The Utah sucker (Catostomus ardens) is a species of freshwater fish in the family Catostomidae found in the upper Snake River and the Lake Bonneville areas of western North America where it lives in a wide range of habitats. It is a large sucker growing up to 25 in (64 cm) long. It is generally blackish above, vaguely streaked and blotched, with a white belly. A narrow rosy lateral band extends backwards from the head. The mouth has thick lips and is on the underside of the head. Some populations are in decline because of anthropogenic factors but overall this fish is not threatened.
