The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its back and tail visible above the water's surface. The whale's skin is dark gray, and it has a smooth texture. The ocean water is a deep blue color, and there are small waves visible on the surface. The whale moves slowly and gracefully through the water, occasionally breaking the surface with its tail. The video is shot from a distance, and the whale is the only visible object in the frame.
