This finely detailed engraving depicts the Atlantic cod (Gadus morhua), highlighting its elongated body, three dorsal fins, two anal fins, and characteristic chin barbel. The shading and stippling techniques emphasize musculature, scale texture, and the speckled lateral line-typical of 19th-century natural history illustrations. The fish is shown in profile with mouth agape, suggesting feeding behavior.
