The black grouper is a large marine fish of the perch-like order from the stone perch family. Another name for fish used in the Mediterranean is Meru.
The fish has a body of the correct oval shape and reaches one and a half meters in length. Brown color with gray streaks. Youth brown-violet or even lilac with marks of white and dark tones. Unpaired fins, usually edged with black. The head is full, with an upper slightly concave profile, with rough scales and sharp spines that become blunt with age. It lives on the continental shelf up to 1000 meters deep, but prefers rocky spurs at depths from 100 to 250 meters. Juveniles usually feed in surface waters on floating remains of benthos. The black grouper is a desirable object of sport fishing.
