The video shows a large shark swimming in the ocean. The shark is grey in color and has a long tail. It is surrounded by small fish that are swimming around it. The water is clear and blue, and the sunlight is shining through the surface. The shark moves gracefully through the water, with its fins and tail moving in a smooth motion. The small fish seem to be swimming in a group, with some of them coming close to the shark. The shark does not appear to be aggressive and seems to be just swimming around.
