The video shows a large blue whale swimming in the ocean. The whale is seen from different angles as it moves through the water. The whale's body is a deep blue color, and it has a long, slender shape. The whale's tail fin is visible, and it moves slowly and gracefully through the water. The ocean is a dark blue color, and the light from the sun creates a shimmering effect on the whale's body. There are no other objects or creatures visible in the video, and the focus is solely on the whale.
