A 25-year-old female loggerhead turtle named Yu swims after receiving her 27th pair of prosthetic flippers at the Suma Aqualife Park in Kobe, western Japan Feb 11, 2013. Life looked grim for Yu, a loggerhead turtle, when she washed up in a Japanese fishing net five years ago, her front flippers shredded after a brutal encounter with a shark. Now keepers at an aquarium in the western Japanese city of Kobe are fighting to find a high-tech solution that will allow the 25-year-old turtle to swim again, with years of labours and 27 models of prosthetic fins behind them without success.
