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 is a dark gray color, 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.
