Morphology | Morphometrics
soft rays: 12 - 14;
Vertebrae: 28 - 29. Head and body with small, bright blue spots. Uninterrupted lower lip at symphysis. Dorsal and anal rays mostly unbranched and segmented. Upper part of caudal fin with 4-5 procurrent rays and 9 principal rays; the lower part with 4-5 procurrent and 8 principal rays. Disjunct lateral line; anterodorsal series of 33-43 (usually 36-40) tubed scales extending from gill opening. Usually 19 or 20 circumpeduncular scales (Ref. 37748).
Occurs inshore near reefs (Ref. 7300) and weed bed areas; usually in relatively silty waters at depths up to 30 m. A secretive species usually found at highly eroded limestone reef and rocks (Ref. 37748).
