Polycheira
 | This article is an orphan, as no other articles link to it. (February 2009) |
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]
- Polycheira fusca
- Polycheira rufescens (=Chirodota rufescens)
- Polycheira vitiensis
