underwater

A massive school of fish forms a swirling, cylindrical structure above a coral reef, moving in a coordinated, flowing motion that shifts and undulates across the frame. The fish maintain a tight formation, creating a dynamic, tunnel-like shape that rotates and changes position over time, with individual fish occasionally breaking away and rejoining the main mass. The scene is set underwater, with the reef visible below and sunlight filtering down from above, illuminating the water and highlighting the movement of the fish.
