Seashells

Misha Glenny and guests discuss a familiar feature of our beaches: seashells, from their astonishing shapes and patterns that teach us about Earth’s oceans, to the ways that humans have treasured shells throughout history. Seashells appear in the mythologies of countless cultures across the world - think of Botticelli’s Venus emerging from a giant scallop shell, Vishnu's sacred horn panchajanya, or the Aztec god Quetzalcōātl’s talisman cut from a conch shell. The urge to collect shells seems to be as old as our species. We’ve used them as decoration, currency, and musical instruments. But shells aren’t just beautiful objects washed up on our beaches. Many belong to one of the most diverse groups of the animal kingdom, Mollusca, and the remarkable morphology of forms and structures they grow in offer insight into the past, present, and future of the marine world.
