The Glow Below
Host Molly Webster talks with deep-sea explorer and oceanographer Edie Witter about her decades studying bioluminescence in the deep ocean. Witter describes her first encounters with glowing deep-sea creatures, the many survival functions of bioluminescence, and the surprising evolutionary origin of light-producing bacteria. The conversation explores how light operates as camouflage, weapon, and communication system in the deep sea, and how interacting with bioluminescent life can profoundly affect human perception and awe.
