deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 58 - 63; Duri dubur: 0; Sirip dubur lunak: 28 - 31; vertebrata, bertulang belakang: 68 - 72. Resembles A personatus in body shape but distinguished by its numerous dorsal fin rays (58 to 63 against 55 to 59) an vertebrae (68 against 67), and larger eyes. Lateral plicae 144 to 161.
May occur in large schools near the surface both inshore and offshore, but also buries itself in sand (Ref. 2850). Inshore, found from intertidal to subtidal areas (Ref. 2850). Offshore, found near the surface over deep water (Ref. 2850). Benthic (Ref. 58426). Juveniles and adults feed on zooplankton (Ref. 28499). Utilized dried or salted and frozen; sometimes targeted as a raw material for fishmeal; eaten fried (Ref. 9988).
