HERE IS YOUR ANSWER

Cnidaria and Ctenophora are two phyla containing coelenterates with a hollow gut. Both cnidarians and ctenophores are diploblastic animals. The internal body cavity serves as the gut. The gut is covered by a tissue called gastroderm. A single opening serves as both mouth and the anus in cnidarians. However, ctenophores contain a complete digestive system. Tentacles occur around the mouth of both cnidarians and ctenophores. Hydra and jellyfish are cnidarians. The comb jellies are ctenophores. The cnidarians can be either sessile or mobile. But, ctenophores are always mobile. The main differencebetween Cnidaria and Ctenophora is that Cnidaria exhibits radial symmetrywhereas Ctenophora exhibits biradial symmetry. Both cnidarians and ctenophores possess sense organs such as statocytes and ocelli.
