Etymology: Mycteroperca: Greek, mykter, -eros = nose + Greek, perke = perch (Ref. 45335); phenax: Most probably a misspelling of the specific epithet because based on Labrus guaza Loefling 1758:104 (type locality: Cumana, Venezuela) (see CofF)..

生态学
海洋; 半咸淡水 礁区鱼类; 海洋洄游的 (Ref. 51243); 深度上下限 30 - 100 m (Ref. 5222), usually 30 - 100 m (Ref. 5222). 亞熱帶的; 41°N - 8°N, 98°W - 25°W (Ref. 5222)
Western Central Atlantic: Gulf of Mexico and east coast of US from North Carolina to Key West and along the southern shore of the Caribbean Sea. Juveniles are occasionally found as far north as Massachusetts.
中西大西洋: 來自北卡羅萊那州到的墨西哥灣與美國的東海岸調音西方而且沿著加勒比海的海岸南部。 稚魚偶然地被發現向北遠至麻薩諸塞州。

Maturity: Lm 33.2 range ? - ? cm
Max length : 107 cm TL 雄鱼/尚未辨别雌雄; (Ref. 89707); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3708); 最大体重: 14.2 kg (Ref. 40637); 最大年龄: 21 年 (Ref. 6846)
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: four color patterns, first is brown phase with head and body pale brown covered with small reddish brown spots that extend onto median fins, second is cat's paw phase with pale brown body color with dorsolateral parts of body having several clusters of dark brown spots resembling the paw print of a cat, third is with large adults with grey-head phase with the rear two-thirds of the body dark, head and body anterior to the 6th dorsal-fin spine in silvery grey with dark reticulations and fourth is bicoloured phase with pale brown anteriorly and abruptly dark chocolate brown posteriorly; depth of body contained 3.0-3.4 times in SL; head length 2.6-3.0 times in SL; convex interorbital area; angular preopercle, angle with distinct bony lobe; serrate interopercle and subopercle; posterior nostrils of adults 2-4 times larger than anterior ones (Ref. 89707).
Found over ledges and high-relief rocky bottoms in the eastern Gulf of Mexico; at low-profile bottoms at depths of 30 to 100 m in North Carolina; this species was the most abundant grouper in areas of living Oculina coral formations at depths of 70 to 100 m off the east coast of Florida. This species apparently moved inshore when bottom temperature fell below 8.6°C. Juveniles found in shallow water at jetties and in mangrove areas.
在墨西哥湾东方中发现在岩架与深浮雕岩石底部上了; 在低矮的底部深度在北卡罗莱那州的 30 到 100 公尺; 这种是在活的 Oculina 珊瑚结构深度区 70 到 100个佛罗里达的公尺东岸外海中最丰富的鲈科鱼类。 当底部温度下降到 8.6个 ° C. 以下的时候，这种显然地向海岸移动了 稚鱼发现于浅水区了在突堤与在红树林区域中。
