The Cage

This is episode two of Swimming with Shadows: A Radiolab Week of Sharks. Jaws spawned a thousand imitators: sharks in tornados, sharks in avalanches, sharks that battle giant octopuses. Hollywood has officially turned sharks into monsters of every shape and size. And yet, somehow, there will always be more. But drop below the surface, into the cold, quiet blue, and another creature appears. One that has survived mass extinctions, outlasted ancient predators and pre-dates Mount Everest, the existence of trees, even the rings of Saturn. A shark that is somehow even more remarkable than sharks in tornadoes. Today, we go visit that shark. Special thanks to Andrew Fox, the entire team at Rodney Fox Shark Expeditions, John Long whose book The Secret History of Sharks inspired our obsession with sharks, and Greg Skomal, whose wonderful new book on his life studying white sharks is Chasing Shadows: My Life Tracking the Great White Shark.EPISODE CREDITS: Reported by - Rachael Cusickwith help from - Pat WaltersProduced by - Rachael Cusick and Simon Adlerwith help from - Pat WaltersSound design contributed by - Jeremy Bloomwith mixing help from - Jeremy BloomFact-checking by - Natalie Middletonand Edited by  - Pat Walters EPISODE CITATIONS:Videos - Loved learning about all the different kinds of sharks there are?
