Mollusk

A mollusk, also spelled mollusc, is any soft-bodied invertebrate animal belonging to the phylum Mollusca, typically encased in a calcareous shell. This diverse group includes snails, clams, oysters, squids, and octopuses. Mollusks are characterized by a mantle, which secretes the shell; a muscular foot used for locomotion; and a visceral mass containing the digestive, reproductive, and respiratory organs. They exhibit a wide range of adaptations to diverse environments, from marine and freshwater habitats to terrestrial settings. Their ecological roles are significant, encompassing filter-feeding, grazing, predation, and serving as a food source for other animals. The fossil record indicates mollusks have existed since the Cambrian period, making them one of the most ancient animal groups.
