The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its back and tail visible above the water's surface. The whale's skin is dark gray, and it moves slowly and gracefully through the water. The ocean is a deep blue color, and the waves are small and gentle. The whale's tail moves in a slow, undulating motion, creating ripples and splashes in the water. There are no other visible creatures or objects in the video, and the focus is solely on the whale and its movements.
