 A crescent-shaped notch is present on the caudal peduncle just before the upper caudal fin origin.The caudal fin is asymmetrical, with a strong lower lobe and a longer upper lobe with a ventral notch near the tip.The roughly diamond-shaped dermal denticles are placed closely together and slightly overlapping; each bears five to seven (three in juveniles) horizontal ridges leading to marginal teeth.
