The video shows a large whale swimming in the ocean. The whale is mostly submerged, with only its back visible above the water's surface. The whale's skin is dark gray, and it appears to be a humpback whale. The ocean water is a deep blue color, and the sun is shining brightly, causing the water to sparkle. The whale moves slowly and gracefully through the water, occasionally causing ripples and waves. There are no other visible creatures or objects in the video.
