Maturity: Lm ? range ? - ? cm
Max length : 198 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2850); 最大体重: 91.0 kg (Ref. 5222)
背棘 (总数) : 11; 背的软条 (总数) : 16 - 17; 臀棘: 3; 臀鳍软条: 10 - 11. Distinguished by the following characteristics: uniform dark brown or grey color of adults (can rapidly change into juvenile pattern when disturbed or under stress), large adults with white pectoral fin margin and median fins with narrow white edge; juvenile with greyish brown color, with dark spots along upper half of the body; depth of body 3.1-3.4 times in SL; head length 2.5-2.7 times in SL; rounded preopercle, finely serrate, lacking distinct lobe at the angle; posterior nostrils not notably enlarged, diameter less than twice of anterior nostrils (Ref. 89707).
Found in rocky reefs and kelp beds. Juveniles are unknown in California waters and the few large adults that have been taken there are probably expatriates from a more southerly breeding population. Large adults feed on fishes (Ref. 9342). Reported to prey on juvenile hammerhead sharks. Its large size makes it an object of game fishing (Ref. 9342).
发现于岩礁与海藻床了。 稚鱼在被带的加州水域与少数曾经的大的成鱼是未知的可能有从一个比较向南的繁殖族群游离栖地。 大的成鱼吃鱼。 (参考文献 9342) 报告捕食幼年的双髻鲨。 它的巨大的体型使它成为一个游钓鱼类的目标。 (参考文献 9342)
