WebReproduction: The digestive system of Ctenophores: General characteristics of ctenophores: In Ctenophores Eumetazoans, biradial symmetry is present it posses features of both radial and bilateral symmetry. The gastrovascular canals branchings have bilateral symmetry while the radial symmetry comes from the comb plate arrangement. WebEchinoderm larvae are initially bilaterally symmetrical, but later as adults develop radial symmetry; Cnidarians are radially symmetrical; ctenophores are biradially symmetrical; and sponges have no symmetry. Animal phyla appeared in the fossil record as marine species during the Cambrian explosion, about 542 million years ago.
