Table 2 Relative abundance (%) of OTUs that were consistently detected in all the crabs and rarely found in sediment (i.e. relative abundance <0.01%). Values are reported per species along the three sampling locations (KSA: Saudi Arabia, KY: Kenya, and RSA: South Africa). Taxonomic information of OTUs’ closest relatives obtained from the National Center for Biotechnology Information database is reported as phylum, class, genus/species and accession number. OTUs belonging to the Ilumatobacter genus are indicated in bold. Crab species: AA, A. albimana; CI, C. inversa; TU, T. urvillei; AO, A. occidentalis; PC, P. chlorophthalmus
