دريايي وابسته به آب سنگ; تغييرات عمق 10 - 40 m (Ref. 5222). Subtropical; 33°N - 29°S, 98°W - 33°W (Ref. 5222)
Western Atlantic: southern Florida (USA) and the Gulf of Mexico to Brazil. It was suggested that Mycteroperca tigris was a transient species in the northwestern Gulf of Mexico, but has recently become abundant on the Flower Garden Banks off Texas (Ref. 6887).
Length at first maturity / Size / Weight / سن
Maturity: Lm 46.0, range 34 - ? cm
Max length : 101 cm TL جنس نر / بدون خواص جنسي; (Ref. 26340); common length : 40.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 5217); بيشينه وزن گزارش شده: 10.0 kg (Ref. 5222)
خارهاي باله پشتي (کل) : 11; شعاع نرم باله پشتي (کل) : 15 - 17; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 11. Distinguished by the following characteristics: Back crossed by about 11 pale narrow lines that slope downward and forward. No other grouper in the Caribbean has the same pattern of narrow pale diagonal lines (Ref. 26938). Further characterized by having depth of body contained 3.1-3.6 times in SL; head length 2.5-2.8 times in SL; flat interorbital area; rounded preopercle, without lobe at angle; diameter of posterior nostrils 3-5 times larger than anterior ones; large teeth, well developed canines (Ref. 89707).
A solitary species (Ref. 26340) occurring in coral reefs and rocky areas. It is considered an ambush predator that hides among the coral and sponges and is easy to approach. Frequents cleaning stations (Ref. 9710). The size versus sex distribution of Bermuda population indicates that this species is a protogynous hermaphrodite; all fish less than 37 cm TL were females and all fish larger than 45 cm TL were males (Ref. 6886). Randall (Ref. 33) reported food of 59 specimens 15 to 57 cm SL were purely fishes of a variety of species.
