性别变化发生在各种植物和动物中。雄性先熟、雌性先熟和双向（或反向）性别变化在鱼类中已有报道。双向性别变化已知在30种来自6个科，但尚未报道在雀鲷（雀鲷科）。我们进行了交配去除实验，使男性/女性只有组中的原始gynous欺骗damselfalus aruanus，生活在低密度条件下的分支型珊瑚。在一个孤立的珊瑚头上的丧偶男性较小的改变性别的女性时，没有女性或青少年移民到珊瑚。需要进行去除雌性的实验来验证其他先雌先熟物种的逆转性别变化。
Sex change occurs in various plants and animals. Protandry, protogyny, and bidirectional (or reversed) sex change have been reported in fish. Bidirectional sex change is known in 30 species from six families, but has not been reported in damselfish (Pomacentridae). We conducted mate-removal experiments to make male/female-only groups in the protogynous humbug damselfishDascyllus aruanus, living on branching-type corals under low-density conditions. The smaller of the widowed males on an isolated coral head changed sex to female when no females or juveniles immigrated onto the coral. Female-removal experiments are needed to verify reversed sex change in other protogynous species.
