LaoSponges are simple, multicellular animals belonging to the phylum Porifera, characterized by their porous bodies and lack of true tissues or organs. Mollusks, on the other hand, are a diverse group of soft-bodied invertebrates belonging to the phylum Mollusca, which includes animals like snails, clams, and octopuses. Mollusks have more complex body structures with distinct organ systems, including a muscular foot, a visceral mass, and a mantle. Additionally, mollusks typically have a hard external shell made of calcium carbonate, which sponges lack.
