The shell of the conch survives compression and three‑point bending due to lath‑like aragonite crystals that form a microlayer.

The conch shell is known for its highly organized shape, but it is not the organization alone that makes these special animals. The shell of a conch has a microstructure made up of a cross-lamellar matrix consisting of lath-like aragonite crystals. It is this structure that creates the hard shell and provides such strong mechanical responses for a shell under compressive forces. In a sea full of predators this shell provides the animal with its only protection. Such unique design would prove useful for materials used in high impact or high compressive situations.
