Unhooking a tiger shark is a job best left to those experienced at dealing with one of the sea’s most feared predators, but the fish’s formidable teeth didn’t deter these amateurs fishing off a beach in Coral Bay, western Australia. They climb on its back and remove the hook with what looks like a set of pliers after covering its eyes with a red towel. They then steer it back into the sea, watched by a crowd of fascinated onlookers (who were probably waiting for one of those involved to lose a foot or a hand). Estimates of the fish’s size range up to 800lb and 12ft, but it looks a lot smaller to us. There are no obvious signs of a rod, though the video only starts when the shark is on the edge of the surf. We would suggest that if you’re fortunate enough to hook a tiger shark, that you don’t follow the example of those in this film. But then again,  Australians are renowned for liking a bit of excitement…Watch the video here. Meanwhile, surfers and businessmen are pressuring the government to set drum lines to catch and kill large sharks (mainly great whites)that swim close to popular surfing beaches. It follows a fatal attack last month on 35-year-old surfer Chris Boyd, at Umbies, south of Perth, a popular surf spot.
