Size refers to disc diameter (Ref. 87041). Found on rock pools, fringing reefs, eelgrass and dead corals (Ref. 87041). Abyssal (Ref. 88950). Solitary. Abundant under Porites lobata, among rocks and boulders on reef-rock substrate. Also in midreef to shallow subtidal corals adjacent to a lagoon. Occupies narrow crevices (Ref. 102358).
Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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.
