Grimpoteuthis Umbellata
''Grimpoteuthis umbellata'', known from three specimens, is the type species of ''Grimpoteuthis''. Description and habitat The species is not well known. The three specimens were taken from different locations; the largest was found off the Azores, and the smaller two were found off Morocco. Of the three specimens, only two were actually members of ''Grimpoteuthis''. Only one of these two is still extant, and it is in poor condition. The largest was found at a depth of 2,235 meters. ''Grimpoteuthis umbellata'' could be the senior synonym of either '' Grimpoteuthis wuelkeri'' or ''Grimpoteuthis discoveryi ''Grimpoteuthis discoveryi'' is a small species of octopus known from more than 50 specimens. It was described in 2003, but specimens have been found as early as 1910. The type species was found at 49°35'N, 14°01'W. Description At maximum, ''Gr ...''. The large specimen is 250 millimeters long, and its mantle is 46 millimeters long. Its first arm is 100 millimeters long. ...

Paul Henri Fischer
Paul Henri Fischer (also spelled Paul-Henri Fischer), (7 July 1835 Paris – 29 November 1893) was a French physician, zoologist and paleontologist. He is generally known as Paul Fischer. Biography He studied science and medicine, securing doctorates in both, and became assistant in paleontology at the National Museum of Natural History in Paris. He was made assistant naturalist there in 1872. Beginning in 1856, he was joint editor, with A. C. Bernardi to start with, of the ''Journal de Conchyliologie''. He served several terms as president of the Société Géologique de France Lactalis is a French multinational dairy products corporation, owned by the Besnier family and based in Laval, Mayenne, France.

In 1880, he was a member of the commission for submarine dredging. Bibliography *''Faune conchyliologique ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Grimpoteuthis
''Grimpoteuthis'' is a genus of pelagic umbrella octopuses known as the dumbo octopuses. The name "dumbo" originates from their resemblance to the title character of Disney's 1941 film ''Dumbo'', having a prominent ear-like fin which extends from the mantle above each eye. There are 17 species recognized in the genus. Prey include crustaceans, bivalves, worms and copepods. The average life span of various ''Grimpoteuthis'' species is 3 to 5 years. Species and taxonomy As noted above, many species collected on the ''Challenger'' expedition were initially classified in the genera '' Cirroteuthis'' and '' Stauroteuthis.'' Several species formerly classified as ''Grimpoteuthis'' were moved to genera '' Cirroctopus'' and '' Opisthoteuthis''. A new family, Grimpoteuthididae (alternatively spelled Grimpoteuthidae), has been proposed to accommodate ''Grimpoteuthis'' and those of genera ''Enigmatiteuthis'', ''Cryptoteuthis'', and ''Luteuthis''.

Grimpoteuthis Wuelkeri
''Grimpoteuthis wuelkeri'' is a medium-sized octopus characterized from multiple specimens. Description and habitat This octopus is known from the continental slope in the northern Atlantic Ocean at 2,055 meters deep. It is likely demersal. At maximum, its body is 400 millimeters long, and its mantle is 115 millimeters long. Its fin span is around 70% of the octopus' total length. The shell Shell may refer to: Architecture and design * Shell (structure), a thin structure ** Concrete shell, a thin shell of concrete, usually with no interior columns or exterior buttresses ** Thin-shell structure Science Biology * Seashell, a hard ou ... is shaped like a letter "U". Its arms have around 60 to 70 suckers each, and these suckers aren't sexually dimorphic. A web covers about 2/3 of its arms. It has a robust shell, with a thick basal portion, and strong attachments from their fins. References Octopuses Molluscs of the Atlantic Ocean Molluscs described in 1920 {{octo ...

Grimpoteuthis Discoveryi
''Grimpoteuthis discoveryi'' is a small species of octopus known from more than 50 specimens. It was described in 2003, but specimens have been found as early as 1910. The type species was found at 49°35'N, 14°01'W. Description At maximum, ''Grimpoteuthis discoveryis mantle is 58 millimeters in length, and its body in total reaches 370 millimeters. Its arms are long. ''G. discoveryi'', like other cirrates, has a web covering its arms to some degree; this species' web reaches 2/3 of its arm length. The suckers on its arms number between 56 and 61. The suckers of female specimens are smaller than the suckers of males, and are also differently shaped. The range in mantle size are larger in females (32-58mm) than males (25-52mm). Thposterior salivary glandsand radula are both absent in this species, however, itanterior salivary glandsare present. The species' body is white, and its eyes are dark grey or black when preserved. It's possible that ''G. discoveryi'' is actually two se ...

Octopuses
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
