One of the most abundant and widely distributed stream fishes in the Ozarks, the northern hogsucker has a large, bony, square head. The mouth is at the tip of snout on the bottom; the lips are highly protrusible and covered with bumps. There are usually four dark crossbars.
The golden redhorse is a smaller-bodied sucker with large scales and a short dorsal fin. The lower lip is broken into parallel folds, and the rear margin of the lower lip forms a V-shaped angle.
Shorthead Redhorse Sucker
The shorthead redhorse is a slender, coarse-scaled sucker with a short dorsal fin and bright red tail. The head is shorter than those of other redhorse suckers.
River Redhorse Sucker
The river redhorse is a moderately chubby, coarse-scaled sucker with a short dorsal fin and bright red tail.
A smaller-bodied sucker with fine scales, the white sucker has a short dorsal fin and lips covered with small bumps. Its coloration makes it almost invisible when resting on a gravel stream bed.
