| effects of venom of the olive sea snake, aipysurus laevis, on the behaviour and ventilation of three species of prey fish. | venom from the olive sea snake, aipysurus laevis, was injected into three species of prey fish, chromis nitida, dascyllus aruanus and istiblennius meleagris. their behaviour and ventilatory patterns were observed for 48 hr. six progressive stages of envenomation, involving impairment of the locomotory and ventilatory systems, were identified. there were significant interspecific differences in time taken to reach various stages. in nature, the action of the venom not only would facilitate subdui ... | 1990 | 2089740 |
| dynamics of the interaction between the parasitic isopod, anilocra pomacentri, and the coral reef fish, chromis nitida. | field and laboratory investigations into the effect of the parasitic isopod anilocra pomacentri (cymothoidae) on the population dynamics of the reef fish chromis nitida (pomacentridae) were carried out at heron island, great barrier reef, australia. fish carried a single adult parasite just posterior and dorsal to the eye either to the right or to the left of the midline. the adult parasite was overdispersed among fish on patch reefs (dispersion factor, k = 0.69). sequential field observations o ... | 1994 | 7970888 |
