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 o ...

Gerald Stokell
Gerald Stokell (20 June 1890 – 10 July 1972) was a New Zealand amateur 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 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 synonyms. Species described * ''Galaxias paucispondylus'' (1938) alpine galaxias * '' Gobiomorphus breviceps'' (1939) upland bully * '' Galaxias prognathu ...

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.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torrentfish
The torrentfish (''Cheimarrichthys fosteri''), or panoko (Māori), is an amphidromous freshwater fish that is endemic to New Zealand. Torrentfish are well adapted to life in shallow, fast-flowing riffles and rapids. They grow to a maximum of in total length, but more commonly reach . Description Torrentfish are stocky, with a flattened underside, arched back and a broad, downward-tapering head with eyes set high. The lower jaw is very undercut and is surrounded by a fleshy upper lip – an adaptation for picking invertebrates off the surface of stones. The fins are very robust. The pectoral fins are very large and triangular, angled so that water flowing over them presses the fish against the riverbed, helping them to stay in position in fast-flowing water. The pelvic fins are set underneath the head. The dorsal and anal fins have very long bases, the dorsal fin extending for nearly half of the body length. The tail fin is short and truncated or slightly forked, suited to sudden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crepuscular Animal
In zoology, a crepuscular animal is one that is active primarily during the twilight period, being matutinal, vespertine, or both. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daylight and of darkness, respectively. Some crepuscular animals may also be active by moonlight or during an overcast day. Matutinal animals are active only before sunrise, and vespertine only after sunset. A number of factors impact the time of day an animal is active. Predators hunt when their prey is available, and prey try to avoid the times when their principal predators are at large. The temperature at midday may be too high or at night too low. Some creatures may adjust their activities depending on local competition. Etymology and usage The word ''crepuscular'' derives from the Latin '' crepusculum'' ("twilight"). Its sense accordingly differs from diurnal and nocturnal behavior, which respectively peak during hours of daylight and dar ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Movements are associated with ocean currents and with the availability of food in different areas at different times of year. The migratory movements m ...

Critter Of The Week
''Critter of the Week'' is a weekly RNZ National programme about endangered and neglected native plants and animals of New Zealand. Beginning in 2015, ''Critter of the Week'' is an approximately 15-minute discussion between Nicola Toki of the Department of Conservation and host Jesse Mulligan on an "uncharismatic and lovable" New Zealand species. The topic of spotlighting uncharismatic species was raised in an interview by Mulligan in April 2015, and the programme originated in a discussion between Mulligan and Toki about threatened bird conservation, in which she lamented a lack of attention and corporate funding for species such as the '' Smeagol'' gravel maggot. The first episode, airing 2 October 2015, featured the New Zealand bat fly. Each week's broadcast is supported by improving the Wikipedia article for the species in question. The show currently airs on Friday afternoons. In 2018, artist Giselle Clarkson designed t-shirts featuring a selection of species that had a ...

Gobiomorphus
''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. Species The recognized species in this genus are: * '' Gobiomorphus alpinus'' ( Stokell, 1962) (Tarndale bully) * '' Gobiomorphus australis'' ( Krefft, 1864) (striped gudgeon) * '' Gobiomorphus basalis'' (Gray, 1842) (Cran's bully) * '' Gobiomorphus breviceps'' (Stokell, 1939) (upland bully) * '' Gobiomorphus cotidianus'' ( McDowall, 1975) (common bully) * '' Gobiomorphus coxii'' (Krefft, 1864) (Cox's gudgeon) * '' Gobiomorphus gobioides'' (Valenciennes Valenciennes (, also , , ; nl, label=also Dutch, Valencijn; pcd, Valincyinnes or ; la, Valentianae) is a commune in the Nord department, Hauts-de-Fr ...

Taxa Named By Gerald Stokell
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
