| 摘 要： | 雌雄同体动物的交配行为和机制具有多样性的特点。利用身型大小与交配之间的关系来推测雌雄同体动物的交配规律是一个重要的手段。瘤背石磺属雌雄同体动物，通过实验室研究观察及数理分析结果显示：瘤背石磺的求偶行为方式是2个或3个个体进行追逐，追逐具有随机性；其交配行为方式较复杂，既存在同型大小个体交配，也有异型大小个体交配，并且小个体更趋向于扮演雄性角色而大个体多扮演雌性角色。瘤背石磺在繁殖季节时会出现多次交配高峰期，在各交配高峰期时，交配形式具有差异，并且瘤背石磺具有发生互惠性交配的条件。

| Abstract: | Onchidium struma is a hermaphrodite.Mating behavior and mechanism of hermaphrodite animals has diversity characteristics.Using the relationship of body size and mating behavior is an important way to speculate mating laws of hermaphrodite animals.By laboratory observations and mathematical analysis,result showed that the courtship behavior of Onchidium struma is two or three individuals to chase randomly.Mating behavior is complex,there has not only the individual of similar body size but also different siz... |
