					Members of the class Crinoidea are gonochoric.  During spawning, the pinnule walls rupture and the eggs and sperms are shed into the seawater.  Life cycle:  Embryos elongate into free-swimming larvae (doliolaria) which later sink to the bottom where they metamorphose into stalked sessile crinoid.
