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 calm, with small waves gently lapping against the surface. The sky is clear and blue, with no clouds in sight. The whale moves slowly and gracefully through the water, occasionally breaking the surface with a gentle splash. The video captures the majestic beauty of the whale in its natural habitat.
