Abstract:

The gonadal and germ cell development of Hemifusus ternatanus was studied by using the tissue sectioning tech-nique. The results showed that H. ternatanus was sexually dioecious. Spermary was of multi-branched tubular structure, con-sisting of spermatogenic and seminiferous tubules. The development of spermary was divided into four stages, namely prolif-erating stage, growing stage, maturing stage and resting stage. Spermatogonia adjoined to the basal membrane of spermato-genic tubules. Spermatogenic cells that lay in varying developmental phases were sequentially arranged from basal membrane to tubular lumen, including primary spermatocytes, secondary spermatocytes, spermatozoa, and sperm. Spermary could be sexually matured and released in a repeated way. According to the size of germ cells and yolk granules, the ovarian develop-ment of H. ternatanus could be divided into the following three stages: proliferating stage, growing stage and maturing stage. Based on the change in follicle size, structure, and contents, ovarian development was divided into proliferating, growing ma-turing, spawning and resting stages. In addition, sex reversal phenomenon in H. ternatanus was discussed in this paper.
