Max length : 30.0 cm SL macho / no sexado; (Ref. 5179); common length : 20.0 cm NG macho / no sexado; (Ref. 45168); peso máximo publicado: 357.40 g (Ref. 124149)
Espinas dorsales (total) : 5 - 7; Radios blandos dorsales (total) : 31 - 35; Radios blandos anales: 31 - 35. Body brownish, fins darker except first dorsal. With 4 or 5 irregular darker cross-bars, inside of mouth and branchial cavities blackish (Ref. 11892).
Body shape (shape guide): fusiform / normal.
