Fistulicola plicatus (Cestoda) and Tristoma spp. (Trematoda) on Swordfish from the Northwest Atlantic
Data on the incidence, location, and morphology of the scolex of Fistulicola plicatus in 24 specimens of swordfish (Xiphias gladius) from the northwest Atlantic are given. The occurrence of normal scolices in tubular sheaths or bladderlike cysts on the outer surface of the rectum is recorded for the...

| Summary: | Data on the incidence, location, and morphology of the scolex of Fistulicola plicatus in 24 specimens of swordfish (Xiphias gladius) from the northwest Atlantic are given. The occurrence of normal scolices in tubular sheaths or bladderlike cysts on the outer surface of the rectum is recorded for the first time for this species. The incidence and location on the gills of Tristoma coccineum and T. integrum are given and the possibility of using these monogenetic trematodes as biological tags is discussed. The increase in the number of dorsomarginal rows of comb teeth with body length for immature specimens of T. coccineum is demonstrated. |
