Sucker
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.
