Some brood their eggs and young; nonbrooders may release into the water as many as 2.5 million eggs at a time (see video of sea star life cycle). 99. Life cycle: Embryos hatch into planktonic larvae and later metamorphose into pentamorous juveniles which develop into young sea stars with stubby arms (Ref. If a male and female release gametes in close proximity, the eggs are fertilized. Free returns. 1997. The Animal Diversity Web team is excited to announce ADW Pocket Guides! 600 results for sea cycle. During fragmentation, it can also regenerate a completely new starfish from just about any piece of its body that brakes off, when this happens the arm looks like a long stick with a star attached to the end - and are called comets. The microscopic larvae resulting from sexual reproduction begin to grow and, within several months, look like adult sea stars. Like other seastars, the blue seastar can use autonomy, or self-severance of a limb, to escape predation. The exact lifetime of a star depends very much on its size. The swimming embryos are animals that eventually metamorphose, settle to the floor of an ocean area and develop into adults. A bright red or orange "eye" spot appears in the center of its body. They are popular among tourists and in the aquatic life industry. Topics The lar­vae spend about 28-30 days in the water col­umn be­fore set­tling onto a hard sur­face on the reef and meta­mor­phos­ing into a tiny ver­sion of the adult star.
