|Group:||Group I (dsDNA)|
Siphoviridae are a family of double-stranded DNA viruses infecting only bacteria. These viruses may also be referred to as bacteriophages. The characteristic structural features of this family are a nonenveloped head and noncontractile tail.
Virions of viruses in this family have an icosahedral capsid (morphotype B1) or a prolate capsid (morphotype B2). These capsids have no envelope and are generally about 60 nanometers in diameter. Members of this family are also characterized by their filamentous, cross-banded, noncontractile tails, usually with short terminal and subterminal fibers.
The organisation of genes in the genera L5likevirus, Lambdalikevirus, Phic3unalikevirus, and Psimunalikevirus and the proposed genera Sfi2likevirus, Sfi1likevirus, Sk1likevirus, and Tm4likevirus suggests that these may form a lamba supergroup (or subfamily).
The c2-like viruses have oblate heads.

In addition to the above viruses, many members of Siphoviridae have been grouped into an unclassified group with no genus assignment. This group includes numerous phages known to infect Lactobacillus, Mycobacterium, Streptococcus, and other groups of bacteria.
