Ecology of Nebrius ferrugineus
Main Ref. Compagno, L.J.V., 1984
Remarks Prefers sheltered areas in crevices and caves on reefs but often occurs in more exposed areas in a depression or crevice. Mainly nocturnal, resting during the day. Gregarious and form resting aggregations of two to half-dozen or more in shelters, and are often seen piled across or on top of one another. It uses its large pharynx as a powerful suction pump to rapidly inhale in reef organisms that may be out of reach of its teeth. However, they may reverse this sucking action and blast streams of water out of their mouths into the faces of their captors, making grunting sounds between streams.
