Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 21-23; Anal spines: 0; Anal soft rays: 18 - 22; Vertebrae: 80 - 86. 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; 21-23 dorsal-fin rays; anal fin long, 5.5-8.0 times in body length; small, black lateral keel on either sides of caudal peduncle; caudal fin deeply forked (Ref. 57228).

A pelagic species (Ref. 26340) found over lagoon and seaward reefs. Solitary or in small groups. Feeds on fishes (Ref. 11889). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Feared by fishers because they can cause puncture wounds with their sharp snouts when jumping out of the water, e.g. when alarmed or attracted to lights at night. Although sold fresh and considered a good food fish, its market is limited due to the green-colored flesh (Ref. 5217). Widespread in tropical Indo-Pacific, divisible in two subspecies (Ref 90102).

IUCN Red List Status (Ref. 115185)

Least Concern (LC)

Threat to humans

Traumatogenic (Ref. 4690)
