Etymology: Bembrops: Greek, bembras, -ados = a kind of anchovy m+ Greek, ops = appearance (Ref. 45335); heterurus: Specific name probably from the Greek 'heteros' meaning different and 'oura' meaning tail..
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 居于水底的; 深度上下限 50 - 400 m (Ref. 6948), usually 80 - 200 m (Ref. 47377). 深水域; 12°N -
Western Atlantic: off Rio de Janeiro, Brazil to Uruguay. Eastern Atlantic: Mauritania to the extreme northern waters of Namibia (Ref. 6948, 27121). The eastern Atlantic form referred to as Bembrops heterurus is unlikely to be conspecific with the Brazilian form, thus further taxonomic study is needed to clarify this situation (Ref. 6948).
西大西洋: 外海的巴西里約熱內盧到烏拉圭。 東大西洋: 茅利塔尼亞到那米比亞的極端北方水域.(參考文獻 27121) 被歸屬於 尾斑掛帆鱚〔Bembrops heterurus〕 的東大西洋形式不可能是同種巴西的形式,如此進一步的分類澄清被需要。
