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 gray, and it appears to be a humpback whale. The ocean is calm, with small waves lapping against the whale's body. The whale moves slowly and gracefully through the water, occasionally breaking the surface with its tail. The video captures the majestic beauty of the whale in its natural habitat.
