Bludger (fish)
The bludger (''Carangoides gymnostethus''), also known as the bludger trevally, nakedbreast trevally or Bleeker's jackfish, is a widespread species of large marine fish in the jack family, Carangidae. The bludger inhabits the tropical and subtropical regions of the Indo-west Pacific Ocean, distributed from South Africa in the west to Japan and New Caledonia in the east. It is a large fish, growing to a maximum recorded length of 90 cm, and is very similar to the yellowspotted trevally, ''Carangoides fulvoguttatus'', but can be separated by the complete absence of breast scales and a number of other anatomical features. The species inhabits moderately deep offshore coral and rocky reefs, where it preys on small crustaceans and fish. The reproductive biology of the species is poorly known, but it appears to move to more tropical waters to spawn. The bludger is of intermediate importance to fisheries throughout its range, taken by hook and line and various netting methods. It ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...

Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Classification
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carangiformes
Carangiformes is an order of the ray-finned fishes. The order is part of a clade which is a sister clade to the Ovalentaria, the other orders in the clade being Synbranchiformes, Anabantiformes, Istiophoriformes and Pleuronectiformes. The Carangiformes has been regarded as a monotypic order, with only the Carangidae within it, by some authorities and the families within the order have been classified as part of the wider order Perciformes. The 5th edition of Fishes of the World classify six families within the order Carangiformes, with other authorities expanding the order to include up to 30 families. Families The following families are classified within the order Carangiformes: * Nematistiidae Gill (roosterfish) * Coryphaenidae Rafinesque, 1815 (dolphinfish) * Rachycentridae Gill 1896 (cobia) * Echeneidae Rafinesque, 1815 (remoras) * Carangidae Rafinesque, 1815 (jacks) * Menidae The moonfish of the genus ''Mene'', the sole extant genus of the family Menidae, are disk-sha ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Carangoides
''Carangoides'' is a genus of tropical to subtropical marine fishes in the jack family, Carangidae. They are small- to large-sized, deep-bodied fish characterised by a certain gill raker and jaw morphology, often appearing very similar to jacks in the genus ''Caranx''. They inhabit the subtropical and tropical regions of the Indian, Pacific, and Atlantic Oceans, often occupying coastal areas, including reefs, bays, and estuaries, rarely venturing far offshore. They are all predatory fishes, taking a variety of smaller fishes, crustaceans and cephalopods as prey. The genus was first erected in 1851 by Pieter Bleeker for an unknown taxon and currently contains 20 species. Many make up significant proportions of various fisheries, although a number of ciguatera cases have been attributed to them. Taxonomy The genus ''Carangoides'' is one of 31 genera in the jack and horse mackerel family, the Carangidae are part of the order Carangiformes. A number of recent phylogenetic studies ...

Gamefish
Game fish, sport fish or quarry refer to popular fish pursued by recreational anglers, and can be freshwater or saltwater fish. Game fish can be eaten after being caught, or released after capture. Some game fish are also targeted commercially, particularly salmon and tuna. Specimens of game fish whose measurements (body length and weight) are a lot above the species' average are sometimes known as trophy fish. Examples The species of fish prized by anglers varies with geography and tradition. Some fish are sought for their value as food, while others are pursued for their fighting abilities, or for the difficulty of successfully enticing the fish to bite the hook. * Big-game fish are blue water saltwater bony fish such as tuna, tarpon, grouper and billfish (sailfish, marlin and swordfish). Occasionally other predatory fishes such as sharks, barracuda and dolphinfish are also pursued. * In North America, many anglers fish for common snook, redfish, salmon/trout, bass, nor ...

Angling
Angling is a fishing technique that uses a fish hook or "angle" (from Old English ''angol'') attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. When ...
