ICTV Virus Taxonomy Profile: Krittikaviridae 2026.

The family Krittikaviridae includes dsDNA viruses associated with the marine archaeal lineage Poseidoniales. These viruses have been identified through metagenomic analysis of brackish estuarine samples and are closely related to other 'magroviruses'. The family belongs to the order Magrovirales and includes the genus Velanvirus and the species Velanvirus brisbanense. Viruses in the family have a genome of about 80 kbp that includes modules for DNA replication and virion morphogenesis. Krittikavirids are predicted to form virions with an icosahedral capsid and helical tail, characteristic of viruses belonging to the class Caudoviricetes. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Krittikaviridae, which is available at ictv.global/report/krittikaviridae.
