The gut microbial communities in grey mullets at the phylum level. (A) The structure of gut microbial compositions (relative abundance of phyla). (B) The membership of gut microbial communities (number of taxa present in each phylum category). Others categories include unclassified bacteria and low abundant phyla. X axis shows the sample IDs; JV is juvenile, AD is adult, NWP1 is cryptic species 1, NWP2 is cryptic species 2, and NWP3 is cryptic species 3. There were 12 juvenile samples (NWP1 n = 6; NWP2 n = 6) and 16 adult samples (NWP1 n = 8; NWP2 n = 4; NWP3 n = 4).
