A super-fit shrimp has become a massive internet hit after learning to run on a treadmill as part of a unique science experiment.

Scientists discovered the shrimp's need for speed after it was placed on a home-made exercise machine in a tank of water to see how far it would travel for food.

Scientists were amazed with the results which showed the crustacean could jog at speeds of 66ft per minute and go on for three hours before needing a rest.
