The video shows a large shark swimming in the ocean with a school of smaller fish. The shark is grey in color and has a streamlined body with a pointed nose and sharp teeth. The smaller fish are striped and have yellow and black markings. The water is a deep blue color, and the lighting is dim, suggesting that the video was taken in the depths of the ocean. The shark moves slowly and gracefully through the water, while the smaller fish swim around it in a coordinated manner. There are no visible landmarks or other objects in the video, just the shark and the fish in their natural habitat.
