Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 15; Anal spines: 0; Anal soft rays: 10 - 13; Vertebrae: 52 - 57. Greatly prolonged, beak-like lower jaw; upper jaw short, triangular and without scales; preorbital ridge absent; total number of gill rakers on first gill arch 33-46; pectoral fins long, reaching beyond anterior margin of nasal pit when folded forward; no spots or vertical bars on sides.
