Family Catostomidae. Including: Buffalo fishes (Ictiobus species); Suckers (Catostomus species, Moxostoma species); Quillbacks or carpsuckers (Carpiodes species)

The white sucker (Catostomus commersonii) is a species of freshwater cypriniform fish inhabiting the upper Midwest and Northeast in North America, but it is also found as far south as Georgia and as far west as New Mexico. The fish is commonly known as a “sucker” due to its fleshy, papillose lips that suck up organic matter and aufwuchs from the bottom of rivers and streams. Other common names for the white sucker include bay fish, brook sucker, common sucker, and mullet. The white sucker is often confused with the longnose sucker (C. catostomus), because they look very similar.
