They are aquatic animals and are mostly found in marine environments, attached to the rocks at the bottom of the ocean. A few species are also found in freshwater habitats. Coelenterates can be found solitarily or in colonies. You can find them sedentary or free swimming.

How do coelenterates move?

Although some, such as the corals and sea whips, are truly sessile, most coelenterates are capable of some form of movement, ranging from creeping on a pedal disc and burrowing to freely swimming. Coelenterates include both marine and freshwater species.

Do coelenterates have a backbone?

All fish are vertebrates, or animals with backbones. Coelenterates are invertebrates. Unlike most fish and other water animals, they do not have fins, legs, or tails.
