Question

Quizplus · Accepted Answer

Larval echinoderms exhibit bilateral symmetry, which becomes radial symmetry as they mature into adult forms. Spiral cleavage is a characteristic of early embryonic development in certain groups of animals, but not echinoderms. Gastrovascular cavity is found in animals such as cnidarians, while exoskeleton is a characteristic of some groups of arthropods and mollusks. Lophophore is found in certain groups of invertebrates such as bryozoans and phoronids, but not echinoderms.
