Kort beskrivning Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 21 - 24; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 19 - 22; Ryggkotor: 75 - 80. This species with is distinguished by the following characters: body elongate, circular in cross-section; D 21-24 with anterior rays forming a relatively high lobe, 5.4-10.6 body length (excluding the head and caudal fin); dorsal fin origin about equal with or slightly in front to anal fin origin; A 19-22 with anterior rays forming a relatively high lobe, in 5.5-8.0 in BL; pectoral-fin rays 13 to 15 (usually 14 or 15); 270-340 predorsal scales; 75-80 vertebrae; jaws extremely long, forming a stout beak armed with very sharp teeth; no gill rakers absent; caudal fin deeply emarginate, the lower lobe much longer than the upper one and the caudal peduncle with a distinct, black lateral keel; body colour dark bluish green above, silvery below; juveniles (to 20 cm body length) with elevated black lobe in posterior part of dorsal fin which is lost with growth; scales and bones green (Ref. 9682, 90102).
Body shape (shape guide): elongated; Cross section: circular.
Body shape (shape guide): elongated; Cross section: circular.
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). Caught by casting or trolling surface or near-surface lures; also with purse seines and drift nets (Ref. 9682).
