We observed the surface structure and inner structure of the compound eyes . and we also studied the change process of the ultrastructure of the compound eyes in different light adaptation . comparative studies on the structure differences of photoreceptor between portunus tritubereulatus and metapenaeusensis were also done 运用电子显微镜技术观察了三疣梭子蟹( portunustritubereulatus )的光感受器的超微结构,对三疣梭子蟹复眼的外部形态、大小、内部超微结构,以及在不同光适应条件下的变化过程进行了研究;并且与刀额新对虾( metapenaeusensis )光感受器的超微结构进行了比较。
