What is a mollucus?

Answer 1

Mollusks, or mollusca, are a diverse group of invertebrate animals that includes snails, clams, octopuses, and squid. They are characterized by a soft body, which is often protected by a hard shell made of calcium carbonate. Mollusks are found in a variety of environments, from deep oceans to freshwater and terrestrial habitats, and they play important ecological roles as herbivores, predators, and scavengers. This phylum includes some of the most complex and intelligent invertebrates, particularly among cephalopods like octopuses.
