Maturity: Lm ? range ? - ? cm
Max length : 66.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55763); common length : 30.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 55763); 最大體重: 1.6 kg (Ref. 53696)
Usually solitary. Constantly swims over rocky reefs, boulder strewn slopes and along walls. Occurs more commonly in shallow water (Ref. 5227). Feeds on algae and invertebrates (Ref. 28023).
通常獨居性的。 不斷地游泳岩礁之上, 圓石散佈的斜坡而且沿著牆壁。 在淺水區中更通常生存。 (參考文獻 5227) 吃藻類與無脊椎動物。 (參考文獻 28023)
