Biology     Glossary (e.g. epibenthic)

Commonly found at depth >30 m, in fine sand sediments (Ref. 96521). Free-living (Ref. 3123). A mobile suspension feeder (Refs. 95752, 96501). When feeding, its disc is buried 4 to 8 cm below the sediment surface, while its two arms are extended into the column (Ref. 113568).

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

Members of the class Ophiuroidea are mostly gonochoric, others are protandric. Fertilization is external. Brooding is common, bursae is used as brood chambers where the embryos develop into juveniles and later crawl out from the bursal slits. Life cycle: Embryos hatch into free-swimming planktotrophic larvae and later metamorphose into tiny brittle stars which sink down the bottom where they grow into adult form.
