Size refers to disc diameter (Ref. 87041). Occurs in small crevices or under stones on reef platform and in shallow intertidal area (Ref. 800). On inner reef flats, extending its arms from crevices and from under rubble (Ref. 97449). Feeds on detritus (Ref. 800) and neuston (Ref. 102356). May be a deposit feeder or suspension feeder (Ref. 102356). 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 (Ref. 833).
