Polycheira

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]

Systematics

Polycheira appear to be closely related to the genus Chiridota (both belong to the subfamily Chiridotinae).[2] The type species of the genus is Polycheira rufescens (Brandt, 1835).

Species include:[3]
