Mindless prehistoric killers from the deep or slick sophisticated predators? Sharks are responsible for fewer than 10 deaths per year, so why are we so terrified of them? This programme celebrates the extraordinary array of senses and skills that have evolved over 400 million years, allowing the shark to roam not just across the tropics, but as far as the upper reaches of the Amazon and under the arctic ice! Through 8 sharks, filmed as far apart as Hawaii, Australia, South Africa and Greenland, we will change your perceptions for ever!

Natural World is a nature documentary television series broadcast annually on BBC Two and regarded by the BBC as its flagship natural history brand. It is currently the longest-running series in its genre on British television, with more than 400 episodes broadcast since its inception in 1983. Natural World is produced by the BBC Natural History Unit in Bristol, but individual programmes can be in-house productions, collaborative productions with other broadcasters or films made and distributed by independent production companies and purchased by the BBC. Natural World programmes are often broadcast as PBS Nature episodes in the USA. Since 2008, most Natural World programmes have been shot and broadcast in high definition.
