Nanohalarchaeota

Several species of nanhoaloarchaea encode CRISPR-Cas systems suggesting that they are parasitized by viruses. Consistently, metagenomic analysis has revealed that nanohaloarchaea are associated with diverse viruses. These viruses belong to four morphologically different groups, including those with head-tailed (class Caudoviricetes), tailless icoahedral (realm Singelaviria), enveloped pleomorphic and spindle-shaped virions. Currently known nanohaloarchaeal viruses have been classified into seven distinct families. ==Taxonomy==

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI). }} Phylum "Nanohalarchaeota" corrig.
