Flatfish Anatomy and Adaptations - Marine Biology Guide #3735597 (License: Personal Use)

This illustration depicts a typical flatfish, such as a flounder or sole, characterized by both eyes positioned on the upper side of its body after metamorphosis. Its brown, mottled skin with circular markings provides effective camouflage against sandy or muddy seabeds, while the elongated, spiny dorsal and anal fins aid in subtle movement along the substrate. The fish’s flattened morphology allows it to lie nearly invisible while ambushing prey.

Used in educational articles, marine biology textbooks, aquarium websites, or conservation resources to explain flatfish adaptation, evolution, and ecology; matches user intent for learning about fish morphology or ocean biodiversity.
