sturgeon
sturgeon primitive fish of the northern regions of Europe, Asia, and North America. Unlike evolutionarily advanced fishes, it has a fine-grained hide, with very reduced scalation, a mostly cartilaginous skeleton, upturned tail fins, and a mouth set well back on the underside of the head. It also has widely separated rows of heavy guard scales, four barbels or feelers that hang below the head and help to locate food, and a gas bladder from which isinglass is made. Sturgeons feed by sucking in their food—e.g., crayfish, snails, larvae, and small fishes—from the water bottom through their small, toothless, fleshy-lipped mouths.
