The video shows a large whale swimming in the ocean. The water is calm and the sky is overcast. The whale's body is mostly submerged, with only its back and dorsal fin visible above the water's surface. It moves slowly and gracefully, occasionally breaking the surface with a gentle splash. The whale's skin is dark and smooth, and it appears to be a humpback whale based on the shape of its dorsal fin. The video captures the whale's movements from different angles, providing a clear view of its size and grace.
