Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 16; Anal spines: 0; Anal soft rays: 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).
Found in coastal areas, entering estuaries and brackish lagoons (Ref. 5757). Feeds mainly on small fishes (Ref. 28587). Oviparous (Ref. 205); eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).
