Detailed explanation-1: -The Radiata is a superphylum which includes both the echinoderms and the ctenophores. It is not part of the usual classification system, and is not used by all biologists. The group includes the radially symmetric animals of the Eumetazoa.
Detailed explanation-2: -The animals in this super-phylum all have radial body symmetry, which is where the name ‘Radiata’ comes from. The two phyla that make up Radiata are Ctenophora, which are the comb jellies, and Cnidaria, which are the other jellies, corals, and sea anemones.
Detailed explanation-3: -Two phyla, Cnidaria and Ctenophora, are often considered together as the radiate phyla or Radiata. This classification recognizes a closer relationship between them than with other invertebrate groups and is based on their shared radial symmetry.
