Pseudobodo (sue-doe-bow-dough) is a naked bicosoecid stramenopile. As with other bicosoecids, it attaches to the substrate by the tip of the recurrent flagellum. The anterior flagellum is directed away from the substrate, beats with an undulating pattern, and draws a current of water with suspended bacteria (its food) towards the cell. The cell has a ridge to one side of the flagellum and this marks the margin of the ingestion region. Phase contrast.

Pseudobodo (sued-oh-boe-dough) tremulans Griessmann, 1913. Cells are about 4.5 - 6 microns long with an anterior collar around the anterior part of the cell in unstressed feeding cells. The insertion sites of the two flagella are separated by a protrusion at the anterior of the cell. The anterior flagellum has a sine-wave beating pattern and is about 3.5 times the length of the cell, and the posterior flagellum is about twice the length of the cell and may attach to the substrate by its tip. When the cells move, the anterior collar may be hard to see. The cells move by swimming with the anterior flagellum directed forwards. Not common.

This image was made from samples taken during a scientific cruise in the Pacific. Water was filtered to concentrate the organisms that were present, then dried onto a thin sheet of plastic and then shadowed with a fine layer of metal to provide contrast. The preparation was then observed with an electron-microscope. This technique has been used to document the diversity of marine microbes, especially, protists in the oceans.
