Gobiomorphus
''Gobiomorphus'' is a genus of fishes in the family Eleotridae native to New Zealand and Australia. They are typically small, Benthic zone, 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. Articulated fossil skeletons of an indeterminate ''Gobiomorphus'' were previously identified from the Early Miocene of New Zealand (St Bathans fauna, St. Bathans fauna of Bannockburn Formation). However, more recent studies have found these to represent a distinct genus, ''Mataichthys'', which was significantly larger than ''Gobiomorphus''. However, small-sized fossil Otolith, otoliths from the same deposits, if not those of juvenile ''Mataichthys'', could potentially represent those of ''Gobiomorphus''. Species The recognized species in this genus are: * ''Gobiomorphus alpinus'' (Gerald Stokel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobiomorphus Huttoni
The redfin bully (''Gobiomorphus huttoni'') is a species of freshwater fish in the family Eleotridae endemic to New Zealand. Being amphidromous, it spends part of its life cycle at sea. Males have distinctive bright red patterns and stripes on their fins. Adults grow to an average of total length, with a maximum of . Description ''G. huttoni'' was recognised as a distinct species in 1894, but has had many name changes. The current specific name "huttoni" refers to New Zealand biologist Sir Frederick W. Hutton. This is one of seven species of native bullies found in a range of freshwater habitats in New Zealand. Male redfin bullies are the most colourful freshwater fish in New Zealand, with bright red markings on the dorsal, anal, and tail fins, as well as the body and cheeks. Additionally, males have a bluish-green stripe on the outer edge of the first dorsal fin. Only the males have the red colouring; the females have the same patterns, but with brown in place of red.

Gobiomorphus Hubbsi
The bluegill bully (''Gobiomorphus hubbsi'') is a fish in the family Eleotridae that is endemic to New Zealand. It lives in shallow, fast-flowing riffles and torrents, where it forages and shelters amongst the gravels. It has a similar distribution to the other endemic riffle specialist, the torrentfish. It can be found up to inland, and from sea level up to an elevation of . The bluegill bully is the smallest of the Eleotrids, commonly reaching only . It is named for the bright blue edge to the operculum or gill cover, which is present in both sexes. It eats aquatic invertebrates and has an upturned mouth, allowing them to pick invertebrates off the stones above them. The species is crepuscular with the most active times for feeding at dawn and dusk. They feed predominantly on ''Deleatidium'' mayfly nymphs. They are amphidromous (meaning that they migrate from fresh water to the seas, or vice versa, but not for the purpose of breeding). The eggs are laid in fresh water and on ...

Gobiomorphus Gobioides
The giant bully (''Gobiomorphus gobioides''), tītarakura, or tīpokopoko (Māori), is a species of fish in the family Eleotridae endemic to New Zealand. Description This is the largest species of bully and it can reach more than in length, but most are . Adults are generally found near the coast in freshwater, tidal or estuarine habitats. The breeding behavior is poorly known, but the species is considered diadromous and it is suspected that the larvae spend time in the sea. It is very similar to the common bully (which can reach up to ), but it has six dorsal Dorsal (from Latin ''dorsum'' ‘back’) may refer to: * Dorsal (anatomy), an anatomical term of location referring to the back or upper side of an organism or parts of an organism * Dorsal, positioned on top of an aircraft's fuselage The fus ... spines, where the common bully usually has seven.

Gobiomorphus Coxii
''Gobiomorphus coxii'', or Cox's gudgeon, is a species of sleeper goby in the family Eleotridae which is native to the upland rivers of south eastern Australia. Description ''Gobiomorphus coxii'' is dark brown to greenish-brown in colour on the back and flanks, this colouration fades to pale brown or cream on the underside. The scales on the lower flanks are mottled with blue, gold and yellow and there is a single black spot above the base of the pectoral fin. The juveniles have series of elongated blotches on their flanks which merge as they nature to create a wide, dusky, mid-lateral stripe. The head is dark brown with the lower jaw and throat often coloured black and with two indistinct, dark stripes radiating from the rear of the orbit across operculum. Its fins vary from colourless to blackish-grey and the dorsal fins have between one and three dark stripes with a yellow or orange background colour. The margins of the fin are frequently fin margins yellow and the caudal fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobiomorphus Cotidianus
The common bully (''Gobiomorphus cotidianus''), or toitoi (Māori), is a fish endemic to New Zealand, and is present throughout the country. There are three other bully species that can be confused with common bullies. There are few characteristics of the common bully that separate it from other species. Vertical lines present on the cheek are a good defining characteristic, along with the location of head pores and scale patterns on the head although these are hard to establish when seen in the wild. It is an amphidromous fish meaning it is able to survive in marine and fresh water environments. It is a small fish only growing as big as 15 cm. It can live in marine, fresh water or brackish water habitats and generally lives in benthic zones. Some populations venture into the sea and occur in coastal rivers and streams while other land-locked populations have established in many shallow mainland lakes. They generally prefer moderate to slow moving water which means they are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobiomorphus Australis
''Gobiomorphus australis'', the striped gudgeon, is a fish in the family Eleotridae Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species.

It can be found in a wide variety of habitats from clear streams with rapid currents to muddy stillwaters such as ponds and waterholes. Juveniles are common in estuaries near rocks, submerged logs and among vegetation. They are good climbers and are able to clamber over wet rocky surfaces such as rapids and waterfalls. ''G. australis'' is a carnivorous species which preys on a wide range of prey including aquatic insects, molluscs and crustaceans. The spawn in the late austral summer when the water reaches 21°C.

Gerald Stokell
Gerald Stokell (20 June 1890 – 10 July 1972) was a New Zealand amateur ichthyology, ichthyologist.Journal of the Royal Society of New Zealanp 324/ref> Early life Stokell was born at Prebbleton, near Christchurch, New Zealand, on 20 June 1890 to Edmund Stokell and Jane (Née Pasche). He lived there for his whole life. He attended List of schools in Canterbury, New Zealand, Broadfields Primary School, and was a keen trout angler. Interest in freshwater fish A keen angler, Stokell wrote a series of studies on trout in Lake Ellismere. Through this interest in angling, he also came across native fish species, but was unable to identify them due to a lack of published information. From 1938 onwards he began publishing papers on them, describing species and detangling the many names that had accrued. He described 10 species that are still accepted, although others turned out to be junior Synonym (taxonomy)#Zoology, synonyms. Species described * ''Galaxias paucispondylus'' (1938) alpin ...

Eleotridae
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.Helfman, G.S., Collette, B.B. & Facey, D.E.
