Overview

Comprehensive Description

Biology

Inhabits surge-swept tunnels and crevices of the reef margin and reef front. Rarely occurs below 30 m, but has been observed at depths of 101 to 183 m in the Hawaiian Islands (Ref. 1602); majority of specimens collected in less than 3 m, often in tide pools (Ref. 27370). Benthopelagic (Ref. 58302). It disperses at night over sand flats and open reef bottom to feed on small crustaceans, crustacean larvae, and polychaete worms. Spine of preopercle venomous. Minimum depth reported taken from Ref. 30874.
