Potato cod (Epinephelus tukula). This large fish, also known as the potato grouper or potato bass, is actually a grouper. It is found near reefs in the Indo-Pacific, where it feeds on other fish and crustaceans. It is highly territorial, and will often attack intruders who stray into its patch of the reef. Photographed at Cod Hole on North Ribbon reef in the Great Barrier reef, Coral Sea, Australia.
