| echinobothrium notoguidoi n. sp. (cestoda: diphyllidea) from mustelus schmitti (chondrichthyes: carcharhiniformes) in the argentine sea. | a new cestode, echinobothrium notoguidoi n. sp., is described from the spiral intestine of the shark mustelus schmitti, from coastal waters off mar del plata, argentina. this species is distinguished from all others in the genus by a rostellar armature consisting of 2 apical groups of 31 large hooks each, arranged in 2 rows (16 anterior, 15 posterior) with 13 hooklets per side, a wide corona of 8-11 rows of spines posterior to the rostellum, 8 rows of 24-26 spines on the cephalic peduncle, and 1 ... | 1997 | 9379298 |
| calliobothrium spp. (eucestoda: tetraphyllidea: onchobothriidae) in mustelus schmitti (chondrichthyes: carcharhiniformes) from argentina and uruguay. | three species of calliobothrium inhabit the spiral intestine of mustelus schmitti in argentina and uruguay. calliobothrium verticillatum australis is redescribed and its taxonomic status modified to species as c. australis. calliobothrium barbarae n. sp. can be distinguished from all other species of calliobothrium, which are small bodied, nonlaciniate, and without accessory piece between the bases of axial hook, by worm length, number of segments, cocoon morphology, and hooks shape. calliobothr ... | 2002 | 12537115 |
| heavy metal levels in fish from coastal waters of uruguay. | copper, mercury, and zinc levels were determined in muscle and liver (n = 163) of seven fish species caught in coastal waters off montevideo and piriapolis (control site): odontesthes spp., mugil platanus, micropogonias furnieri, urophycis brasiliensis, cynoscion guatucupa, menticirrhus americanus, and mustelus schmitti. the local population commonly uses these species for consumption. heavy metal concentrations determined in this study were generally below those obtained for fish caught in arge ... | 2005 | 15883670 |
| orygmatobothrium spp. (cestoda: tetraphyllidea) from triakid sharks in argentina: redescription of orygmatobothrium schmitti and description of a new species. | two species of orygmatobothrium were found inhabiting triakid sharks collected from the coast of buenos aires province, argentina. orygmatobothrium schmittii from mustelus schmitti is redescribed, including new information on the microtrich pattern. orygmatobothrium juani n. sp. from mustelus fasciatus can be distinguished from all other species in the genus using the following combination of characters: worm length, number of proglottids, number of testes, testes distribution, size of eggs, orn ... | 2008 | 18576811 |
| eutetrarhynchid trypanorhynchs (cestoda) from elasmobranchs off argentina, including the description of dollfusiella taminii sp. n. and parachristianella damiani sp. n., and amended description of dollfusiella vooremi (são clemente et gomes, 1989). | during a parasitological survey of teleosts and elasmobranchs in the argentine sea, 3 species of eutetrarhynchids were collected from the batoids myliobatis goodei garman and psammobatis bergi marini, and the shark mustelus schmitti springer. the specimens collected from mu. schmitti were identified as dollfusiela vooremi (sπo clemente et gomes, 1989), whereas the specimens from my. goodei and ps. bergi resulted in new species of dollfusiella campbell et beveridge, 1994 and parachristianella dol ... | 2014 | 25549498 |
