| 为了更详细地阐述海蜇(Rhopilema esculentum)生活史, 作者应用显微观察和对比分析方法, 对其各阶段的生长特征进行了研究, 继而对已报道的海蜇生活史进行了资料补充。研究结果表明: 根据浮浪幼虫纵轴长度及活力将其分为早期、中期和晚期浮浪幼虫; 在海蜇浮浪幼虫变态附着和足囊萌发过程中, 补充了杯状体发育阶段; 根据伞部中胶层变化、中央口发育状况及棒状附着器的出现与否, 对碟状体至幼蜇的发育阶段进行了重新划分, 将海蜇浮游幼体划分为碟状体、稚蜇和幼蜇3 个阶段。实验结果完善了海蜇早期生活史, 为深入开展海蜇基础生物学和基础生态学研究提供参考。 |

| Abstract: |
| In order to characterize the life history of Rhopilema esculentumin detail, its whole life was restudied by microscopic observation and comparative analysis at different life stages. The results showed that, firstly, the life history of R. esculentum was divided into three stages: early stage, intermediate stage and later stage, according to the changing of vertical-axis length and vigor of planula. Secondly, the scyphostoma stage was observed in the two polyp generation modes, settlement﹠metamorphosis of planula and germination of podocyst. Thirdly, the stages from ephyra to young medusa were redivided into ephyra stage, larva medusa stage and young medusa stage, according to the development of mesogloea, the concrescence of central mouth and the formation of clubbed attachment organ. In this paper, we described an early life history of R. esculentum in detail, which could be helpful to study of its basic biology and basic ecology. |
