In Amoeba, the pseudopodia are approximately tubular, and rounded at the ends (lobose). The cell's overall shape may change rapidly as pseudopodia are extended and retracted into the cell body. An Amoeba may produce many pseudopodia at once, especially when freely floating. When crawling rapidly along a surface, the cell may take a roughly ...
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.
The Amoebidae are a family of Amoebozoa, [1] including naked amoebae that produce multiple pseudopodia of indeterminate length. These are roughly cylindrical with granular endoplasm and no subpseudopodia, as found in other members of the class Tubulinea.

Among the more basal Cercozoa is Reticulamoeba, an amoeboflagellate with reticulose pseudopods (reticulopodia), filopodia that join into a net-like structure. [ 6 ] Amoebozoa contains several groups of amoeboflagellates with one [ 7 ] or two flagella [ 8 ] and lobose pseudopods, which are rounder and more blunt-ended than filopodia.
The class Tubulinea, as of 2022, is classified into three major groups: Corycida, Echinamoebida and Elardia. The most taxonomically abundant group is Elardia, which contains the testate amoebae of Arcellinida and the naked amoebae of orders Leptomyxida and Euamoebida .
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]
