The archaebacteria Kingdom has three phylums. The three phylums are:

• Methanogens
• Halophiles
• Thermoacidophiles

  The methanogen phylum is full of bacteria that live in the intestines of other organisms. They are helpful in breaking down food in the intestines and provide energy.

  The Halophils phylum can only live in large bodies of saltwater.

  The Thermoacidophiles phylum contains bacteria that are found in hot water and sulfer springs. They can handle temperatures up to an amazing 80 degrees celcius.

An example of an organism in the Archaebacteria kingdom is the Methanosarcina barkeri. They live in certain organs of cows and make their own energy by digesting cellulose and other polysaccarides. More info:

• They are anaerobic and very sensitive to oxygen
• They are from the Methanogen phylum
• Live in very harsh environmental conditions
• They are slow developers and are sensitive to sudden change in physical and chemical conditions
• They are a target for genetic analysis
