Dana Octopus Squid
''Taningia danae'', the Dana octopus squid, is a species of squid in the family Octopoteuthidae, the octopus squids. It is one of the largest known squid species, and it has one of the largest photophores (light organs) known in any organism, useful in the deep-sea environments that the species inhabits. Discovery The possible (but unconfirmed) first specimen of this species was collected in 1769, when Joseph Banks, member of Captain Cook’s first voyage, spotted a massive "cuttlefish" floating in the South Pacific, off the coast of Chile. Seabirds had already damaged it, and most of the remaining carcass was prepared into a meal which Banks described as "one of the best soups eever ate". However, he made sure to preserve an arm, some entrails, and the buccal mass including the beak, which would eventually enter John Hunter's collection in London; the surviving buccal mass (apparently prepared by John Hunter himself) is still part of the Hunterian Museum’s collection to t ...

Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about .

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] |
Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life or, more commonly, the site where such enterprise takes place ( a.k.a., fishing grounds). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem, causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served" approach, but recent threats from human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Danish People
Danes (, ), or Danish people, are an ethnic group and nationality native to Denmark and a modern nation identified with the country of Denmark. This connection may be ancestral, legal, historical, or cultural. History Early history Denmark has been inhabited by various Germanic peoples since ancient times, including the Angles (tribe), Angles, Cimbri, Jutes, Herules, Teutones and others. A 2025 study in ''Nature'' found genetic evidence of an influx of central European population after about 500 ce into the region later ruled by the Danes. Viking Age The first mention of Danes within Denmark is on the Jelling stones#Runestone of Harald Bluetooth, Jelling Rune Stone, which mentions the conversion of the Danes to Christianity by Harald Bluetooth in the 10th century. Between and the early 980s, Bluetooth established a kingdom in the lands of the Danes, stretching from Jutland to Scania. Around the same time, he received a visit from a German missionary who, by surviving an t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nomina Dubia
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium,'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enoploteuthis
''Enoploteuthis'' is a genus of squid in the family Enoploteuthidae, being the type genus. ''Enoploteuthis'' is a genus with a relatively high number of species, most of which were described in the late 20th and early 21st century. They have been collected during exploratory trawling in the mesopelagic zone. They are an important food source for fishes and toothed whales but they are of little commercial value, except for '' Enoploteuthis chunii'' which is caught as bycatch in the Japanese fishery for '' Watasenia scintillans''. Many species are diel migrants, spending the day at depth and moving up the water column at night to feed. Description The species of ''Enoploteuthis'' are most easily recognised by having a larger "tail" (trailing part of the mantle) when compared to the other genera in the Enoploteuthidae. The tail's size is emphasized by not having the fins extending along its sides. In related genera there is a narrow extension of the fins along the tail. Other char ...

Sepia (cephalopod)
''Sepia'' is a genus of cuttlefish in the family (biology), family Sepiidae encompassing some of the best known and most common species. The cuttlebone is ellipsoid in shape. The name of the genus is the Latinised form of the Ancient Greek (''sēpía'') "cuttlefish". Anatomy All members of ''Sepia'' possess Cephalopod limb, eight arms and two tentacles. Tentacles are retractable limbs used to target and latch onto prey, whereas arms are used for handling prey and producing patterns of light and dark to distract prey. Once a prey item has been caught, the tentacles detach from it and have no other function. The tentacles reside in sheaths that run below the eyes and behind the head, into the visceral mass, where they are reserved as coiled, spring-loaded appendages, waiting to be ejected towards a food target. Classification A 2023 paper extensively revised the composition of genus ''Sepia''; As a consequence, many species have been split out of genus ''Sepia'', assigned to revi ...

Scientific Name
In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammar, Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the ''generic name (biology), generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunterian Museum, London
The Hunterian Museum is a museum of anatomical specimens in London, located in the building of the Royal College of Surgeons of England. History In 1799 the government purchased the collection of the Scottish surgeon John Hunter which they presented to the college. This formed the basis of the Hunterian Collection, which has since been supplemented by others including an Odontological Collection (curated by A. E. W. Miles until the early 1990s) and the natural history collections of Richard Owen. The first museum building was considered inadequate in terms of space, and was closed in April 1834 to allow for an expansion project which added additional East and West galleries, completed in February 1837. A third room was added in 1852, and two further galleries were added between 1888 and 1892. In May 1941 the college building was badly damaged by bombs, with Rooms IV and V of the museum being completely destroyed along with their contents. After a slow process of entirely ne ...

John Hunter (surgeon)
Sir John Hunter (13 February 1728 – 16 October 1793) was a Scottish people, Scottish surgery, surgeon, one of the most distinguished scientists and surgeons of his day. He was an early advocate of careful observation and scientific methods in medicine. He was a teacher of, and collaborator with, Edward Jenner, pioneer of the smallpox vaccine. He paid for the stolen body of Charles Byrne (giant), Charles Byrne, and proceeded to study and exhibit it against the deceased's explicit wishes. His wife, Anne Hunter (), was a poet, some of whose poems were set to music by Joseph Haydn. He learned anatomy by assisting his elder brother William Hunter (anatomist), William with dissections in William's anatomy school in Central London, starting in 1748, and quickly became an expert in anatomy. He spent some years as an Army surgeon, worked with the dentist James Spence conducting tooth transplants, and in 1764 set up his own anatomy school in London. He built up a collection of living ...

Cephalopod Beak
All extant taxon, extant cephalopods have a two-part beak, or Rostrum (anatomy), rostrum, situated in the buccal mass and surrounded by the muscular Cephalopod limb, head appendages. The Dorsal (anatomy), dorsal (upper) mandible fits into the ventral (lower) mandible and together they function in a scissor-like fashion.Young, R.E., M. Vecchione & K.M. Mangold (1999)Cephalopoda Glossary Tree of Life Web Project. The beak may also be referred to as the mandibles or jaws.Tanabe, K., Y. Hikida & Y. Iba (2006). Two coleoid jaws from the Upper Cretaceous of Hokkaido, Japan. ''Journal of Paleontology'' 80(1): 138–145. These beaks are different from Beak, bird beaks because they crush bone while most bird beaks do not. Fossilized remains of beaks are known from a number of cephalopod-groups, both extant and extinct, including squids, octopus, octopodes, belemnites, and vampyromorphs. Aptychus, Aptychi - paired plate-like structures found in ammonites - may also have been jaw elements. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
