I usually collect opercula on this beach. This is a high energy environment and the gravels are well sorted, so the trick is to find a patch of gravel of about the same size as the opercula, then look for the little white things among the little grey things. My goal is to fill a large vase I have. There weren't very many this time - surprising, as I would have expected the storm to have thrown up lots.
There were many, many little paua shells though. The backdrop here is another piece of giant kelp.
