11. Pyrodictium Geogemma P: Crenarcheota Ignicoccus

13. Methanobacterium Methanopyrus Halobacterium P: Euryarcheota Haloarcula

14. Korarcheota

15. Recently discovered Phylum: Nanoarcheota: some of smallest cells known (“nano” = 1/billionth -> implies “very small” ) Species: Nanoarcheum equitans From the report in Nature (5/2/02): Found “on the surface of another Archaean called Ignicoccus (green), whose cells are about 2 millionths of a metre (2  m) across. Each cell sported 30 to 50 Nanoarcheota cells (red).” “The organisms are about 400 billionths of a metre (0.4  m) across - more than six million would fit on the head of a pin.”
