Four phyla of invertebrates include Porifera (sponges), Cnidaria (jellyfish, corals, and sea anemones), Mollusca (snails, clams, and octopuses), and Arthropoda (insects, arachnids, and crustaceans). These phyla encompass a diverse range of organisms with varying characteristics and habitats. Each phylum plays a crucial role in their respective ecosystems.
