Description

The Warsaw grouper is a very large grouper of the family Serranidae from the western Atlantic. The species grows to about 2.3 metres and can weigh hundreds of kilos; it has a robust, dark-brown body with a tall second dorsal spine. Adults live solitarily, usually on rocky bottoms and deep ledges well offshore; juveniles are sometimes found shallower. As an ambush predator it engulfs fishes, crabs and lobsters with its enormous mouth. The species grows slowly and becomes very old, making it vulnerable to overfishing, and is listed as Near Threatened (NT). Large specimens can contain ciguatera.
