In which two ways are echinoderms unique
WebIn conclusion, while cnidarians and echinoderms are both classified as animals, there are several ways in which they are distinct from one another. The radial symmetry of their bodies and the rigidity of their exoskeletons are two characteristics that they have in common with one another. WebThe unique glyptocystitoid genus Rhombifera bears ambulacral facets on five radial plates, which alternate with five orals. The oral area of Lysocystites (blastoid sensu lato) is very similar, which suggests that rhombiferan radials are homologous with “ambulacrals” of Lysocystites and hence with blastoid lancet plates.
