Light and life in the deep sea: Edith Widder

The pioneering marine biologist made it her calling to unravel the secrets of bioluminescence in world's deepest oceans. Bioluminescence is light produced by a chemical reaction within a living organism, and it’s more common in those dark depths than you may think.In this episode Edith talks about how she fell in love with the ocean at a young age, her short bout with blindness, which inspired her fascination with light and the moment she spotted a giant squid. This Episode of Talking Australia is hosted by Angela Heathcote (Senior Digital Producer at Australian Geographic) and produced by Ben Kanthak (www.beachshackpodcasts.com).  You can also follow us on Instagram @australiangeographicSee omnystudio.com/listener for privacy information.
