Oysters, mussels, scallops and more. When we pick up shells on the beach, how often do we consider that they represent a life lived, out in the ocean? The dynamic lives of these creatures are easily forgotten, obfuscated by the shell as a decorative object and the shellfish as a commodity. In this episode, we learn how these animals live, what they are, and what challenges they face. Tom speaks with ocean and climate scientist Priya Shukla, to discover the fascinating lives that hide behind that general label: ´shellfish´.
