The video shows a large whale swimming in the ocean. The whale is moving slowly and gracefully through the water, with its body partially visible in the frame. The ocean is a deep blue color, and the whale's skin is a lighter shade of blue, with some white spots. The whale's tail fin is visible in some shots, and it appears to be a humpback whale based on its size and shape. There are no other visible creatures or objects in the water, and the video focuses solely on the whale's movements.
