Lambdatorquevirus is a genus of viruses, in the family Anelloviridae. Sea lions serve as natural hosts. There are five species in this genus.{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/2956.html|publisher=ExPASy|accessdate=13 August 2015}}{{cite web|title=Virus Taxonomy: 2024 Release|url=https://ictv.global/taxonomy|publisher=International Committee on Taxonomy of Viruses|access-date=25 March 2025}}
Taxonomy
Structure
Viruses in Lambdatorquevirus are non-enveloped, with icosahedral geometries, and T=1 symmetry. The diameter is around 19-27 nm. Genomes are circular, around 2.1kb in length. The genome has 2 open reading frames.

Life cycle
Viral replication is nuclear. Entry into the host cell is achieved by penetration into the host cell. Replication follows the ssDNA rolling circle model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export. Sea lions serve as the natural host.
