Kiwa puravida

Kiwapurabida is a deep-sea leg, a member of the genus Kiwa, sometimes called "snowman club". [1]

The crab lives in the cold waters of the deep sea and eats symbiosis Proteobacteria growing on the nails' hair. Bacteria metabolize hydrogen sulfide and methane produced by exudate and are harvested by animal combs. Among the other deep-sea animals that use this symbiont, this species is unique in that it actively wields its attachment to the vent to supply more oxygen and nutrients to the bacteria. [3]

In 2006, William Thurber, William J. Jones, Kareen Schnabel discovered the Kiwa puravida inhabiting 1,000 m (3,300 ft) of deep sea off Costa Rica. [4] [2] [5] The other other members of the family, Kiwa hirsuta and Hoff Crab, or Kiwa tyleri are crabs with similar nails. Kiwahilsta was discovered near Easter Island in 2005 and Kiwa Tire was found near the hot spot of East Scotia Ridge in 2015. [2] [6] A specific nickname puravida (literally meaning "pure life") comes from Costa Rica's Spanish slang (used to answer "How are you" or "Thank you") . Hommage [2]

Kiwa hirsuta discovered in 2005 and Kiwa puravida discovered in 2006 are listed. The third species, commonly known as "Hofkani", was found in the east Scotia ridge and was named after discoverer Kiwa Tyleri, University of Southampton Paul Taylor. Analysis of mitochondrial and nuclear rDNA markers confirmed that it is genetically different from K. hirusuta. The same data shows the difference between the two species of 12 million years ago. In 2011, a deformation similar to East Scotia Ridge was collected at the vent of East Indian West Ridge and West Indian Ridge.

Mawaceae, found only in deep-sea chemically synthesized ecosystems, contains four Michaelia, two of which have been recently described. Kiwa hirsuta is a kind of family and family of this genus and was discovered near the hydrothermal vent near the Pacific Antarctic Ridge in 2005 (Figure 2). The new family is explained based on its slim covered glitter and clearly localized shell, and other letters. Propagation of apparently chemically synthesized filamentous fungi found in bristles led McPherson et al. It is speculated that Kiwide may be dependent in part on these bacteria as a nutrient source, which was later confirmed. In 2006, the second species, Kiwa puravida, was discovered from a cold methane leak in the Pacific continental slope near Costa Rica. Isotope analysis showed that the main meal is an exogenous bacterium growing on the shell. And they were scraped away by a special third jaw "comb".
