据推测，鸭嘴兽（Platycephalidae）经历了四个阶段，因此性别变化了三次：第一个雄性阶段，第一个雌性阶段，第二次雄性阶段和第二次雌性阶段。在本研究中，雄性和雌性的性腺分别由发育的睾丸和未成熟的卵巢和仅卵母细胞构建。在这项研究中，女性的体型明显大于男性。在假设的第一雌性期的大小范围内没有雌性。在任何其他研究中都没有报道过雌雄同体鱼类的性别逆转。因此，假设的第一个雌性阶段的标本可能不同于。meerdervoortii。因此，这个物种应该被认为是不变性的原雄性。
Suggrundus meerdervoortii(Platycephalidae) has been hypothesized to pass through four phases, thus changing sex three times: the first male, first female, second male and second female phases. In this study, gonads of males and females were constructed from developed testis with an immature ovary and only oocytes, respectively. The females in this study were significantly larger than the males. There was no female in the size range of the hypothesized first female phase. Reversed sex change among protandrous fishes has not been reported in any other studies. Thus, the specimens of the hypothesized first female phase may be different fromS. meerdervoortii. Therefore, this species should be considered protandrous without reversed sex change.
