The video shows a large whale swimming in the ocean. The whale is mostly grey in color with some white patches on its body. It has a long, curved tail and a large, round head with two small eyes. The whale is swimming slowly and gracefully through the water, occasionally moving its tail fin. The ocean is a deep blue color, and the light from the sun is shining through the water, creating a beautiful and serene atmosphere. There are no other animals or objects visible in the video.
