Jumping and diving over rocks in a struggle for life. Magnificent creatures seeking to return to their place of birth. Noble creatures of bright and splendid colors fighting against the force of nature itself. Swimming to exhaustion, driven by some unseen force. From the cold waters of far inland rivers to deep oceans then back again. A course of life that is planned out by generations of selection through natures process of survival. Each fish must run it's course and finish where it started in order for it's species to survive.
