背景资料。关于硬骨鱼精子形态的现有数据显示出很大的差异。本文对软骨类鱼类西伯利亚鲟鱼(Acipenser baerii Brandt，1869)的精子进行了观察。与硬骨鱼相比，软骨鱼精子的头部具有明显的顶体，而其他结构，如中段和单个鞭毛，存在于大多数物种的精子中。
Background information. Available data concerning the sperm morphology of teleost fishes demonstrate wide variation. In the present study, the spermatozoa of Siberian sturgeon (Acipenser baerii Brandt, 1869), a chondrostean fish, was investigated. In contrast with teleost fish, chondrostean spermatozoa have a head with a distinct acrosome, whereas other structures, such as a midpiece and a single flagellum, are present in spermatozoa of most species.
