This video captures a serene underwater scene in a body of water. The water is a clear greenish-blue color, and the sunlight is shining through, creating a beautiful pattern on the sandy bottom. There are several small fish swimming around, and a large school of fish can be seen swimming in a group. The fish are dark in color, possibly black or dark gray, and they move gracefully through the water. The video is shot from an underwater perspective, giving the viewer a sense of being in the water with the fish.
