Finnlakeviridae is a family of bacterial viruses that is not assigned to any higher taxonomic ranks. The family contains a single genus, Finnlakevirus, which contains a single species, Flavobacterium virus FLiP.[1][2] This virus was isolated in 2010, with its gram-negative host Flavobacterium, from Lake Jyväsjärvi, a boreal freshwater habitat in Central Finland, and is the first described single-stranded DNA virus with an internal membrane.[2]

Genome organization of Flavobacterium phage FLiP.

The genome is circular single-stranded DNA of about 9200 nucleotides in length.[2]
