Correlation-based network of intestinal bacteria genera (relative abundance ≥ 0.5%) from three Alviniconcha marisindica individuals. Network analysis displays the intra-associations within each sub-community and inter-associations between sub-communities. Node size is proportional to the number of connections (i.e. degree of connectivity). Connection between nodes represents strong [Spearman correlation efficiency > 0.8 (yellow) or <  − 0.8 (blue)] and significant (p-value < 0.01) correlation. The same colour of nodes shows their highly modularised (clustered) property within the network
