The video shows a large shark swimming in the ocean. The shark is white and has a pointed nose and sharp teeth. It is swimming slowly and gracefully, with its fins and tail moving smoothly through the water. The ocean is a deep blue color, and there are small fish swimming around the shark. In some frames, a scuba diver is visible in the background, observing the shark. The shark appears to be calm and undisturbed by the presence of the diver.
