This is a vintage scientific plate titled "Adjustment of Flatfishes" by Francis B. Summer, labeled as Plate 8. It features five black and white photographs arranged in a grid. **Top Row:** * **Left:** A flatfish camouflaged against a speckled background. The fish is oval-shaped and has a mottled pattern that blends with the surrounding texture. * **Right:** Another flatfish, also oval-shaped, with a more pronounced speckled pattern. It appears to be lying on a sandy surface. **Middle Row:** * **Left:** A flatfish positioned against a background of vertical black and white stripes. The fish's pattern is changing to match the stripes, demonstrating camouflage. * **Right:** A close-up of a flatfish, showing its texture and pattern. It's difficult to discern the background, but it appears to be a sandy or grainy surface. **Bottom Row:** * **Center:** A close-up view of a sandy or grainy surface, likely the substrate where the flatfish are camouflaged. It's a mix of light and dark particles, creating a speckled texture. Each image is labeled with a letter and number (4f, 4g, 4h, 4i, 5) in the bottom left corner. The overall aesthetic is scientific and documentary, with a focus on demonstrating the flatfish's ability to adapt to its surroundings through camouflage.
