ELO: Endozoicomonas-like organisms, Anaplasma group. Myco: Mycoplasma group. Franc: Francisella group. Other: shows the minimum and maximum proportion of reads with similarity to other symbionts, grouped either with Chlamydia, Bacteroidetes, Spirochetes or sulfur-oxidizing endosymbiotic bacteria. Envirom: environmental, shows the minimum and maximum proportion of reads that were not identified as symbionts and were then classified as environmental. Unclass: unclassified, shows the minimum and maximum proportion of reads per sample that were not included within the top ten percent of reads in any one sample or which were not identified as the most abundant in any one sample and which were therefore not investigated. T: tissue analyzed as follows: “G” gill; “D” digestive gland; “M” mantle, and “V” various organs (for DNA extracted from FFPE). Fix: DNA extracted from ethanol fixed (EtOH) or from formalin-fixed and paraffin-embedded (FFPE) tissues. N°: number of samples sequenced per group. Details of the metadata associated with each sample can be found in Supplementary Table 1.
