Galiteuthis
''Galiteuthis'' is a genus of glass squids from the family Cranchiidae and the subfamily Taoniinae. Squids in the genus ''Galiteuthis'' are large squids with mantle lengths measuring up to 660mm, although it has been suggested that mantle length could reach as much as 2.7m. The most distinctive feature of the speciesa in this genus are they have hooks on the tentacular clubs while there are no hooks on the arms, and by their long, thin, terminal fins. The genus contains bioluminescent species. Species Five species are currently recognised: *'' Galiteuthis armata'' Joubin, 1898 *''Galiteuthis glacialis'' (Chun, 1906) *'' Galiteuthis pacifica'' ( Robson, 1948) *''Galiteuthis phyllura'' Berry A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples are strawberries, raspb ..., 1911 *'' Galiteuthis suhmi'' ( Hoyle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galiteuthis Glacialis
''Galiteuthis glacialis'' is a species of glass squid from the Antarctic Convergence. It is in the cranchiidae family and subfamily taoniinae. They are endemic to the Antarctic and are found in the Southern Ocean, around the Weddell Sea and South Shetland Islands. ''Galiteuthis glacialis'' are one of the most plentiful and widely dispersed species of Antarctic squid. These squids are found in the Mesopelagic zone, mesopelagic and Bathyal zone, bathypelagic layers of the open ocean and demonstrate vertical migration. They can reach a maximum mantle length of 500 mm (0.5m). Distribution ''Galiteuthis glacialis'' is found predominantly in the Southern Ocean. It occupies the northern and eastern parts of the Weddell Sea, but is less abundant in the Southernmost part. This species prefers the open ocean and steep continental slope of the Eastern Weddell Sea. They are also found around the South Shetland Islands. As ''G. glacialis'' matures and its mantle size increases, it moves to dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taoniinae
Taoniinae is a subfamily containing ten genera of glass squids. Description Unlike Cranchiinae , the other subfamily within Cranchiidae , Taoniinae all lack cartilaginous strips which extend back from the funnel-mantle point of fusion. Their funnels are free laterally, and they have one to three photophores on the eyes. The largest photophore is crescent-shaped for most genera, but it's triangular in '' Helicocranchia'', a semicircle in '' Bathothauma'', and circular in '' Sandalops''. This is in contrast to glass squids in the subfamily Cranchiinae, which have at least four small photophores which are round or oval in shape. In addition, males lack hectocotyli; these are arms which have evolved to specialize in storage and transfer of spermatophores to females. Taoniinae are also often larger than Cranchiinae and have darker beaks. Another characteristic is that a Taoniinae's caecum, is smaller than its stomach; in Cranchiinae, the caecum is larger than the stomach. Taxono ...

Galiteuthis Phyllura
''Galiteuthis phyllura'', also known as the cockatoo squid, is a species of glass squid, possibly the largest in the genus. In 1984, the Russian stern-trawler ''Novoulianovsk'' brought up the remains of a gigantic specimen of ''G. phyllura'' from a depth of 1000–1300 m in the Sea of Okhotsk. Nesis, K.N. (1985)Гигантский кальмар в Охотском море giant squid in the Sea of Okhotsk.''Priroda'' 98510): 112–113. Based on this material, which consisted of a 40 cm long arm and 115 cm tentacle, Kir Nesis estimated the mantle length at 265–275 cm, and the total length at over 4 m. This would make it the second largest squid species in terms of mantle length, after only the colossal squid, and even surpassing the mantle length of the giant squid. However, Nesis added that "because of its narrow body, we conclude that its mass is consistently lower than that of the other large squids". Ellis, R. (1998). ''The Search for the Giant Squid''.

Glass Squid
The family (biology), family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, cranchiid, cranch squid, or bathyscaphoid squid. Cranchiid squid occur in surface and midwater depths of open oceans around the world. They range in mantle (mollusc), mantle length from to over , in the case of the colossal squid. The common name, glass squid, derives from the Transparency (optics), transparent nature of most species. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage. They are characterised by a swollen body and short arms, which bear two rows of Sucker (cephalopod anatomy), suckers or hooks. The third cephalopod arm, arm pair is often enlarged. Many species are Bioluminescence, bioluminescent organisms and possess light organs on the undersides of their cephalopod eye, eyes, used to cancel their shadows. Eye morphology varies widely, ranging from large and circular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

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.
