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 ...
An amoeba of the genus Mayorella (Amoebozoa, Discosea) Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm. During locomotion, the endoplasm flows forwards and the ...
It is a member of the Filasterea, that is the sister-group to Choanoflagellatea and Metazoa. [2] [3] Two Ministeria amoebae species have been reported so far, [4] both of them from coastal marine water samples: M. vibrans and M. marisola. [1] However, there is currently only one culture available, that of Ministeria vibrans.
Amoeba is a genus of single-celled amoeboids in the family Amoebidae. [2] The type species of the genus is Amoeba proteus , a common freshwater organism, widely studied in classrooms and laboratories.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

The best-understood contractile vacuoles belong to the protists Paramecium, Amoeba, Dictyostelium and Trypanosoma, and to a lesser extent the green alga Chlamydomonas. Not all species that possess a contractile vacuole are freshwater organisms; some marine, soil microorganisms and parasites also have a contractile vacuole.
At the beginning of the series, Osmosis "Ozzy" Jones (voiced by Phil LaMarr impersonating Chris Rock from the film), a white blood cell with an impulsive personality and a penchant for challenging authority, and Drix (voiced by Jeff Bennett impersonating David Hyde Pierce in the same film), a straight-laced and by-the-books cold pill, pursue a scarlet fever bacterium (voiced by Tim Curry).
