Alloteuthis
''Alloteuthis'' is a genus of squids from the pencil squid family Loliginidae which has been considered a subgenus of the genus ''Loligo'' but both molecular analyses and morphological-anatomical analyses support the separation of these two taxa. Species ''Alloteuthis'' as currently recognised comprises three species: *'' Alloteuthis africana'' Adam, 1950, African squid *''Alloteuthis media'' (Linnaeus, 1758), middlesize squid *''Alloteuthis subulata'' (Lamarck Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier.

Alloteuthis Media
''Alloteuthis media'', the midsize squid or little squid, is a species of squid in the family Loliginidae from the eastern Atlantic and the Mediterranean Sea. It is generally a by-catch species in trawl fisheries, although there is an active fishery in the western Mediterranean. Description ''Alloteuthis media'' is hard to tell apart from ''Alloteuthis subulata''. The arms and tentacles of ''A. media'' are proportionately slender compared to ''A. subulata'' but the two species are best separated by the lateral edge of the mantle, which in ''A. media'' extends into a short pointed tail of up to 10mm in length in adults. It grows to a total body length of 200 mm long, with a maximum mantle length of 120mm and the females being larger than the males, with the length of the heart-shaped fins, including the tail, is less than a half the length of the mantle. The hear shape of the fins is produced by their convex anterior ends and then their narrowing posterior edges which become ...

Alloteuthis Subulata
''Alloteuthis subulata'', the European common squid, is a species of squid in the family Loliginidae. Distribution ''Alloteuthis subulata'' is found in the eastern Atlantic Ocean as far south as North-west Africa, the North Sea, the western Baltic Sea, and Mediterranean Sea. In British waters, it has a southernly bias to its distribution but has been found as far north as the Solway Firth and the Firth of Clyde. Description ''Alloteuthis subulata'' has a long, narrow mantle with a long tail which is pointed in adult females and even longer and rather spike-like in adult males. The fins are rhomboid-shaped, with pointed sides, and their rear ends are concave and extend along the tail. The short tentacles are delicate, with small, narrow clubs. Its color is normally pale grey with many brown or purplish spots. Length is up to 21 cm and the maximum mantle length is 14 cm. Habitat ''Alloteuthis subulata'' is usually associated with the water column above sandy and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloteuthis Africana
''Alloteuthis africana'', also known as the African squid, is a species of squid in the family Loliginidae Loliginidae, commonly known as pencil squids, is an aquatic family of squid classified in the order Myopsida. Taxonomy The family Loliginidae was formerly classified in the order Teuthida. Taxonomic list The classification below follows V .... This species of squid is restricted to the Guinean province (from southern Morocco to southern Angola). To identify the ''Alloteuthis africana'' from other ''Alloteuthis'' congeners, it is highly recommended to measure the width of the squids head and the sucker size. References * Vecchione, M., E.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Grimpe
Johann Georg Grimpe (16 February 1889, in Leipzig – 22 January 1936) was a German zoologist and malacologist. He studied zoology and comparative anatomy at the University of Leipzig, where under the influence of Carl Chun (1852–1914), he focused his energies towards research of marine fauna, especially cuttlefish. He conducted studies at marine biology stations in Naples, Villefranche-sur-Mer, Helgoland and Monaco. In 1912 he obtained his doctorate with a dissertation on the vascular system of Octopoda.Grimpe, Johann Georg @ NDB/ADB Deutsche Biographie After graduation, he worked as an assistant at the , being tasked with scientific design issues concerning its |
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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Loligo
''Loligo'' is a genus of squid and one of the most representative and widely distributed groups of myopsid squid. The genus was first described by Jean Baptiste Lamarck in 1798. However, the name had been used earlier than Lamarck ( Schneider, 1784; Linnaeus, 1758) and might even have been used by Pliny. In the early 19th century, this generic name was often used as a grouping for all true squid. All three species of ''Loligo'' are caught by commercial fisheries, most abundantly by traditional trawling methods (mobile gear). In the United States of America, Longfin squid are federally regulated under the Atlantic Mackerel, Squid, and Butterfish Management Plan. ''Loligo vulgaris'' and others are noted for being attracted to lights at night; they can therefore be fished using different light-attraction methods. Commercial fishing is heavily regulated in the United States, and fishing using mobile gear is only permitted during daylight hours. However, the recreational fisherman ...
