Hmm, I don’t know if this is friggin cruel or friggin funny. Scientists from the Pacific University of Oregon built the shrimp treadmill to see how far the little blighter would travel for food. Professor David Scholnick, heading the experiment, was surprised to discover the super fit crustacean could jog for hours without a break at speeds of 66ft per minute. Even more surprising was that his little science experiment video of the exercising creature became an instant hit on YouTube. Wanna see it?
