Pseudomugil Mellis
The honey blue-eye (''Pseudomugil mellis'') is an endangered species of fish in the subfamily Pseudomugilinae. It is Endemism, endemic to southeastern Queensland, Queensland, Australia, where it is found in mildly acidic, often tannin-stained, ponds and streams in wallum habitat. Taxonomy Previously considered a colour variant of the related pacific blue-eye (''Pseudomugil signifer''), the honey blue-eye was described by Gerald R. Allen and Walter Ivantsoff in 1982. The species name is derived from the Latin word ''mel'' "honey". It is markedly smaller than its close relative. It was confirmed genetically as distinct in a molecular study of it and the Pacific blue-eye in 2004. Description The honey blue-eye is a small, pale honey coloured fish that can attain up to in length as an adult, with the largest recorded being a male of . As the common name suggests, the honey blue-eye has blue eyes. It has blue cheeks and a single fine midlateral line running along its body from the ti ...

Taxa Named By Walter Ivantsoff
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and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu.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 intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Fauna Of Australia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Queensland
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. Fresh water i ...

Pseudomugil
''Pseudomugil'' is a genus of fish in the subfamily Pseudomugilinae endemic to Australia and New Guinea, where they are found in freshwater rivers and streams and bodies of brackish water. Description Members of this genus have slender bodies and two dorsal fins. They are usually sexually dimorphic.Saeed, B., Ivantsoff, W. & Allen, G.R. (1989): Taxonomic Revision of the Family Pseudomugilidae (Order Atheriniformes). ''Australian Journal of Marine and Freshwater Research, 40 (6): 719-787.'' The name of this genus is a combination of ''pseudo'' meaning "false" and ''mugil'' meaning "mullet", referring to the resemblance of the body shape of this genus to that of the unrelated mullets. Species There are currently 16 recognized species in this genus: * '' Pseudomugil connieae'' ( G. R. Allen, 1981) (Popondetta blue-eye) * '' Pseudomugil cyanodorsalis'' G. R. Allen & Sarti, 1983 (Neon blue-eye) * '' Pseudomugil furcatus'' Nichols, 1955 (Fork-tail blue-eye) * '' Pseudomugil gertruda ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Platyfish
The southern platyfish, common platy, or moonfish (''Xiphophorus maculatus'') is a species of freshwater fish in family (biology), family Poeciliidae of order (biology), order Cyprinodontiformes. A live-bearing aquarium fish, live-bearer, it is closely related to the green swordtail (''X. hellerii'') and can interbreed with it. It is native to an area of North America, North and Central America stretching from Veracruz, Mexico, to northern Belize. The southern platyfish grows to a maximum overall length of . Sexual dimorphism is slight, the male's caudal fin being more pointed. The anal fin of the male fish has evolved into a gonopodium, a stick-shaped organ used for reproduction. The female southern platyfish's anal fin is fan shaped. Wild varieties are drab in coloration, lacking the distinctive dark lateral line common to many ''Xiphophorus'' species. ''X. maculatus'' prefers slow-moving waters of canals, ditches, and warm springs. Omnivorous, its diet includes both pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Swordtail
The green swordtail (''Xiphophorus hellerii'') is a species of freshwater/brackish fish in family Poeciliidae of order Cyprinodontiformes. A live-bearer, it is closely related to the southern platyfish or 'platy' (''X. maculatus'') and can crossbreed with it. It is native to an area of North and Central America stretching from Veracruz, Mexico, to northwestern Honduras. Description The male green swordtail grows to a maximum overall length of and the female to . The name 'swordtail' is derived from the elongated lower lobe of the male's caudal fin (tailfin). Sexual dimorphism is moderate, with the female being larger than the male, but lacking the 'sword'. The wild form is olive green in color, with a red or brown lateral stripe and speckles on the dorsal and, sometimes, caudal fins. The male's 'sword' is yellow, edged in black below. Captive breeding has produced many color varieties, including black, red, and many patterns thereof, for the aquarium hobby. All varieties sha ...
