Adventurer Ben Fogle set off from Clovelly this morning (Friday) on a mission to hunt great white sharks. Filming for a new ITV documentary, the expedition will drag the carcass of a 30-foot whale across the Irish Sea in a bid to prove the super predators exist in UK waters. It is believed to be the first whale-fall experiment to take place in the UK, recreating what happens when a whale drops to the bottom of the ocean once it dies. The carcass, a female humpback weighing more than seven tons, will be dragged through the Celtic Deep, between Ireland and Wales, with cameras filming the response from marine life, including sharks. Ben Fogle told the Sun: Its a top secret mission so I cant talk too much about it but it could be the most exciting and ambitious thing Ive ever done. We might change what we know about the British Atlantic waters and whats in them. The Shark Trust said its former chairman, Richard Peirce, had investigated more than 100 sightings of great whites in Britain, describing a handful of the sightings as credible. The availability of seals as prey and habitat is considered well-suited to the species, but there is no evidence that they inhabit UK seas. John Richardson, the charitys conservation officer, said: This is certainly an exciting project - possibly unprecedented in British waters - however the likelihood of encountering a white shark is incredibly low. He added: Nevertheless a decomposing whale may prove impossible to ignore for a number of other magnificent oceanic sharks that are found in British waters, including the blue shark, porbeagle, shortfin mako, thresher - possibly even a Greenland shark. Big Wave TV, the production company behind the project, has waited over two years to find a whale suitable for the experiment. Dr Andrew Brownlow, director of Scottish Marine Animal Stranding Scheme, which supplied the whale after it had become stranded and died, said it would be amazing to see what Fogle and the team find, adding: The whale is a huge ecological resource so as it begins to sink it generates its entire own ecology, because it is a food source for lots of lots of creatures. The deep ocean environment is pretty sterile. There arent a lot of nutrients, so putting something massive like that in, its a huge injection of food energy into the sea.
