Cirroctopus Antarctica
''Cirroctopus antartica'' is a species of deep-sea octopus known from only two specimens, both collected around the Antarctic Peninsula. Its 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 o ... is like the letter "U" in shape. It is possible, though not certain, that ''C. antarctica'' is a synonym of ''C. glacialis''. References Molluscs described in 1986 Octopuses {{octopus-stub ...

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 ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past ...

Cirrate Shell
Cirrate octopuses possess a well-developed internal shell that supports their muscular swimming fins. This is in contrast to the more familiar, finless, incirrate octopuses, in which the shell remnant is either present as a pair of stylets or absent altogether. The cirrate shell is quite unlike that of any other living cephalopod group and has its own dedicated set of descriptive terms. It is usually roughly arch- or saddle-shaped and is rather soft, being similar in consistency to cartilage. Each of the eight extant cirrate genera is characterised by a distinct shell morphology: *Cirroteuthidae **''Cirroteuthis'' — saddle-shaped, with large wings **''Cirrothauma'' — butterfly-shaped *Opisthoteuthidae **''Cirroctopus'' — V-shaped, lateral wings tapering to fine points **'' Cryptoteuthis'' — U-shaped, each lateral wing ending in broad lobe with pointed projection **'' Grimpoteuthis'' — U-shaped, lateral wings ending bluntly **'' Luteuthis'' — W-shaped **''Opisthote ...

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] |
Molluscs Described In 1986
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
