The video shows a large whale swimming in the ocean. The whale is predominantly gray in color, with a smooth and streamlined body. It has a long, curved tail and a pointed nose. The whale moves gracefully through the water, with its body undulating in a slow, rhythmic motion. The ocean around it is a deep blue, and the light from above creates a shimmering effect on the whale's skin. There are no other creatures or objects in the frame, just the whale and the vast expanse of the ocean.
