Spounalikevirus is a genus of viruses in the order Caudovirales, in the family Myoviridae, in the subfamily Spounavirinae. Bacteria serve as natural hosts. There is currently only one species in this genus: the type species Bacillus phage SPO1.
Viruses in Spounalikevirus are non-enveloped, with head-tail geometries, and T=16 symmetry. The diameter is around 108 nm, with a length of 140 nm. Genomes are linear, around 145kb in length. The genome codes for 200 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. Bacteria serve as the natural host. Transmission routes are passive diffusion.
