Shell Beach, in Western Australia’s Shark Bay, has a unique composition, consisting almost entirely of the white shells of Fragum erugatum, a species of cockle (a bivalve). This cockle thrives here because its predators cannot cope with the high salinity of the seawater. On the foreshore of Shell Beach, the layer of shells reaches a depth of 8–9 m and also forms the sea floor, stretching for hundreds of yards from the shoreline.

That’s right: giant, majestic balls. In the sand. The beach north of Moeraki on New Zealand’s South Island is strewn with large, near-spherical boulders. Their origin is unclear, but the most widely accepted scientific view is that they are mineral consecrations that formed sixty million years ago in mudstones—layers of softer sedimentary rock on the seafloor. These mudstones were later uplifted and now form a cliff at the back of the beach. There, gradual erosion exposes and releases the boulders, which eventually roll down onto the beach. The boulders are up to three meters in diameter and some weigh several tons.
