Figure 2 in Frontonia anatolica n. sp., a new peniculid ciliate (Protista, Ciliophora) from Lake Van, Turkey

Figure 2. Photomicrographs of Frontonia anatolica n. sp. from live specimens (a–f, j), after silver nitrate (g, i, l, m), and silver carbonate impregnation (h, k). a–d) General morphology of live specimens. e) A view of contractile vacuole. Arrow marks excretory pore, arrowheads mark collecting canals. f) Surface view showing extrusomes (arrowheads). g) Ciliary pattern of dorsal side. h) Ventral view of silver carbonate impregnated specimen showing somatic and oral structures in same focal plane due to the strong body flattening. i) Silverline system. j) Extrusomes beneath pellicule. k) Oral apparatus in early divisional stage. l, m) Oral ciliature showing 3 almost parallel, slightly curved peniculi on the left wall of the oral cavity and the paroral membrane vestibular kineties on the right. Arrowheads mark postoral kineties. CV = Contractile vacuole; Di = Diatom; E = Extrusome; EP = Excretory pore; LD = Lipid droplets?; Ma= Macronucleus; Mi= Micronucleus; OA= Oral apparatus; PM= Paroral membrane; P1–3 = Peniculus 1–3; PeS = Preoral suture; PoS = Postoral suture; VK1–3 = Vestibular kineties 1–3.
