A thick-bodied, stout-looking fish with a rich olive-brown color on the back and sides. The sides are covered with dark brown mottlings, and the belly is light yellow. A characteristic feature is 4 or 5 reddish-brown streaks radiating from the eye across each side of the head. The iris of the eye is red, and the fins are spotted with dark brown, forming bands which are more noticeable on the soft parts of the dorsal and anal fin. It can easily be distinguished from other sunfish by the patch of small teeth on the tongue. Anglers often confuse this fish with the Rock Bass, but they are easily separated by counting the spiny rays in the anal fin; the Warmouth has 3 spines and the Rock Bass has 6 spines. The spiny dorsal fin, which is broadly connected with the soft part of the fin, has 10 spines.
