পৃষ্ঠীয় কাঁটা (মোট ) : 13; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 9 - 11; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 10. Reddish, darker (bluish grey) dorsally, silvery white below (Ref. 5325).
A schooling species (Ref. 9563). Reported from between depths of 86 m (Ref. 58489) and 500 m (Ref. 5325). Juveniles occur near the surface, often with schools of clupeids while adults are found near the bottom in deeper water (Ref. 3394). Adults feed mainly on larger zooplankton (Ref. 3394). An excellent food fish; marketed fresh or frozen (Ref. 3394).
Asynchronous batch spawner with indeterminate fecundity (Ref. 115109). Spawns once every 3-5 days (Ref. 115109).
