Maturity: Lm ?  range ? - ? cm
Max length : 76.0 cm TL male/unsexed; (Ref. 2850); common length : 50.0 cm TL male/unsexed; (Ref. 9276)
Body compressed and deep; skin thick, with large, rectilinear, plate-like scales that are easily visible to the naked eye; mouth small; teeth strong and protruding, 8 in each jaw; dorsal fin with 3 spines and 26 to 28 rays; scales behind the gill openings larger than the neighboring scales; snout surrounded by scales (Ref. 55763).
