Biology     Glossary (e.g. epibenthic)

Depth information reported for China (Ref. 81187). Size refers to disk diameter (Ref. 87041). Found beneath coral slabs and in holes and crevices. Possesses enlarged, modified, venomous spines (Ref. 800). Subtidal. Association with Ophiomastix scolopendrina may serve as its strategy in obtaining food from the host's arms (Ref. 102356).

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.
