Kraemeriinae is a subfamily of ray-finned fish in the family Gobiidae, commonly known as sand darters. [2] They were previously treated as the separate family Kraemeriidae, but were reclassified after molecular analyses found them to be nested within Gobiidae. [3] [4]
These fish are Indo-Pacific, being native to the Indian Ocean to the central Pacific Ocean. They live in sandy shallow pools and are found among coral. One species is restricted to fresh waters of Madagascar. In breeding coloration the male fish has an occelated spot at the rear of the first dorsal fin.
Gobiidae or gobies 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. Most of gobiid fish are relatively small, typically less than 10 cm (3.9 in) in length, and the family 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 9 mm (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 fish for humans, they are of great significance as prey species for other 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.
Anoplopomatidae, the sablefishes, are a small family of ray-finned fishes classified within the order Perciformes. These fishes are found in the North Pacific Ocean.
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.
Hexagrammidae, the greenlings, is a family of marine ray-finned fishes belonging to the suborder Cottoidei in the order Perciformes. These fishes are found in the North Pacific Ocean.
The Hemitripterinae is a subfamily of the scorpaeniform family Agonidae, known as sea ravens or sailfin sculpins. They are bottom-dwelling fish that feed on small invertebrates, found in the northwest Atlantic and north Pacific Oceans. They are covered in small spines.
Apistinae, the wasp scorpionfishes, is a subfamily of venomous, marine ray-finned fishes belonging to the family Scorpaenidae, the scorpionfishes and related species. These fishes are native to the Indian Ocean and the western Pacific Ocean.
Dendrochirus is a genus of marine ray-finned fishes belonging to the family Scorpaenidae, the scorpionfishes. They are mostly known as turkeyfishes or pygmy lionfishes. They are native to the Indian and Pacific Oceans. They are also popular aquarium fish.
Eviota readerae is a species of goby associated with reefs and tide pools. It has a very limited distribution in the southwest Pacific, being found only on the Elizabeth and Middleton Reefs and the Lord Howe Rise in the Tasman Sea.
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".
Naso elegans, the elegant unicornfish, the blonde naso tang, Indian orange-spine unicorn, lipstick surgeonfish, lipstick tang, orangespine unicornfish or smoothheaded unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This species is found in the Indian and western Pacific Oceans.
True gobies were a subfamily, the Gobiinae, of the goby family Gobiidae, although the 5th edition of the Fishes of the World does not subdivide the Gobiidae into subfamilies. They are found in all oceans and a few rivers and lakes, but most live in warm waters. Altogether, the Gobiinae unite about 1149 described species in 160 genera, and new ones are still being discovered in numbers.
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Tomiyamichthys russus, the Ocellated shrimpgoby, is a species of marine ray-finned fish belonging to the family Gobiidae, the typical gobies. This species is found in the Eastern Indian Ocean and Western Pacific Ocean.
Oplopomus is a genus of gobies found in coral reefs of the Indo-Pacific region. It contains two species.
Bothragonus is a genus of marine ray-finned fishes belonging to the family Agonidae, the poachers and related fishes. It is the only genus in monotypic subfamily Bothragoninae. These fishes are found in the northern Pacific Ocean.
Easchmeyer nexus is a species of marine ray-finned fish; it is the only species in the monotypic genus Eschmeyer and monogeneric family Eschmeyeridae. This fish is only known from the Pacific Ocean, near Fiji.
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.
Eviota guttata, the spotted dwarfgoby, is a species of ray-finned fish from the family Gobiidae, the "true gobies". It is found in the western Indian Ocean.
Gymnelinae is a subfamily of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. Most species are found in the North Pacific Ocean but one genus is cosmopolitan, and another is endemic to the Southern Ocean.
Hypsagoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the North Pacific Ocean.
