Flounder Anatomy Diagram - Scientific Illustration for Marine Biology #109625 (License: Personal Use)

This precise black-and-white line drawing depicts a flounder, a demersal flatfish known for its bilateral asymmetry where both eyes migrate to one side during development. The illustration clearly shows the elongated dorsal and anal fins, the small pectoral fin, and the lateral line indicated by a dotted line. Fine cross-hatching renders texture and depth, typical of 19th- or early 20th-century ichthyological plates.

Used in educational materials, textbooks, museum exhibits, or online marine biology resources to explain flatfish morphology and evolutionary adaptations. Matches user intent for academic study, species identification, or historical scientific illustration appreciation.
