Dataset supporting description of the new mussel species of genus Gigantidas (Bivalvia: Mytilidae) and metagenomic data of bacterial community in the host mussel gill tissue

摘要

This article contains supplementary data from the research paper entitled “A newly discoveredGigantidasbivalve mussel from the Onnuri Vent Field on the northern Central Indian Ridge” , describes a new mussel species within the subfamily Bathymodiolinae namedGigantidas vrijenhoeki. Data are comprised of two parts: 1) shell image and molecular analyses ofG. vrijenhoekiand 2) metagenomic community analyses of gill-associated symbiotic bacteria onG. vrijenhoeki. G. vrijenhoekidata were obtained from type specimens described in Jang et al. 2020 . The molecular analysis was conducted by calculating genetic distance at intra- and inter-specific level within genusGigantidasbased on the sequence data of two mitochondrial genes (COIandND4). The metagenomic dataset of gill-associated symbionts were generated by Illumina Miseq sequencing of the V3-V4 region of16SrRNA from 12 specimens ofG. vrijenhoekicollected from the same vent site, Onnuri Vent Field.
