Echinamoeba thermarum is an extremely thermophilic amoeba species discovered in various hot springs worldwide. It is notable for its ability to thrive at high temperatures, with an optimal growth temperature of 50°C (122°F).
Normal volume of a human red blood cell: 2 × 10 −16: Average volume of a lymphocyte: 3.3 × 10 −16: Mean volume of a neutrophil granulocyte: 4.2 × 10 −16: Volume of an average monocyte: 1 × 10 −15: One picolitre 2–9 × 10 −15: One drop from a high resolution colour inkjet printer: 1.3 × 10 −13: a very fine grain of sand (0.063 ...
Amoebozoa vary greatly in size. Some are only 10–20 μm in diameter, while others are among the largest protozoa. The well-known species Amoeba proteus, which may reach 800 μm in length, is often studied in schools and laboratories as a representative cell or model organism, partly because of its convenient size.
The exametre (SI symbol: Em) is a unit of length in the metric system equal to 10 18 meters. To help compare different distances this section lists lengths between 10 18 m (1 Em or 105.7 light-years) and 10 19 m (10 Em or 1,057 light-years). 1.2 Em – 129 light-years – diameter of Messier 13 (a typical globular cluster)
An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods.

Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.

All species also contain an epipodium which is a terminal aperture in the protist's structure. The size of Difflugia is found to range from 15μm all the way up to 500μm. During cell division, the particles collected that have been used to produce the test are directly passed on to the daughter cell.
Chaos is a genus of single-celled amoeboid organisms in the family Amoebidae.The largest and most-known species, the so-called "giant amoeba" (Chaos carolinensis), can reach lengths up to 5 mm, although most specimens fall between 1 and 3 mm. [3] [4] [5]
