Alviniconcha Okutani & Ohta 1988

Alviniconcha ( 英語 )

由wikipedia EN提供

Alviniconcha is a genus of deep water sea snails, marine gastropod mollusks in the family Provannidae.[1] These snails are part of the fauna of the hydrothermal vents in the Indian and Western Pacific Ocean.[2] These and another genus and species within the same family (Ifremeria nautilei) are the only known currently existing animals whose nutrition is derived from an endosymbiotic relationship with a member of bacteria from phylum Campylobacterota (formerly Epsilonproteobacteria) occurs as an endosymbiont of the gills of Alviniconcha hessleri.[3]

Description

The size of the shell varies between 25 mm and 35 mm. The surface of the shell is studded with hairs on the periostracum, Individuals variation in shell size and the arrangement of the hairs, but the variation does not correspond to individual species.[2]

Species

Until 2014, Alviniconcha consisted solely of the species Alviniconcha hessleri, described in 1988. In 2014, increased recognition of genetic differences between populations resulted in the formal description of five cryptic species within the former A. hessleri that are morphologically indistinguishable from each other but that have consistent differences in mitochondrial DNA sequences.[2]

Species within the genus Alviniconcha include:

  • Alviniconcha adamantis S.B. Johnson, Warén, Tunnicliffe, Van Dover, Wheat, Schultz & Vrijenhoek, 2014
  • Alviniconcha boucheti S.B. Johnson, Warén, Tunnicliffe, Van Dover, Wheat, Schultz & Vrijenhoek, 2014
  • Alviniconcha hessleri Okutani & Ohta, 1988
  • Alviniconcha kojimai S.B. Johnson, Warén, Tunnicliffe, Van Dover, Wheat, Schultz & Vrijenhoek, 2014
  • Alviniconcha marisindica Okutani, 2014
  • Alviniconcha strummeri S.B. Johnson, Warén, Tunnicliffe, Van Dover, Wheat, Schultz & Vrijenhoek, 2014 (named after punk musician Joe Strummer of The Clash)[4]

Alviniconcha ( 葡萄牙語 )

由wikipedia PT提供

Alviniconcha é um género de moluscos mesogastrópodes do oceano profundo pertencentes à família Provannidae[1]. O nome deriva do DSV Alvin (literalmente: "Concha de Alvin"). O género é parte da fauna das fontes hidrotermais de grande profundidade dos oceanos Pacífico e Índico.

O género integra a única espécie animal que se conhece derivar directamente a maioria da sua nutrição de uma relação endossimbiótica com proteobactérias[2].

Espécies

Os exemplares usados para definir as espécies deste género eram conhecidos, mas até 2014 pensava-se que eles pertenciam todos à mesma espécie. O estudo genético "Molecular taxonomy and naming of five cryptic species of Alviniconcha snails (Gastropoda: Abyssochrysoidea) from hydrothermal vents" publicado em 2014 na revista Systematics and Biodiversity permitiu distinguir as cinco espécies de Alviniconcha, que povoam fontes hidrotermais na parte ocidental do oceano Pacífico e na zona já perto do oceano Índico[3].

O género Alviniconcha inclui cinco espécies:
