خارهاي باله پشتي (کل) : 11; شعاع نرم باله پشتي (کل) : 13 - 15; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 9. Distinguished by the following characteristics: Dark margin on spiny dorsal fin and dark saddle on caudal peduncle that extends below lateral line (Ref. 26938); juveniles with pale yellow caudal and pectoral fins; black saddle blotch on the caudal peduncle reaching below lateral line; depth of body contained 2.4-2.8 times in SL; head length 2.2-2.4 times in SL; convex interorbital area, width less than or subequal to eye diameter; enlarged serrae at angle of preopercle; distinctly convex upper edge of operculum; posterior nostrils 2-5 times larger than anterior nostrils (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Adults occur well offshore on rocky bottoms. Juveniles may be found inshore and are often reported from the northeastern coast of the U.S (Ref. 89707). Adults feed on fishes, gastropods, cephalopods, and brachyuran crustaceans (Ref. 5222). Valuable commercial food fish (Ref. 26938).

The size (76.7-109 cm) and age (8-29 yr) of 97 male specimens and the capture of two specimens undergoing sex change provided conclusive
evidence that snowy grouper are protogynous hermaphrodites (Ref. 45886).
