生物学特性     字汇 (例如 epibenthic)

Observed often on steep rocky substrata off promontories at depths of 15 m or more. Feed on zooplankton, generally in small groups with individuals, as high as 5 m above the bottom (Ref. 39287). Diurnal species (Ref. 54980). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

在陡峭的岩石底层上时常观察外海的岬角深度 15个公尺或更多。 吃浮游动物, 通常形成小群鱼群和个体, 与 5 公尺上方底部一样高。 (参考文献 39287)
