Two years ago ,Hannah Mighall ,then 13, survived a great white shark attack on Tasmania’s north-east coast, but despite the terrible scars ,the shy yet courageous teenager is determined to get back into the water.

It’s been a long journey back for the brave girl, whose life was changed forever as she was on her surfboard 60 metres offshore at Binalong, Bay ,Tasmania.

Her cousin ,32-yeaf-old syb Mundy ,was surfing nearby, “Suddenly, everything went quiet ,”Hannah ,now15,recalls of the day she almost lost her life, “I look down into the water and noticed a dark shadow under my board I knew instantly it was a shark.”

As Syb watched in horror, the five-metre shark put hundreds of sharp teeth onto Hannah’s right leg,throwing her from her board, “I was attached to my leg-rope as the shark stared to pull me under the water”,She shakes, “I was lying on my back with one leg under the shark’s body and the other still in its jaws.”

Syb desperately punched (猛击)the shark’s nose and reached out to grab Hannah as the monster bit a huge chunk(大块)from the surfboard, “I was still attached to my board and was dragged back under the water again,”she says ,When she came up for air, Hannah dog paddled(爬泳)to Syb’s board and he dragged her from the water to lie on his back ,”We looked down and saw the shark circling beneath us,”Hannah says.

Hannah was rushed to the hospital by helicopter ,She needed more than 400 stitches(针)on her leg and spent two weeks in hospital.

Modest about her remarkable courage, Hannah owes her survival to Syb’s bravery and the fact that great whites,despite their reputation as man-eaters, typically don’t target humans ,After the attack ,Hannah earned the Sea Shepherd award for courage for speaking in defence of the shark “I was in his territory, she wasn’t in mine,”she smiles.
