( n. )
Any one of numerous species of North American fresh-water cyprinoid fishes of the family Catostomidae; so called because the lips are protrusile. The flesh is coarse, and they are of little value as food. The most common species of the Eastern United States are the northern sucker (Catostomus Commersoni), the white sucker (C. teres), the hog sucker (C. nigricans), and the chub, or sweet sucker (Erimyzon sucetta). Some of the large Western species are called buffalo fish, red horse, black horse, and suckerel.
