Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 31-37; Anal spines: 3; Anal soft rays: 27 - 31. This species is characterized by the following: D VIII+I,31-36+1; A II+I,27-30+1; lateral line scales, curved 58-75 and without scutes, straight 14-29 with 24-40 scutes, total 110-137; gill rakers 10-13 + 34-38; rear end of upper jaw moderately rounded and slanted anteroventrally; no teeth on upper jaw; interorbital scales usually extending to above front margin of the pupil; color bluish green and slivery below; caudal fin yellow-green and dorsal fin lobe sometimes dark distally; with a small, black opercular spot (Ref. 3197, 11228).

Biology     Glossary (e.g. epibenthic)

Adults prefer clear oceanic waters, frequently around islands (Ref. 5217). Sometimes they are found near the surface, but generally caught between 40 and 200 m depth (Ref. 9283). Pelagic (Ref. 58302). Usually seen as fast moving schools along the reef edges near deep water (Ref. 48635, 26235). They feed mainly on zooplankton (Ref. 9283). Eggs are pelagic (Ref. 4233). Marketed fresh and salted or dried (Ref. 9283).
