Head large, naked, and depressed above, profile slightly concave over snout; snout long, broad, and rounded; mouth large, nearly horizontal; lower jaw projecting; maxillary extending to, or slightly beyond anterior margin of pupil. Lateral teeth on lower jaw and vomer enlarged. Cheek and opercle fully scaled. Gill rakers on lateral and media surfaces of arches.
Pigmentation: Greenish above, sometimes very dark, venter pale; scales above with golden luster; laterally with light areas enclosed by dark chain-like markings; dark upper side interrupted by light vertical bars; suborbital bar almost vertical or with slight posterior slant; rays of dorsal, anal, pectorals, and pelvic fins with light interradial membranes, caudal fin base marbled with dark pigment, tips dusky; pupil of eye yellow.
Body shape (shape guide): elongated; Cross section: compressed.
Live in vegetated lakes, swamps, and backwaters and quiet pools of creeks and small to medium rivers (Ref. 26373). Also found in deep, cold water with little or no vegetation (Ref. 39109, 39108). Adults migrate to deeper water during winter (Ref. 39110, 39097, 39111) undertaking shoreward spawning migrations soon after spring ice disappears (Ref. 39109). Oviparous (Ref. 205). Juveniles tend to lie motionless near shore or burrow themselves in mud beneath debris (Ref. 39112). Larvae hide among vegetation (Ref. 39113). Oviparous, with pelagic eggs.
