Fig. 3 in Morphological and Morphogenetic Redescriptions and SSU rRNA Gene-based Phylogeny of the Poorly-known Species Euplotes amieti Dragesco, 1970 (Ciliophora, Euplotida)

Fig. 3. Morphogenesis of Euplotes amieti after protargol impregnation. (A, B) Ventral (A) and dorsal (B) view of the same specimen at an early stage to show the five frontal-ventral-transverse cirral streaks and oral primordium within which membranelles are forming (arrow). (C, D) Ventral (C) and dorsal (D) view of the same specimen at a middle stage to show the completion of the cirral formation, the differen- tiation of caudal cirri at posterior ends of the two rightmost dorsal anlagen (arrowheads), the de novo formation of the new marginal cirri and the frontal cirrus I/1 in both proter and opisthe (arrows). (E, F) Ventral (E) and dorsal (F) view, showing the migration of newly formed cirri and the development of dorsal kineties, arrowheads show the marginal cirri. (G, H) Ventral (G) and dorsal (H) side of the same divider at a late stage showing infraciliature and nuclear apparatus. Scale bars: A–D = 100 μm; E–H = 150 μm.
