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.
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.
Evosea is a strongly supported clade of eukaryotes containing four large groups of amoebozoans: Eumycetozoa or "true" slime molds, [3] Variosea, Cutosea and Archamoebae.It is defined on a node-based approach as the least-inclusive clade containing Dictyostelium discoideum (a true slime mold), Protostelium nocturnum (a variosean), Squamamoeba japonica (a cutosean), and Entamoeba histolytica (an ...
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 .
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.
Lobosa is a taxonomic group of amoebae in the phylum Amoebozoa.Most lobosans possess broad, bluntly rounded pseudopods, although one genus in the group, the recently discovered Sapocribrum, has slender and threadlike (filose) pseudopodia. [1]
The genus Difflugia was initially discovered in 1815 by L, Leclerc, [2] but its infra-generic classification as a group is still unclear. The genus Difflugia is the oldest and most diverse of the testate amoebae. It contains more than 300 species and countless subspecies since even minor differences in morphology result in classification as a ...
