• Cnidarians are highly diversified in terms of the number of species compared to ctenophores.
• The body size range is higher among ctenophores than in cnidarians.
• The majority of cnidarians live in the ocean while a very little number of species could be found in freshwater, whereas all the ctenophores have been recorded only from the saltwater environments.
• Cnidarians are radially symmetrical while ctenophores are either radial or biradial in their body symmetry.
• The alteration of generations is present among cnidarians but not in ctenophores.
• Cnidarians have Cnidocytes to disable the prey while ctenophores have colloblasts to capture prey.
• Bioluminescence is more common among ctenophores than in cnidarians.
• Digestive tract is complete in ctenophores but not in cnidarians.
• Ctenophores have a comb plate but never in cnidarians.
