Maturity: Lm 47.3, range 45 - 50 cm
Max length : 153 cm TL 雄鱼/尚未辨别雌雄; (Ref. 26340); common length : 90.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 3129); 最大体重: 3.7 kg (Ref. 4699)
背棘 (总数): 0; 背的软条 (总数): 20-27; 臀棘 0; 臀鳍软条: 20 - 24; 脊椎骨: 90 - 95. Diagnosis: body elongate; upper and lower jaws extremely long, forming a stout beak armed with very sharp teeth; gill rakers absent (Ref. 57228, 90102). Nostrils in depression before eyes (nasal pit); pelvic fins abdominal; 20-26 dorsal-fin rays; anal fin short, 9.7-11.7 times in body length; small, black lateral keel on either sides of caudal peduncle; caudal fin deeply forked (Ref. 57228).
Inhabits oceanic and neritic waters (Ref. 26340). Feeds on small fishes. Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Although sold fresh and salted, its market is limited due to the green-colored flesh (Ref. 5217). Circumglobal in tropical seas and divisible into four subspecies (Ref 90102).
