The Giant Trevally (Caranx ignobilis) is the largest member in the Trevally family Carangidae. It is a ferocious predator and feeds on other fish species as well as crustaceans and cephalopods. It can be found in the waters of the Indo-Pacific region and has been recorded from the Red Sea, east Africa, Hawaii, Marquesas Island in French Polynesia, south Japan and northern Australia. In Australia it is known to occur from Exmouth in Western Australia around the north to the Solitary Islands in northern New South Wales. The body is silver in colour with numerous small scattered black spots. It is generally solitary however large adults can form small groups, particularly around dive sites where they may be fortunate enough to get food from divers. They can be found from the surface to 80 metres. The Giant Trevally (Caranx ignobilis) grows to a maximum length of approximately 1.7 metres and can weigh up to 62 kgs.
