Color: Highly variable, depending on mood of fish and color of substrate. In life, usually green grey to sandy above, paler below; sides with about 30 large spots, the largest bigger than pupil; spots evenly spaced over sides in 6 irregular rows, the upper row lying close to lateral line, their color changing from blue to cream to silvery; centres of spots much darker than perimeters in certain phases of change. Frightened and injured fish are mottled brown, with 6 darker diagonal zones alternating with 6 paler ones across head, trunk and fins; mottling includes dappling with numerous small spots, large spots often obscured. Caudal fin yellow brown, outer rays sometimes barred with paler; dorsal fin rays banded; pectoral fins hyaline; other fins mottled dark and lighter brown. After death, brown mottled with dark brown; spots absent.

Body compressed, fairly slender, its depth contained 2.2 to 2.6 times in standard length. Head pointed, upper profile only slightly concave above eye; anterior nostril with a long flap in juveniles, shortening progressively with age, the tip reaching less than halfway to posterior nostril in specimens more than 12 cm standard length. A forward-directed spine present in front of dorsal fin; longest dorsal spine 5th to 8th; last dorsal spine the shortest, but not less than half the length of longest; longest anal spine 3rd or 4th, 1.3 to 1.5 times the length of last anal spine; caudal fin forked, median rays half to two-thirds the length of longest rays. Scales minute; cheeks either scaleless or with a few to many very fine scales; 26 to 31 scale rows between lateral line and bases of leading dorsal spines.

Max. age reported: 3 years.
