Question

How are coelenterates different from sponges?​

Answer 1

Answer:

The phylum is named for the many pores that cover the body of a sponge. Coelenterates are members of phylum Coelenterata (phylum Cnidaria is also used). Hydras, jellyfish, and sea corals are types of coelenterates. Sponges have no true tissues or organs, no digestive tract, and no nervous system.

Answer 2

Answer:

Sponges are sessile metazoans, which lack body symmetry. ... The key difference between Porifera and Coelenterata is that Porifera consist of numerous pores throughout the body, working as water intake and outlet openings whereas Coelenterata consist of a single opening on the body working as mouth/anus.
