Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 18 - 19; Mjukstrålar i ryggfenan (totalt) : 10 - 11; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 20 - 21. Head to eye and preopercle with scales; small and palmate supraorbital tentacle; light gray or light brown body with 2 linear series of uneven brown blotches with larger dorsal series and some upper blotches joining with lower; below eye is an oblique, dark brown bar with white margin; remainder of head dark brown, blending to white ventrally; females with oblique dark bands on second and third dorsal fins, darkening as they cross rays; uneven, vertical dark bars on caudal fin; yellow or orange dorsal and caudal fins in males. Dorsal rays IV + XIV-XV (typically XV) + 10-11 (typically 11); lateral line discontinuous, 21-24 + 14-19; mandibular pores 5-6 + 1 + 5-6 (Ref. 54980).
Body shape (shape guide): elongated.
Adults are found in intertidal pools in coral reef areas (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
