The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, with only its head and a small portion of its back 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 only small waves visible around the whale. There is no other marine life or objects in the video, and the focus is solely on the whale.
