簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2; 臀棘: 0. Ventral leading edge of snout and narrow ventromedian strip on underside naked, head otherwise completely scaled. Scales deciduous, with small, short, conical spinules in 6 to 9 parallel rows. Overall color is brownish to bluish; trunk bluish to blackish; fins blackish; mouth dusky; gill cavities blackish.
Body shape (shape guide): elongated; Cross section: oval.
在下面上的吻與狹窄的 ventromedian 長條的腹面前緣裸露的, 頭部不一樣地鱗片覆蓋完整。 鱗片易脫落的, 有小的, 在 6 到 9 平行的列中短又錐形小刺。 整體的色彩是褐色的到藍色的; 軀幹藍色的到黑色的; 鰭黑色的; 嘴暗色的; 鰓腔黑色的。
Apparently found deeper in the northern part of its range. Copepods (80%) and polychaetes (62%) have the highest proportions in specimens examined from the slope off northwestern Africa. Other crustaceans and a few fish formed the remainder of the diet. This species like the majority of macrourines, depends on a mixed diet of benthic and pelagic organisms (Ref. 6219).
顯然地在它的分佈範圍的北部中更深地發現。 橈腳類的動物 (80%) 與多毛類動物 (62%) 有調查從斜坡的標本外海的非洲西北部中最高的比例。 其他的甲殼動物與一些魚形成那其餘的食性。 這種類似多數的 macrourines, 仰賴一個底棲與大洋性生物的混合食性.(參考文獻 6219)
