Max length : 84.0 cm TL macho / no sexado; (Ref. 124151); peso máximo publicado: 5.1 kg (Ref. 124151)
Espinas dorsales (total) : 2; Radios blandos dorsales (total) : 124 - 125; Espinas anales: 0; Radios blandos anales: 110. Eyes relatively large. Snout short, moderately pointed, usually somewhat rounded with a high dorsal profile in adults, but often with prominent tubercles at its tip and lateral angles. Mouth large, lips thin.
