Description:

Dorsal spines: 10 (4th or 5th spine the longest); Dorsal rays: 9; Anal spines: 3; Anal rays: 8.

Body moderately deep. Snout moderately short and blunt, its dorsal profile nearly straight. Dorsal profile near eye nearly straight or slightly convex. Interorbital space 
convex. Posterior nostril an oblong longitudinal opening. Eye situated close to dorsal profile. Cheek moderately high and without scales. Posterior angle of the operculum is 
fully scaled. Lateral teeth in jaws with strong molars. Outer surface of maxilla with a distinct longitudinal ridge. Inner surface of pectoral fin covered with scales. 5 1/2 
scale rows between lateral line and base of middle dorsal fin spines.

Size:

Maturity: Lm 21.3 cm TL, range unknown. Max length : 40.0 cm TL; common length : 25.0 cm TL.


Habitat and Ecology:

Inhabits sandy areas near reefs (depth 1-40 m) during daytime, sometimes in small groups. At night they are solitary and range over reef-flats and slopes, in depths as 
shallow as 1 m, where they feed primarily on echinoderms, mollusks and crustaceans. It is a short-lived, fast growing species with a high natural mortality rate. 


Fishery Status:

This species is not protected or subject to fishery regulations. It appears to be a rare component of the catch but this is hard to quantify beacuse of its basic similalrity 
to other more common species.
