Etymology: Scorpaenopsis: Latin, scorpaena = a kind of fish, 1706 + Greek, opsis = appearance (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 1 - 40 m (Ref. 34765), usually - m (Ref. ). Tropical; 0°C -

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 34765); common length : 20.0 cm SL male/unsexed; (Ref. 37816)
soft rays: 5. Snout length > orbit diameter. Has a dark purplish blotch on the rear of the spinous dorsal fin (Ref. 37816). Juveniles with large, forward pointing tentacles above the eyes (Ref. 48635). Space on opercle between opercular spines scaled; penultimate dorsal spine 1.9-2.2 in length of last spine; reaches 195 mm SL (rarely over 170 mm) (Ref 42181).
Found in coral and rocky areas to depths over 40 m (Ref. 34765); also in coastal and slopes, estuaries and lagoons, often in algae covered rubble zones (Ref. 48635). Feeds on fishes (Ref. 89972). Solitary and difficult to see due to camouflage colors (Ref 90102).
