Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 37.8, range 28 - 50 cm
Max length : 66.0 cm TL macho / no sexado; (Ref. 56527); common length : 44.1 cm TL macho / no sexado; (Ref. 56476); peso máximo publicado: 550.00 g (Ref. 56476); edad máxima reportada: 10 años (Ref. 56527)
Espinas dorsales (total) : 2; Espinas anales: 0. Snout short, blunt, with a broad spinous scute at its tip, its leading edge and most of its underside naked; suborbital shelf very narrow anteriorly; interopercle broadly rounded posteriorly; chin with very short barbel. Scales rather deciduous; body scales with 3 to 10 low, subparallel rows of spinules; gill and gular membranes and interopercle naked. Pyloric caeca short, 5 to 7. Overall color is grayish brown; fins blackish to dusky; oral and gill cavities blackish.
Feeds mainly on pelagic forms (Ref. 1371). Too small for fresh consumption (Ref. 1371).
