Trypauchen is a genus of burrowing gobies native to the Indo-Pacific region. It is classified under the subfamily Amblyopinae of the family Gobiidae. The name is derived from Ancient Greek τρύπα (trupa, "hole") and αυχενος (aukhenos, "neck"), referring to the distinctive opercular pouches of the members of the genus.
There are currently two recognized species in this genus:
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.
Mudskippers are amphibious fish, presently included in the family Oxudercidae, in the subfamily Oxudercinae. There are 32 living species of mudskipper.
Exyrias is a genus of gobies mostly native to marine waters of the Indian Ocean and the western Pacific Ocean with one freshwater species (E. volcanus) known from the Philippines.
Odontamblyopus rebecca is a species of eel goby native to marine and brackish waters of Vietnam. This species can reach a length of 14.1 centimetres (5.6 in) SL. This species is mostly known from several specimens collected from a fish market in Haiphong, Vietnam. The specific name honours Edward O. Murdy's wife Rebecca Rootes.
A blind fish is a fish without functional eyes. Most blind fish species are found in dark habitats such as the deep ocean, deep river channels and underground.
Oligolepis keiensis also known as the Kei goby is a species of goby native to marine and brackish waters along the coasts of Mozambique, South Africa, Madagascar and the Seychelles. This species can reach a length of 7 centimetres (2.8 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.
Periophthalmus is a genus of fish in the family Gobiidae, native to coastal mangrove wood- and shrubland in the Indo-Pacific region, except for P. barbarus from the Atlantic coast of Africa. It is one of the genera commonly known as mudskippers. All Periophthalmus species are aggressive and territorial.
Zappa confluentus, the New Guinea slender mudskipper, endemic to New Guinea where it is only known from the lower parts of the Fly, Ramu and Bintuni Rivers. It is found on mudflats adjacent to turbid rivers. This species can reach a length of 4.4 centimetres (1.7 in) SL.
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.
Gobiodon histrio, the Broad-barred goby, is a species of goby native to the Indian Ocean from the Red Sea to the western Pacific Ocean to southern Japan, Samoa and the Great Barrier Reef. This species is a reef dweller, being found at depths of from 2 to 15 metres. It can reach a length of 3.5 centimetres (1.4 in) TL. This species can also be found in the aquarium trade.
Pseudogobiopsis is a genus of fish in the goby family, Gobiidae. They are native to fresh and brackish waters of southern and southeastern Asia. The genus is mainly distinguished by the number and arrangement of fin rays and spines, headpores, and sensory papillae, the large mouths of the males, a fleshy or bony flange on the pectoral girdle, and the shape of the genital papilla.
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.
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.
Trypauchen pelaeos is a species of eel goby found in Indochina and southern China. It is reddish in color and has an elongated body with the anal, caudal, and the two dorsal fins fused together with membranous structures. It is similar in appearance and habits to the closely related burrowing goby, Trypauchen vagina.
Boleophthalmus dussumieri is a species of mudskipper native to the Indian Ocean where it can be found on mudflats in fresh, brackish and marine waters of Iraq, Pakistan and India as well as probably in Bangladesh. This species can reach a length of 18.7 centimetres (7.4 in) TL.
Papuligobius is a genus of fish in the goby subfamily, Gobionellinae, native to Southeast Asia. It was erected in 2003 to house the species P. uniporus, newly described from Laos. A second species, P. ocellatus, was transferred from genus Rhinogobius at the same time.
Pseudogobius is a genus of fish in the goby family, Gobiidae. It is widely distributed in tropical and temperate regions of the Indian and western Pacific Oceans. Species occur in freshwater and estuarine habitat types, such as mangroves and seagrass beds.
Biendongella is a genus of fish in the subfamily Gobionellinae native to the South China Sea. The generic name is formed by adding the diminutive suffix ella to the Vietnamese name for the South China Sea, Bien Dong.
Sovvityazius acer is a species of fish in the family Gobiidae found in the Philippines. This species is the only member of the genus Sovvityazius.
