背棘 (總數) : 11; 背的軟條 (總數) : 16 - 18; 臀棘: 3; 臀鰭軟條: 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.
稚魚出現在河口與海草床; 成魚通常在岩石的底部 (很少地對 152 公尺) 上被發現於外海, 偶然地在沿海的岩石或長滿草的底部。 它是在墨西哥灣東方中的岩石岩架上最普遍的鱸科魚類。 成魚是單獨出現或形成 5 到 50個個體的群體; 主要捕食魚，一些螃蟹，蝦與頭足類動物。 稚魚 (少於 20 公分) 主要捕食生活於水淺的草床的甲殼動物。
