摘　　要：运用电子显微镜技术和细胞化学方法对秀丽白虾精子进行了形态和超微结构研究。结果发现 ,秀丽白虾精荚中有形似外翻伞状的成熟精子。精子主体部凸面伸出长约 6～ 7μm的单个棘突 ,主体部基部为非电子致密的均匀核 ,核膜呈半解体状态 ,帽状体中有约 2 0根放射状纤丝和大量内含电子致密基质的膜泡。棘突和帽状体构成顶体复合体 ,成熟精子中未发现中心体。The morphology and ultrastructrue of the sperm of the freshwater shrimp, Exopalaemon modestus, were studied with electron microscopy and cytochemical methods. The results show that spermatophors from male Exopalaemon modestus contain mature sperms, which resemble everted umbrellas.A single 6～7*!μm spike extends from the convex side of the main body of the sperm. A decondensed nuclear is housed in the base of the main body. The cap-shaped body contains about twenty radial fibrils and lots of membrane vesicular with electric dense material in it. The cap-shaped body and spike comprise the acrosome complex. The cytoplasm of mature sperm is devoid of centrioles.
