Loligo Applegatei
''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 ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anoxic Waters
Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen. The US Geological Survey defines anoxic groundwater as those with dissolved oxygen concentration of less than 0.5 milligrams per litre. Anoxic waters can be contrasted with hypoxic waters, which are low (but not lacking) in dissolved oxygen. Often, hypoxia is defined as waters that have less than 2 milligrams per litre of dissolved oxygen. This condition is generally found in areas that have restricted water exchange. In most cases, oxygen is prevented from reaching the deeper levels by a physical barrier, as well as by a pronounced density stratification, in which, for instance, denser, colder or hypersaline waters rest at the bottom of a basin. Anoxic conditions will occur if the rate of oxidation of organic matter by bacteria is greater than the supply of dissolved oxygen. Anoxic waters are a natural phenomenon, and have occurred throughout geological history. The Permia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Taxonomy
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field ...

Squid As Food
Squid is eaten in many cuisines; in English, the culinary name calamari is often used for squid dishes.''Oxford English Dictionary'', 3rd edition, 2002''s.v.''/ref> There are many ways to prepare and cook squid. Fried squid is common Mediterranean cuisine, in the Mediterranean. In New Zealand, Australia, the United States, Canada, and South Africa, it is sold in fish and chips, fish and chip shops and in steakhouses. In Britain, it can be found in Mediterranean "calamari" or Asian "salt and pepper fried squid" forms in various establishments, often served as a bar snack, street food, or starter. Squid can be prepared for consumption in a number of other ways. In Korea and Japan, it is sometimes served raw, and elsewhere it is used as sushi, sashimi and tempura items, grilled, stuffed, covered in batter, stewed in gravy and served in stir-fries, rice, and noodle dishes. Dried shredded squid is a common snack in some Asian regions, including East Asia. Use The body (Mantle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Fishing
Commercial fishing is the activity of catching fish and other seafood for Commerce, commercial Profit (economics), profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is called industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for Fisheries management, fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissection
Dissection (from Latin ' "to cut to pieces"; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine. Consequently, dissection is typically conducted in a morgue or in an anatomy lab. Dissection has been used for centuries to explore anatomy. Objections to the use of cadavers have led to the use of alternatives including virtual dissection of computational anatomy, computer models. In the ...

Photophore
A photophore is a specialized anatomical structure found in a variety of organisms that emits light through the process of boluminescence. This light may be produced endogenously by the organism itself (symbiotic) or generated through a mutualistic relationship with bioluminescent bacteria (non-symbiotic), resulting in light production on a glandular organ of animals. Light organs are most commonly found in marine animals, including many species of fish and cephalopods. The organ can be simple, or as complex as the human eye, equipped with lenses, shutters, color filters, and reflectors; unlike an eye, however, it is optimized to produce light, not absorb it. In the context of developmental biology, light organs form through precise genetic regulation and, in some cases, microbial colonization during specific stages of an organism's life cycle. They play a crucial evolutionary role in enabling species to adapt to low-light or dark environments, particularly in the deep sea. ...

Loligo Reynaudii
''Loligo reynaudii'', commonly known as the Cape Hope squid or chokka squid, is a long squid belonging to the family Loliginidae. In South Africa it is known as either ''calamari'' or ''chokka''. It was previously treated as a subspecies of ''Loligo vulgaris'', the European squid. Description Loligo reynaudii is a marine cephalopod characterized by its elongated slender body, eight short arms, and two long retractile tentacles adorned with suckers. With diamond-shaped fins spanning over half the length of its up to 40 cm (16 in) mantle, this species exhibits distinctive features. Its eyes are covered by a membrane integrated into the head's skin. Notably, the left ventral arm serves as a storage and transfer site for spermatophores, featuring modified distal parts with rows of 44 to 68 tiny outgrowths. Its expanded limbs display transverse rows of suckers, with an enlarged median segment and smooth horny rings. The mantle length measures around 78 mm. Along with reddish-brown p ...

Tree Of Life Web Project
The Tree of Life Web Project (ToL) is an Internet project providing information about the diversity and phylogeny of life on Earth. This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The site has not been updated since 2011, however the pages are still accessible. The pages are linked hierarchically, in the form of the branching evolutionary tree of life, organized cladistically. Each page contains information about one particular group of organisms and is organized according to a branched tree-like form, thus showing hypothetical relationships between different groups of organisms. In 2009 the project ran into funding problems from the University of Arizona. Pages and Treehouses submitted took a considerably longer time to be approved as they were being reviewed by a small group of volunteers, and apparently, around 2011, all activities ended. History The idea of this project started in the late 1980s. David Maddison ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
