Greater Amberjack - Seriola dumerili - Solitary in Deep Blue Water

A solitary Greater Amberjack swims through dark blue open water, its silvery body, faint amber stripe and deeply forked tail clearly visible.

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 a yellowish or amber stripe running along the side. A strong and fast-swimming predator, it inhabits open water as well as deep offshore reefs, rocky structures 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, is commonly encountered at depths of about 18–72 metres, and can reach approximately 190 centimetres in total length.
