Figure 8. Light and electron micrographs of colponemids.

(a–f) Colponema edaphicum: a) large food vacuole is visible, b) cell division, (c, d) two heterodymanic flagella and (e, f) extrusive organelle toxicyst (TEM), ((a–c), f) from Tikhonenkov et al. [64], (d, e) from Mylnikov et al. [65]; g) Colponema marisrubri (from Mylnikov and Tikhonenkov [25]). a.f – anterior flagellum, f.v – food vacuole, p.f – posterior flagellum, c.v – contractile vacuole, ac – acronema, tc – toxicyst. Scales: (a–e), g) –10 µm; f) –1 µm.
