I am flying over an alien landscape. Gliding effortlessly with the current, I steer towards a small, rocky outcropping with small movements of my feet. The sand and rocks of the surface slide by only 7 or 8 feet below. I feel like Superman.
Just ahead, I see another creature approach.
The largest shark I have ever seen glides silently by. He is longer than I am from the top of my head to the tip of my fins- at least 8 feet.
Same planet, different world.
