Maturity: Lm ? range ? - ? cm
Maximum depth from Ref. 130839. Observed on subtidal rock, subtidal sand, coral reefs, artificial structures (Ref. 102838), sand tidal flat, rock tidal flat, rock, and sand beach (Ref. 130839). Common among sessile macroinvertebrate colonies, such as on sponges Aplysinella rhax, in crevices and in the open. Epizoic on sponges (Ref. 107862). Sponge-associated detritivore (Ref. 108144).
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.
