The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its dorsal fin visible above the water's surface. The ocean is calm, with small waves lapping against the whale's body. The whale's skin is a dark gray color, and its dorsal fin is pointed and sharp. The whale moves slowly and gracefully through the water, occasionally breaking the surface with a gentle splash. The video captures the majestic beauty of this marine creature in its natural habitat.
