The word seashell is often used to mean only the shell of a marine mollusk. Marine mollusk shells that are familiar to beachcombers and thus most likely to be called "seashells" are the shells of marine species of bivalves (or clams), gastropods (or snails), scaphopods (or tusk shells), polyplacophorans (or chitons), and cephalopods (such as ...

The following is a list of types of seafood. Seafood is any form of sea life regarded as food by humans. It prominently includes shellfish, and roe. Shellfish include various species of molluscs, crustaceans, and echinoderms. In most parts of the world, fish are generally not considered seafood even if they are from the sea.
Mollusc shells (especially those formed by marine species) are very durable and outlast the otherwise soft-bodied animals that produce them by a very long time (sometimes thousands of years even without being fossilized). Most shells of marine molluscs fossilize rather easily, and fossil mollusc shells date all the way back to the Cambrian period.
These are seashells, the shells of various marine mollusks including both gastropod and bivalves. Each one was chosen to represent a maritime state, based on the fact that the species occurs in that state and was considered suitable to represent the state, either because of the species' commercial importance as a local seafood item, or because ...
The shell is coiled, aragonitic, [22] nacreous and pressure-resistant, imploding at a depth of about 800 m (2,600 ft). The nautilus shell is composed of two layers: a matte white outer layer with dark orange stripes, [23] and a striking white iridescent inner layer. The innermost portion of the shell is a pearlescent blue-gray.
The Registry of World Record Size Shells is a conchological work listing the largest (and in some cases smallest) verified shell specimens of various marine molluscan taxa.A successor to the earlier World Size Records of Robert J. L. Wagner and R. Tucker Abbott, it has been published on a semi-regular basis since 1997, changing ownership and publisher a number of times.
