The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, but its tail is visible above the water's surface. The whale is moving slowly and gracefully through the water. The ocean is a deep blue color, and the sunlight is reflecting off the water's surface, creating a shimmering effect. The whale's skin appears to be a dark gray color, and its tail is a lighter shade of gray. There are no other objects or creatures visible in the video, and the whale is the main focus of the footage.
