🐟 Physical Description
Dorsal spines (total): 16; Dorsal soft rays (total): 10 - 11; Anal spines: 3; Anal soft rays: 8 - 9.

It further differs from C. bilineata by having two complete scale rows between the upper lateral line and the base of the last dorsal spine and one additional row of very small scales in-between vs. one complete scale row and one additional scale row with smaller dorso-ventrally compressed scales between the upper lateral line and the base of the last dorsal spine; and a longer last dorsal spine, 12.9-15.0% of standard length vs. 9.4-13.2% . It further differs from C. crassa by lower body depth with only a minimal overlap, 37.4-42.1% of standard length vs. 40.4-48.4% .
