Locally known as yellow cat, the yellow bullhead is distinguished from the black bullhead, by its white or yellow chin barbels, 24 to 28 rays in a straight-edged anal fin, and five to eight fairly large teeth on the posterior edge of each pectoral spine. The rear edge of the caudal fin is straight or slightly rounded. The back is yellow, olive, or dark gray, grading from light yellow to white on the venter. The fins are light to dark gray, and they may have light to darkened margins. Adult size: 6 to 15 inches.
