VIABILITY OF SCYPHISTOMAE OF AURELIA sp.1 EXPOSED IN THE AIR
海月水母(Aurelia sp.1)水螅体在空气中暴露存活研究

In the laboratory,the viability of scyphistomae of Aurelia sp.1 being exposed in air and in the seawater by turn are studied.The possibility of living in the intertidal zone was also analyzed.At the exposed 15min group,the viability rates of the scyphistomae are 100% in the experiment.At the exposed 30min group,its viability rate is 82.22% after twenty-fifth hour.At the exposed 45min group,the scyphistomae’s viability rate dramatically falls to 46.67% after twenty-fifth hour.At the exposed 1 hour group,the viability of the scyphistomae drop significantly to 46.67% after the third hour,then they fall to 26.67% after the twenty-fifth hour.At the exposed 2 hour group,the viability of the scyphistomae reduce significantly to 2.38% after 4h,then all the scyphistomae are dead after 8h.The time when half of the scyphistomae died is about 57 minute.According to the results,it is preliminarily presumed that the scyphistomae of Aurelia sp.1 may survive in lower intertidal zone.
