The image is a vintage x-ray or radiograph of a fish skeleton. The fish is viewed from the side, showing its complete skeletal structure. The spine is clearly visible as a series of small, connected bones running the length of the body. Ribs extend from the spine, forming a cage around the internal organs. The skull is detailed, showing the structure of the head. The tail fin and pectoral and pelvic fins are also visible, showing the delicate bone structure. The image is monochromatic, with the bones appearing as bright white against a dark background. The overall effect is a detailed and somewhat eerie depiction of the fish's internal anatomy. There is text at the bottom of the image that reads 'Solefish (Pleuronectes solea)'.
