Fish gut microbiota clustered separately from the microbiotas of other vertebrates. a PCoA of the binary Jaccard indices of the gut microbiota from fish and various vertebrates (iguanas, snakes, aquatic mammals, birds, terrestrial mammals, and humans; sequences were obtained from the NCBI SRA and the Qiita server). b–d PCoA plots colored by the relative abundance of the phyla Proteobacteria (b), Firmicutes (c), and Bacteroidetes (d). Color intensity is proportional to the relative abundance (%) of each phylum
