The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, with only its back and dorsal fin visible above the water's surface. The whale is moving slowly and gracefully through the water, creating ripples and waves as it goes. The ocean is a deep blue color, and the sky is clear and bright. The whale's skin is a dark gray color, and it appears to be healthy and well-fed. There are no other animals or objects visible in the video, and the whale is the sole focus of the footage.
