Onychoteuthis Bergii
''Onychoteuthis bergii'' is a species of hooked squid from the family Onychoteuthidae. The species was originally described by Hinrich Lichtenstein from specimens taken near the Cape of Good Hope and is the type species of the genus '' Onychoteuthis''. Until recently it was considered to be a junior synonym of ''Onychoteuthis banksii'', but a re-examination of the type material, the lectotype and paralectotype which are deposited in the Natural History Museum, Berlin The Natural History Museum (german: Museum für Naturkunde) is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major muse ..., showed that there were morphological differences which supported the status of ''O. bergii'' as a valid species. The species is found in the eastern South Atlantic and Indian Oceans. References {{Taxonbar, from=Q13924104 Squid Cephalopods described in 1818< ...

Hinrich Lichtenstein
Martin Hinrich Carl Lichtenstein (10 January 1780 – 2 September 1857) was a German physician, explorer, botanist and zoologist. Biography Born in Hamburg, Lichtenstein was the son of Anton August Heinrich Lichtenstein. He studied medicine at Jena and Helmstedt. Between 1802 and 1806 he travelled in southern Africa, becoming the personal physician of the Governor of the Cape of Good Hope. In 1811 he published ''Reisen im südlichen Afrika : in den Jahren 1803, 1804, 1805, und 1806''; as a result, he was appointed professor of zoology at the University of Berlin in 1811, and appointed director of the Berlin Zoological Museum in 1813. In 1829, he was elected a foreign member of the Royal Swedish Academy of Sciences. He died after he had a stroke at sea travelling aboard a steamer from Korsør to Kiel. Legacy Lichtenstein was responsible for the creation of Berlin's Zoological Gardens in 1841, when he persuaded King Frederick William IV of Prussia to donate the grounds of ...

Hooked Squid
The hooked squid, family Onychoteuthidae, currently comprise about 20–25 species (several known from only single life stages and thus unconfirmed), in six or seven genera. They range in mature mantle length from 7 cm to a suggested length of 2 m for the largest member, '' Onykia robusta''. The family is characterised by the presence of hooks only on the tentacular clubs, a simple, straight, funnel–mantle locking apparatus, and a 'step' inside the jaw angle of the lower beak. With the exception of the Arctic Ocean, the family is found worldwide.

Cape Of Good Hope
The Cape of Good Hope ( af, Kaap die Goeie Hoop ) ;''Kaap'' in isolation: pt, Cabo da Boa Esperança is a rocky headland on the Atlantic coast of the Cape Peninsula in South Africa. A common misconception is that the Cape of Good Hope is the southern tip of Africa, based on the misbelief that the Cape was the dividing point between the Atlantic and Indian oceans, and have nothing to do with north or south. In fact, by looking at a map, the southernmost point of Africa is Cape Agulhas about to the east-southeast. The currents of the two oceans meet at the point where the warm-water Agulhas current meets the cold-water Benguela current and turns back on itself. That oceanic meeting point fluctuates between Cape Agulhas and Cape Point (about east of the Cape of Good Hope). When following the western side of the African coastline from the equator, however, the Cape of Good Hope marks the point where a ship begins to travel more eastward than southward. Thus, the first mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Onychoteuthis
''Onychoteuthis'' is a genus of squid in the family Onychoteuthidae. The type species is ''Onychoteuthis bergii''. While the genus is found worldwide in tropical and subtropical oceans, they can also occur in the North Pacific Ocean. There were previously considered to be four species in the genus but there are now considered to be roughly 10. These squid are frequently observed in the surface waters at night and they are often caught using dipnet at nightlight stations. The young squid are usually the only specimens captured using standard midwater trawls, the older squid are apparently able to avoid the trawls. They can, however be collected from the air as individuals are able to leap high out of the water, sometimes even landing on the deck of a ship. Anatomy Most species belonging to the genus have a mantle length of under 200 mm, however the larger members may measure over 300 mm. The species in this genus have a densely muscular, cylindrical mantle which is tap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonyms (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia leva ...

Onychoteuthis Banksii
''Onychoteuthis banksii'', the common clubhook squid, is a species of squid in the family Onychoteuthidae. It is the type species of the genus '' Onychoteuthis''. This species was thought to have a worldwide distribution but with the revision of the genus '' Onychoteuthis'' in 2010, it is now accepted that ''Onychoteuthis banksii'' is restricted to the central and northern Atlantic and the Gulf of Mexico while a recently described species, '' Onychoteuthis horstkottei'', is found in the Pacific Ocean. The type locality is the Gulf of Guinea. Description The maximum mantle length is . The eight arms are all of equal size and the tentacles are 27% of the mantle length. The clubs on the end of the tentacles bear two rows of strongly recurved hooks. There are two intestinal photophores, the anterior one being larger than the posterior one; there are also photophores in the form of whitish patches on the underside of the eyeballs. Most squid live in deep water, and in these, the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (zoology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
