Nassau groupers range from tawny to pinkish red in color, and they can change coloration based on mood and behavior. They display five dark, unevenly spaced bars across their body, and a distinctive bar runs from the snout to the dorsal fin. Also characteristic of Nassau groupers is a large black spot at the base of the tail. In juveniles, the caudal fin is rounded, whereas adults display a truncated fin characteristic of groupers. Nassau groupers can grow up to 1.2 m in length, though more commonly they grow between 8 and 72 cm (average 32 cm). They weigh between 2 and 27 kg (average 12 kg).
