Bodo designis (beau-dough), small flagellate, with two flagella, moving with a rotating motion, skipping or gliding motion. One of the most common of the bodonids, found in almost every habitat so far studied. Moves by skipping near surfaces. It stops to ingest attached or detrital bacteria with the anterior mouth (in the rostrum). Phase contrast, rotten picture.

The flagella insert into a small subapical pocket, as is suggested by the subapical depression. One of the most common of the bodonids, found in almost every habitat so far studied.

Bodo (Boe-dough) designis Skuja, 1948. Cell outline is usually elliptical. Cells are 4 to 7 microns long with two unequal flagella emerging from a subapical pocket and are somewhat flexible. The anterior flagellum is about the length of the cell or slightly shorter and curves back over the rostrum. The anterior flagellum wraps around the anterior part of the cell and the mouth is pressed against food particles when the cell is feeding. The acronematic posterior flagellum is about 2 - 4 times the length of the cell and has a sinuous profile in swimming cells. The cells rotate around their longitudinal axes when swimming. The nucleus is located near the middle of the cell. Commonly observed.

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.

These two profiles of Bodo designis show its two flagella attached at the anterior end of the cell, and an acronematic posterior flagellum. The specimens were collected with a coverslip from sediments at low tide at Eel Pond, Woods Hole, MA. Photo by Banoo Malik.
