Detailed explanation-1: -Complete Answer:-The cnidarians and the echinoderms possess the radial symmetry.
Detailed explanation-2: -Radial Symmetry This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies).
Detailed explanation-3: -Radial Symmetry: Unlike chordates, like humans or sharks, echinoderms possess a radially symmetrical body plan. In almost all situations involving echinoderms, the species exhibits pentamerous radial symmetry (pentaradial), or five sided radial symmetry.
Detailed explanation-4: -Final answer: Body symmetry in Echinodermata is radial.
Detailed explanation-5: -For example, pies, snowflakes, and starfish are radially symmetric because they have many different lines of symmetry (dividing them into matching halves) and the lines cross one another at the center.
