The host coral Acropora granulosa (pictured), the tissues layers of the host coral and regions of bacterial association (a) and Venn diagram of the inclusion of niche habitat associations within the coral microbiome (b). Coral holobiont is indicated in red, coral symbiotic tissue community is indicated in blue and coral endosymbiotic community is indicated in green.
