The video shows a large whale swimming underwater. The whale is grey in color and has a smooth, streamlined body. It moves gracefully through the water, with its flippers and tail fin propelling it forward. The whale's eyes are visible, and it appears to be calmly exploring its surroundings. The water is clear, and the light from above creates a beautiful effect on the whale's skin. There are no other creatures or objects in the video, just the whale and the vast expanse of the ocean.
