The Golden Grouper can be recognized by its brownish body and darker fins, with two distinctive dark lines on its head. One line runs from the lower edge of the eye to the ventral rear edge of the interopercle, and the other from the dark maxillary streak to the lower edge of the preopercle. Adults also exhibit a yellow blotch on their body below the spinous dorsal fin. The species has a robust body, grows up to 140 cm in length, and features 11 dorsal spines, 15-17 dorsal soft rays, 3 anal spines, and 8 anal soft rays. The body depth is less than the head length, with a convex interorbital area and an angular preopercle.
Golden Groupers are demersal, meaning they live close to the bottom of seas and oceans. They inhabit sandy, muddy, or rocky bottoms at depths ranging from 4 meters to 160 meters. These fish are known to migrate annually to the same sites, and juveniles often form small groups. Their range includes the entire Mediterranean basin and extends into the warmer waters of the Atlantic Ocean.
Golden Groupers primarily feed on other fish but also consume crustaceans and mollusks. A notable study on a female of 47 cm standard length estimated a total fecundity of 879,000 eggs. These groupers have unique physical traits, such as flat but distinct middle and lower opercular spines, and a straight or slightly convex upper edge of the operculum. Their maxilla reaches the vertical rear edge of the eyes, and the ventral edge of the maxilla has a low step, with no scales. Additionally, the lateral body scales are ctenoid with auxiliary scales in adults, and they have two rows of teeth on the midlateral part of the lower jaw.
Divers exploring Malta’s underwater sites have excellent opportunities to see the Golden Grouper. One notable location is the Inland Sea at Dwejra on Gozo’s west coast, near the famous Azure Window. At a depth of around 20 meters, divers can witness these remarkable fish thriving in their natural habitat amidst the island’s stunning marine landscapes. Malta’s best dive sites have diverse marine life and historical significance, provide a perfect setting for encountering the Golden Grouper and other fascinating marine species.
