Sir can you please tell about phylum coelenterata
These are typically invertebrate animals, which show a very simple level tissue organisation. 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.
Coelenterates can be called as the simplest animal group that has true tissue's and have the characteristic coelenteron or the gastrovascular cavity.
