Archaea
They were initially given the name archaebacteria, but this classification is outdated.
Their cells have unique properties separating them from the other two domains of life. The Archaea are further divided into four recognized phyla. Classification is difficult because the majority have not been studied in the laboratory and have only been detected by analysis of their nucleic in samples from their environment.
