The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its back and tail visible above the water's surface. The whale's skin is a dark gray color, and it has a distinctive white stripe running down the center of its back. The whale's tail is large and powerful, and it moves in a slow, undulating motion. The ocean water is a deep blue color, and the sunlight reflects off the surface, creating a shimmering effect. There are no other visible objects or creatures in the video, and the whale is the sole focus.
