Squid Komodo
A squid (: squid) is a mollusc with an elongated soft body, large eyes, eight arms, and two tentacles in the orders Myopsida, Oegopsida, and Bathyteuthida (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 amo ...

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 fishe ...

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 becom ...

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 (includi .... 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 of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loliolus Sumatrensis 2
''Loliolus'' is a genus of squid from the family Loliginidae from the Indo-Pacific region. The genus is divided into two subgenera ''Loliolus'' and ''Nipponololigo''. They are small squids of less than in mantle length which have an expanded tentacular club. This club has 4 series of suckers. The sucker rings have plate-like teeth which are square in shape all around them. The males' hectocotylus has a ventral crest which is created by the fusion of the protective membrane with the ventral series of papillae and this crest completely obscures the conical shape of the papillae. The mantle is rounded posteriorly and lacks the posterior tail-like lobe while the fins are positioned on the rear of the mantle and extend to the posterior tip of the mantle. Their eggs are small and the males' spermatophore has a short cement body. They do not possess photophores. The two subgenera are distinguished by the hectocotylus which in ''Loliolus'' encompasses the entire arm and there are no unmo ...

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 left, ''Lolliguncula brevis'' The female Atlantic brief squid is about 11 cm long and the male 9 cm. The maximum mantle length recorded was 12 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 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 muscul ...

Caribbean Reef Squid
The Caribbean reef squid (''Sepioteuthis sepioidea''), commonly called the reef squid, is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of the body, approximately 20 cm (8 in) in length. They are most commonly found in the Caribbean Sea in small schools. As part of the Cephalopod class of Molluscs, these organisms exhibit specific characteristics to help them in their environment, such as tentacles for movement and feeding and color pigments that reflect their behavioral conditions. History and phylogeny The reef squid is included in the monophyletic family ''Loliginidae,'' which houses a discovered twenty-six species. The origin of the family is the geographical Cretaceous period within the Indo-Pacific sea region. In 2001, marine biologist Silvia Maciá discovered that squid were able to propel themselves up out of the water about 2 m (6.6 ft) and fly approximately 10 m (33 ft) before re-entry; a discovery which led to th ...
