Archea is the unicellular prokaryotes that can inhabit an extreme range of environments due to their cellular adaptations. Their cell wall does not contain peptidoglycans but contains, S-layers. Archaea are most adapted to the extreme growth conditions such as extremely hot, cold, salinity or any other conditions that allow the other organisms to survive.

Archae can be halophilic, thermophilic and psychrophilic. Archaea contains a pigment, which allows it to synthesize ATP (adenosine triphosphate) using light energy, whereas some of the species can fix carbon (but cannot do photosynthesis). Archea are the smallest and oldest organisms available.

Archaebacteria are believed to have originated at a time when there were extreme conditions in the biosphere. Even today they are found in environments where other kinds of bacteria cannot survive. So they are considered to be the oldest of the living fossils. Eg. Methanobacterium, Methonococcus etc. All of them are not halophiles. Only some forms like Halobacterium, Halococcus can survive under extreme saline conditions. All of them are not fossils because many forms are still surviving and flourishing.
