The free-swimming larvae can travel much greater distances than the bottom-dwelling adults, increasing their range. If the environmental conditions for the adults become bad, the larvae can travel to another area that may be more favorable.
starfish are awesome and this answer is completely wrong, the larvae can swim, hide, eat, grow, and move away from danger.
Many_echinoderms_which_are_bottom_dwellers_as_adults_have_free_swimming_larvae_what_advantage_do_these_larvae_provide_for_echinoderms
Adult echinoderms only have one body opening. Their larvae have two.
Cnidarians are true radially symmetrical animals. They include jellyfish. Echinoderms (like starfish) also display radial symmetry. It is important to note that the larvae of echinoderms are bilaterally symmetrical and that Echinoderms evolved from a bilaterally symmetrical group.
To aid dispersal of their larvae. To avoid desiccation. To provide food for crustaceans. To help stabilize oyster beds. Benthic invertebrates don't produce planktonic larvae.
To move away from being in one concentrated spot; spread outwards.
the same type as blue footed underwater donkeys.
Echinoderms have swimming larvae that are bilaterally symmetrical, with left and right sides, but they do not 'develop into' bottom-living adult echinoderms, which are radially symmetrical, often star-shaped. The juvenile (young adult), radial from the start, grows from a group of stem cells within the larva. It gradually moves to the outside of the larva, and the larva and juvenile develop side-by-side. In most cases, the larva eventually settles and shrivels, and the juvenile crawls away. In one species of starfish, however, the juvenile drops off the swimming larva, which can go on swimming for a further three months.
They are larvae
I'm not entirely sure, but I think that larvae are called 'larvae'.
larvae is the baby of insects, for example, ant larvae, bee larvae, etc. etc.
no, because the larvae ARE the baby
The famous animal the "Porifera", has 6 body openings.
