Ecologia
marino associati a barriera corallina; distribuzione batimetrica 0 - 10 m (Ref. 89707), usually 0 - 3 m (Ref. 9710). Tropical; 30°N - 29°S, 139°E - 123°W (Ref. 5222)
Pacific Ocean: islands of Oceania; Ogasawara Islands, Marcus Islands, Mariana Islands, Marshall Islands, Phoenix Islands, American Samoa, Cook Islands, Line Islands, Society Islands, Rapa, Tuamoto Islands, and the Pitcairn Group.

Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 52.0 cm TL maschio/sesso non determinato; (Ref. 9710)
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 14 - 16; Spine anali: 3; Raggi anali molli: 8. Preopercle rounded, finely serrate; upper edge of the operculum sinuous; nostril subequal; maxilla reaches past vertical at rear edge of the eye. Pectoral fins fleshy. Head and body whitish, with small close-set blackish-brown spots, those on the rear part of the body coalesced to form irregular longitudinal bands. Four dark blotches usually at the base of the dorsal fin and a fifth forming a dark saddle blotch on the peduncle. Fins with small white spots and whitish margins, usually with a black submarginal band; body depth contained 2.9-3.4 times in SL; head length 2.4-2.6 times in SL (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
This shallow-water species is more common on atolls than high islands, and usually found in exposed outer-reef areas. Not dependent on coral cover (Ref. 89707). Juveniles and occasionally adults are collected from tide pools. Feeds on crustaceans (mainly grapsid crabs), octopi, and fishes.
