Slate-gray to gray-blue above, fading to somewhat lighter beneath. They can easily be distinguished from all other Iowa fish by the immensely elongated snout, extremely long gill covers and shark-like mouth. The skeleton is largely cartilaginous. Jaws and palate of young fish are covered with numerous fine teeth, but the jaws become large, feeble and toothless as the fish reaches maturity. The body is naked, or scaleless.
