Western Central Atlantic: Gulf of Mexico and east coast of US from North Carolina to Key West and along the southern shore of the Caribbean Sea. Juveniles are occasionally found as far north as Massachusetts.
Found over ledges and high-relief rocky bottoms in the eastern Gulf of Mexico; at low-profile bottoms at depths of 30 to 100 m in North Carolina; this species was the most abundant grouper in areas of living Oculina coral formations at depths of 70 to 100 m off the east coast of Florida. This species apparently moved inshore when bottom temperature fell below 8.6°C. Juveniles found in shallow water at jetties and in mangrove areas.
