The video shows a large whale swimming in the ocean. The whale's body is mostly submerged, with only its back visible above the water's surface. The whale's skin is dark and shiny, reflecting the sunlight. As the whale moves, it creates a trail of bubbles and ripples in the water. The ocean is a deep blue color, and the sky is clear and bright. The video captures the whale's graceful movements as it navigates through the water.
