Like so many beachcombers, I am an equal opportunity collector. Even when my focus should be on searching for sea glass, I find myself picking up other interesting items of desire: shells, driftwood, old spark plugs and interesting rocks.
So when I came across this Facebook post about a rock with a hole all the way through it, I had to find out more!
I have found a number of these rocks but imagined that they were simply an anomaly, a one-off, a peculiar oddity.
But now I know differently. The hole in the rock is bored by a bivalve (similar to a clam) called a Piddock, conveniently equipped with a sharp edged shell that can excavate a hole in a rock, where it then settles in and makes its home, living happily as a clam ever after! And now you know!
