Nannoperca Australis
The southern pygmy perch (''Nannoperca australis''), also known as the Tasmanian pygmy perch, is a species of freshwater ray-finned fish, a temperate perch from the family Percichthyidae which is native to southeastern Australia and Tasmania. Description The southern pygmy perch has an oblong and moderately compressed body with a convex dorsal profile and a straight ventral profile. It has a large head the top of which bulges slightly and a blunt snout. It has a slightly oblique, terminal mouth which is protractile with the maxilla reaching to a level near the centre of the eye.

The western pygmy perch (''Nannoperca vittata'') is a species of temperate perch endemic to southwestern Australia. Description The Western pygmy perch is a small fish with an olive, brown and green mottled body with tow orange stripes along the flanks. In the breeding season the males develop brighter colouration with golden mottling along the flanks, an reddish-orange abdomen and the fins darken. The females develop a bluish colour when breeding. It can reach TL. Distribution The Western pygmy perch is endemic to the south-western coastal drainages of Western Australia. Its range extends from the Waychinicup River east of Albany to the Arrowsmith River north of Perth. It occurs in the majority of the river drainages within its range, as well as in lakes near the south coast. Habitat and biology The Western pygmy perch is found predominantly in lakes, streams, and swamps, and can withstand a degree of brackishness. They have a preference for living among vegetation in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nannoperca Oxleyana
''Nannoperca oxleyana'', commonly known as the Oxleyan pygmy perch, is a species of temperate perch endemic to Australia. It occurs in the coastal drainages of eastern Australia, being found in dune lakes, ponds, creeks, and swamps with plentiful vegetation to provide shelter. The waters in which it lives are often dark and acidic. It preys upon aquatic insects and their larvae, as well as planktonic crustaceans and even algae. This species can reach SL, though most do not exceed .

Temperate Perch
The members of the family Percichthyidae are known as the temperate perches. They belong to the order Perciformes, the perch-like fishes. The name Percichthyidae derives from the Latin ''perca'' for perch and Ancient Greek ἰχθύς, ''ichthys'' for fish. Classification The temperate perches are closely related to the temperate basses of the family Moronidae, and older literature treats the latter as belonging to the family Percichthyidae. Australian freshwater percichthyids were once placed in the marine grouper family, Serranidae, and the two families are thought to be closely related. Almost 40 species of percichthyids are now recognised, grouped in 11–12 genera. Most but not all are exclusively freshwater fishes. They are mainly found in Australia, but species are also found in southern South America (''Percichthys''). More recently the Chinese perches have been classified in the separate family Sinipercidae while the genus ''Percilia'' has been found not to be close ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Taxa Named By Albert Günther
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 the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Australia
Freshwater fish of Australia are limited to approximately 280 species, even though the Australian continent is larger than the contiguous United States. The small scale of species found in Australian inland waters is in some part due to the dry conditions of the continent. Rainfall is sporadic over much of the continent, and fish cannot live in many of the desert regions of South Australia and Western Australia. Most freshwater species are found in tropical or subtropical regions. A large proportion of freshwater species are endemic to Australia. The family Percicthyidae (temperate perches) and other families suspected in reality to lie within it (e.g. Gadopsidae, Nannopercidae) have risen to prominence in and dominate many of its freshwater systems, in contrast to the Northern Hemisphere where freshwater fish faunas are overwhelmingly dominated by the carp family, Cyprinidae. (No cyprinid species is native to Australia). Due to the illegal introduction of carp (''Cyprinus carpio' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
