生態學
海洋 礁區魚類; 深度上下限 5 - 30 m (Ref. 9342). 亞熱帶的; 33°N - 23°N, 119°W - 106°W (Ref. 5222)
Eastern Central Pacific: southern La Jolla, California, USA to Mazatlan, Mexico.
中太平洋東部: 南方的加州拉賀亞, 美國到墨西哥馬瑞它。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 198 cm TL 雄魚/尚未辨別雌雄; (Ref. 2850); 最大體重: 91.0 kg (Ref. 5222)
背棘 (總數) : 11; 背的軟條 (總數) : 16 - 17; 臀棘: 3; 臀鰭軟條: 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).
發現於岩礁與海藻床了。 稚魚在被帶的加州水域與少數曾經的大的成魚是未知的可能有從一個比較向南的繁殖族群遊離棲地。 大的成魚吃魚。 (參考文獻 9342) 報告捕食幼年的雙髻鯊。 它的巨大的體型使它成為一個遊釣魚類的目標。 (參考文獻 9342)
