समुद्री ड़िमरसल; गहराई सीमा 30 - 525 m (Ref. 5222), usually 100 - 200 m (Ref. 5222). Subtropical; 41°N - 27°S, 98°W - 34°W (Ref. 5222)

Length at first maturity / आकार / वज़न / Age
Maturity: Lm 54.0, range 47 - ? cm
Max length : 122 cm TL पुल्लिंग / अलिंग; (Ref. 26340); common length : 60.0 cm TL पुल्लिंग / अलिंग; (Ref. 5217); अधिकतम प्रकाशित वज़न: 30.0 kg (Ref. 5222); अधिकतम सूचित उम्र: 27 वर्षो (Ref. 3090)
पृष्ठीय रीढ़ (सम्पूर्ण): 11; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 13-15; गुदा कांटा 3; ऐनल सौफट रेज़: 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).
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).
