Abstract
A hermaphroditic sea urchin, Strongylocentrotus purpuratus, with three ovotestes and two testes is described. Neither cleaving eggs nor embryos were found in corpore. Fertilization inter se gave normal larvae. The specimen was collected from Palos Verdes, Calif., a region which has yielded an unusually large number of hermaphroditic S. purpuratus.
摘要
描述了一只具有三个卵巢和两个精巢的雌雄同体海胆，Strongylocentrotus purpuratus。在体内既没有发现分裂的卵子也没有发现胚胎。相互受精产生了正常的幼虫。该标本来自加利福尼亚州的帕洛斯弗迪斯，该地区产生了异常数量的雌雄同体 S. purpuratus。
