Caragobius is a genus of gobies native to Asia and the western Pacific Ocean.
There are currently three recognized species in this genus: [1]
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.
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.
Favonigobius is a genus of gobies native to fresh, brackish and marine waters around the Indian Ocean and the western Pacific Ocean. Commonly called "sand gobies", this term more alternatively refers to the family Kraemeriidae, a relative of the true gobies.
Gobiodon is a genus of gobies also known as coral gobies or "clown gobies". Generally, coral gobies, unlike the rest of the family Gobiidae, are not burrowers, but instead prefer to inhabit the branches of certain Acropora or similar hard corals.
Brachygobius is a small genus of gobies. They are popular aquarium fish where a number of species are sold as bumblebee gobies because their colours are similar to those of bumblebees.
Gobius is a genus of fish in the family Gobiidae native to fresh, brackish and marine waters of and around Europe, Africa and Asia. It contains the typical gobies, being the type genus of the formerly recognised subfamily Gobiinae and family and the namesake genus of its order Gobiiformes.
Knipowitschia is a genus of marine, fresh and brackish water gobies native to Eurasia. The genus name almost certainly honours Nikolai Mikhailovich Knipovich (1862-1938), a biologist who led a number of expeditions to the Caspian Sea.
Pomatoschistus is a genus of gobies native to fresh, brackish and marine waters of Europe, the eastern Atlantic Ocean and the Mediterranean Sea.
Redigobius is a genus of fish in the goby family, Gobiidae, known commonly as dualspot gobies. They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.
Stenogobius is a genus of fish in the goby subfamily, Gobionellinae. They are native to fresh, brackish and marine waters along the coasts of the Indian and Pacific Oceans. They are known commonly as coastal stream gobies.
Elacatinus is a genus of small marine gobies, often known collectively as the neon gobies. Although only one species, E. oceanops, is technically the "neon goby," because of their similar appearance, other members of the genus are generally labeled neon gobies, as well. Except for a single East Pacific species, all reside in warmer parts of the West Atlantic, including the Caribbean and Gulf of Mexico. They are known for engaging in symbiosis with other marine creatures by providing them cleaning service that consists of getting rid of ectoparasites on their bodies. In return, Elacatinus species obtain their primary source of food, ectoparasites.
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".
The tadpole-gobies (Benthophilus), also called pugolovkas, are a genus of Ponto-Caspian fishes in the family Gobiidae.
Proterorhinus is a genus of fishes, known as the tubenose gobies. These gobiid fish are native to Eurasia where they occur in the region of the Caspian and Black seas, inhabiting marine, brackish and fresh waters. The species Proterorhinus semilunaris was introduced to the St. Clair River in Michigan during the late 1990s. Until recently, the genus was considered monotypic, comprising only the tubenose goby. Following molecular and further morphological investigations it has been split into several taxa, with distinct distributions in marine vs. fresh waters and in the Black Sea vs. Caspian Sea basins.
Chromogobius is a small genus of gobies native to the eastern Atlantic Ocean through the Mediterranean and Adriatic seas to the Black Sea.
Tridentiger is a genus of fish in the subfamily of gobies called the Gobionellinae, known commonly as the tripletooth gobies.
Rhinogobius flumineus, commonly known as the lizard goby or kawa-yoshinobori, is a species of goby endemic to Japan where it is found in the mid- to upper reaches of fast-flowing rivers. This species can reach a length of 7 centimetres (2.8 in) TL.
The blind goby is a species of fish in the goby family, the only species in the genus Typhlogobius. It is native to the coastlines of southern California in the United States and Baja California in Mexico, where it commonly inhabits the burrows of shrimp of the genus Callianassa. The adult of the species is completely blind and lacks pigmentation, while the juvenile has rudimentary eyes that help it find the shrimp burrows. This species can reach a length of 8.3 centimetres (3.3 in) TL.
Amblyopinae is a subfamily of elongated mud-dwelling gobies commonly called eel gobies or worm gobies; it has been regarded as a subfamily of the family Gobiidae, while the 5th edition Fishes of the World classifies it as a subfamily of the family Oxudercidae. The members in the subfamily have two dorsal fins that are connected by a membranous structure and their eyes are highly reduced in size. They are usually pink, red, or purple in coloration.
Chriolepis is a genus of gobies native to the Atlantic and Pacific coasts of the Americas.
