Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 17 - 22; Spine anali: 2; Raggi anali molli: 7 - 9. Body nearly uniform silvery, dark greenish above. Without conspicuous spots on side but with diffuse dark areas along base of dorsal fin and on margin of spinous dorsal fin, ventral side of head, lower margin of pectoral, pelvic, and caudal fins often yellowish orange. Inside of opercle dusky. Mouth large, oblique. Lower jaw slightly projecting. Upper jaw with a pair of large canine-like teeth at tip. Lower jaw with a row of enlarged inner-row teeth, gradually increasing in size posteriorly. Chin without barbels or pores. Snout with 2 marginal pores. Pectoral fins about equal in length to pelvic fins. Gas bladder with a pair of long, straight, horn-like appendages. Sagitta earstone thin and elongate. Soft portion of dorsal fin unscaled except 2 or 3 rows of small scales along its base (Ref 51271).
