摘要为了获得无性系刺胞动物Zoanthussansibaricus繁殖模式的数据，在2000年4月至2002年3月期间，在樱岛大正熔岩场用水肺装置对水螅体进行了为期24个月的采样（繁殖季节每周采集水螅体）。根据断面形态将虫体分为雄性、雌性和无性三种性型，并在同一群体中发现虫体。在樱岛，山泽珠在7月中旬产卵，释放出卵母细胞和精子。这些产卵事件与月相同步发生。在桑西巴里斯的配子发生中，卵母细胞在二月变得可识别，并从六月底开始迅速生长。精母细胞在6月变得可识别，并在7月中旬迅速成熟。产卵后，仍留在内胚层的卵母细胞很快被吸收到组织中。
Abstract In order to obtain data on the reproductive pattern of the clonal cnidarian Zoanthus sansibaricus, polyps were sampled by scuba gear at Taisho Lava Field, Sakurajima, for 24 months between April 2000 and March 2002 (polyps collected weekly for breeding season). According to cross-sections, Zoanthus polyps were divided into three sexual types; male, female and asexual, and were found in the same colony. At Sakurajima, Zoanthus sansibaricus spawned in the middle of July, releasing oocytes and sperm. These spawning events occur synchronously with moon phase. In gametogenesis of Zoanthus sansibaricus, oocytes became recognizable in February and grew rapidly from the end of June onward. Spermatocytes became recognizable in June and matured rapidly in the middle of July. After spawning events, oocytes still remaining in the endoderm were absorbed into Zoanthus tissue quickly.
