采用对比实验与显微观察的方法,对海蜇浮浪幼虫及早期螅状体的摄食行为进行了研究。结果表明,海蜇浮浪幼虫期不摄食外界食物;浮浪幼虫附着变态发育成海蜇螅状体1d后,开始摄食其它浮浪幼虫,螅状体发育到第3天摄食能力迅速增强,能够捕食卤虫无节幼体。海蜇早期螅状体的捕食实验结果表明,早期螅状体开始捕食主要受两方面影响,一方面是口的发育,另一方面是刺细胞的发育。 The comparative study and microscopic observation methods were used to study the feeding behavior of larvae and larvae of larvae of jellyfish. The results showed that the floating larvae of jellyfish did not ingest external food. The larvae larvae metamorphosis developed into jellyfish jellyfish 1d, and began to ingest other larvae of larvae. The larvae fed on larvae developed rapidly until day 3, Larvae The experimental results of the prey on the jellyfish in the early stage of jellyfish show that the predation of the early jellyfish is mainly influenced by two aspects, one is the development of the mouth and the other is the development of the stinging cells.
