A solitary species that inhabits a variety of reef zones from reef flats to lagoon and seaward reefs to a depth of at least 122 m and is fairly common in areas not subjected to heavy spear fishing. Found under ledges during the day (Ref. 9710). Benthopelagic (Ref. 58302). Largest species of squirrelfish and the highest-bodied Sargocentron (Ref. 37816). Juvenile inhabits shallow protected reefs. A nocturnal species that feeds on crabs, shrimps and small fishes. Spine of preopercle venomous. Largest squirrelfish (Ref. 48635). Minimum depth reported taken from Ref. 128797.
