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 moves slowly and gracefully through the water, occasionally breaking the surface with its tail. The ocean is calm, with small waves lapping against the whale's body. The color of the water is a deep blue, and the whale's skin appears to be a dark gray. There are no other objects or creatures visible in the video, and the focus is solely on the whale and its movements.
