The platyctenid Coeloplana gonoctena is protandrous (151) and probably is a true sex changer. Females are larger than males and are found only at the end of summer, while males are found all year.

Other members of the genus are cosexual.1982, David Policansky, “Sex change in plants and animals”, in Annual Review of Ecology and Systematics, volume 13, number 1, →JSTOR, pages 471–495:
