Most of the cultural values associated with conch shells come from the shells superior strength. These shells grow fast, spirally out and getting more prominent as the snail ages. Seashells are not grouped by or classified for the shells themselves. However, some have a very strong foot and can attach themselves to hard surfaces like rocks.

They feed on small invertebrates. As it grows bigger, a mollusc uses its soft body tissue (the mantle) to lay down more layers of shell made chiefly of calcium carbonate, the same chalky material as a hens eggshell.
