They may look like crusty little bumps on rocks, but barnacles are anything but ordinary. In this episode, we dive beneath their stony exteriors to uncover a life of surprising complexity. From upside-down shrimp relatives that cement their heads to the seafloor, to parasitic body-snatchers that take over crabs, these tiny creatures defy expectations. You'll discover how barnacles ride whales across oceans, craft one of the strongest natural glues on Earth, and even inspire medical innovation. Join us as we explore the extraordinary world of the seemingly humble barnacle.
