Squid Komodo
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 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 jet propulsion, and largely locate their prey by sight. They are among the most intelligent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loligo Forbesii
''Loligo forbesii'' (sometimes erroneouslyBouchet, P. and S. Gofas. (2013)''Loligo forbesi'' Steenstrup, 1856.World Register of Marine Species. Accessed 5 June 2013. spelled ''forbesi''), known commonly as the veined squid and long-finned squid, is a commercially important species of squid in the family Loliginidae, the pencil squids. Description This squid grows up to in mantle length. The long fins are roughly diamond-shaped and make up two thirds of the total length of the body.

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 fisherma ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Africanus
''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 .... 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.

Myopsida
Myopsida is one of the four orders of squid. It consists of two families: the monotypic '' Australiteuthis'' and the diverse and commercially important Loliginidae (~50 species). Some taxonomists classify this taxon as a suborder of the order Teuthida, in which case it is known as Myopsina. This reclassification is due to Myopsina and Oegopsina not being demonstrated to form a clade. A number of morphological features distinguish members of Myopsida from those of its sister group, Oegopsida. Some of the most obvious differences are found in the structure of the eyes: those of myopsid squids lack a secondary eyelid and are instead covered by a transparent corneal membrane, the opening of which is reduced to a microscopic anterior pore in most species. The arms and tentacles are ornamented with simple suckers (hooks are never present), with additional suckers usually borne on the buccal lappets. The carpal ("wrist") portion of the tentacular club lacks a locking apparatus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 in ...

Doryteuthis Gahi
''Doryteuthis gahi'', also known as the Patagonian longfin squid and Patagonian squid (Spanish: ''calamar patagónico''), is a small-sized squid belonging to the family Loliginidae. It occurs in coastal waters in the southeastern Pacific Ocean and the southwestern Atlantic Ocean where it is caught and eaten for food. Description The Patagonian squid is a small species and has a mantle length of and a weight of between . The mantle is somewhat elongated and on either side at the posterior end are rhomboidal fins, rather less than half the length of the mantle. At the anterior end are four pairs of arms and a pair of tentacles. The third and fourth pairs of arms are longer than the others, and in males, the left fourth arm is heterodactylised near its tip. The tentacles are long and slender, each terminated by a club-shaped "manus" with small, narrow suckers at the edge and slightly larger ones at the centre. Distribution This squid occurs in the southeastern Pacific Ocean and ... [...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] |
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.
