🐟 Physical Description

Dorsal spines (total): 10; Dorsal soft rays (total): 13; Anal spines: 3; Anal soft rays: 14. This species is distinguished by the following set of characters: body depth at pectoral fin base 2.5-2.9 in SL, at mid-trunk 2.4-2.9 SL; dorsal-fin origin is above the bases of the pectoral fins; preopercle with a slightly elongate and blunt spine reaching or beyond the posterior margin of the interopercle; dorsal-fin base, 1.7-1.8 in SL; anal-fin base 2.5-2.8 in SL, relatively short; eye is relatively large, its diameter 2.0-2.6 in HL; interorbital space is narrow, its width 3.3-4.1 in HL; head length 1.1-1.3 in body depth; caudal-peduncle length 2.5-3.2 in body depth; pored lateral-line scales 59-78; lateral scale rows 81-96; transversal scales rows 10-12 + 49-57 = 60-69 .Cross section: compressed.
