Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 8. This species is characterized by the following: a wide interorbital region (80-100% pupil diameter); the second dorsal spine usually reaching posteriorly to between the bases of the second to third dorsal fin rays; pectoral rays 15-16, usually with 7-8 branched rays; vertical rows of sensory papillae below eye of 2-3 papillae in rows 1-4 and 4-5 in row 5; caudal blotch which has a lower half about two-thirds the width of the upper half; usually an overall yellowish body with yellow at least proximally in the caudal fin (Ref. 87358).
Inhabits current-prone reefs in 12-70 m (Ref. 90102).
