Found the hermit crab on the beach in St. George. They’ll use almost anything for a shell. It turns out that they follow a fashion cycle just like us. As they grow, they get bigger shells. How they choose depends on supply. A few years ago there was a shortage of shells. Good for the shells’ owners. Bad for the hermit crab population. This year a spiky spiral shell was in abundance, so that’s what they were all wearing on St. George Island. Mine, however, shopped on Madison Avenue for her fine urchin skirt.
