Hyrtl's Catfish
''Neosilurus hyrtlii'', commonly known as Hyrtl's catfish or Glencoe tandan, is a species of catfish found across northern Australia, from the Pilbara to southeastern Queensland. Taxonomy ''Neosilurus hyrtlii'' has been given many common names, including common eel-tail catfish, Glencoe tandan, Hyrtl's tandan, inland catfish, moonfish, moony, Morton's tandan, mottled tandan, salmon catfish, silver moonfish, straight-backed catfish, white tandan, yellow fin tandan and yellow-finned catfish. Austrian naturalist Franz Steindachner described the species in 1867, from the Fitzroy River in Queensland. Description This catfish is generally between in length, though larger fish to 30 cm long are not uncommon. Fish of up to have been recorded from the Alligator River. Female fish are a little larger than male fish. The head is wide and mildly flattened with four pairs of barbels. It has a sturdy dorsal spine, the inside edge of which is serrated. Large fish are dark brown or gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University. Steindachner took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooper Creek
The Cooper Creek (formerly Cooper's Creek) is a river in the Australian states of Queensland and South Australia. It was the site of the death of the explorers Burke and Wills in 1861. It is sometimes known as the Barcoo River from one of its tributaries and is one of three major Queensland river systems that flow into the Lake Eyre basin. The flow of the creek depends on monsoonal rains falling months earlier and many hundreds of kilometres away in eastern Queensland. It is in length. History Indigenous Australians have inhabited the area for at least 50,000 years, with over 25 tribal groups living in the Channel Country area alone. A vast trade network had been established running from north to south with goods such as ochre sent north with shells and pituri moved south. Birdsville was once a major meeting place for conducting ceremonies and trade. Charles Sturt named the river in 1845 after Charles Cooper, the Chief Justice of South Australia. It was along Cooper Creek t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venomous Fish
Venomous fish are species of fish which produce strong mixtures of toxins harmful to humans (called venom) which they deliberately deliver by means of a bite, sting, or stab, resulting in an envenomation. As a contrast, poisonous fish also produce a strong toxin, but they do not bite, sting, or stab to deliver the toxin, instead being poisonous to eat because the human digestive system does not destroy the toxin they contain in their bodies. Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom.Poisonous vs. Venomous fish: What’s the difference? Reef Biosearch. Retrieved 17 July 2009. There are at least 1200 species of venomous fish, Smith WL and Wheeler WC (2006 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
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 s ... [...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] |
Neosilurus
''Neosilurus'' is a genus of eeltail catfishes native to Australia and New Guinea. It is one of the largest genus of fresh water plotosid. Species There are currently 11 recognized species in this genus: * '' Neosilurus ater'' (Perugia, 1894) (Narrowfront tandan) * ''Neosilurus brevidorsalis'' ( Günther, 1867) (Shortfin tandan) * '' Neosilurus coatesi'' (Allen, 1985) * '' Neosilurus equinus'' (Weber, 1913) (Southern tandan) * '' Neosilurus gjellerupi'' (Weber, 1913) (Northern tandan) * ''Neosilurus gloveri'' Allen & Feinberg, 1998 (Dalhousie catfish) * '' Neosilurus hyrtlii'' Steindachner, 1867 (Glencoe tandan) * '' Neosilurus idenburgi'' (Nichols, 1940) (Idenburg tandan) * '' Neosilurus mollespiculum'' Allen & Feinberg, 1998 (Soft-spined catfish) * '' Neosilurus novaeguineae'' (Weber, 1907) (New Guinea tandan) * '' Neosilurus pseudospinosus'' Allen Allen, Allen's or Allens may refer to: Buildings * Allen Arena, an indoor arena at Lipscomb University in Nashville, Tennessee ...

Chironomidae
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mary River (Queensland)
The Mary River (Kabi Kabi: ''Moocooboola'') is a major river system located in the South East and Wide Bay–Burnett regions of Queensland, Australia. Etymology The river was traditionally named ''Moocooboola'' by the indigenous Australian Kabi people. The river was named ''Wide Bay River'' on 10 May 1842 by early European explorers, Andrew Petrie and Henry Stuart Russell. The official name was changed on 8 September 1847 (prior to Queensland becoming a separate colony) by Charles Augustus FitzRoy, then Governor of New South Wales, to ''Mary River'' — after his wife Lady Mary Lennox (15 August 1790 to 7 December 1847). History The Mary River was used for rafting timber during the early years of European land settlement, and the discovery of gold at Gympie in 1867 brought an inflow of miners and pastoralists. Alluvial flats along the Mary River and some of its tributaries were used for cropping, and there was small-time dairying in the 1880s. Course and features The ...

Finke River
The Finke River, or ''Larapinta'' (Arrernte), is a river in central Australia, one of four main rivers of the Lake Eyre Basin and thought to be the oldest riverbed in the world. It flows for only a few days a year and when this happens, its water usually disappears into the sands of the Simpson Desert, rarely if ever reaching Lake Eyre. Geography The source of the Finke River is in the Northern Territory's MacDonnell Ranges which flows through central Australia, the name Finke River is first applied at the confluence of the Davenport and Ormiston Creeks, just north of Mount Zeil. From here the river meanders for approximately to the western edge of the Simpson Desert in northern South Australia. It flows through the West MacDonnell and Finke Gorge National Parks. Usually the river is a string of waterholes, but it can become a raging torrent during rare flood events. In extreme events, water from the Finke River flows into the Macumba River, which empties into Lake Eyre, a tot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulloo River
The Bulloo River is an isolated drainage system in western Queensland, central Australia. Its floodplain, which extends into northern New South Wales, is an important area for waterbirds when inundated. It comprises most of the Bulloo-Bancannia drainage basin. Description The Bulloo is the only river in the region not part of either the Murray–Darling basin or the Lake Eyre basin; instead it flows into several ephemeral lakes which are blocked by low hills from reaching the Lake Frome, the Paroo River or the Lake Bancannia systems. In its lowest reaches, which extend to near Tibooburra, New South Wales, is the distributary known as Bella Creek. It is believed that in past wet periods the Bulloo has had connections to Lake Frome because its fish fauna resembles that of the Lake Eyre basin rather than that of the Murray–Darling basin. Several tributaries flow into the Bulloo in its upper reaches, the largest being Blackwater Creek. Ranges of low hills prevent the lower ...

Georgina River
The Georgina River is the north-westernmost of the three major rivers of the Channel Country in Central West Queensland, that also flows through a portion of the Northern Territory, in central Australia. Part of the Lake Eyre basin, the Georgina flows in extremely wet years into Lake Eyre. The river is named in honour of Georgina Mildred Kennedy, the daughter of Queensland governor Arthur Kennedy. The river was originally called the Herbert River before being given its current name in 1890 to avoid confusion with the other river in Queensland that bears that name. Geography With its headwaters rising in the Barkly Tableland, north of Camooweal in Queensland, and in the extreme east of the Northern Territory beyond Tennant Creek and to the south draining the northern slopes of the Macdonnell Ranges, the Georgina is formed from several smaller streams over a wide area of north-western Queensland and the eastern Northern Territory. From source to mouth, the Georgina is joined b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
