The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, with only its back and dorsal fin visible above the water's surface. The whale's skin is dark grey, and it moves slowly and gracefully through the water. The ocean is a deep blue color, and the sunlight reflects off the water's surface, creating a shimmering effect. There are no other objects or creatures visible in the video, and the whale is the sole focus.
