Distinguished by the following characteristics: Head and body have oval groups of dark spots; outer third of pectoral fin bright yellow (Ref. 26938); two color morphs: a deep-water reddish form and shallow-water greenish form; depth of body contained 2.9-3.2 times in SL; head length 2.6-2.9 times in SL; convex interorbital area; evenly rounded preopercle or with slight notch, without projecting bony lobe at the angle; nostrils subequal or posterior nostrils with diameter twice the size of anterior nostrils (Ref. 89707).
頭部與身體有橢圓形群體的深色斑點; 胸鰭的外面第三個鮮黃色的.(參考文獻 26938)

生物學特性     字彙 (例如 epibenthic)

Adults found on rocky and coral reefs, juveniles occur in shallow turtle grass beds. Also been taken in trawls over mud bottom in the northern Gulf of Mexico. Feeds mainly on fishes (mostly on coral reef species) and squids. Although often implicated in ciguatera poisonings, it is a desirable food fish; and even large (5 to 10 kg) fish from areas considered safe are sold in markets. Also caught with surface trolling. Sex-reversal has been observed (Ref. 5521).

成魚發現於岩石與珊瑚礁.,稚魚出現在水淺的泰來海藻床。 也在墨西哥灣北部被採自在泥底上的拖網。 主要吃魚 (大部份在珊瑚礁種上) 與烏賊。 雖然時常關係到熱帶海魚中毒, 它是一個令人滿意的食用魚; 甚至認為保險箱的來自區域的大的 (5 到 10 公斤) 魚被賣在市場中。 也用表面的拖釣捕獲。 性別-反轉已經被觀察.(參考文獻 5521)
