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.
