Pandoravirus
Virus classification
Group: Group I (dsDNA)
Order: Unassigned
Family: Pandoraviridae
Genus: Pandoravirus
Species

Pandoravirus is a genus of very large viruses, with the largest genomes of any viral genus.[1] Like the other very large viruses Mimivirus, Pithovirus and Megavirus, Pandoravirus infects amoebas. Its genome, with 1.9 to 2.5 megabases of DNA, is twice as large as that of Megavirus.[2] It differs greatly from the other large viruses in appearance and in genome structure.[3]

Although the capsid of Pithovirus is 50% larger in size,[4] Pandoravirus has the largest genome among all viruses.[3]
