The video shows a large whale swimming in the ocean with a small fish swimming nearby. The whale is gray in color and has a large body with a long tail. The fish is smaller in size and has a yellow and black striped pattern on its body. The water is a deep blue color, and the lighting is natural, suggesting that the video was taken during the day. The whale and fish are moving slowly and gracefully through the water, and there are no other visible creatures or objects in the scene.
