Etymology: Scorpaenopsis: Latin, scorpaena = a kind of fish, 1706 + Greek, opsis = appearance (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 4 - 60 m (Ref. 42181). Tropical; 30°N - 30°S
Eastern Central Pacific: Hawaii.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 51.0 cm TL male/unsexed; (Ref. 4887); max. published weight: 3.5 kg (Ref. 42181)
soft rays: 5. Vertical scale rows 50-55; lachrymal bone with 2 spines over maxillary, first points down and forward, second points down and back, sometimes second split distally into 2 points; suborbital ridge usually with 5 spines, sometimes some spines split in larger specimens (Ref. 10482).
This solitary species inhabits the outer edge of the reef (Ref. 583). Usually beneath ledges or near entrance to caves (Ref. 42181). Benthic (Ref. 58302). A prized food fish with population greatly reduced in main Hawaiian islands due to fishing pressure, especially by spear fishermen. Stomach contents include small fishes (holocentrid, acanthurid and Aulostomus chinensis) (Ref. 42181).
