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 ocean is a deep blue color, and the whale's skin appears to be a lighter shade of blue. The whale is moving slowly and gracefully through the water, creating ripples and waves around it. There are no other objects or creatures visible in the video, and the focus is solely on the whale and its movements.
