Description | Using scanning electron microscopy (SEM), the external morphology of all developmental stages (egg, oncomiracidium, diporpa, just fused juvenile and adult) of parasite Eudiplozoon nipponicum (Monogenea, Diplozoidae) from the gills of carp was studied. During the ontogeny, the tegument, tegumentary and sensory structures are subsequently developed. Attachment apparatus starts to form from the oncomiracidium stage onwards. Further developmental stages are adapted to the environment of the gills. In connection with reproductive strategy, the two morphological structures of diporpa (ventral sucker and dorsal papilla) appear to play important role. On the gills, two individuals need to meet and these structures mediate the fusion between two diporpae. The hindbody of adult parasite is highly modified to the attachment. The haptor, folds and lobular extensions are most developed. The forebody is flexible and enable to interact with host gill tissue. The process of food intake of parasite was discussed. |
