Glowing sharks & blue beaches spark curiosity— journey with marine ecophysiologist Dr. Laurent Duchâtelet into the luminous world of ocean bioluminescence. Discover how lantern sharks, dragonfish, plankton and more deploy living light for hunting, hiding and flirting; why wavelengths shift from blue to green to rare red; and how decoding luciferin–luciferase chemistry is powering pollution sensors and cancer diagnostics. Guided by deep-sea ROV footage and decades of lab work, this conversation illuminates 90 independent evolutions of glow, the sport-utility of bio-light, and the urgent need to fund fundamental ocean science before these wonders wink out. If you’ve ever dreamed of swimming through spark-lit surf or marveled at fireflies, this episode reveals the science behind the magic—and what we still don’t know.
