Ultrastructural observations of the attachment organs of the monogenean Rajonchocotyle emarginata (Olsson, 1876) (Polyopisthocotylea: Hexabothriidae), a gill parasite of rays

Parasitology Research, 2016
The present study uses scanning and transmission electron microscopical observations to examine the haptoral features of the hexabothriid polyopisthocotylean monogenean Rajonchocotyle emarginata from the gills of the elasmobranch Amblyraja radiata. The haptor possesses six equal, pedunculate suckers, each armed with a large, curved, hooked sclerite ...

Ultrastructure of the surface structures of Allodiscocotyla diacanthi (Polyopisthocotylea: Monogenea) from the gills of the marine teleost fish, Scomberoides tol

International Journal for Parasitology, 1995
Scanning and transmission electron microscopic studies have been made of the surface architecture of the fish-gill parasite, Allodiscocotyla diacanthi. Observations of the haptor region have revealed the presence of cushion-like supports at the base of each clamp, together with a pair of anchor-hooks.

Complement to the anatomy of the oncomiracidium ofSerranicotyle labracis (Van Beneden and Hesse 1863) (Monogenea, Polyopisthocotylea)

Parasitology Research, 1989
This report describes the morphology and points out the originality of the osmoregulatory system of the oncomiracidium ofSerranicotyle labracis (Van Beneden and Hesse 1863) Maillard, Euzet and Silan, 1988 (Microcotylidae) among Polyopisthocotylea (Monogenea).

Ultrastructure of spermiogenesis, spermatozoa and the tegument in Atriaster sp. (Platyhelminthes, Monogenea, Polyopisthocotylea, Microcotylidae)

Zoologica Scripta, 1992
Atriaster (Atriaster) sp., a gill parasite in the fish Diplodus cervinus caught near Dakar, Senegal, was studied by transmission electron microscopy. Spermiogenesis is similar to the general scheme in the Cercomeridae and particularly the polyopisthocotylean monogeneans, but shows two remarkable characteristics: (a) the zone of differentiation for ...

Ultrastructure of the Pharynx and Some Parenchyma Cells of Zeuxapta-Seriolae and Paramicrocotyloides-Reticularis (Monogenea, Polyopisthocotylea, Microcotylidae)

Australian Journal of Zoology, 1986
The ultrastructure of the pharynx of Zeuxapta seriolae and Paramicrocotyloides reticularis (Monogenea : Microcotylidae) is described. The pharynx of both species is surrounded by a thick sheath resembling a basal lamina. It contains layers of longitudinal, circular and radial muscles, glandular cells, smaller cells interpreted as connective tissue ...
