The video shows a large fish swimming in the ocean. The fish has a long body and fins, and it is surrounded by a group of smaller fish. The water is clear, and the ocean floor is visible, covered in rocks and plants. The large fish moves slowly through the water, its fins undulating gently as it navigates the underwater landscape. The smaller fish swim around it, some darting in and out of the frame. The colors in the video are predominantly shades of blue and green, with the fish's scales reflecting the light from above.
