Both eumetazoa and parazoa have distinct cell types forming tissues and possess ectoderm and endoderm. Some type of symmetry and a body plan also distinguish eumetazoa from parazoa. The polyp and medusa body forms and organs are specific to cnidarians, a group within eumetazoa, and do not distinguish eumetazoa as a whole from parazoa.
