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 dark gray, and it appears to be moving slowly through the water. The ocean is a deep blue color, and the waves are small and gentle. The whale's movements cause ripples and splashes in the water, but it does not breach the surface. The video captures the serene and majestic presence of the whale in its natural habitat.
