The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, but its tail is visible above the water. The whale's tail is large and has a distinctive shape, with a wide base that tapers to a point. The water is calm, and the sun is setting, casting a warm orange glow on the scene. The whale's skin appears smooth and is a dark color, contrasting with the bright water. The whale moves slowly and gracefully through the water, occasionally causing ripples and waves.
