Virivore (equivalently virovore) comes from the English prefix viro- meaning virus, derived from the Latin word for poison, and the suffix -vore from the Latin word vorare, meaning to eat, or to devour; therefore, a virivore is an organism that consumes viruses. Virivory is a well-described process in which organisms, primarily heterotrophic protists, consume viruses, though some metazoans are known to do so, as well.

The cells that result from elongation without division have multiple chromosomal copies.
