Bovichtus Angustifrons
''Bovichtus angustifrons'', the dragonet, horny, horny thornfish, marblefish, thornfish or variegated marblefish, is a species of marine ray-finned fish, a temperate icefish or thornfish, belonging to the family Bovichtidae. It is endemic to southeastern Australia and Tasmania on rocky reefs in shallow waters. Taxonomy ''Bovichtus angustifrons'' was first formally described in 1913 by the British ichthyologist Charles Tate Regan with the type locality given as Tasmania. The specific name ''angustifrons'' is a compound of ''angustus'' which means narrow and ''frons''meaning "front", "face" or "brow", a reference to the narrower space between the eyes in comparison with '' B. diacanthus'' and '' B. variegatus''. Description ''Bovichtus angustifrons'' has a large head and a thick anterior part of the body, the body tapers towards the caudal fin. There is an obvious spine on upper angle on the margin of the operculum and it has large eyes. The pelvic fins are large, originating und ...

Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...

Pectoral Fins
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Bovichtus
''Bovichtus'' is a genus of fish in the family Bovichtidae found in the Atlantic, Indian and Pacific Ocean. Taxonomy ''Bovichtus'' was formally described as a genus in 1832 by the French zoologist Achille Valenciennes with ''Callionymus diacanthus'', which had been described by the Scottish botanist and officer in the British Army Dugald Carmichael in 1819 with the type locality given as Tristan da Cunha in the South Atlantic, as the type species. The name of the genus, ''Bovichtus'', is derived from bovus meaning "bull" and ''ichthys'' which means fish, based on the local name for ''Bovichtus'' species in Valparaiso, Chile, ''torrito'', meaning "little bull". Species There are currently 8 recognized species in this genus: * '' Bovichtus angustifrons'' Regan, 1913 * '' Bovichtus argentinus'' MacDonagh, 1931 * '' Bovichtus chilensis'' Regan, 1913 * '' Bovichtus diacanthus'' ( Carmichael, 1819) * '' Bovichtus oculus'' Hardy, 1989 * '' Bovichtus psychrolutes'' Günther, 1860 ( ...

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Great Australian Bight
The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia. Extent Two definitions of the extent are in use – one used by the International Hydrographic Organization (IHO) and the other used by the Australian Hydrographic Service (AHS). The IHO defines the Great Australian Bight as having the following limits: ''On the North.'' The south coast of the Australian mainland. ''On the South.'' A line joining West Cape Howe () Australia to South West Cape, Tasmania. ''On the East.'' A line from Cape Otway, Victoria to King Island and thence to Cape Grim, the northwest extreme of Tasmania. The AHS defines the bight with a smaller area, from Cape Pasley, Western Australia, to Cape Carnot, South Australia - a distance of . Much of the bight lies due south of the expansive Nullarbor Plain, which straddles South Australia and Western Australia. The Eyre Highway passes close to the cli ...

Ceduna, South Australia
Ceduna ( ) is a town in South Australia located on the shores of Murat Bay on the west coast of Eyre Peninsula. It lies west of the junction of the Flinders and Eyre Highways around 786 km northwest of the capital Adelaide. The port town/suburb of Thevenard lies 3 km to the west on Cape Thevenard. It is in the District Council of Ceduna, the federal Division of Grey, and the state electoral district of Flinders. The name Ceduna is a corruption of the local Aboriginal Wirangu word ''Chedoona'' and is said to mean a place to sit down and rest. The town has played an important but minor role in Australia's overall development due to it being a fishing port and a railway hub. History Ceduna is on the land of the Wirangu people. Matthew Flinders, on his voyage in the ''Investigator'', anchored in Fowlers Bay on 28 January 1802. He went on to explore the coast and named Denial Bay, Smoky Bay and the islands of Nuyts Archipelago. He was disappointed to find no r ...

Green Cape, New South Wales
Green Cape is a locality situated on the eponymous headland or cape on the far south coast of New South Wales. It is located at 37° 15' S 150° 03' E, within Beowa National Park, south of Eden, New South Wales. The headland forms the northern boundary of Disaster Bay. History The first vessel recorded shipwrecked at Green Cape was the ''City of Sydney'' which struck the cape in fog on 6 October 1862 with more than 100 passengers on board. All passengers and crew boarded lifeboats and made it safely ashore. The Green Cape Lighthouse, the southernmost lighthouse in New South Wales, completed in 1883, was mostly constructed by Albert Aspinall, who constructed a wooden tramway from the nearest landfall at Bittangabee Bay for the purpose. On 31 May 1886 The SS Ly-Ee-Moon en route to Sydney from Melbourne, struck a reef close to the cape at night. 71 souls were lost with the lighthouse keepers only being able to save 15 people under the conditions. Climate Green Cape has an oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Length
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.

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
