Walleye Fish: Anatomy, Habitat, and Fishing Guide #28747 (License: Personal Use)

This anatomical illustration depicts a walleye (Sander vitreus), a freshwater perciform fish native to North America, known for its large, light-reflecting tapetum lucidum eye that enhances low-light vision. The fish displays characteristic features: a elongated body, spiny first dorsal fin, pale pinkish pelvic and anal fins, and a silvery-white ventral surface contrasting with its olive-brown back. Its mouth is slightly open, revealing sharp teeth adapted for predation on smaller fish and invertebrates.
