					Members of the class Holothuroidea are gonochoric and have only one gonad.  Spawning and fertilization are both external and some exhibit brooding.  Life cycle:  Embryos develop into planktotrophic larvae (auricularia) then into doliolaria (barrel-shaped stage) which later metamorphose into juvenile sea cucumbers.
