Body shape (shape guide): elongated; Cross section: circular.

Biologie     Verklarende woordenlijst (bv. epibenthic)

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).
