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.
Rainbowfishes are small, colourful freshwater fishes belonging to the family Melanotaeniidae, found in northern and eastern Australia, New Guinea, Sulawesi and Madagascar.
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.
Mudskippers are any of the 23 extant species of amphibious fish from the subfamily Oxudercinae of the goby family Oxudercidae. They are known for their unusual body shapes, preferences for semiaquatic habitats, limited terrestrial locomotion and jumping, and the ability to survive prolonged periods of time both in and out of water.
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.
Pomatoschistus is a genus of gobies native to fresh, brackish and marine waters of Europe, the eastern Atlantic Ocean and the Mediterranean Sea.
The common goby is a species of ray-finned fish native to fresh and brackish waters along the Atlantic and Baltic Sea coasts of Europe and northern Africa, with a range stretching from Norway to Morocco and Mauritania. It is also found in the Canary Islands. This species reaches a maximum length of 9 centimetres (3.5 in) TL.
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 Benthophilinae are a subfamily of gobies endemic to the Ponto-Caspian region. The subfamily includes about 50 species. The representatives of the subfamily have fused pelvic fins and elongated dorsal and anal fins. They are distinguished from the closely related subfamily Gobiinae by the absence of a swimbladder in adults and location of the uppermost rays of the pectoral fins within the fin membrane.
Sand goby may refer to several species of fishes of Gobioidei:
Oplopomus is a genus of gobies found in coral reefs of the Indo-Pacific region. It contains two species.
Rhinogobiops is a genus of true gobies in the family Gobiidae. It is monotypic, being represented by the single species, Rhinogobiops nicholsii, also known as the blackeye goby, bluespot goby, and crested goby. They are common inhabitants of coral reefs and rocky habitats along the eastern Pacific Ocean coasts of Mexico, the United States, and Canada, although they are hardly noticed, as they often rest motionless near their shelters.
Trypauchen vagina, commonly known as the burrowing goby, is a species of eel goby found in the Indo-Pacific region. It has an elongated body about 20 to 22 cm in length. It is reddish-pink in color and possesses distinctive pouches in the upper edges of its gill covers. It lives in burrows in the silty and muddy bottoms of its marine and brackish habitats. It has reduced eyes that are entirely covered with skin and the anterior portion of its head is protected by thick flesh. Both adaptations aid it in digging its burrows.
Trimma nasa, commonly called the nasal dwarfgoby or nasal pygmy goby, is a species of goby from the Western Pacific. They are small fish, averaging at around 2 cm (0.79 in) in length. They are bright orange and transparent yellow in life, with a white stripe running down from between the eyes to the upper lip and a dark brown spot at the base of the tail fin. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges.
Trimma tevegae, commonly known as the bluestripe pygmygoby or blue-striped cave goby among other names, is a species of goby from the western Pacific. They are small fish, averaging at 2 cm (0.79 in), orange-brown with white undersides in life, with characteristic iridescent blue or lavender stripes on the sides and on top of the body. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges. They are sometimes caught for the aquarium trade, and are also known by hobbyists under the name blue line flagtail goby. The species is named in honor of the schooner Te Vega.
Dotsugobius bleekeri, also known as the dark mangrovegoby, is a species of fish in the family Gobiidae known from brackish estuarine and the adjacent freshwater areas of the eastern Indian Ocean, Andaman Sea and Western Pacific. The generic name honours the Japanese ichthyologist Yoshie Dotsu, whose surname was spelled “Dôtu” in his earlier publications, of Nagasaki University while the specific name honours the Dutch ichthyologist, herpetologist and physician Pieter Bleeker (1819-1878) who was a significant worker on the fish fauna of the Dutch East Indies. This species is placed in the genus Lophogobius by some authorities.
Gnatholepis gymnocara, the Nakedcheek sandgoby, is a small species of ray-finned fish in the subfamily Gobionellinae. The Naked cheek sandgoby is found primarily in the Indian Ocean along the coast of Australia.
Papuligobius uniporus is a species of small goby in the subfamily Gobionellinae. It is also the type species of the genus Papuligobius.
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.
