shellfish cornucopia

"Marine snails of the genus Xenophora collect shells, rocks, and other debris from their environment. They attach these objects to their shells at intervals during the shell's growth. Sometimes it creates a neat radiating pattern; sometimes the effect is more that of a jumble of debris. The result for us in any case is that their collections become little samplings of a variety of faraway underwater realms."
