Dusky grouper

Epinephelus marginatus (Latin pronunciation: [epiːˈnepʰelus marɡiˈnaːtus]), the dusky grouper, yellowbelly rock cod or yellowbelly grouper, is a species of fish in the grouper family, Epinephelidae. It is found in coastal waters, primarily at the edges of the Atlantic Ocean – off western Africa and eastern South America – and also in the Indian Ocean around South Africa, Madagascar and Réunion, and throughout the Mediterranean.

Habitat

Epinephelus marginatus is demersal, normally found in and around rocky reefs from surface waters down to as much as 300 metres (980 ft) in depth. It often occurs in the vicinity of beds of Posidonia sea grass. Juveniles are generally found more inshore than the adult fish, even being found in rock pools. Where they are protected, in marine nature reserves and no take zones, both adults and juveniles occur in shallow waters, but the depths at which juveniles are found is always shallower than the preferred depths of adults.

Distribution

Epinephelus marginatus has two disjunct distribution centres, the main one is in the eastern Atlantic from the west coast of Iberia south along the western coast of Africa to the Cape of Good Hope, extending east into the south-western Indian Ocean, as far as southern Mozambique, with doubtful records from Madagascar and possibly Oman. It is found throughout the Mediterranean too. The second population occurs in the south western Atlantic off the coast of South America in southern Brazil, Uruguay and northern Argentina. In the eastern Atlantic it is not normally found further north than Portugal but there have been rare records from the Bay of Biscay and in the English Channel as far north as northern France, Great Britain and Ireland.
