Greater Amberjack - Seriola dumerili - Passing above the Rozi Wreck

A solitary Greater Amberjack swims through the blue water above the Rozi wreck at Ċirkewwa, Malta.

The Greater Amberjack (Seriola dumerili) has a powerful, elongated and streamlined body that is moderately compressed from side to side, with a well-developed head, narrow caudal peduncle and deeply forked tail. Its colour is generally bluish-grey or olive above and silvery-white below, often with an amber or yellowish stripe running along the middle of the body. A strong and fast-swimming predator, it inhabits open water as well as rocky reefs, offshore structures, wrecks and steep coastal drop-offs. Greater Amberjacks feed mainly on fishes together with squid and crustaceans and may occur alone or in small groups. The species is widespread throughout the Mediterranean and other tropical and warm-temperate seas, commonly occurs at depths of about 18–72 metres and can reach approximately 190 centimetres in total length. This photograph shows a solitary Greater Amberjack swimming above the Rozi wreck at Ċirkewwa, Malta, where the scuttled tugboat has developed into an artificial reef supporting abundant marine life.
