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 one of Swimming with Shadows: A Radiolab Week of Sharks.
Rodney Fox went into the ocean one summer day in 1963. He came out barely alive, his body torn apart by a great white shark. At the time, it was one of the worst shark attacks ever survived.
After he recovered, he was pulled back into the shadowy world he feared most. Again and again and again. That shark attack left behind a question that still lingers, for Rodney, and for all of us: When you can’t see the thing that scares you, what kind of monster does your mind create? And how do you fight past it?
Special thanks to Surekha Davies, Asa Mittman, Scott Poole, and Maria Tatar.

This is episode three of Swimming with Shadows: A Radiolab Week of Sharks.
Today, we take a trip across the world, from the south coast of Australia to ... Wisconsin. Here, scientists are scouring shark blood to find one of nature’s hidden keys, a molecular superhero that might unlock our ability to cure cancer: shark antibodies. They’re small. They’re flexible. And they can fit into nooks and crannies on tumors that our antibodies can’t.
We journey back 500 million years to the moment sharks got these special powers and head to the underground labs transforming these monsters into healers. Can these animals we fear so much actually save us?
Special thanks to Mike Criscitiello, David Schatz, Mary Rose Madden, Ryan Ogilvie, Margot Wohl, Sofi LaLonde, and Isabelle Bérubé.
