Structure
Viruses in Cripavirus are non-enveloped, have capsids of 12 capsomers, and have icosahedral geometries with T=pseudo3 symmetry. The diameter is around 30 nm. Genomes are linear and non-segmented, around 8.5–10.2kb in length, and has a VPg (genome linked viral protein) on the 5' end. The 5' end also has a series of C's near it, while the 3' end has a series of A's near it. The genome has 2 open reading frames.
Life cycle
Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription is the method of transcription. Translation takes place by viral initiation, and ribosomal skipping. Invertebrates serve as the natural host. Transmission routes are contamination.
