Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 20; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 19 - 21. This species is distinguished from its southwestern Atlantic congeners by the following set of characters: D XX,11-12 (rarely XXI,10); A II,19-21; pectoral rays 14; length of third pelvic ray contained 2.5 to 3.0 times in second pelvic-fin ray; lateral-line scales 51-53; total nuchal cirri 12-16; presence of pre-dorsal scales and pre-pectoral scales, when present are considerably smaller than scales on body; breast usually fully scaled on males, often naked on females; one pore, rarely absent, extend from preopercular canal onto opercle. Colouration: body with 5-6 saddle-like bars that do not extend on dorsal fin; two thin white bands on upper lip usually extending to snout (Ref. 123106).
Occurs in shallow reefs and tide pools, usually in clear waters where it feeds on small benthic invertebrates (Ref. 123106).
