Walleye Identification Guide
Recognize a walleye by its glassy reflective eyes, dark blotch on the first dorsal fin, and white-tipped tail.

Key identification features
- Large, glassy, reflective eyes caused by a light-gathering layer (tapetum lucidum) that helps it see in low light
- Two separate dorsal fins, the first spiny with a distinct dark blotch at its rear base
- Olive-gold to brown body with mottled, marbled patterning along the back and sides
- White tip on the lower lobe of the tail fin, a reliable close-range field mark
- Elongated, moderately slender body shape
- Typical adult length of 35-65 cm
Common look-alikes
- Sauger: smaller on average, with distinct rows of dark spots across the first dorsal fin instead of a single blotch, and no white tail tip
- Yellow perch: much smaller with bold vertical dark bars and only one dorsal fin region set close to the body, lacking the glassy eye shine
- Zander (in areas where introduced): very similar shape but generally more uniformly gray-green with less mottling
Where you'll see one
Walleye are found in large lakes, reservoirs, and rivers across northern North America, favoring deeper, turbid, or low-light water and becoming most active near dawn, dusk, and after dark.
Frequently asked questions
How do I tell a walleye from a sauger?
Look at the first dorsal fin: a walleye has one bold dark blotch near its rear base, while a sauger has distinct rows of small dark spots instead.
Why do walleye eyes look shiny in photos?
A reflective layer behind the retina improves low-light vision and causes the eyes to glow or shine when light hits them, a feature not found in yellow perch.
