Fig. 2. Frontonia ocularis in vivo (A–D) and after protargol impregnation (E–G). A – ventral view of a typical individual; B – ventral view showing position of contractile vacuoles; C – different body shapes; D – extruded extrusomes; E, F – infraciliature in ventral and dorsal views, macronucleus, and contractile vacuole pore; G – infraciliature of the buccal area. CV – contractile vacuole, CVP – contractile vacuole pore, Ma – macronucleus, P1–P3 – peniculi 1, 2, 3, PM – paroral membrane, PK – postoral kineties, VK – vestibular kineties. Scale bars: A = 60 μm, E, F = 40 μm.
