portrait

Descrição:

Portrait of Bodo, a small phagotrophic colorless bodonid flagellate. Bodo has a short anterior flagellum (usually not well seen because it is closely applied to the body) and a long easily seen posterior flagellum by which it attaches to the substrate. Posterior flagellum imparts sudden flicking (saltatorial) movements. Bodo lacks the prominent rostrum seen in Rhynchomonas. Bacteria are ingested at a cytostome located at the base of the flagellar insertion. A single contractile vacuole is visible in this image. From freshwater pond near Boise, Idaho. Phase contrast.
