Environment: milieu / climate zone / depth range / distribution range
Ecology
Reef-associated; depth range 0 - 60 m (Ref. 800). Tropical
Indo-Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 40.0 cm WD male/unsexed; (Ref. 800)
Occurs in shallow reef areas exposed to the sunlight, on rocks, dead coral or rubble at depths of 0 to 60 m (Ref. 800). Also on a reef slope (Ref. 97449); among sponges, macroalgae and seagrasses (Ref. 82802). Juveniles hide under corals and rocks. Feeds on detritus, small invertebrates living on algal mats and dead animals (Ref. 800). Associated with coral communities. Likely feeds on turf algae and bacterial film over hard substrates (Ref. 129602).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Asteroidea exhibit both asexual (regeneration and clonal) and sexual (gonochoric) means of reproduction. Life cycle: Embryos hatch into planktonic larvae and later metamorphose into pentamorous juveniles which develop into young sea stars with stubby arms.
