Archaebacteria
This is a picture of Halobacteria or Haloarchea, a type of archaebacteria.
Archaebacteria is a Kingdom with unicellular organisms. They are prokaryotic (they don't have a neucleus or membrane bound organelles). Archaebacteria are heterotrophic. They can live in extreme areas such as hot water springs and very salty areas such as the Dead Sea and the Great Salt Lake. They may also live in swamps and animal intestines. They reproduce asexually with budding, bionary fission or fragmentation. In archaebacteria, there are three subgroups. Their names are thermophiles, halophiles, methanogens. In those three subgroups, there are different archeabacteria. Some are: Pyrococcus abyssi, methanotorris igneus, haloarchaea, Tuberculosis, Humicola Insolens, and Haloferax elongans.
