] Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. [1] . Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny Pholidichthys leucotaenia . [2] The word goby derives from the Latin gobius meaning "gudgeon", [3] and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are called "gudgeons", especially in Australia. [4]

In biological classification, the order is

  1. a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. Other well-known ranks are life, domain, kingdom, phylum, class, family, genus, and species, with order fitting in between class and family. An immediately higher rank, superorder, may be added directly above order, while suborder would be a lower rank.
  2. a taxonomic unit, a taxon, in that rank. In that case the plural is orders.
Perciformes order of fishes

Perciformes, also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". This group comprises over 10,000 species found in almost all aquatic ecosystems.

<i>Fishes of the World</i> book

Fishes of the World by Joseph S. Nelson is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.

Ophidiiformes is an order of ray-finned fish that includes the cusk-eels, pearlfishes, viviparous brotulas, and others. Members of this order have small heads and long slender bodies. They have either smooth scales or no scales, a long dorsal fin and an anal fin that typically runs into the caudal fin. They mostly come from the tropics and subtropics, and live in both freshwater and marine habitats, including abyssal depths. They have adopted a range of feeding methods and lifestyles, including parasitism. The majority are egg-laying, but some are viviparous.

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 ,maximum known standard length are 11 mm. 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.

Blenniiformes suborder of fishes

Blenny is a common name for a type of fish. The term is ambiguous, having been applied to several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", all grouped together under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of Fishes of the World divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes.

Schindleria is a genus of marine fish. It was the only genus of family Schindleriidae, among the Gobioidei of order Perciformes but is now classified under the Gobiidae in the Gobiiformes. The type species is S. praematura, Schindler's fish. The Schindleria species are known generically as Schindler's fishes after German zoologist Otto Schindler (1906–1959), or infantfishes. They are native to the southern Pacific Ocean, from the South China Sea to the Great Barrier Reef off eastern Australia.

Eleotridae family of fishes

Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species. Most species are found in the tropical Indo-Pacific region, but there are also species in subtropical and temperate regions, warmer parts of the Americas and near the Atlantic coast in Africa. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea; as adults, the majority live in freshwater streams and brackish water. One of its genera, Caecieleotris, is troglobitic. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawaii that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically, they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker.

Grahams gudgeon species of fish

Graham's gudgeon, Grahamichthys radiata, is a species of goby of the family Thalasseleotrididae, the only member of the genus Grahamichthys. This species is found in rock pools and in the neritic zone, to 50 metres (160 ft) in depth, where sand or mud is lies around and partially buries rocks, shells, or other objects. It is unusual for a goby, in that it lives in loose schools. The generic name is a compound formed from the surname Graham in honour of David H. Graham who wrote A Treasury of New Zealand Fishes which was published in 1953 and therefore is an allusion to this taxon being endemic to New Zealand and the Greek ichthys meaning "fish".

Gudgeon (fish)

Gudgeon is the common name for a number of small freshwater fish of the families Butidae, Cyprinidae, Eleotridae or Ptereleotridae. Most gudgeons are elongate, bottom-dwelling fish, many of which live in rapids and other fast moving water.

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.

Dartfish subfamily of fishes

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, 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. They are saltwater fish.

Crazy fish species of fish

Butis butis, the crazy fish, duckbill sleeper, or upside-down sleeper, is a species of sleeper goby that are native to brackish and freshwater coastal habitats of the Indian Ocean and the western Pacific Ocean from the African coast to the islands of Fiji. They prefer well-vegetated waters and can frequently be found in mangrove swamps. They are small, drably-colored fish, reaching a maximum length of only 15 cm (5.9 in). They are predatory and are known for their behavior of swimming vertically – or even upside down – while hunting.

Gobiiformes order of fishes

The Gobiiformes are an order of fish that includes the gobies. The order, which was previously considered a suborder of Perciformes, is made up of 2,211 species that are divided into seven different families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are generally small fish and are mostly marine (saltwater) fishes, but roughly 10% of the population inhabit fresh waters. This order is made up of mainly benthic or sand-burrowing fish. Benthic fish live on the bottom of a body of water. Like in most benthic organisms, gobiiforms do not have a gas bladder or swim bladder which keeps them from suspending in the water column, so they must stay on the bottom.

Schindleria praematura, Schindler's fish is a species of neotenic goby which was formerly placed in the monogeneric family Schindleriidae but which is currently classified within the Gobiidae. It is associated with reefs and has an Indo-Pacific distribution from South Africa and Madagascar to Hawaii and the sea mounts of the South Pacific. The generic name and the common name honour the German zoologist Otto Schindler (1906–1959) who described the species.

<i>Pholidichthys</i> genus of fishes

Pholidichthys is a genus of ray-finned fish which consists of two species of the tropical Pacific Ocean. It is the only genus in the family Pholidichthyidae, one of two families in the order Cichliformes.

Dorothea's wriggler, Allomicrodesmus dorotheae, is a species of fish in the monotypic genus Allomicrodesmus which is regarded by some authorities as being in the family Xenisthmidae, the wriggler family, but in the 5th edition of Fishes of the World this is treated as a synonym of the family Eleotridae, sleeper gobies. It is 5 cm (2.0 in) in length. It is known from just two specimens, one from the Great Barrier Reef and the other from the Marshall Islands. It has been collected from a depth of around 10 m (33 ft) in a channel in a reef. The specific name honours Dorothea Bowers Schultz, the wife of Leonard Peter Schultz, who illustrated the monograph in which this species is described, although not this species.

Crystal goby species of fish

Crystallogobius linearis, the crystal goby, is a species of goby native to the Atlantic coasts of Europe and the Mediterranean Sea where it can be found at depths of from 1 to 400 metres. Males of this species grow to a length of 4.7 centimetres (1.9 in) SL while females only reach 3.9 centimetres (1.5 in) SL. This species is the only known member of its genus. The name Crystallogobius comes from the Latin words cristallum, meaning "crystal", and gobius, meaning gudgeon.

Butidae family of fishes

Butidae is a family of sleeper gobies in the order Gobiiformes. The family was formerly classified as a subfamily of the Eleotridae but the 5th Edition of Fishes of the World classifies it as a family in its own right. Molecular phylogenetic analyses have demonstrated that the Butidae are a sister clade to the clade containing the families Gobiidae and Gobionellidae and that the Eleotridae is a sister to both of these clades. This means that the Eloetridae as formerly classified was paraphyletic and that its subfamilies should be raised to the status of families.

Milyeringidae family of fishes

Milyeringidae, the blind cave gobies, is a small family of gobies, in the order Gobiiformes. There are two genera and six species within the family, which is considered to be a subfamily of the Eleotridae by some authorities. Milyeringidae includes one genus (Milyeringa) restricted to caves in the North West Cape region of Australia and the other (Typhleotris) to underground water systems in Madagascar. They are all troglobitic species and have lost their eyes.

Kurtiformes order of fishes

The Kurtiformes consist of two extant families of ray-finned fish, the Indo-Pacific Kurtidae, the nursery fish, with two species and the much more diverse and widespread Apogonidae, the cardinalfishes, the order is part of the Percomorpha clade and is regarded by many authorities as a sister taxon to the Gobiiformes.

<i>Thalasseleotris</i> genus of fishes

Thalasseleotris is a genus of gobies comprising two species in the family Thalasseleotrididae from the south-western Pacific Ocean in the seas off Australia and New Zealand. The generic name is derived from the Greek Thalassa meaning "sea" and the generic name Eleotris as at the time it was named the genus was considered to be in the family Eleotridae.

Atherinomorpha infraseries of fishes, part of the subseries Ovalentaria

The Atherinomorpha is a clade of fishes in the superorder Acanthopterygii, the ray-finned fishes, consisting of three orders. The clade is ranked as an infraseries withn the subseries Ovalentaria, which in turn is ranked within the wider Percomorpha clade.
