Found throughout the world, including various parts of the western Pacific, the Coral Trout can often be seen in and around the waters of the Great Barrier Reef, where they’re snacking on prawns, crustaceans and fish.
Here they display two distinct methods of hunting – ambush and prowling – which they do during daylight hours (most often at dusk and dawn). Interestingly, they also change their skin colour when feeding.
With the ambush technique, this prawn lover will hide, remaining quiet and still before attacking passing prey. With the prowling technique, the fish will creep toward their target before suddenly attacking at great speed.
