CNIDARIAN RADIAL ASSUMPTION. “Since Cuvier erected the “Radiata” as one of four metazoan “embranchments” cnidarians have generally been described as radially-symmetrical animals. Indeed, many cnidarians exhibit radial symmetry. The body plan of Hydra is a simple cylinder, radially symmetrical about the primary body axis, the oral-aboral axis.”
