Young Lake Sturgeon are tan, or buff-colored, sometimes contrastingly blotched with dark, becoming more uniformly dark as they grow older. Adults are slate-gray to black above and light beneath. Its body is partially covered with five longitudinal rows of heavy, bony plates or scales. Its head is roundly pointed, and not flattened. Spiracles, or openings from the throat cavity to the outside above and behind the eyes, are present. Its mouth is inferior and almost sucker-like, capable of being protracted to easily suck foods off the bottom. The fish feeds entirely by taste and has four fleshy barbels on the underside of the snout, which act as sense organs to judge the distance from the mouth to the bottom.
