Elaeorhanis (elle-lay-owe-rane-us) an amoeba with fine filose pseudopodia living within a loose lorica of mucus and accreted detritus. Traditionally aligned with heliozoa, which it is obviously not. The orange globule is reminiscent of Diplophrys. Differential interference contrast.

Elaeorhanis (elle-lay-owe-rane-us) an amoeba with fine filose pseudopodia living within a loose lorica of mucus and accreted detritus. Traditionally aligned with heliozoa, which it obviously not. This image shows the pseudopodia. Phase contrast.

Amphimonas allantoideus Ruinen, 1938. Cells are 10-12 x 3-4 microns, and flexible. The cell body is curved, and circular in cross section. There is a large posterior vacuole. There are two flagella of equal length. The anterior flagellum produces the thrust for movement. T^his species is of dubious status.

Amphimonas angulatus Namyslowski, 1913. Cells are oval, 4-6 microns long, not metabolic with two flagella of equal length. The flagella are about the cell length. The cytoplasm is homogeneous, without granulation. This taxon is of dubious status because the description is inadequate.

Amphimonas cuneatus Namyslowski, 1913. Cells are 10 microns long and 4 microns wide, and metabolic with two flagella of unequal length. The flagella are about 50 microns long. Cytoplasm homogenous without vacuoles or granulation. This taxon is of dubious status because the description is inadequate.

Amphimonas divaricans Kent, 1880. Body irregular, rounded posteriorly, the anterior margin is abruptly and obliquely truncate, its two lateral sides projecting forwards, the flagella similar in length and character, and arise at the apices of the two anterior angular extensions, about twice the diameter of the body, with a slender straight pedicel that has a similar length to that of the flagella. Height of body 2.5 microns, greatest width 3 microns Reminiscent of Reclinomonas.

Amphimonas metabolicus Namyslowski, 1913. Cells are 30 microns long and 5 microns wide, metabolic, with two flagella of equal length. The flagella are about the same length as the cell.

Amphimonas rostratus Namyslowski, 1913. Cells are oval, 4-5.5 microns long, and not metabolic. The cytoplsm is homogeneous, without vacuoles or granulation, the two flagella are of equal length and are about the same length as the cell.

Dimastigamoeba vorax Massart, 1920. Cells with two equal flagella, may swim or glide, cell surface produces short lobose pseudopodia, when gliding, the pseudopodia form at the front end and the flagellated end of the cell is at the posterior. The pseudopodia ingest prey, undigested residues are expelled at the other end of the cell near the flagella. When swimming the flagella are directed to the front.

Quasibodo laughtoni Bernard et al., 2000. Cells are ovoid, bean-shaped or pyriform, circular in cross-section and 6-12 microns long. The flagella insert subapically, with the cell anterior to the flagellar insertion forming a very short protrusion. The anterior flagellum is about the body length, and often holds its distal part in a curve. The posterior flagellum is acronematic (not always visible), three to six times the length of the cell, and forms an obtuse angle with the anterior flagellum. Its anterior portion is adpressed to the cell. The cytoplasm is very hyaline, sometimes with small vacuoles. Cytoplasmic strands form occasionally from the posterior end. The nucleus located in the anterior half of the cell is difficult to see. Cells may rotate during swimming, the posterior flagellum appears to provide the motive force.

Bodopsis platyformis Lackey, 1940. Cells are 15-20 microns long and 12-15 microns wide. Generally round to oval in outline, but when coming to rest, they can be slightly metabolic. A slight indentation in front serves as a mouth region, and at times a few short pseudopodia are extended from here, this is the point of emergence of the flagella. The anterior one is about body length, the trailing flagellum is about two and one half times as long. The nucleus is median, large, conspicuous, with a wide clear zone just inside its membrane. Against the membrane is an accumulation of granules and spherical bodies. Pellicle smooth. Colorless. No feeding or reproduction seen.

Telonema (teal-owe-knee-ma) small marine flagellate, predatory, two flagella emerge from a subapical depression, the cell swims with these flagella pointing to the rear. With a well developed cytoskeleton giving the cell a stiff consistency. This cell has a food particle inside. Phase contrast.

Telonema (teal-owe-knee-ma) subtilis Griessmann, 1913. Cell outline is oval-ovoid. Cells are about 8 microns long, anteriorly narrow and posteriorly broad with a short anterior neck. Two flagella insert below the neck, are acronematic and are slightly longer than the cell. The nucleus is centrally located. The cells swim backward with the flagella, which point behind the swimming cells. Food materials are shown in the posterior end of the cell. Not common.
