Common in coastal waters and lagoons with mangroves (Ref. 9279). Also found near the surface of offshore waters (Ref. 11035). Feeds mainly on small fishes (Ref. 9279). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Usually caught with the help of artificial lights (Ref. 9279).
