Coral Trout range in colour from pink to red to brown, with small brilliant blue spots over the body and head. Coral trout are beautifully marked, robust, predatory reef fish of tropical waters. They belong to the same large group of grouper-like fish as the tropical Australian saltwater cods (Serranidae). Coral trout have large mouths and sharp, widely-spaced canine teeth. Colouration varies between species and locations; from greenish-brown in shallow water, through brick-red to bright red in deeper water, but always with an overlay of blue or red spots. The eye is red around an elongated pupil.
