摘　　要：综述了双壳类软体动物精子发生及精子形态结构方面的研究进展。指出双壳类软体动物精子发生过程中精细胞分化具有种、属特异性,精细胞分化的细节是区别个体外部形态很近的物种的依据;精子的形态结构具有种的特征,精子结构的比较研究将成为双壳类软体动物系统演化研究的重要方法之一。The studies on spermatogenesis and morphology of spermatozoa of Bivalvia are reviewed in the present paper. It is pointed out that the characteristics of spermatozoa differentiation are distinct in different genera and species during the spermatogenesis, the details can be used to distinguish species of exterior similarity, and the morphology of sperm has specific characteristics. The comparative study of sperm structure of different species is one of the important methods in the study of the evolutionary biology of Bivalvia.
