Taxonomic summary of the viral communities associated with coral reef sponges. Column headings display nine sponge species from the Great Barrier Reef and seven from the Red Sea. The top 30 most frequent taxonomic assignments are summarised at the family level based on a normalised comparison (normalised gene count ~ 33,250 per dataset) of viral RefSeq gene assignments in MEGAN6 using parameters defined in Laffy et al. [30]. Abundance for each viral taxa was calculated using contig coverage estimates to identify proportional representation within each dataset. Only viral sequences that underwent taxonomic assignment and datapoints with abundance values of 10 or more were included within this plot. RNA viral taxonomic assignments were filtered from the final dataset
