Nanoarchaeota (Greek, "dwarf or tiny ancient one") is a proposed phylum (Candidatus Nanoarchaeota) in the domain Archaea that currently has only one representative, Nanoarchaeum equitans, which was discovered in a submarine hydrothermal vent and first described in 2002. (wikipedia.org)

EURYARCHAEOTA1
Figure 22.14 Archaea are separated into four phyla: the Korarchaeota, Euryarchaeota, Crenarchaeota, and Nanoarchaeota. (openstax.org)
Genomes1
As a result of this machine learning framework, CheckM2 is also highly accurate on organisms with reduced genomes or unusual biology, such as the Nanoarchaeota or Patescibacteria. (nih.gov)
Unusual1
Despite small size, a reduced genome and limited respiration, members of the Nanoarchaeota have unusual metabolic features. (wikipedia.org)
