(Secret Life of Crocodiles With Ben Fogle/2012) Crocodiles are the world’s most dangerous predators, responsible for the deaths of a thousand people a year. Efforts to combat crocodile attacks are hampered by how little is known about the formidable creatures, as they spend 80% of their time hidden underwater. Now groundbreaking researchers in Botswana are investigating the secret world of these notorious killers. Incredibly they are scuba diving with them, gaining invaluable insights into their lives and behaviour as well as stunning underwater footage. Environmentalist and wildlife ambassador Ben Fogle joins them for a nervewracking dive with Nile crocodiles in Africa before repeating the experience in Australia as researchers transport their methods there.
