Main Ref.	Holthuis, L.B., 1991
Remarks	Occurs at depths of 0 to 90 m (seldom at 150 m) on rocky substrate, especially on rocky onshore reefs with sufficient hiding places (Ref. 4). Lives in crevices of rocky shores and among algae (Ref. 4). Also commonly occurs on broken boulder areas and fractured reef (Ref. 106895). It is gregarious and nocturnal. It is carnivorous and feeds on small crustaceans, mollusks and echinoderms (Ref. 4).
