Ben Garrod uncovers the secrets of how vertebrates capture and devour their food using extreme jaws, bizarre teeth and specialized bony tools. He takes a cherry picker up a giant sperm whale's jaw, finds out which animal has teeth weighing five kilos each and which uses its skull as a suction pump. Ben gets his own skull scanned and 3D printed to discover how diet in humans isn't just affecting our waistlines but is also changing the shape of our bones.
