Main Difference – Porifera vs Coelenterata
Both Porifera and Coeleterata are two phyla in the kingdom of Animalia. The animals in the phylum: Porifera are usually called sponges. The animals belonging to the phylum: Coelenterata is identified as Cnidaria. Sponges are sessile metazoans, which lack body symmetry. Some Cnidarians are sessile whereas others are free-swimming. Cnidarians consist of radial 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.
