Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 13 - 15; Anal spines: 3; Anal soft rays: 12 - 13. grey with longitudinal brassy stripes on body and 2 brassy horizontal bands on head. Opercular membrane slightly pigmented. Each jaw with a regular row of close-set, strong, incisor-like, round-tipped teeth of a peculiar hockey-stick shape, their bases set horizontally, resembling a radially striated bony plate inside mouth (Ref 52729).

Biology     Glossary (e.g. epibenthic)

Inhabits shallow waters, especially over rocky bottoms in coral reef areas; also among floating Sargassum weeds (Ref. 3725). Feeds on algae including much Sargassum (Ref. 5521). Marketed fresh (Ref. 3725).
