背棘 (总数) : 11; 背的软条 (总数) : 16 - 18; 臀棘: 3; 臀鳍软条: 10 - 12. Distinguished by the following characteristics: adult females and juveniles are generally brownish grey with dark vermiculations; camouflage phase has 5 dark brown saddles separated by short white bars below the dorsal fin; large males sometimes display a "black-belly" and "black-back" phase; black-belly phase is mostly pale grey, with faint dark reticulations below soft dorsal fin, belly and ventral part of the body above anal fin black, as are margin of the soft dorsal fin, central rear part of caudal fin and rear margins of pectoral and pelvic fins; depth of body contained 3.0-3.5 times in SL; head length 2.5-2.7 times in SL; convex interorbital area; angle of preopercle produced into a rounded lobe bearing enlarged serrae; posterior nostrils of adults much larger than anterior ones; smooth lateral body scales, except those covering pectoral fin (Ref. 89707).
Body shape (shape guide): fusiform / normal.
Body shape (shape guide): fusiform / normal.
Juveniles occur in estuaries and seagrass beds; adults are usually found offshore on rocky bottom (rarely to 152 m), occasionally inshore on rocky or grassy bottom. It is the most common grouper on rocky ledges in the eastern Gulf of Mexico. Adults are either solitary or in groups of 5 to 50 individuals; feed mainly on fishes, some crabs, shrimps, and cephalopods. Juveniles (less than 20 cm) feed mainly on crustaceans that live in shallow grass beds.
稚鱼出现在河口与海草床; 成鱼通常在岩石的底部 (很少地对 152 公尺) 上被发现于外海, 偶然地在沿海的岩石或长满草的底部。 它是在墨西哥湾东方中的岩石岩架上最普遍的鲈科鱼类。 成鱼是单独出现或形成 5 到 50个个体的群体; 主要捕食鱼，一些螃蟹，虾与头足类动物。 稚鱼 (少于 20 公分) 主要捕食生活于水浅的草床的甲壳动物。
