Jul 25, 2026 · 1h 8m
Summary
Hosts Alicia and Christopher White interview marine biologist Steve Haddock about his book, The Radiant Sea, which explores deep-sea organisms' optical adaptations like bioluminescence and transparency. Haddock discusses the technological advancements in underwater imaging and genomics that enable these studies, highlighting how living specimens reveal behaviors lost in dead samples. The conversation covers the evolutionary costs of these traits, their biomedical applications like GFP, and the mysterious functions of phenomena such as disco clam displays.
