- Are prokaryotes.

- Specially resistant to high temperatures and high acid concentrations.

- Contain plasma membranes which have high amounts of saturated fats.

- Enzymes are able to withstand extreme conditions without denaturation.

- Multiplication may be by binary fission, budding, fragmentation, or other mechanisms.
