Coraliomargarita akajimensis Yoon et al. 2007 is the type species of the genus Coraliomargari-ta. C. akajimensis is an obligately aerobic, Gram-negative, non-spore-forming, non-motile, spherical bacterium that was isolated from seawater surrounding the hard coral Galaxea fas-cicularis. C. akajimensis is of special interest because of its phylogenetic position in a genom-ically under-studied area of the bacterial diversity. Here we describe the features of this or-ganism, together with the complete genome sequence, and annotation. This is the first com-plete genome sequence of a member of the family Puniceicoccaceae. The 3,750,771 bp long genome with its 3,137 protein-coding and 55 RNA genes is a part of the Genomic Encyclo-pedia of Bacteria and Archaea project.
