Pandoravirus Pandoraviridae is a proposed family of double-stranded DNA viruses that infect amoebae.

There is only one genus in this family: Pandoravirus.

[1][2] The viruses in this family are the second largest known virus (~1 micrometer) in capsid length, after Pithovirus (1.5 micrometer).

[3] Pandoravirus has the largest viral genome known, containing double-stranded DNA of 1.9 to 2.5 megabase pairs.

[4][1] These viruses appear to be related to the phycodnaviruses.
