Morphology | Morphometrics
Diagnosis: a black outer ring surrounding a bright yellow ring in iris of the eye; faint to bright white stripe originating on snout below ventro-anterior margin of orbit and continuing posteriorly along ventral margin of orbit to preopercular series of pores, ending or continuing much diminished in intensity to posterior margin of opercle; pale-margined, dark spot, smaller than pupil of eye, present on post-orbital margin at about 2 o'clock position. Body more or less uniformly olive-brown or with the indications of fine, greenish yellow, stripe-like area along dorsal body contour below dorsal fin, paralleled ventrally by broad, olive-brown area grading ventrally and narrowly to greenish yellow at body midline, then abruptly whitish below (Ref. 55736).
Adults are found in clear coastal to outer reef habitats to about 20 m depth (Ref. 48636), perched on live corals in sheltered reefs (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
