Pelagibacter ubique is one of the smallest known free-living bacteria, with a length of 370 to 890 nm (0.00037 to 0.00089 mm) and an average cell diameter of 120 to 200 nm (0.00012 to 0.00020 mm). They also have the smallest free-living bacterium genome: 1.3 Mbp, 1354 protein genes, 35 RNA genes. They are one of the most common and smallest ...
Ostreococcus tauri was discovered in 1994 in the Thau lagoon, France, in a year-long study of the picoplankton population of the lagoon using flow cytometry. O. tauri was found to be the main component of the picoplankton population in the lagoon, and images of cells produced by transmission electron microscopy revealed the smallest yet described free-living eukaryotic cells.

Mycoplasma species are among the smallest free-living organisms (about 0.2 - 0.3 μm in diameter). [ 11 ] [ 12 ] They have been found in the pleural cavities of cattle suffering from pleuropneumonia. These organisms are often called MLO (mycoplasma-like organisms) or, formerly, PPLO (pleuropneumonia-like organisms).
Pelagibacter ubique, the ubiquitous free-living ocean bacterium with the smallest (~1100) number of genes The smallest known genome of a free-living bacterium is 1.3 Mb with ~1100 genes. [ 10 ] However, significantly more reduced genomes are commonly observed in naturally occurring symbiotic and parasitic organisms.
The book has been published in a limited edition of 100 copies by the laboratory and requires a scanning electron microscope to read the text. In December 2012, a Library Edition of the book was published with a full title of Teeny Ted from Turnip Town & the Tale of Scale: A Scientific Book of Word Puzzles and an ISBN 978-1-894897-36-5 .

Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
It is a living organism (contains DNA or some analogue, and reproduces).; Has a morphology similar to Actinomycetes and fungi.; Nanobes are about 20 nm in diameter, which may be too small to contain the basic elements for an organism to exist (DNA, ribosomes, etc.), suggesting that if they grow and reproduce they would need to do so in an unconventional way.
