Molecular sequences reveal three distinct groups within the Archaea, the phyla Euryarchaeota, Crenarchaeota and Korarchaeota. The Euryarchaeota are probably the best known and include many methane producers and salt-loving archaeans. The Crenarchaeota include the species that live at the highest temperatures of any known living things, though a wide variety have recently been found in soil and water at more moderate temperatures. The Korarchaeota were known only from their DNA sequences. Since the discovery that methanogens belong to the Archaea, many other groups have turned up in habitats such as the ocean surface, deep ocean muds, salt marshes, animal guts and oil reserves.

"Augarchaeota" (previously "Aigarchaeota") is an archaeal phylum of which the main representative is "Candidatus Caldiarchaeum subterraneum". It is not yet clear if this represents a new phylum or a Nitrososphaeria class, since the genome of "Ca.

Thermoproteati is a kingdom of archaea. Its synonym, "TACK", is an acronym for "Thaumarchaeota" (now Nitrososphaerota), "Aigarchaeota", "Crenarchaeota" (now Thermoproteota), and "Korarchaeota", the first groups discovered.
