This is the moment a disabled sea turtle swam for the first time after being given a prosthetic flipper. Rocky was fitted with the custom-made limb after spending close to two decades struggling to swim underwater. The green sea turtle, aged between 25 and 30, was hit by a boat as a young adult which resulted in him losing his front right flipper and suffering shell damage. Prosthetist Kevin Carroll heard the tragic tale and enlisted his team at the Hanger Clinic to build Rocky a special false limb.
