Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 20-27; Anal spines: 0; Anal soft rays: 20 - 24; Vertebrae: 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).

Biology     Glossary (e.g. epibenthic)

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).
