Shell Beach is covered for a 60km-long stretch with tiny white shells, to a depth of some seven to ten metres. The effect is brilliant – a long, snow-white beach bordered by aqua blue ocean waters.
The hypersalinated water of L’Haridon Bight in Shark Bay are home to billions of tiny coquina bivalve shells and is known as Shell Beach.

The Cardiid Cockle is particularly tolerant to increased salinity, while many species are not. Its predators, such as the shell drilling gastropods, do not cope well in this environment.This has resulted in the accumulation of millions of these tiny shells along the shore.

About 45km south of Denham Township and on the western side of the peninsula, the coquina bivalve shellfish has no predator. The shell fish have existed in huge numbers for thousands of years, then died natural deaths before being washed ashore.

In days gone by, the mass of shells were sawn into building blocks and used in much the same way as we now use cement building blocks.
