Metagenomic surveys have revealed an astounding reservoir of viral genetic diversity in single-celled marine eukaryotes known as protists, but the vast majority of these viruses have not been directly observed, and information about their protist hosts remains fragmentary. The 2023 discovery of mirusviruses provides a striking example, whereby metagenomic surveys of samples collected by the\n                      <jats:italic toggle=\"yes\">Tara<\/jats:italic>\n                      Oceans expedition led to the discovery of a new phylum of viruses, the\n                      <jats:italic toggle=\"yes\">Mirusviricota<\/jats:italic>\n                      , with remarkable chimeric genomes encoding structural proteins from herpesviruses and enzymes from giant eukaryotic viruses.
