Another unique feature of archaea is that they can survive in extreme conditions, such as extremely hot, extremely cold or extremely salty water. Also, archaea cell walls lack peptidoglycan, which is present in bacteria. In most archaea the wall is assembled from surface-layer proteins, which form a rigid array of protein molecules to cover the outside of the cell, similar to a chainmail.
