Question

Write two characteristic features of Coelenterata platyhelminthes and Mamarhelmintiws

Answer 1

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 tissues and have the characteristic coelenteron or the gastrovascular cavity.
