Geschlechtsreife: Lm 16.8  range ? - ? cm
Max length : 35.0 cm TL Männchen/unbestimmt; (Ref. 3197); common length : 25.0 cm TL Männchen/unbestimmt; (Ref. 9137)
Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 33 - 38; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 27 - 30. Body slender, elongate, and somewhat circular in cross section; posterior end of upper jaw concave dorsally and with a rounded protrusion ventrally; edge of shoulder girdle (cleithrum) with two small papillae, the lower one larger; dorsal and anal fin each followed by a separate finlet (Ref. 55763). Color metallic blue dorsally, silvery ventrally; fins hyaline; opercle with a small black spot (Ref. 2334). 24-40 scutes. Very slender compared to similar species (Ref. 48635).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
A predominately pelagic schooling species (Ref. 9283, 48635, 58302). Occasionally seen in small groups along reef slopes adjacent to deep water in pursuit of zooplankton (Ref. 48635). Adults feed mainly on small invertebrates (Ref. 5213). Marketed fresh and salted or dried (Ref. 9283).
