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] Members of this genus closely resemble those of the genus Amoeba and share the same general morphology, producing numerous cylindrical pseudopods , each of which is ...
Pelomyxa is a genus of giant flagellar amoebae, usually 500–800 μm but occasionally up to 5 mm in length, found in anaerobic or microaerobic bottom sediments of stagnant freshwater ponds or slow-moving streams. [1] The genus was created by R. Greeff, in 1874, with Pelomyxa palustris as its type species. [2]
Amoeba proteus is a large species of amoeba closely related to another genus of giant amoebae, Chaos. As such, the species is sometimes given the alternative scientific name Chaos diffluens. [1] [2] Amoeba proteus in locomotion. This protozoan uses extensions called pseudopodia to move and to eat smaller unicellular organisms.
Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. 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 ...
However, soon thereafter genetic remnants of mitochondria were found in various Archamoebae, suggesting that these organisms had diverged after the evolution of mitochondria, but had lost their mitochondria over time, and are more closely related to various amoebae and slime molds.
The bacteria is usually only found in the mouth, far from the colon. In the mouth, it’s one of the most common types of disease-causing bacteria , linked to gum disease and plaque buildup.
Hundreds of species of the ciliate genus Paramecium [3] or flagellated Euglena [4] are found in marine, brackish, and freshwater reservoirs; the green algae Chlamydomonas is distributed in soil and fresh water world-wide; [5] parasites from the genus Giardia colonize intestines of several vertebrate species.

An FDA inspection of a Tom’s of Maine manufacturing facility led to the discovery of “significant violations,” including bacteria in water used to make toothpaste and a black “mold-like ...
