No peptidoglycan in their cell walls o rRNA subunit sequences NO KNOWN HUMAN PATHOGENS Many are extremophiles Salt-halophyle Temperature-thermophyl Live in deep ocean vents high in pressure and salt concentration Archaea are not restricted to extreme habitats Archaea account for 20-30% of marine microbial cells Chapter 31 What is the biggest Organism Ever?
