Cirroctopus
''Cirroctopus'' is a genus of four species of octopuses within the monotypic family Cirroctopodidae. Members of this genus have larger fins than other Cirrata, cirrate octopuses, and tend to be more muscular.Vecchione, Michael and Richard E. Young. 2016. Cirroctopodidae Collins and Villanueva 2006.

Cirroctopus Glacialis
''Cirroctopus glacialis'' is an octopus located in the Palmer Archipelago of Antarctica. Its shell is v-shaped, and it has a distinctive pigmentation pattern on its web's oral face. ''C. glacialis'' is thought to be demersal The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a laye ..., like other members of the genus Cirroctopus. These octopuses are found between 333 and 914 meters deep. Their population is currently unknown. References Octopuses {{octopus-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirroctopus Hochbergi
''Cirroctopus hochbergi'' (common name: four-blotched umbrella octopus) is a cirrate octopus living between 800 and 1,070 meters deep off the coast of New Zealand. The species is known from 48 specimens. It is most similar to its sister taxon, ''Cirroctopus mawsoni''; however, ''C. mawsoni's'' ventral pigmentation is lighter, and the two species have been found in very different areas (''C. mawsoni'' is only known in waters near Antarctica). This octopus lives near cold seeps and seamounts. It is theorized that it and all other cirrate octopuses live in the demersal zone. Threats While ''C. hochbergi'' is not used by humans, it is often taken as bycatch. One of the greatest threats to the species is trawling, which damages its habitat. There are an estimated 250 to 1,000 mature individuals. ''C. hochbergi's'' population is currently decreasing, and it may be locally extinct Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal tha ...

Cirrata
Cirrina or Cirrata is a suborder and one of the two main divisions of octopuses. Cirrate octopuses have a small, internal shell and two fins on their head, while their sister suborder Incirrina has neither. The fins of cirrate octopods are associated with a unique cartilage-like shell in a shell sac. In cross-section, the fins have distinct proximal and distal regions, both of which are covered by a thin surface sheath of muscle. The suborder is named for small, cilia-like strands (cirri) on the arms of the octopus, a pair for each sucker. These are thought to play some role in feeding, perhaps by creating currents of water that help bring food closer to the beak. Cirrate octopuses are noteworthy for lacking ink sacs. Phylogeny A molecular phylogeny based on mitochondrial and nuclear DNA marker sequences by Sanchez et al., 2018, shows that the Cirrina is paraphyletic, i.e. it is not a single clade. Instead, a clade containing Opisthoteuthidae and Cirroctopodidae is siste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Naef
Adolf Naef (1 May 1883 – 11 May 1949) was a Swiss zoologist and palaeontologist who worked on cephalopods and systematics. Although he struggled with academic politics throughout his career and difficult conditions during World War I and II, his work had lasting influences on the fields of phylogenetics, morphology, and embryology. Life Naef was born in Herisau, Switzerland, to parents Martin and Berta. In 1904, he began studying philosophy and literature at the University of Zurich, but soon switched to natural sciences. He graduated in 1908 and went on to pursue a PhD under the guidance of Arnold Lang (1855—1914), a former Professor of Jena University and close friend of Ernst Haeckel as well as a long-time associate of Anton Dohrn.Rieppel, Olivier (2016).

Tsunemi Kubodera
is a Japanese zoologist with the National Museum of Nature and Science. On September 30, 2004, Kubodera and his team became the first people to ''photograph'' a live giant squid in its natural habitat.Kubodera, T. & K. Mori 2005First-ever observations of a live giant squid in the wild.''Proceedings of the Royal Society B: Biological Sciences'', 272(1581):2583-2586. Two years later, on December 4, 2006, he also managed to successfully ''film'' a live adult giant squid for the first time ever. On July 10, 2012, Kubodera, together with Steve O'Shea and Edith Widder, became the first to ''film'' a live giant squid ''in its natural habitat'' from a submersible off the Bonin Islands. In addition to these firsts involving the giant squid, in 2005, Kubodera also became the first to film the Dana octopus squid (''Taningia danae'') in its natural habitat. Finding the giant squid With his partner Kyoichi Mori of the Ogasawara Whale Watching Association, Kubodera captured photos of t ...

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 ...
