Most easily distinguished from N. scolopaceus by its pale color; has more postorbital and preopercular pores. Rectangle formed by the lateral line pores is shorter and higher than in scolopaceus. Resembles N. curvirostris in its pale color but the subcutaneous dark bars are not as evident. May be instantly distinguished from curvirostris by the more numerous postorbital and preopercular pores and the much shorter and higher rectangle formed by the lateral line pores. Has smaller teeth than curvirostris.
