The video shows a fish swimming in the ocean. The fish is dark in color with a light-colored underbelly. It has a long, pointed snout and large, fan-like fins that it uses to propel itself through the water. The fish's eyes are small and beady, and it appears to be alone in the frame. The water around the fish is dark, suggesting that the video was taken at a significant depth. There are no other fish or objects visible in the video.
