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 ocean is a deep blue color, and the water is choppy, with white foam forming around the whale as it moves. The whale's skin is a dark gray color, and it appears to be a humpback whale based on the shape of its dorsal fin. The video is taken from an aerial perspective, possibly from a drone or helicopter, as the camera angle is high above the water.
