The Glow Below

A call to oceanographer Edie Widder about a fish with a very odd immune system quickly becomes something else: a dive into the deep sea, into a world of brilliant light. But down there, the light doesn’t behave like light -- it sparkles and glows, but also drips, squirts, and dribbles. Today, find out how creatures make the light and how they use it, from hunting and hiding to maybe even … talking. And hear about a series of mysterious moments where Edie goes from studying the creatures to becoming one of them. EPISODE CREDITS: Hosted by - Molly WebsterReported by - Molly WebsterProduced by - Maria Paz Gutierrezwith help from - Molly WebsterFact-checking by - Diane A.
