The video shows a large whale swimming in the ocean. The whale is seen from different angles as it moves through the water. The whale's body is dark blue in color, and it has a large tail fin that it uses to propel itself through the water. The whale's skin is smooth and shiny, reflecting the light from the surface of the water. The ocean water is a deep blue color, and there are no other visible creatures or objects in the video. The whale appears to be alone in the vast expanse of the ocean.
