Archaebacteria organisms are prokaryotic, which means the cell/cells have no nucleus. They are also unicellular, meaning made up of one cell, and make their own food; or are autotrophic. In addition, Archea commonly live in very extreme environments, such as the bottom of the ocean near deep sea smokers, in sulfur pools, or in the Dead Sea. Finally, they reproduce asexually. Archeabcateria are classified into three types: heat lovers, salt lovers, and methane makers. some examples of these organisms are Acidilobales, Sulfolobales, (both which have no common name) Methanogens (arthrolegentis), Halophiles (halophilic eubacterium), and Thermoacidophilic bacteria.
