Forms schools. Inhabits rocky bottoms down to depths of about 150 m, but especially abundant in the surf zone; young occur in Zostera seagrass beds. Prefers to feed on small crustaceans and mollusks; also takes seaweeds and corals (Ref. 3688).
形成鱼群。 栖息于岩石底部向下至深度大约 150 公尺, 但是尤其丰富的在海浪区中; 幼鱼出现在 Zostera 海草床。 偏爱觅食小型甲壳动物与软件动物; 也采取海草与珊瑚。 (参考文献 3688)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02042 (0.01136 - 0.03671), b=2.96 (2.81 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
营养阶层 (Ref.
69278): 3.1 ±0.45 se; based on food items.
Generation time: 7.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (tmax=12).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100).
