The term “colony morphology” refers to the visible characteristics of a colony. Colonies that differ in appearance are typically different bacterial strains, species, or genera. However, colony morphology is not a reliable way to identify bacteria, as many different types of bacteria have similar colony morphology.

Aside from their undeniably unique morphology and abilities, Archaea are also important because of their place in the history of life. Most researchers believe that some of the species we still see today may have been around during the most tumultuous and destructive periods on Earth, when life had to survive in savage (or extreme) conditions of heat and atmospheric shifts.
