The ocean's deadliest predators often eat more than just sardines and seals. Their boundless hunger and curiousity can lead sharks to chow down on the most unexpected things. Deep dive into the fascinating science of an underwater world where nothing is off the menu, whether it's big game like hippos, crocs and humans, or inanimate objects like kayaks, cages and chicken coops. Sharks That Eat Everything, part of Sharkfest, tonight at 9pm, on National Geographic WILD UK. | National Geographic UK
