Captovirus is a genus of viruses in the family Ungulaviridae. Archaea acidianus serve as natural hosts. There is only one species in this genus: Captovirus AFV1, also known as Acidianus filamentous virus 1.[1] [2]
Viruses in Captovirus are enveloped, with rod-shaped geometries. The diameter is around 24 nm, with a length of 900 nm. Genomes are linear, around 20kb in length. The genome codes for 40 proteins.

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. Archaea acidianus serve as the natural host. Transmission routes are passive diffusion.
