Bigeye trevallies are widely distributed across the Indo-Pacific, from the Red Sea and East Africa to Hawaii, and the Eastern Pacific, from southern California down to the Galapagos Islands. They typically inhabit depths from the surface to 480 ft (146 m) deep. They are commonly fished for consumption, both commercially and recreationally. They inhabit a range of environments from coastal reefs to offshore waters. Juveniles often migrate into freshwater and brackish water. Bigeye trevallies have a compressed body and notably large eyes relative
to their head size. They are nocturnal. They are usually seen in slow moving schools during the day at the edges of reefs. At night, they become solitary hunters. As opportunistic predators, they feed primarily on smaller fish, squid, and crustaceans. They can reach a maximum length of 47 in (120 cm). Adults are typically silvery-olive to iridescent blue-green on their upper body, fading to a silvery-white belly. There is a small blackish spot near the upper end of each gill opening. They have a dark, white-tipped dorsal fin lobe. Juveniles are a silvery yellow to silvery brown in color, and possess several dark vertical bands on
their sides. As they mature, the bands fade. For more marine facts, click the SUBSCRIBE button!
