This study reports the parasites found in the stomach of five individuals of swordfish, collected off the central-south coast of Chile during 2011. A total of 3,936 parasites was found; a few (n= 14) were cestodes (Tentacularia coryphaenae Bosc, 1797), while most (n= 3,922) were nematodes (Hyterothylacium spp.). Only some of the nematodes were identified as H. incurvum (= Maricostula incurva Bruce & Canon 1989). These parasitological findings are not new, however, the great abundance, the different developmental stages, and the fact that several nematode larvae were attached to muscles and scales of the fish prey (Cubiceps sp.), allow us to suggest that this fish is the intermediate host for Hyterothylacium spp. The cephalopods (e.g. Dosidicus gigas which was another prey item) might transmit larval cestodes to the swordfish.
