Max length : 64.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9348); common length : 30.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9348)
背棘 (總數) : 0; 背的軟條 (總數) : 11 - 13; 臀棘: 0; 臀鰭軟條: 12 - 15; 脊椎骨: 60 - 63. Most species are brown to gray or red dorsally and laterally and pale ventrally; some species have a pattern of dusky saddles, lateral spots, or bars (Ref. 35938).
Perch motionless on pectoral fins in a wide range of habitats; commonly found on sandy bottoms or sand patches around rocky reefs and boulder and gravel strewn slopes. Active during the day. May bury in sand with only the eyes and mouth protruding (Ref. 5227). Feed on fishes (Ref. 9348). Oviparous, with planktonic eggs and larvae (Ref. 35938). Extended larval period (Ref. 35938).
