Smallest organisms were first described in 1996 by Philippa Uwins of the University of Queensland. Smallest organisms The smallest organisms found on Earth can be determined according to various aspects of organism size; including volume, mass, height, length, or genome size. Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered. Furthermore, there is some debate over the definition of life, and what entities qualify as organisms; consequently the smallest known organism (microorganism) is debatable. Many biologists consider viruses to be non-living because they lack a cellular structure and cannot metabolize by themselves, requiring a host
