Buried in the sand during daytime and crawls on the sand to search for food at night. Feeds primarily on bivalves and gastropods and other small invertebrates buried in the sand (Ref. 800).

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.
