The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, with only a small portion visible above the water's surface. The water is a deep blue color, and the whale's skin appears to be a darker shade of blue. The whale is moving slowly and gracefully through the water, with its tail fin occasionally breaking the surface. There are no other objects or creatures visible in the video, and the focus is solely on the whale and its movements.
