生態学
海 底生の漂泳性; 深さの範囲 0 - 30 m (Ref. 6885). Temperate; 59°N - 14°N, 136°W - 93°W

サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 18.0 cm TL オス/雌雄の選別がない; (Ref. 2850); 最大記録サイズ: 9 年 (Ref. 56049)
背面の脊椎 (合計) : 24 - 27; 背鰭 (合計) : 9 - 10; 肛門の骨: 1; 臀鰭: 9. Spinous dorsal represented by a series of small spines, free from membrane; soft dorsal fin triangular and placed well back on body; caudal fin small and finely forked; anal fin spine small and broad, the fin mirroring the soft dorsal fin; pectorals truncate (Ref. 6885). Pale mottled brown, varying from olive green to yellow brown dorsally; creamy white ventrally; a bright silvery patch between operculum and pectorals extending to throat and bounded above by a dark band that extends forward through eye to snout; breeding males with bright red snout and phosphorescent snout (Ref. 6885).
Found in kelp beds, eelgrass, rocky areas, and over sand bottoms (Ref. 2850). Usually near the surface in schools, sometimes in dense schools well offshore (Ref. 2850). Feeds on small crustaceans and fish larvae (Ref. 6885). Minimum depth reported taken from Ref. 57178.
Nest is built, usually in kelp. Males are territorial (Ref. 6885) and guard the nest.
