Flounder Fish Illustration - Scientific Drawing of Flatfish Anatomy #109630 (License: Personal Use)

This precise black-and-white engraving depicts a flounder (family Pleuronectidae), emphasizing key anatomical features such as its flattened, oval-shaped body, both eyes positioned on the left (ocular) side, and scattered dark ocelli across the dorsal surface. The fine cross-hatching technique renders texture and depth, typical of 19th- to early 20th-century ichthyological plates used in taxonomic works. The fish’s small pectoral fin, heterocercal tail, and slightly protruding mouth are rendered with scientific accuracy.

This image is typically used in educational contexts-marine biology textbooks, museum exhibits, or online species databases-to illustrate flatfish morphology and camouflage adaptations. It serves users seeking authoritative visual references for identification, taxonomy, or evolutionary biology study.
