Ecology Summary - Caranx sexfasciatus

Language:

Main Ref.	Honebrink, R., 1990
Remarks	Inhabits coral reefs (Refs. 58534, 9773), coastal and oceanic waters associated with reefs (Ref. 9283). Commonly encountered on the edge of coral reefs. Young occurs in brackish water areas out to deeper coastal waters. Juveniles may be encountered in estuaries (Ref. 9283, 44894), occasionally entering rivers and penetrating well inland (Ref. 2847, 44894). Adults are found in coral reefs and are mostly active at night or during twilight periods. During the day they are usually seen milling in stationary aggregations (Ref. 44894). Occasionally enters rivers (Ref. 9283). Forms slow-moving schools in the passes or outside the reef during the day, dispersing at night to feed (Ref. 4795). Most feeding occurs at night or during twilight (Ref. 54301). Piscivore (Ref. 57615). Feeds mainly on fishes and crustaceans (Refs. 9283, 9773). Hunting predator (Ref. 9773).
