Cafeteria cells are encountered as very small sessile or free-swimming naked trophic cells.
| Uninucleate trophic cells are approximately bean-shaped and only 3-10 Ám
long. The two
flagella are subapically inserted, often from a conspicuous pocket over
which hangs a liplike
protrusion. The anterior flagellum is usually directed forward, the
posterior flagellum backward.
Sessile cells rest on the tip of the posterior flagellum, with the anterior
flagellum beating in a
helicoidal fashion and directing a current of water onto the cell body.
This behavior is diagnostic for bicosoecids.
