Abstract

Snout is pointed with large terminal mouth forming a low angle to the horizontal. Teeth are differentiated into large and small in both jaws. No canine teeth present. Lower gill rakers are 7 to 8. Dorsal fin spines are 9-10 followed by low notch and are with 22-24 soft rays. Pectoral fin is fairly small, a little more than half of the head. Anal fin is with 2 spines and seven soft rays. The second anal spine is strong. Rhomboid shaped caudal fin.
