Depending on its habitat, the black grouper may be olive, gray, or reddish-brown or black in color. It has black and copper, almost rectangular spots. It can pale or darken until its markings are barely visible. He has a thin pale fringe on the pectoral fins, a broad black edge and a thin white edge on the tail, sometimes a narrow orangish edge on the pectoral fin. The tail tips and soft dorsal and anal fins are bluish or black. The black grouper has a square tail and a smoothly rounded gill cover.
Black grouper are found from Bermuda and Massachusetts to southern Brazil, including the southern Gulf of Mexico, occasionally in the Florida Keys, the Bahamas, Cuba, and throughout the Caribbean. Adults are unknown on the northeastern coast of the United States.
