Taxonomy distribution
Virus family
    Virus genus (top 12)
    Virus host (top 12)
    Taxonomy and host counts are aggregated from the full export metadata over all 113 members; the member table above shows only a sample. Dominant virus family: Marnaviridae. Host species are annotated only for NCBI-sourced genomes; members from metagenomic sources count as "unknown".
