生物學特性     字彙 (例如 epibenthic)

Adults are benthopelagic over continental shelves (Ref. 5217). Rare in oceanic insular areas (Ref. 5217). Juveniles associate with the jellyfish Chrysaora lactea in Southwestern Atlantic. Preyed on by juvenile comb grouper (Mycteroperca acutirostris) when protection given by the jellyfish fails (Ref. 52493). Adults are found often in schools. They feed on small invertebrates. Marketed fresh locally and considered a good food fish (Ref. 9626). In southern Brazil, stocks are found in 147 m deep water (Ref. 47377).

海岸的大洋性與底棲的大陸棚之上.(參考文獻 5217) 稀有的在大洋性的島區域中.(參考文獻 5217) 稚魚在大西洋西南部與水母 Chrysaora lactea 聚集在一起。 被幼年的頭梳被提供藉由水母的保護失敗的鱸科魚類 ( Mycteroperca acutirostris) 捕食了。 (參考文獻 52493) 常形成魚群。 吃小型無脊椎動物。 地方性地在市場上銷售生鮮地而且被認為是一個好食用魚。 (參考文獻 9626) 在巴西南部發現於 147 公尺深。 (參考文獻 47377)
