生物學特性     字彙 (例如 epibenthic)

Lives in coastal waters at shallow depths, generally from 10-20 m, more seldom from 75-100 m, on rocky bottom with seaweeds. Solitary and secretive, undertakes only limited local movements. Spawns from May to September at 50-70 m depth near the shore throughout its entire range. Feeds on sea stars, crustaceans, worms, mollusks and small fish (Ref. 1371).

在深度淺的地方生活在沿岸水域, 通常從 10-20 公尺, 更很少從 75-100 公尺, 在岩石的底部上有海草的地方。 獨居性與躲躲藏藏的, 進行只有有限制的地方運動。 在它的整個範圍各處在海岸附近的 50-70 公尺深從五月到九月產卵。 吃海星,甲殼動物,蠕蟲,軟體動物與小魚。 (參考文獻 1371)
