Idioteuthis Latipinna
''Idioteuthis latipinna'' is a species of whip-lash squid. It is the type species of the genus ''Idioteuthis''. Richard E. Young and Michael Vecchione consider ''I. latipinna'' to be a junior synonym of '' I. cordiformis'' and the World Register of Marine Species states that it is a taxon inquirendum In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term t ....

Whip-lash Squid
The Mastigoteuthidae, also known as whip-lash squid, are a family of small deep-sea squid. Approximately 20 known species in six genera are represented, with members found in both the mesopelagic and bathypelagic zone of most oceans. Originally described by Verill in 1881, it was later lowered by Chun (1920) to a subfamily (Mastigoteuthinae) of the Chiroteuthidae. However, Roper et al. (1969) raised it back to the family level, and this has not been changed since. The taxonomy of this family is extremely unstable, and there have been at times one genus (Young, Lindgren, & Vecchione, 2008), two genera and four subgenera(Salcedo-Vargas & Okutani, 1994), two genera and several 'groups' (Salcedo-Vargas, 1997), five genera (Braid, McBride, & Bolstad, 2014) and one species with an uncertain placement, or six genera (Young, Vecchione, & Braid, 2014). Description Mastigoteuthids range in size from quite small species in the genus '' Mastigoteuthis'', to relatively gigantic sizes in ...

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 ...

Idioteuthis
''Idioteuthis'' is a genus of whip-lash squid containing at least one species. Some teuthologists consider it synonymous with '' Mastigoteuthis'', but genetics have confirmed the placement of this genus as distinct from all other genera in this family. The placement of ''Idioteuthis'' within the Mastigoteuthidae remains uncertain.

Junior Synonym
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 lev ...

Idioteuthis Cordiformis
''Idioteuthis cordiformis'' is a species of whip-lash squid found in tropical regions of the west Pacific Ocean. The species is commonly known as the 'love-heart squid' because the species name ''cordiformis'' is Latin for 'heart shaped'. Recently, this species has been found to consume small birdbeak dogfish. Description ''Idioteuthis cordiformis'' is a large, deep-sea species that attains a mantle length (body length) of over one meter in length.Braid, 2013 Although multiple specimens have been carefully observed, they are often damaged during capture. Therefore, different authorities have described variations in the colouration of this species: pale flesh-pink, yellowish with small reddish-brown chromatophores, dark purple pigmentation with purple chromatophores overlaid with greyish tubercles, or having thickly crowded deep brownish chromatophores. In life, these animals appear dark red or purple Like all squids, it has eight arms. Like other species in this family, it also h ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Taxon Inquirendum
In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term taxon inquirendum is broader in meaning and refers to an incompletely defined taxon of which the taxonomic validity is uncertain or disputed by different experts or is impossible to identify the taxon. Further characterization is required. See also * Glossary of scientific naming * ''Candidatus'', a proposed taxa based on incomplete evidence * ''incertae sedis'', a taxon of uncertain position in a classification * '' nomen dubium'', a name of unknown or doubtful application * Open nomenclature Open nomenclature is a vocabulary of partly informal terms and signs in which a taxonomist may express remarks about their own material. This is in contrast to synonymy lists, in which a taxonomist may express remarks on the work of others. Common . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
