The process of spermiation in the ratfish Hydrolagus colliei is described and compared with that in mammals and amphibians. Spermiation in this species involves prior fluid space expansion both within the apical parts of the Sertoli cytoplasm and in the spaces between Sertoli cells and spermatids. The apical ends of Sertoli cells fragment, including the parts immediately around the spermatid acrosomes. Intercellular material between the spermatid tips and the Sertoli cells dissolves. Concurrently an opening from the seminiferous follicle into the efferent ductule is made by means of changes in cell shape and separation of Sertoli cells and efferent ductule cells that adhere to each other up to the time of sperm release.
描述了银鲛（Hydrolagus colliei）的精子释放过程，并将其与哺乳动物和两栖动物的精子释放过程进行了比较。该物种的精子释放过程包括在支持细胞细胞质顶端部分以及支持细胞与精子细胞之间的空间内预先进行的液体空间扩张。支持细胞的顶端部分破碎，包括紧邻精子顶体的部分。精子细胞顶端与支持细胞之间的细胞间物质溶解。同时，通过细胞形状的变化以及支持细胞与直到精子释放时一直相互粘连的输出小管细胞的分离，形成了从生精滤泡到输出小管的开口。
