| Abstract: | The ultrastructure of the spermatozoon of Didimarca tenebrica is observed using the transmission electronic microscope. The mature spermatozoon consists of two parts, i.e., a head and a tail. The head is formed by an acrosome and a nucleus. The contents in the cone-shaped acrosome is homogeneous, and the subacrosomal space is filled with granular materials. The cylindrical nucleus is highly condensed. Unlike the front nuclear pocket, the posterior nuclear pocket can be observed in necleus. The tail is composed of a short mid-piece and a flagellar-shaped end-piece. Four round-shaped mitochondria and a distal centriole make up the mid-piece. The end-piece consists of an axoneme and its surrounding plasma membrane. The axoneme has a typical 9+2 structure |
