A mollusk is typically covered by a hard, calcareous shell made primarily of calcium carbonate. This shell serves as protection against predators and environmental hazards. In some mollusks, like octopuses and squids, the shell may be internal or absent altogether, with their bodies instead having other adaptations for protection and mobility.
