Captovirus
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]

Structure
Model of the virion of AFV-1, Captovirus (cross section)
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.[1]

Life cycle
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.[1]
