| hatching rhythms in the the capsalid monogeneans benedenia lutjani from the skin and b. rohdei from the gills of lutjanus carponotatus at heron island, queensland, australia. | spontaneous hatching of eggs of benedenia lutjani and b. rohdei occurred after incubation for 4-6 days and 6-10 days, respectively, at a constant temperature in the range 22-28 degrees c when exposed to natural illumination or to alternating 12-h periods of light and darkness (ld12:12; light on, 06.00 h; light off, 18.00 h). under these conditions, hatching of the eggs of both species was rhythmical, all larvae emerging only during periods of illumination. hatching was not confined to particular ... | 1996 | 9024862 |
| migration, site-specificity and development of benedenia lutjani (monogenea: capsalidae) on the surface of its host, lutjanus carponotatus (pisces: lutjanidae). | life-history attributes of the capsalid monogenean benedenia lutjani, a parasite of lutjanus carponotatus from the great barrier reef, queensland, australia, were investigated from experimental infections. oncomiracidia of b. lutjani invaded and attached at any site on the fish, but more commonly invaded body surfaces. immature specimens then migrated to the pelvic fins. development of the reproductive organs of b. lutjani corresponded with migratory movements on the host. parasite aggregation o ... | 2002 | 12003066 |
| a new genus and species of cryptogonimid from lutjanus spp. (pisces: lutjanidae) on the great barrier reef and new caledonia. | lobosorchis tibaldiae n. gen. and n. sp. (digenea: cryptogonimidae) is described from the intestine, pyloric ceca, and rectum of 2 species of lutjanus (pisces: lutjanidae), lutjanus carponotatus and lutjanus fulviflamma, from the great barrier reef, queensland, australia, and new caledonia. the genus is tentatively placed in the neochasminae and is distinguished within the cryptogonimidae by the combination of follicular testes, oral spines, and vitelline follicles restricted to the anterior reg ... | 2005 | 17089765 |
