Phylogenetic classification of sponge–bacterial communities and identification of dominant bacterial species. (a) Phylogenetic classification (at the level of phylum and subphylum) of the bacterial communities in sponges, sediment, and seawater using Naïve Bayesian classification with the Silva bacterial database (version 119) as the reference. (b) Classification of the top 20 dominant OTUs (at a distance of 0.03) in each of the samples. Read abundance is indicated as the relative percentage of the total bacterial reads analyzed for each sponge
