摘　　要：实验研究红鳍东方精子形态的超微结构：红鳍东方精子分头部和尾部等两部分。头部似炮弹状，无顶体；核内有空隙，空隙中有或无少量电子致密小颗粒；细胞膜与核膜间的原生质有向外鼓起的单个小液泡；中心粒复合体位于植入窝内，由近端中心粒、中心粒间体和基体等组成。袖套位于核后端，内含７～８个环列的线粒体球。尾部近核端部分鞭毛的一侧有小囊泡群聚的囊泡鞘；远核端部分有侧鳍；囊泡鞘和侧鳍与轴丝的中央微管同在“Ｙ”轴上；轴丝为“９＋２”结构。The spermatozoon of ocellate pyffer or tiger puffer (Takifugu rubripes) consists of head, midpiece and tail. The head, without apical body, is shell shaped, whose nucleus is the main part in which there are some small gaps with a small amount of fine and close granulas. There is cytoplasm between the cell membrane and the nucleus, with vacuoles bulging outward. The centriolar compound of midpiece is situated in the implantation fossa which consists of three parts: the proximal centriole, the intercentriolar and basal body. The sleeve is behind the nucleus which contains seven to eight mitochondria arranged in a circle. The flagella at the proximal end of the nucleus of the tail protrude from the central space of the sleeve and there is a projected vesicle sheath forming with collected vesicles at the side of the flagella. The lateral fin of the tail rises at the distal end of the nucleus. The cross axis and the central microtubule of the axoneme of the vesicle sheath and lateral fin are situated in the Y axis together. The axoneme of the tail is typical in structure and is of the 9+2 model.
