Also known as the Blacksaddle Coral Grouper and the Oceanic Trout, this species is found in the Indo-Pacific; in Australia, its distribution spreads from Western Australia to the Great Barrier Reef in Queensland.
This coral trout has two distinct colour phases: the “footballer phase” which is whitish with black saddles, a yellow caudal peduncle and yellow fins; and a greyish form with a dark head, five dark saddles along the back, and small blue spots on the body.
A voracious piscivore inhabiting coral-rich areas of lagoon and seaward reefs, this fish is encountered most frequently in channels and outer shelf reefs. It feeds mostly on fishes, and occasionally on crustaceans. The prey comprises of a variety of large reef fishes, including groupers, and this diet of large fishes is responsible for the high concentrations of ciguatera toxins.
