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 appears to be textured and mottled with patches of barnacles and other marine growth. The ocean water is a deep blue color, and there are small bubbles visible around the whale, indicating its movement through the water. The video is shot from a side angle, providing a clear view of the whale's size and the surrounding ocean environment.
