Maturity: Lm ? range ? - ? cm
Max length : 8.9 cm TL オス/雌雄の選別がない; (Ref. 2850)
背面の脊椎 (合計): 2 - 5; 背鰭 (合計): 4-5; 肛門の骨 0; 臀鰭: 4 - 5; 脊つい: 32. Dorsal fins small; caudal fin rounded; pectoral fins large, supported well out from sides of body; pelvic fins very narrow and rays appear fused (Ref. 6885). Color very variable, depending on background; brown with dark bars, orange with bluish bars, or scarlet with brown bars (Ref. 6885).
Inhabits intertidal areas and to 18 m depth (Ref. 2850). Frequently caught in tide pools (Ref. 28197). Its food consists mainly of tiny crustaceans (shrimp and crab-like creatures) which are picked from the bottom or very close to it (Ref. 4930). Demersal spawner in nearshore habitats (Ref. 56049).
