Kiwa Tyleri
''Kiwa tyleri'', the "Hoff crab", is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS ''James Cook'', owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David Hasselhoff. The 2010 expedition to explore hydrothermal vents on the East Scotia Ridge was the second of three expeditions to the Southern Ocean by the UK led research consortium, ChEsSo (Chemosynthetic Ecosystems of the Southern Ocean). Distribution This species – the only member of its genus found outside the Pacific Ocean, is known from two sites adjacent to and on the chimney sides of hydrothermal vents in the East Scotia Ridge of the south Atlantic Ocean: from around depth at the E9 vent site and from around depth at the E2 site. Over time, this creature has adapted to the crushin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Gigantopelta Chessoia
''Gigantopelta chessoia'' is a species of deep sea snail from hydrothermal vents, a marine gastropod mollusk in the family Peltospiridae. Taxonomy The first information about this species, under the name "Peltospiroidea n. sp." or "peltospiroid gastropod", was published on 3 January 2012. Peltospiroidea is the name of a superfamily of gastropods that was used in the taxonomy of the Gastropoda (Ponder & Lindberg, 1997). It contained the only extant family Peltospiridae (and some prehistoric gastropod families). However, the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005) does not use the name Peltospiroidea (in that system, the family Peltopiridae is placed within the Neomphaloidea). It was described as a new species within new genus ''Gigantopelta'' in 2015 and it was classified within the family Peltospiridae. Distribution This species is known from two sites near hydrothermal vents in the East Scotia Ridge of the south Atlantic Ocean: from 2,394 m depth at the E9 ...

Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chela (organ)
A chela ()also called a claw, nipper, or pinceris a pincer (biology), pincer-like organ at the end of certain limbs of some arthropods. The name comes from Ancient Greek , through New Latin '. The plural form is chelae. Legs bearing a chela are called chelipeds. Another name is ''claw'' because most chelae are curved and have a sharp point like a claw. Chelae can be present at the tips of arthropod legs as well as their pedipalps. Chelae are distinct from spider chelicerae in that they do not contain venomous glands and cannot distribute venom.

Kiwa Puravida
''Kiwa puravida'' is a species of deep-sea dwelling decapod, a member of the genus '' Kiwa'', a genus of animals sometimes informally known as "yeti crabs". The crabs live at deep-sea cold seeps where they feed on symbiotic Pseudomonadota, which they cultivate on hair-like projections on their claws. The bacteria metabolise hydrogen sulfide and methane produced by the seeps, and are harvested by the animals' comb-like mouthparts. Among the other deep-sea animals that make use of such symbionts this species is unique in that it actively waves its appendages over the vents in order to provide the bacteria with more oxygen and nutrients. ''Kiwa puravida'' was discovered living on the deep sea bottom off the coast of Costa Rica in 2006 by Andrew Thurber, William J. Jones and Kareen Schnabel. The only other members of its family, '' Kiwa hirsuta'', and the Hoff crab, or '' Kiwa tyleri'', are crabs with similarly hairy claws. ''Kiwa hirsuta'' was discovered in 2005 near Easter ...

Dense Mass Of Anomuran Crab Kiwa Around Deep-sea Hydrothermal Vent
Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ''ρ'' (the lower case Greek letter rho), although the Latin letter ''D'' can also be used. Mathematically, density is defined as mass divided by volume: : \rho = \frac where ''ρ'' is the density, ''m'' is the mass, and ''V'' is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight. For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure. To simplify comparisons of density across different systems ...

Kiwa Hirsuta
''Kiwa hirsuta'' is a crustacean discovered in 2005 in the South Pacific Ocean. This decapod, which is approximately long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Its discoverers dubbed it the "yeti lobster" or "yeti crab". Identification ''K. hirsuta'' was discovered in March 2005 by a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, California and Michel Segonzac of the Ifremer and a Census of Marine Life scientist using the submarine DSV ''Alvin'', operating from RV ''Atlantis''. The discovery was announced on 7 March 2006. It was found along the Pacific-Antarctic Ridge, south of Easter Island at a depth of , living on hydrothermal vents. Based on both morphology and molecular data, the organism was deemed to form a new biological family (Kiwaidae); a second species, ''Kiwa puravida'', was discovered in 2006 and described in 2011.
