Shell Beach (Western Australia)
Situated on the northeastern side of the Taillefer Isthmus along the L'Haridon Bight, the beach is covered with shells for a 60 km (37 mi) stretch to a depth of 7–10 m (23–33 ft). It is one of only two beaches in the world made entirely from shells.
The beach was named because of the great abundance of the shells of the cockle species Fragum erugatum. The seawater in the L'Haridon Bight has a high salinity due to both the geomorphology and local climate of the area. This high salinity has allowed the cockle to proliferate unchecked, since its natural predators have not adapted well to this environment.
