Oceanic Whitetip Shark
The oceanic whitetip shark (''Carcharhinus longimanus'') is a large requiem shark inhabiting the pelagic zone of tropical and warm temperate seas. It has a stocky body with its iconic elongated rounded fins, with white tips. The species is typically solitary, though they may gather in large numbers at food concentrations. Bony fish and cephalopods are the main components of its diet and females give live birth. Though slow-moving, the shark is opportunistic and aggressive, and is reputed to be dangerous to shipwreck survivors. The IUCN Red List considers the species to be critically endangered. As with other shark species, the whitetip faces mounting fishing pressure throughout its range, with recent studies show steeply declining populations as they are harvested for their fins and meat. Taxonomy The oceanic whitetip shark is known by many other english common names: Brown Milbert's sand bar shark, brown shark, shipwreck shark, nigano shark, oceanic white-tipped whale ...

Pilot Fish
The pilot fish (''Naucrates ductor'') is a carnivorous fish of the trevally, or jackfish family, Carangidae. It is widely distributed and lives in warm or tropical open seas. Description The pilot fish congregates around sharks, rays, and sea turtles, where it eats ectoparasites on, and leftovers around, the host species; younger pilot fish are usually associated with jellyfish and drifting seaweeds. They are also known to follow ships, sometimes for long distances; one was found in County Cork, Ireland, and many pilot fish have been sighted on the shores of England. Their fondness for ships led the ancients to believe that they would navigate a ship to its desired course. The pilot fish's colour is between dark blue and blackish-silver, with the belly being lighter in colour.Eschmeyer & Herald 1999, p. 208. The pilot fish is also known to have a temporary variation of colour when excited; its dark-coloured bars disappear, and its body turns silvery-white, with three broad ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Nomen Oblitum
In zoological nomenclature, a ''nomen oblitum'' (plural: ''nomina oblita''; Latin for "forgotten name") is a disused scientific name which has been declared to be obsolete (figuratively "forgotten") in favor of another "protected" name. In its present meaning, the ''nomen oblitum'' came into being with the fourth edition (1999) of the ''International Code of Zoological Nomenclature''. After 1 January 2000, a scientific name may be formally declared to be a ''nomen oblitum'' when it satisfy the following conditions: # No uses as a valid name in a scientific publication are known after 1899 (this criterion is taken on faith). # It is either a senior synonym (there is also a more recent name which applies to the same taxon, and which is in common use) or a senior homonym (it is spelled the same as another name, which is also in valid use). # The preferred junior synonym or homonym is shown to be in wide use, defined as appearing in 25 or more publications in the past 50 years (must ...

International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Shark Meat
Shark meat is a seafood consisting of the flesh of sharks. Several sharks are fished for human consumption, such as porbeagles, shortfin mako shark, requiem shark, and thresher shark, among others. Shark meat is popular in Asia, where it is often consumed Drying (food), dried, Smoking (cooking), smoked, or Salting (food), salted. The largest consumer of shark meat in the World is Brazil, but it is also consumed regularly in Iceland, Japan, Australia, parts of India, parts of Canada, Sri Lanka, areas of Africa, Mexico and Yemen. Sharks have been eaten at least since the Late Bronze Age (1550–1130 BC), for example in the Levant. Preparation Unprocessed shark meat may have a strong odor of ammonia, due to the high urea content that develops as the fish decomposes. The urea content and ammonia odor can be reduced by Marination, marinating the meat in liquids such as lemon juice, vinegar, milk, or saltwater. Preparation methods include slicing the meat into Fish steak, steaks and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shark Finning
Shark finning is the act of removing fins from sharks and discarding the rest of the shark back into the ocean. This act is prohibited in many countries. The sharks are often still alive when discarded, but without their fins.Spiegel, J. (2000"Even Jaws deserves to keep his fins: outlawing shark finning throughout global waters" ''Boston College International and Comparative Law Review'', 24 (2): 409–438. Unable to swim effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea enables fishing vessels to increase profitability and increase the number of sharks harvested, as they must only store and transport the fins, by far the most profitable part of the shark; the shark meat is bulky to transport. Many countries have banned this practice and require the whole shark to be brought back to port before removing the fins. Shark finning increased since 1997 largely due to the increasing demand for shark fins f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
