Body oblong and moderately compressed. Dorsal fin continuous, the spinous part arched and its membrane slightly incised. Caudal fin truncated. Pelvic fin origin slightly beyond pectoral fin base. Mouth terminal, jaws extending back to the vertical line of posterior nostril. Upper jaw with three bands of teeth and two bands in the lower jaw. No vomerine or palatine teeth.
