Neighbor joining tree of 16S rRNA sequences of Kiwa sp. nov. ESR (blue), Kiwa hirsuta (green), Kiwa puravida (yellow), Shinkaia crosnieri (red), Rimicaris exoculata (black), and Vulcanolepas sp. (pink). (A) Epsilonproteobacteria, (B) Gammaproteobacteria and Bacteroidetes. The tree was calculated within arb using neighbor joining with the Felsenstein correction using only sequences >1300 nt. Shorter sequences were then added by parsimony within arb. The length of each sequence is shown in the tree, followed by the Genbank accession number. Bootstrap values were calculated with the arb parsimony interactive tool. Only bootstrap values >50% are shown.
