Philypnodon is a genus of fishes in the family Eleotridae endemic to Australia and the coastal waters around it.
Two species in this genus are recognized, [1] [2] though molecular studies indicate another undescribed species similar to the dwarf flathead gudgeon from the Lang Lang River in Victoria. [3]
A flathead is one of a number of small to medium fish species with notably flat heads, distributed in membership across various genera of the family Platycephalidae. Many species are found in the Indo-Pacific, especially most parts of Australia where they are popular sport and table fish. They inhabit estuaries and the open ocean. Flathead can grow at least 1 metre (3.3 ft) in length and 18 kilograms (40 lb) in weight, with dusky flathead being the biggest, although fish this size are seldom caught.
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.
The western carp gudgeon is one of several carp gudgeon species. Carp gudgeons are very small perciform fish found in the Australian Murray-Darling River system, mainly in lowland environments, but some have been observed in upland environments. They are often found in small creeks, as well as billabongs and the edges of larger rivers. They prefer water 1 to 2 m deep with aquatic weed and structure provided by rocks or sunken timber.
The yellow-billed spoonbill is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is native to Australia, and is a vagrant to New Zealand, Lord Howe Island and Norfolk Island.
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.
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.
Hypseleotris is a genus of fishes in the family Eleotridae. Most are from fresh water in Australia and New Guinea, but species in fresh and brackish water are found around islands in the western Indian Ocean, southern and eastern Africa, southern and eastern Asia, and Pacific islands. The largest species reaches a length of 12 cm (4.7 in). They are sometimes seen in the aquarium trade; especially H. compressa. In Australia they are known as carp gudgeons.
The Mitchell gudgeon is a species of fish in the family Eleotridae endemic to the Kimberley region of Australia, where it is only known from the Mitchell River system. This species can reach a length of 4 cm (1.6 in). The specific name honours the ichthyologist J. Barry Hutchins of the Western Australian Museum, who collected the type.
Kimberleyeleotris is a genus of fishes in the family Eleotridae endemic to Australia, where they are only known from rivers in the Kimberley region of Western Australia.
Milyeringa is a genus of blind cavefish from the Cape Range and Barrow Island, northwestern Australia. Although traditionally considered to belong to the family Eleotridae, studies show that they represent a distinct and far-separated lineage together with the Typhleotris cavefish from Madagascar, leading some to move them to their own family, Milyeringidae. The generic name is taken from Milyering which is 20 miles (32 km) southwest of Vlamingh Head in the North West Cape of Western Australia, the type locality for Milyeringa veritas.
Mogurnda is a genus of freshwater fishes in the family Eleotridae native to eastern and northern Australia and New Guinea. Several species are endemic to Lake Kutubu in Papua New Guinea.
Oxyeleotris is a genus of sleeper gobies mostly restricted to Australia and New Guinea, though some are found in Southeast Asia.
Xenisthmus is the most well-known genus in the family Xenisthmidae, which is regarded as a synonymous with the Eleotridae, a part of Gobiiformes. These small to very small fish are known as wrigglers, and live in reefs and among rubble in the Indo-Pacific.
Belobranchus belobranchus, the throat-spine gudgeon, is a species of fish in the family Eleotridae native to Indonesia, the Philippines, New Guinea, Timor-Leste, Solomon Islands, New Caledonia and Fiji where it can be found in fresh and brackish water in coastal streams and estuaries. This species grows to a length of 19.5 cm (7.7 in). This species was the only known member of its genus, until Belobranchus segura was described in 2012.
Erotelis is a genus of fishes in the family Eleotridae native to the fresh, marine, and brackish coastal waters of the Americas.
Gobiomorphus is a genus of fishes in the family Eleotridae native to New Zealand and Australia. They are typically small, benthic fishes with large, rounded fins and two dorsal fins. Many have an amphidromous lifecycle: the eggs are laid in fresh water, but the fry are dispersed to sea soon after hatching, and grow there for several months before returning to fresh water.
The dwarf flathead gudgeon is a species of sleeper goby endemic to eastern Australia.
The flathead gudgeon is a species of fish in the family Eleotridae endemic to eastern Australia.
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.
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. 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. 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. The word goby derives from the Latin gobius meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are called "gudgeons", especially in Australia.
