Description of ParamoebidaeLocomotive form with digitiform, blunt subpseudopodia frequently extending from the anterior hyaloplasm; temporarily lacking in some species. Floating form often with radiating pseudopodia. Uninucleate with central nucleolus. One genus of this family, Paramoeba, contains parasomes (DNA-rich intracellular inclusions situated adjacent to cell nucleus). These intracellular bodies can be stained with the DNA specific fluorochrome, DAPI (Rogerson, 1988). Family diagnosis emended by Page (1987). At the ultrastructural level, two features are of diagnostic importance: a) surface layer is complex and highly differentiated as a cuticle or as boat-shaped microscales discernable at the TEM level b) pseudopodia are without a filamentous core (as in Vexilliferidae).
