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.

Dimorpha (die-morph-a), the genus contains helioflagellates in which there are two flagella and in which the axonemes terminate on a microtubule organizing centre located near the front of the cell. This is the motile form. Phase contrast.

Dimorpha (die-morph-a), the genus contains helioflagellates in which there are two flagella and in which the axonemes terminate on a microtubule organizing centre located near the front of the cell. Normally the arms do not branch and nor do they have strongly developed extrusomes, so this organism is identified only tentatively to this genus. This taxon may produce arm-less swimming cells, illustrated in another image. 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.
