The image is a close-up of a fish swimming in the ocean at night. The fish appears to be a pufferfish, with a round body and a pointed nose. It has a long, slender body with a pointed tail and two fins on either side. The body of the fish is covered in a transparent material, which is likely a jellyfish, and it is illuminated by a blue light. The background is dark, making the fish stand out even more. The image is taken from a low angle, looking up at the fish.
