Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, [8] often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. [ 7 ] [ 9 ] In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom Protista [ 10 ] or the kingdom ...
Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
The locomotion of Amoeba proteus exhibits chaotic dynamics described by a low-dimensional chaotic attractor with a correlation dimension around 3-4, indicating that the seemingly random movement arises from deterministic cooperative interactions among a small number of processes like sol-gel transformations, cytoplasmic streaming, and calcium-mediated reactions.

A protist (/ ˈ p r oʊ t ɪ s t / PROH-tist) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus.Protists do not form a natural group, or clade, but are a polyphyletic grouping of several independent clades that evolved from the last eukaryotic common ancestor.
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 ...

Paramecium caudatum [1] is a species of unicellular protist in the phylum Ciliophora. [2] They can reach 0.33 mm in length and are covered with minute hair-like organelles called cilia. [3] The cilia are used in locomotion and feeding. [2] The species is very common, and widespread in marine, brackish and freshwater environments. [4] [5]
This category contains valid protist species names, i.e. eukaryotes that are not plants, fungi or animals. Alternate names (i.e. junior synonyms) are not included here.. Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus ar
