Illex Coindetii
''Illex coindetii'', commonly known as the southern shortfin squid or broadtail shortfin squid, is a species of neritic squids in the family Ommastrephidae. They are found in the Mediterranean Sea and on both sides of the north Atlantic Ocean. Description Mature specimens of ''Illex coindetii'' from different populations can vary significantly in both size and form. They are sexually dimorphic, with females being typically larger than males. The maximum recorded mantle length is in males and in females. These unusually large specimens, however, are not typical of the species. The average mantle length is between in males and in females. The eight arms bear two rows of suckers with teeth. In males, the longest of the arms is about 55 to 90% of the total mantle length, while it is 48 to 57% in females. The tentacles have eight longitudinal rows of suckers on the dactylus of the tentacular clubs. The largest middle suckers on the tip are also notched on the rim farthest from t ...

Illex Illecebrosus
''Illex illecebrosus'', commonly known as the northern shortfin squid, is a species of Neritic zone, neritic squids in the Family (biology), family Ommastrephidae. Squids of the genus Illex account for 65% of the world’s cephalopod captures. Illex is formed by four taxa distributed throughout the Atlantic Ocean (I. argentinus, I. coindetii, I. illecebrosus and I. oxygonius), whose identification and phylogenetic relationships based on morphological characters remain controversial.They are found in the northwest Atlantic Ocean, from off the coast of eastern North America to Greenland, Iceland, and west of Ireland and the United Kingdom. They are a highly migratory and short-lived species, with lifespans of less than a year. They are commercially important and are fished extensively (primarily by the United States and Canada), mostly for the Canadian and Japanese markets. Northern shortfin squid is a migratory species of squid with a distribution ranging from Florida Straits to New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japetus Steenstrup
Johannes Japetus Smith Steenstrup FRS(For) HFRSE (8 March 1813 – 20 June 1897) was a Danish zoologist, biologist, and professor. Life Born in Vang, Thy on 8 March 1813, he held a lectorate in mineralogy in Sorø until 1845 when he became a professor of zoology at the University of Copenhagen. He worked on a great many subjects, including cephalopods, and also in genetics, where he discovered the principle of the alternation of generations in some parasitic worms in 1842. Steenstrup discovered (1842) the possibility of using the subfossils of the Postglacial as a means of interpreting climate changes and correlated vegetation change, which he called succession in the recent past. Two of Steenstrup's students, Christian Vaupell and Eugen Warming further developed this line of research. Japetus Steenstrup was a professor to zoologist Johan Erik Vesti Boas, who was also a student of zoologist Carl Gegenbaur, and Hans Christian Gram, inventor of the Gram stain. "Biogra ...

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French Natural history, naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle (''Apalone spinifera''), smooth softshell turtle (''Apalone mutica, A. mutica''), and common map turtle (''Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet bat ...

Ilex
''Ilex'' (), or holly, is a genus of over 570 species of flowering plants in the family (biology), family Aquifoliaceae, and the only living genus in that family. ''Ilex'' has the most species of any woody dioecious angiosperm genus. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide. The type species is ''Ilex aquifolium'', the common European holly used in Christmas decorations and cards. Description The genus ''Ilex'' is divided into three subgenera: *''Ilex'' subg. ''Byronia'', with the type species ''Ilex polypyrena'' *''Ilex'' subg. ''Prinos'', with 12 species *''Ilex'' subg. ''Ilex'', with the rest of the species The genus is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ommastrephidae
Ommastrephidae is a family of squid containing three subfamilies, 11 genera, and over 20 species. They are widely distributed globally and are extensively fished for food. One species, ''Todarodes pacificus'', comprises around half of the world's cephalopod catch annually. Some members of Ommastrephidae ( volplaning species) are known to have the ability to glide out of water, earning them the common name of "flying squid".

''Illex argentinus'', commonly known as the Argentine shortfin squid is a species of 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 t ... in the family Ommastrephidae from the south western Atlantic Ocean. It is one of the most commercially fished species of squid, with 511,087 tons harvested in 2002, or 23.3% of the entire squid harvest. ''Illex argentines'' is most prevalent along the coasts of South America, in Brazil and Argentina. They are some of the most sought after squid species, as some of the largest fisheries in the world are along these coasts, capturing millions of pounds of these shortfin squid a year. Although they are relatively small species, they tend to form dense communities, making them easy to be caught by fisheries by the ton.Chiu Tsan-Yu, Chiu Tai-She ...

Illex Oxygonius
''Illex oxygonius'', commonly known as the sharptail shortfin squid, is a species of neritic squids in the family Ommastrephidae. Of the species of the genus ''Illex'', they have the most restricted range, being found only in the western North Atlantic Ocean; from off New Jersey, south to the Straits of Florida and into the Gulf of Mexico. They are very difficult to distinguish from ''Illex coindetii'' and ''Illex illecebrosus ''Illex illecebrosus'', commonly known as the northern shortfin squid, is a species of Neritic zone, neritic squids in the Family (biology), family Ommastrephidae.

The most obvious difference of ''I. oxygnius'' is their sharper fin angles of 25° to 40° (hence their common name). There is also the possibility that they may be a hybrid of ''I. coindetii'' and ''I. illecebrosus''.Michael Vecchione, Clyde F.E. Roper, & Michael ...
