Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 25.0 range ? - ? cm
Max length : 76.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5222); common length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5217); 最大體重: 25.0 kg (Ref. 5217); 最大年齡: 22 年 (Ref. 31471)
背棘 (總數) : 11; 背的軟條 (總數) : 15 - 16; 臀棘: 3; 臀鰭軟條: 8. Scales cycloid except for a ctenoid patch of variable size in the pectoral region. Greenish gray to light brown on the back grading to white ventrally, with numerous well-spaced dull orange-red to brown spots on the head, body and fins. Five faint diagonal bars formed by darker spots on the sides. No saddle-shaped blotch on caudal peduncle or along base of dorsal fin (Ref. 26938); further characterized by having body depth contained 2.7-3.1 times in standard length; head length 2.3-2.4 times in standard length; evenly serrate preopercle, without salient angle; posterior nostril larger than anterior nostril (Ref. 89707).
鱗片圓形的在胸的區域中除了一個可變大小的有櫛鱗小區塊。 灰綠色到淡褐色在背部上漸層色到腹側白色的, 有很多的在頭部，身體與鰭上有些間隔暗橘紅色到褐色的斑點。 五條模糊的斜橫帶側邊上由較黑的斑點形成了。 沒有鞍斑-形狀的斑塊在尾梗上或者沿著背鰭基底.(參考文獻 26938)
Found in shallow reefs and rocky bottoms. Usually solitary
and territorial. Feed mainly on crabs (Calapa and
Mithrax) and other crustaceans (alpheid shrimps and
scyllarid lobsters), fishes (labrids and haemulids), and
octopus. Some undergo sexual inversion at 28 cm TL; most
fish larger than 40 cm are males. Important in terms of
numbers caught and total weight of landings in the Caribbean.
Easily approached by divers (Ref. 9710). Hermaphrodite
species. Excellent food fish (Ref. 26938). Readily caught
on hook and line and easily speared (Ref. 13442).
發現於淺水礁區與岩石底部了。 通常獨居性的與領域性。 主要吃螃蟹 ( Calapa 與 Mithrax) 與其他的甲殼動物 (槍蝦與 scyllarid 龍蝦) ，魚 (隆頭魚科的魚與 haemulids) 與章魚。 一些在 28 公分TL 歷經性別轉換; 大多數的魚大於 40 公分是雄性。 重要的根據捕獲數與卸魚重量的總重量在加勒比海。 藉著潛水者容易接近。 (參考文獻 9710) 雌雄同體種。 優良的食用魚.(參考文獻 26938) 輕易地在一支釣上面捕獲而且容易地獵殺了。 (參考文獻 13442)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Females rest on or close to the bottom, while males patrol around an area that consists of 1 to 5 females and defend this territory from other males. Form aggregation and reproduce almost exclusively within the aggregation period (Ref. 8557).西大西洋: 美國北卡羅萊那州到 Paraiba 巴西.(參考文獻 57756) 在西印度群島 Epinephelus 的最普遍種。
