Biology     Glossary (e.g. epibenthic)

This is an epibenthic species found in coral reefs at depths of 20 to 40 m (Ref. 83942). Also on rubble (Ref. 111335).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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.
