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.

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 ...

Heterololigo Bleekeri
''Heterololigo'' is a monotypic genus of squids containing the single species ''Heterololigo bleekeri''. It was formerly classified in the genus '' Loligo''; some authors still include it there, but DNA evidence supports its separation into a genus of its own. This species is known by the common name spear squid. This squid is native to the western Pacific Ocean along the coast of Asia. It can be distinguished from other species in its family by its shorter tentacles. It spawns in spring and summer in the northern part of its range, and in winter farther south. It has a life span of about one year. They are pelagic, found from around 0 - 100 meters. This squid is caught for food off the coast of Japan. It lays its eggs on the underside of submerged objects. In order to increase catches, artificial substrates have been installed along the coast of Japan to provide more egg-laying sites. This species is important in biological research. Its mitochondrial genome has been sequenced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Doryteuthis Plei
''Doryteuthis plei'', also known as the slender inshore squid or arrow squid, is a medium-sized squid belonging to the family Loliginidae. It occurs abundantly in coastal waters of the Atlantic Ocean, from Argentina northward to North Carolina. Description As both common names imply, these squid have elongate, cylindrical bodies with a length to width ratio of 7:1. The arms are in contrast short and weak; the two tentacles are somewhat less than the mantle length. The rhombus-shaped fins are large, up to about 50 percent of the mantle length. Running the ventral length of the mantle is a noticeable ridge. The squid are a reddish orange colour with a large complement of chromatophores. The suckers of the arms possess blunt teeth. On the meaty ends (''clubs'') of the tentacles, there are four rows of suckers; the inner two (''mesial'') rows are three times as large as the outer two (''marginal'') rows. The larger suckers have horny rings with up to 45 teeth. These squid reach a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doryteuthis Pealeii
The longfin inshore squid (''Doryteuthis pealeii'') is a species of squid of the family Loliginidae. Description This species of squid is often seen with a reddish hue, but like many types of squid can manipulate its color, varying from a deep red to a soft pink. The dorsal mantle length of some males can reach up to 50 cm, although most squid commercially harvested are smaller than 30 cm long. This species exhibits sexual dimorphism, with most males growing faster and reaching larger sizes than females. Distribution The longfin inshore squid is found in the North Atlantic, schooling in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela. It is commercially exploited, especially in the range from the Southern Georges Bank to Cape Hatteras. The population makes seasonal migrations that appear to be related to bottom water temperatures; they move offshore during late autumn to overwinter along the edge of the continental shelf and return insh ...

Doryteuthis Opalescens
''Doryteuthis opalescens'', the opalescent inshore squid or market squid, is a small squid ( mantle length (ML) up to 190 mm) in the family Loliginidae. It is a myopsid squid, which is the near shore group and that means that they have corneas over their eyes. The species lives in the eastern Pacific Ocean from Mexico's Baja California peninsula to Alaska, United States, and as an inshore squid it can be found with a range of off the coast. Description Adult ''Doryteuthis opalescens'' can reach a total size of 11 inches. Males are typically larger with a mantle length of 5 – 3 1/2 inches , while females are 5 –7 inches in mantle length.Morris, Robert H., Donald P. Abbott, Eugene R. Haderlie. 1980. ''Intertidal Invertebrates of California''. Stanford: Stanford University Press. The mantle of ''D. opalescens'' is not fused to the head and its body is 4 to 5 times longer than it is wide, with fins equal in both length and width. This squid has 8 arms with 2 longer te ...

European Squid
The European squid or common squid (''Loligo vulgaris'') is a large squid belonging to the family Loliginidae. It occurs abundantly in coastal waters from the North Sea to at least the west coast of Africa. This species lives from sea level to depths of . Its mantle is up to long. The species is extensively exploited by commercial fisheries. ''Loligo reynaudii'', the Cape Hope squid, was previously treated as a subspecies of ''L. vulgaris''. Description The European squid has a long, moderately slender and cylindrical body. Rhomboid fins comprise two-thirds of the mantle length, though locomotion is via jet propulsion. The posterior border is slightly concave. The head is relatively small and has large eyes which are covered with a transparent membrane. Like almost all squid, this species has ten limbs surrounding the mouth and beak: eight are relatively short arms, and two, which form the tentacles, are long, as they are used to catch prey. The fourth left arm o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lolliguncula Brevis
''Lolliguncula brevis'', or the Atlantic brief squid, is a small species of squid in the Loliginidae family. It is found in shallow parts of the western Atlantic Ocean. Distribution The Atlantic brief squid occurs most frequently in shallow waters along the eastern seaboard of the United States as far north as Delaware. It has also been found in Argentina, Brazil, the British Virgin Islands, Colombia, Mexico, Panama, Puerto Rico, Suriname, Trinidad and Tobago and Venezuela. Description image:Lolliguncula brevis1.jpg, left, ''Lolliguncula brevis'' The female Atlantic brief squid is about 11 cm long and the male 9 cm. The basic colour is dark reddish-brown to yellow-brown and there are many chromatophores on the upper surface which enable the squid to change colour. The Mantle (mollusc), mantle is widest in the middle and tapers to a rounded point at the back. The fins are wider than they are long, rounded and about half the length of the mantle. The mantle has thick musc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doryteuthis Ocula
''Doryteuthis'' is a genus of squid from the waters of the western Atlantic and eastern Pacific off the coast of the Americas species are the common inshore squids of American waters. Some species are important quarry species for fisheries. In ''Doryteuthis'' the tentacular clubs are expanded and bear suckers in 4 series. The hectocotylus is on the left ventral arm IV with unmodified suckers near the base, lack of a ventral crest while the reduced on elongated stalks form papillae on the dorsal series or on both dorsal and ventral series. The fins are situated in a posterior position. The spermatophore has a short, cement body cement body and they do not have any photophores. Taxonomy ''Doryteuthis'' is divided into two subgenera, ''Amerigo'' and ''Doryteuthis''.

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 ...
