Taningia Danae7
''Taningia'' is a genus of squid in the family Octopoteuthidae. For over 150 years, it has been believed to comprise a single species known as ''Taningia danae.'' Recently it has been shown to contain at least two new species (''Taningia fimbria, T. fimbria'', ''T. rubea''). Another species, ''Taningia persica'', has historically been referred to but has been questioned. This genus is named after Danish people, Danish fishery, fisheries biologist Åge Vedel Tåning (1890-1958).

Louis Joubin
Louis Marie Adolphe Olivier Édouard Joubin (27 February 1861 in Épinal – 24 April 1935 in Paris) was a professor at the Muséum national d'Histoire naturelle in Paris. He published works on nemerteans, chaetognatha, cephalopods, and other molluscs. He served as an assistant to Henri de Lacaze-Duthiers, subsequently becoming director of the laboratories at Banyuls-sur-Mer (1882) and Roscoff (1884). Later on, he became an instructor at the University of Rennes,Prosopo Sociétés savantes and in 1903 succeeded Edmond Perrier as ''chaire des mollusques, des vers et des zoophytes'' at the |
Flanders Marine Institute
The Flanders Marine Institute (Dutch: Vlaams Instituut voor de Zee, VLIZ) provides a focal point for marine scientific research in Flanders, northern Belgium. The Flemish government established the institute in 1999 together with the province of West Flanders and the Fund for Scientific Research. VLIZ promotes the accumulation of knowledge and excellence in research with regard to the ocean, seas, coasts and tidal estuaries. The central focus is on the provision of services to the research community, educators, the general public, policymakers and the industry. VLIZ promotes and supports Flemish marine research. Within this scope, VLIZ focuses on open, useful networking and the promotion of an integrated and cross-disciplinary approach. VLIZ serves as a national and international point of contact in the field of marine research. In this respect, it supports the image of Flemish marine research in the four corners of the globe and can hold mandates to represent this research landsc ...

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 ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Octopoteuthidae
The Octopoteuthidae are a family of squid comprising two genera. The family is characterized by tentacles which cease to grow after the paralarval stage, and the use of a penis, instead of a hectocotylus A hectocotylus (plural: ''hectocotyli'') is one of the arms of male cephalopods that is specialized to store and transfer spermatophores to the female. Structurally, hectocotyli are muscular hydrostats. Depending on the species, the male may use i ....

Taningia Fimbria
''Taningia fimbria'' is a recently described species of octopoteuthid squid from the genus ''Taningia'.'' Like its better-known congener '' T. danae'', ''T. fimbria'' is capable of achieving large sizes as adults; a recently examined specimen exceeded 1.65 m in mantle length. Like other members of the genus, ''T. fimbria'' lacks tentacles beyond small paralarval stages, has arms bearing two rows of sheathed hooks (instead of suckers), and bears large photophores at the tips of two arms. However, several unique characteristics separate the species from other species of ''Taningia''. These include: * lanceolate projections extending from the inner funnel aperture (unique character among known cephalopods) * epidermal tubercles (a unique feature in the genus and family) * modifications to arm hooks and arm morphology See also * Giant squid * Giant squid in popular culture The giant squid's elusive nature and fearsome appearance have long made it a popular subject of legends and f ...

Danish People
Danes ( da, danskere, ) are a North Germanic ethnic group and nationality native to Denmark and a modern nation identified with the country of Denmark. This connection may be ancestral, legal, historical, or cultural. Danes generally regard themselves as a nationality and reserve the word "ethnic" for the description of recent immigrants, sometimes referred to as "new Danes". The contemporary Danish national identity is based on the idea of "Danishness", which is founded on principles formed through historical cultural connections and is typically not based on racial heritage. History Early history Denmark has been inhabited by various Germanic peoples since ancient times, including the Angles, Cimbri, Jutes, Herules, Teutones and others. The first mentions of " Danes" are recorded in the mid-6th century by historians Procopius ( el, δάνοι) and Jordanes (''danī''), who both refer to a tribe related to the Suetidi inhabiting the peninsula of Jutland, the province of Sc ...

Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life; or more commonly, the site where such enterprise takes place ( a.k.a. fishing ground). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem — causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served " approach, but recent threats by human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.
