This stylized illustration depicts a walleye (Sander vitreus), a freshwater perciform fish known for its large, reflective eyes adapted for low-light hunting. Key anatomical features include a spiny anterior dorsal fin, soft-rayed posterior dorsal fin, forked caudal fin, and a slightly downturned mouth lined with sharp teeth. The coloration transitions from olive-green on the dorsum to silvery-white ventrally, typical of countershading camouflage.
