Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 13 - 16; Anale stekels: 0; Anale zachte stralen: 14 - 18. Diagnosis: body elongate; upper and lower jaws extremely long, forming a stout beak armed with strong teeth; nostrils in depression before eyes (nasal pit); gill rakers absent; pelvic fins abdominal; 13-16 dorsal-fin rays; no lateral keel on caudal peduncle; caudal fin emarginated (Ref. 57228).
