Kariarchaeum pelagius is a member of the DPANN archaea group, representing ultra-small, genomically streamlined organisms found in pelagic marine environments. Like other DPANN archaea, it likely relies on metabolic partnerships with other microorganisms due to its reduced biosynthetic capabilities. Its discovery in open ocean waters extended knowledge of DPANN archaeal diversity beyond sediment and acidic environments.
