身體與鰭淡紅的; 臀鰭與尾鰭的較下面的部位有白色邊緣了。
Inhabit rocky or sandy bottoms; individuals descending to greater depths with growth. The stocks migrate seasonally between the coast and deeper waters in accordance with local hydrographic conditions and their life cycle. Feed mainly on fish and crustaceans; the young on plankton (Ref. 3688). Gonochorists (Ref. 4781).
棲息於岩石的或砂質底部; 隨著成長個體下降到較大的深度。 族群符合地方水道學的環境與他們的生命周期季節性地在海岸與較深的水域之間移動。 主要吃魚與甲殼動物; 幼魚捕食浮游生物。 (參考文獻 3688)
