Sort out the animals on the basis of their symmetry (radial or bilateral) coelenterates, ctenophores, annelids, arthropods, and echinoderms.
In the case of radial symmetry, an individual’s body can be divided into equal halves by any plans passing through the longitudinal axis.
Examples of Radial symmetry are Coelenterates, Ctenophores, Echinoderms.
In the case of bilateral symmetry, the body can be divided into two halves when the plane passes through the median longitudinal axis.
Examples of Bilateral symmetry are Annelids, Arthropods.
