Summary An invertebrate type of ovulation is described for the first time for an echinoderm. In this echinoderm, which is a crinoid, ovulation is the passage of maturing oocytes through temporary openings in the epithelium lining the ovary. After ovulation, which takes about 1 h, the oocytes lie free in the ovarian lumen; there they quickly finish maturing into ova which are spawned into the sea water.
