Turriviridae is a family of viruses; it contains only one genus, Alphaturrivirus. The archaea Sulfolobus solfataricus serve as natural hosts. There are two species in the genus Alphaturrivirus.
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:
Viruses in Turriviridae have icosahedral geometries, and T=31 symmetry. The diameter is around 74 nm. Genomes are circular.
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Sulfolobus solfataricus serves as the natural host. Transmission routes are passive diffusion.
