Mollusk Shell Structure
The structure of mollusk shells refers to the composition, shape, and arrangement of the hard outer covering that encases and protects the soft body of various mollusk species. Mollusk shells are typically composed of calcium carbonate and are secreted by the mantle of the mollusk. The shell can vary in shape, size, color, and texture depending on the species of mollusk. The structure of mollusk shells plays a crucial role in providing protection from predators, maintaining buoyancy, and aiding in locomotion for these aquatic organisms.
