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.
This phylum is further divides into three classes:
Q: In which phylum, do organisms have nematocysts. Explain their significance.
Ans: Nematocysts are found in the organisms belonging to Phylum Coelenterata. They are, microscopic stinging structures that are present in the tentacles. Their primary use is to capture and paralyze prey such as fishes and marine animals.
Q: Are coelenterates diploblastic or triploblastic?
Ans: Coelenterates have two layers of cells, ectoderm and endoderm. Hence they are diploblastic.
