Pataecidae
The Australian prowfishes are a small family, the Pataecidae, of ray-finned fishes classified within the order Scorpaeniformes. Australian prowfishes are distinguished by a long dorsal fin that begins far forward on the head, forming a "prow" shape, and extends all the way to the caudal fin. They lack scales and pelvic fins. Taxonomy The Australian prowfishes were first recognised as a family in 1872 by the American biologist Theodore Gill with the type species of the family being '' Pataecus fronto'' which had been described by John Richardson in 1844. The 5th edition of ''Fishes of the World'' classifies the family within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. A recent study placed this family into an expanded stonefish clade, Synanceiidae, because all of these fish have a lachrymal sabre that can project a switch-blade-like mechanism out from underneath thei ...

Neopataecus Waterhousii
The whiskered prowfish (''Neopataecus waterhousii'') is a species of marine ray-finned fish, an Australian prowfish belonging to the family Pataecidae. It is endemic to the coastal waters of southern Australia. This species is the only member of the monotypic genus ''Neopataecus''. Taxonomy The whiskered prowfish was first formally described in 1872 as''Pataecus waterhousii'' by the French naturalist Francis de Laporte de Castelnau with the type locality given as the St Vincent Gulf in South Australia. In 1884 Franz Steindachner described a new subgenus of '' Aetapcus'', ''Neopataecus'', for this species and this is now considered to be a valid genus.The 5th edition of ''Fishes of the World'' classifies the family Pataecidae, in which this genus is classified, within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. A recent study placed the Australian prowfishes into an ...

Aetapcus
The warty prowfish (''Aetapcus maculatus''), also known as the smooth prowfish or Tasmanian prowfish, is a species of marine ray-finned fish, an Australian prowfish belonging to the family Pataecidae, It is endemic to the coastal waters of southern Australia where it inhabits mostly rocky reefs. This species is the only member of the monotypic genus ''Aetapcus''. Taxonomy The warty prowfish was first formally described in 1861 as ''Pataecus maculatus'' by the German-born British ichthyologist Albert Günther with the type locality given as Fremantle in Western Australia. In 1936 the Australian teacher and ichthyologist Eric Oswald Gale Scott classified this species within the monotypic genus ''Aetapcus''. The 5th edition of ''Fishes of the World'' classifies the family Pataecidae within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. A recent study placed the Australian p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaenoidei
Scorpaenoidei is a suborder of ray-finned fishes, part of the order Scorpaeniformes, that includes the scorpionfishes, lionfishes and velvetfishes. This suborder is at its most diverse in the Pacific and Indian Oceans but is also found in the Atlantic Ocean. Taxonomy Scorpaenoidei was first named as a suborder in 1899 by the American ichthyologist Samuel Garman as a suborder of the Perciformes. Some authorities still treat the suborder as being part of the Perciformes but the 5th Edition of ''Fishes of the World'' recognises the Scorpaeniformes as a valid order and places this suborder within it. The subfamilies of the family Scorpaenidae are treated as families by some authors. It has been argued by some authors that the suborder is paraphyletic and that a more correct classification is that the grouping, with some differences, be placed on the superfamily Scorpaenoidea. Families and subfamilies The suborder Scorpaenoidei is classified into families and subfamilies in the 5th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaeniformes
The Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the pre operculum, to which it is connected in most species. Scorpaeniform fishes are carnivorous, mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral and caudal fins. Most species are less than in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactin ...

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

Joseph S
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled '' Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and k ...

Anal Fin
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 ...

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.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Prow
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ve ...

Figurehead (object)
A figurehead is a carved wooden decoration found at the bow of ships, generally of a design related to the name or role of a ship. They were predominant between the 16th and 20th centuries, and modern ships' badges fulfill a similar role. History Although earlier ships had often had some form of bow ornamentation (e.g. the eyes painted on the bows of Greek and Phoenician galleys, the Roman practice of putting carvings of their deities on the bows of their galleys, and the Viking ships of ca. A.D. 800–1100), the general practice was introduced with the galleons of the 16th century, as the figurehead as such could not come to be until ships had an actual stemhead structure on which to place it. The menacing appearance of toothy and bug-eyed figureheads on Viking ships were considered a form of apotropaic magic, serving the function of warding off evil spirits. The Egyptians placed figures of holy birds on the prow while the Phoenicians used horses representing speed. The Ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
