"Ultrastructure of the ovarian follicles, oviducts and oocytes of Gyrocotyle urna (Neodermata: Gyrocotylidea)"@en . "An ultrastructural study of the ovarian follicles and their associated oviducts of the cestode Gyrocotyle urna Grube et Wagener, 1852, a parasite from the spiral valve of the rabbit fish, Chimaera monstrosa L., was undertaken. The ooplasm of mature oocytes contain lipid droplets (2.0 x 1.8 mu m) and cortical granules (0.26 x 0.19 mu m). The cytoplasm of primary and secondary oocytes contains centrioles, indicating the presence of the so-called %22centriole cycle%22 during oocyte divisions. A morphological variation between different oviducts was observed. A division of the ovary into separated parts with their own collecting ducts as that typical of Gyrocotyle has been observed in neodermates, basal monogenean family Chimaericolidae, and Neoophora (some Proseriata and Fecampiidae). Ultrastructural data thus reveal several unique morphological characteristics of gyrocotylideans, the most basal taxon of tapeworms (Cestoda)." . . . "Poddubnaya, L. G." .
