Polycheira Explained

Polycheira is a genus of holothurians (sea cucumbers) found in tropical Indo-Pacific.

A curious pattern of reproduction has been found in Polycheira rufescens where specimens change their sex from male to female and from female to male in a reproductive season[1]

The following species are recognised in the genus Polycheira:[3]
