Fig. 2. Metaradiophrya lumbrici (Dujardin, 1841), Slovak specimens in vivo. A. Semi-schematic diagram of the ventral side, showing the fibrillar hook as well as the contractile vacuole and the somatic ciliary pattern. Arrowheads mark the subapical suture extending from the right body margin over the hook towards the left body margin. B. Detail of the anterior body portion, showing the fibrillar hook and its associated fibers. There are on average 6 (5–7) fibers attached to the upper right side of the longer arm, on average 33 (30–37) fibers to the ventral side of the longer arm and on average 11 (8–13) fibers to the left side of the shorter arm. C. Shape variants of fibrillar hooks. The hook is composed of two unequally long arms: the longer arm is flat and 25–35 µm long, while the shorter arm appears slightly more robust at the base and is 8–13 µm long. D–E. Lateral somatic kineties form a right and a left subterminal suture in the posterior body region. F. Ventral view, showing the general body organization. G. The cytoplasm contains innumerable granules being ca 0.4 µm across and rod-like bacteria being about 3–15 µm long. Scale bars: A, F = 50 µm; B = 10 µm.
