Scientists Discover Why Sharks Can Swim So Fast

MediaSight writes "Shortfin mako sharks can shoot through the ocean at up to 50 miles per hour (80 kilometres an hour). Now a trick that helps them to reach such speeds has been discovered — the sharks can raise their scales to create tiny wells across the surface of their skin, reducing drag like the dimples on a golf ball."

    Indeed it was. We've known that the lasers make them go fast for years. I mean, come on guys, the lasers go at the speed of light, of course they make the sharks go fast!
