Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 14.0 cm TL Männchen/unbestimmt; (Ref. 402)
Rückenflossenstacheln (insgesamt) : 12 - 15; Rückenflossenweichstrahlen (insgesamt) : 8 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 9 - 11.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Primarily a near-shore pelagic species (Ref. 30573), but swims mainly in open water away from reefs (Ref. 48636). Forms dense aggregations (Ref. 90102). Mixed with other planktivores and is easily overlooked. Feeds on zooplankton (Ref. 30573). Oviparous, with numerous, small pelagic eggs (Ref. 402). Caught at night using lights and dip nets (Ref. 30573). Important tuna bait fish in some countries (Ref. 30573).
