Page "Bacteriophage" Paragraph 5

The dsDNA tailed phages, or Caudovirales, account for 95 % of all the phages reported in the scientific literature, and possibly make up the majority of phages on the planet.

However, other phages occur abundantly in the biosphere, with different virions, genomes and lifestyles.

Phages are classified by the International Committee on Taxonomy of Viruses ( ICTV ) according to morphology and nucleic acid.
