Moroteuthis
The hooked squid, family Onychoteuthidae, currently comprise about 20–25 species (several known from only single life stages and thus unconfirmed), in six or seven genera. They range in mature mantle length from 7 cm to a suggested length of 2 m for the largest member, ''Onykia robusta''. The family is characterised by the presence of hooks only on the tentacular clubs, a simple, straight, funnel–mantle locking apparatus, and a 'step' inside the jaw angle of the lower beak. With the exception of the Arctic Ocean, the family is found worldwide.

Onykia Robusta
''Onykia robusta'', also known as the robust clubhook squid and often cited by the older name ''Moroteuthis robusta'', is a species of squid in the family Onychoteuthidae. Reaching a mantle length of ,Norman, M.D. 2000. ''Cephalopods: A World Guide''. ConchBooks. it is the largest member of its family and one of the largest of all cephalopods. The tentacular clubs are slender, containing 15–18 club hooks. Arms of the species contain 50–60 suckers, and grow to 90–100% of the mantle length. It is found primarily in the boreal to Temperate Northern Pacific. Confusion with ''Architeuthis'' Some time before 1993, a large individual of ''O. robusta'' was photographed by Japanese diver Kubota H. in shallow water off southern Japan.Ellis, R. 1998.

Cephalopod Beak
All extant cephalopods have a two-part beak, or rostrum, situated in the buccal mass and surrounded by the muscular head appendages. The 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. Fossilised remains of beaks are known from a number of cephalopod groups, both extant and extinct, including squids, octopuses, belemnites, and vampyromorphs. Aptychi – paired plate-like structures found in ammonites – may also have been jaw elements. Composition Composed primarily of chitin and cross-linked proteins, beaks are more-or-less indigestible and are often the only identifiable cephalopod remains found in the stomac ...

Onykia Sp
''Onykia'' is a genus of squids in the family Onychoteuthidae. Due to similarities between the genera, several recent authors consider the genus ''Moroteuthis'' a junior synonym of ''Onykia''.

Onychoteuthis Banksii
''Onychoteuthis banksii'', the common clubhook squid, is a species of squid in the family Onychoteuthidae. It is the type species of the genus '' Onychoteuthis''. This species was thought to have a worldwide distribution but with the revision of the genus '' Onychoteuthis'' in 2010, it is now accepted that ''Onychoteuthis banksii'' is restricted to the central and northern Atlantic and the Gulf of Mexico while a recently described species, '' Onychoteuthis horstkottei'', is found in the Pacific Ocean. The type locality is the Gulf of Guinea. Description The maximum mantle length is . The eight arms are all of equal size and the tentacles are 27% of the mantle length. The clubs on the end of the tentacles bear two rows of strongly recurved hooks. There are two intestinal photophores, the anterior one being larger than the posterior one; there are also photophores in the form of whitish patches on the underside of the eyeballs. Most squid live in deep water, and in these, the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Elford Leach
William Elford Leach FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Department of the British Museum, where he had responsibility for the zoological collections. Here he threw himself into the task of reorganising and modernising these col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychoteuthis Bergii
''Onychoteuthis bergii'' is a species of hooked squid from the family Onychoteuthidae. The species was originally described by Hinrich Lichtenstein from specimens taken near the Cape of Good Hope and is the type species of the genus '' Onychoteuthis''. Until recently it was considered to be a junior synonym of ''Onychoteuthis banksii'', but a re-examination of the type material, the lectotype and paralectotype which are deposited in the Natural History Museum, Berlin The Natural History Museum (german: Museum für Naturkunde) is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major muse ..., showed that there were morphological differences which supported the status of ''O. bergii'' as a valid species. The species is found in the eastern South Atlantic and Indian Oceans. References {{Taxonbar, from=Q13924104 Squid Cephalopods described in 1818< ...

Adolf Appelloef
Adolf (also spelt Adolph or Adolphe, Adolfo and when Latinised Adolphus) is a given name used in German-speaking countries, Scandinavia, the Netherlands and Flanders, France, Italy, Spain, Portugal, Latin America and to a lesser extent in various Central European and East European countries with non-Germanic languages, such as Lithuanian Adolfas and Latvian Ādolfs. Adolphus can also appear as a surname, as in John Adolphus, the English historian. The female forms Adolphine and Adolpha are far more rare than the male names. The name is a compound derived from the Old High German ''Athalwolf'' (or ''Hadulf''), a composition of ''athal'', or ''adal'', meaning "noble" (or '' had(u)''-, meaning "battle, combat"), and ''wolf''. The name is cognate to the Anglo-Saxon name '' Æthelwulf'' (also Eadulf or Eadwulf). The name can also be derived from the ancient Germanic elements "Wald" meaning "power", "brightness" and wolf (Waldwulf). Due to negative associations with Adolf H ...

Onychoteuthis Mollis
''Onychoteuthis'' is a genus of squid in the family Onychoteuthidae. The type species is '' Onychoteuthis bergii''. While the genus is found worldwide in tropical and subtropical oceans, they can also occur in the North Pacific Ocean. There were previously considered to be four species in the genus but there are now considered to be roughly 10. These squid are frequently observed in the surface waters at night and they are often caught using dipnet at nightlight stations. The young squid are usually the only specimens captured using standard midwater trawls, the older squid are apparently able to avoid the trawls. They can, however be collected from the air as individuals are able to leap high out of the water, sometimes even landing on the deck of a ship. Anatomy Most species belonging to the genus have a mantle length of under 200 mm, however the larger members may measure over 300 mm. The species in this genus have a densely muscular, cylindrical mantle which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychoteuthis Compacta
''Onychoteuthis compacta'' is a species of squid in the family Onychoteuthidae, known to occur in Hawaiian waters. as well as in other areas of the Central Pacific and western north-central Atlantic, it probably has a circumglobar distribution. The species is known to have a mantle length of at least 122 mm for females and 127 mm for males. Each tentacle In zoology, a tentacle is a flexible, mobile, and elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work ma ... has 22 club hooks, measuring approximately 30 mm in mature specimens.
