Vedclass · Answer

(A) Echinoderms are members of the phylum $Echinodermata$. $1$. They are exclusively marine animals. $2$. They exhibit organ-system level of organization and are triploblastic (possessing three germ layers: ectoderm,mesoderm,and endoderm). $3$. They possess a coelom (coelomate animals). $4$. Adult echinoderms exhibit radial symmetry,while larvae exhibit bilateral symmetry. $5$. They lack a notochord throughout their life cycle,placing them in the group of non-chordates. Therefore,the correct description is that they are triploblastic animals without a notochord.
