Flatfish Anatomy Illustration - Scientific Fish Diagram #264990 (License: Personal Use)

This precise 19th-century-style engraving depicts a flatfish-likely a sole or flounder-with both eyes positioned on the left (ocular) side, a hallmark of adult pleuronectiformes. Fine cross-hatching renders musculature, scale texture, and fin rays, emphasizing anatomical accuracy for scientific study. The tail fin shows segmented rays, while the pectoral fin is reduced and fused near the head.

Used in educational websites, museum exhibits, marine biology textbooks, or taxonomy databases to illustrate flatfish morphology; targets students, researchers, and natural history enthusiasts seeking authoritative visual references.
