Paramoebidae

Korotnevella stella, from Microworld.

Belongs within: Amoebozoa.

The Paramoebidae are a family of flattened amoebae that produce finger-like anterior subpseudopodia. At least some paramoebids host minute endosymbionts close to the nucleus that were once mistaken for organelles, called parasomes.

Characters (from Microworld): Locomotive 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. Surface layer complex, highly differentiated as a cuticle or as boat-shaped microscales discernable at the TEM level. Pseudopodia without a filamentous core.
