Grimpoteuthis Innominata 73 Mm ML
''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 (mollusc), 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, ''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''.

Guy Coburn Robson
Guy Coburn Robson (1888–1945) was a British zoologist, specializing in Mollusca, who first named and described '' Mesonychoteuthis hamiltoni'', the colossal squid. Robson studied at the marine biological station in Naples, and joined the staff of the Natural History Museum in 1911, becoming Deputy Keeper of the Zoology Department from 1931 to 1936. Evolution Robson is best known for his major book ''The Variations of Animals in Nature'' (co-authored with O. W. Richards, 1936) which argued that although the fact of evolution is well established, the mechanisms are largely hypothetical and undemonstrated.Allee, W. C. (1937)''The Variation of Animals in Nature: A Critical Summary and Judgment of Evolutionary Theories by G. C. Robson, O. W. Richards'' ''American Journal of Sociology'' 42 (4): 596–597. The book claims that most differences among animal populations and related species are non-adaptive. It was published before major developments in the modern synthesis and contains ...

Madeira Abyssal Plain
Madeira Abyssal Plain, also called Madeira Plain, is an abyssal plain situated at the center and deepest part of the Canary Basin. It is a north-northeast to south-southeast elongated basin that almost parallels the Mid-Atlantic Ridge. Its western boundary is marked by a chain of seamounts known as the either Seewarte Seamounts or Atlantis-Great Meteor Seamount Chain. Its eastern boundary is a distinct break of slope that marks the foot of the African Continental Rise. This abyssal plain occupies an area of about . Across this basin, slope angles are generally less than 0.01°.Alibés, B., Canals, M., Alonso, B., Lebreiro, S.M. and Weaver, P.P.E., 1996.

Addison Emery Verrill
Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor. Life Verrill was born on February 9, 1839 in Greenwood, Maine, the son of George Washington Verrill and Lucy (Hillborn) Verrill. As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals. When he moved with his family to Norway, Maine at age fourteen he attended secondary school at the Norway Liberal Institute. Verrill started college in 1859 at Harvard University and studied under Louis Agassiz. He graduated in 1862 with a B.A. He went on scientific collecting trips with Alpheus Hyatt and Nathaniel Shaler in the summer of 1860 to Trenton Point, Maine and Mount Desert Island and in the summer of 1861 to Anticosti Island and Labrador. In 1864 Verrill made reports on mining, or prospective mining, properties in New Hampshire, New York, and Pennsylvania. Tw ...

Cirroteuthis
''Cirroteuthis muelleri'' was the first cirrate octopus species (and genus) to be scientifically described (in 1836). It is closely related to the genus ''Cirrothauma'' within the family Cirroteuthidae. At present the genus contains a single recognized species restricted to the Arctic Ocean and northern basins of the Atlantic and Pacific, but other species may be present in the southern hemisphere.Vecchione, M. & R.E. Young 2003''Cirroteuthis'' Eschricht, 1836 The Tree of Life Web Project. Description ''Cirroteuthis muelleri'' can reach a maximum length of 400 mm (mantle length 170 mm). Statements that ''C. muelleri'' reaches up to 1.5 m total length are erroneous (and involve unidentified '' Cirrothauma'', then regarded as ''Cirroteuthis'' sp., being mistakenly assumed to be ''C. muelleri''). It is off white or pale purple, with the inner side of the arms and the webs being brownish-purple. The head has well developed eyes with lenses. The upper and lower beaks are thin and rela ...

Grimpoteuthis Meangensis
''Grimpoteuthis meangensis'' is known from either one or two specimens, though the second may be of a completely different species. The first was damaged. Both were found by William Evans Hoyle within one year of each other, and no other animals of the species have been identified since 1886. Description and habitat The type specimen, or original specimen, was found off the south Philippines. It lives about 1,000 meters beneath the water's surface. Like other members of its family, Opisthoteuthidae, ''G. meangensis'' could be demersal. The second specimen was discovered 2,000 meters south of where the first specimen was found. This octopus' mantle reaches 53 millimeters long, and it weighs at least 1,345 grams when wet. Every arm has between 60 and 70 suckers, which are small. Like other cirrates, ''G. meangensis'' has a web covering its arms to some degree; the web of ''G. meangensis'' covers the majority of its arms. The cirri on these arms are short. The fins ''G. meangensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grimpoteuthis Innominata
''Grimpoteuthis innominata'' is a species of small, pelagic octopus only known from two specimens. Steve O'Shea discovered it in 1999, and created the genus ''Enigmateuthis'' to contain it. Martin Collins placed the species in the genus ''Grimpoteuthis''. Description and habitat ''Grimpoteuthis innominata'' has been found in Chatham Rise to the east of New Zealand, where it lives 2,000 meters deep in open ocean. Like other members of Grimpoteuthidae, ''G. innominata'' is most likely demersal. This octopus' mantle reaches 43 millimeters long, and its total body is 156 millimeters long.

Emperor Seamounts
An emperor (from la, imperator, via fro, empereor) is a monarch, and usually the sovereign ruler of an empire or another type of imperial realm. Empress, the female equivalent, may indicate an emperor's wife ( empress consort), mother (empress dowager), or a woman who rules in her own right and name (empress regnant). Emperors are generally recognized to be of the highest monarchic honor and rank, surpassing kings. In Europe, the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe. The Emperor of Japan is the only currently reigning monarch whose title is translated into English as "Emperor". Both emperors and kings are monarchs or sovereigns, but both emperor and empress are considered the higher monarchical titles. In as much as there is a strict definition of emperor, it is that ...

Stauroteuthis
''Stauroteuthis'' is a genus of deepwater octopus, a cephalopod mollusk. This is the only genus in the family Stauroteuthidae, and only two species have been described in this genus. The organisms live below water depth; although sometimes found as deep as underwater, they generally live at a water depth of around . They do not possess a radula. The stauroteuthids have the distinction of being one of the few bioluminescent octopuses; some of the muscle cells that control the suckers in most species have been replaced with photophores which are believed to fool prey by directing them towards the mouth. Species * ''Stauroteuthis gilchristi'' is only known from two localities in the south Atlantic; these two localities may even represent different species. * ''Stauroteuthis syrtensis'' is widespread in the North Atlantic. The population size of ''S. syrtensis'' is unknown. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
