Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 6 - 7; Raggi dorsali molli (totale) : 29 - 36; Spine anali: 3; Raggi anali molli: 17 - 22; Vertebre: 24. Scutes absent. Compared to S. lalandi, the species' dorsoposterior corner of upper jaw is angular (versus rounded) and the pectoral and pelvic fins are almost equal in length (versus pectoral shorter than pelvic fin).
Adults exhibit shoaling habit (Ref. 9988). They feed on plankton. Juveniles are found among floating seaweeds (Ref. 12114, 12115). Collection of young is the basis for prosperous aquaculture in Japan. Raised in captivity and marketed fresh for sashimi (Ref. 9988).
