Western Atlantic: Bermuda and northwestern Gulf of Mexico to Brazil. Report of this species (as Serranus acutirostris) from the Canary Islands is probably a misidentification of Mycteroperca fusca.
西大西洋: 墨西哥灣西北部到委內瑞拉; 包括百慕達群島與巴西。 可能是一個 Mycteroperca fusca 的錯誤鑑定的這種 (當 Serranus acutirostris) 從加納利群島的報告.

背棘 (总数) : 11; 背的软条 (总数) : 15 - 17; 臀棘: 3; 臀鳍软条: 10 - 12. Distinguished by the following characteristics: greyish brown color of head and body with irregular white spots and blotches; 3-4 dark brown stripes radiating posteriorly from the eye and continuing along the ventral half of the body as wavy dark stripes; dark brown stripe from maxillary streak to edge of preopercle; darker median fins with white spots and streaks; oblong and compressed body, depth of body 2.7-3.2 times in SL; head length 2.5-2.7 times in SL; width of maxilla 4.4-5.8% of SL; convex interorbital area; angular preopercle, enlarged serrae at the angle, forming a weak lobe; subequal sizes of anterior and posterior nostrils (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Maximum depth from Ref. 126840. Juveniles inhabit turtle grass beds, mangrove areas, and shallow waters among soft corals and coral reefs. Adults are found on rocky bottoms with high relief. Probably feeds on plankton (no information is available on the food of this species). The max weight of 4 kg given in Ref. 5222 appears too low. The species is a popular game fish in southern Brazil for both spear fishermen and rod-and-reel anglers. Fish of 4-7 kg are common, with the spear fishing record at 10.1 kg (Capt. Eduardo Baumeier, pers. comm., 2001).
稚鱼栖息于在软珊瑚与珊瑚礁之中的泰来海藻床，红树林区域与浅水域。 成鱼用深浮雕栖息于岩石底部。 可能吃浮游生物。 (没有信息在这种的食物上是有用的) 4 公斤记录在参考文献 5222 的最大重量显得太低的。 此鱼种对于矛渔夫和甩竿垂钓者在巴西南部是一个受欢迎的游钓鱼类。 4-7 公斤的鱼是普遍, 与鱼矛渔法在 10.1 公斤记录 (Capt. Eduardo Baumeier ， pers. comm。,2001)。
