The video shows a large fish swimming in the water. The fish is dark in color and has a long body. It is swimming near the bottom of the water, which is covered in rocks and sand. The water is clear, and the fish is the only visible creature in the video. The fish moves slowly and gracefully through the water, its fins and tail gently propelling it forward. The rocks and sand on the bottom of the water are visible, but there are no other creatures or plants in sight. The video is shot from a distance, allowing the viewer to see the entire length of the fish as it swims.
