Island Grouper juvenile
The Island Grouper, also called the Comb Grouper, is native to coastal reefs and rocks of Macaronesia (the Canary Islands, Madeira, Cape Verde Islands and the Azores). The adult fish is often brown mottled with white patches but colouring and patterns are variable. It grows to 80cm. It is said to be able to reverse its pattern to lighter with dark patches when stessed. Above may be juveniles. It is threatened by over-fishing in its coastal areas and by invasive introduced fish such as the European Seabass.
