We're doing a bonus episode as we wait for an exciting special guest to return from Russia to talk to us about blue whales. Jaguar and Grady deliver a spooky mystery about underwater giants that kept washing up on shore with one important thing missing - their livers. Who was the culprit and who was the victim? We discuss in an orca versus great white shark showdown! Who do you think will win?  Also, no creature quiz this time. Instead, send up a picture or tell us about or show us your "who would win" battle. Send it to coolfactsaboutanimals@gmail.com, or tweet it to us at @coolanimalspod and we will send you a magnet. Stay tuned for our blue whale episode with our special guest - we can't wait!
