The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its back and dorsal fin visible above the water's surface. The whale's skin is a dark gray color, and it appears to be moving slowly through the water. The ocean is a deep blue color, and the water is relatively calm, with small waves visible around the whale. There are no other objects or creatures in the video, and the focus is solely on the whale and its movements.
