Nomenclator Zoologicus
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).
The following species are recognised in the genus Polycheira:[3]
Polycheira echinata Heding, 1928
Polycheira rufescens (Brandt, 1835)
