简单描述
型态特徵 | 形态测量图
背棘 (总数): 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.
在下面上的吻与狭窄的 ventromedian 长条的腹面前缘裸露的, 头部不一样地鳞片覆盖完整。 鳞片易脱落的, 有小的, 在 6 到 9 平行的列中短又锥形小刺。 整体的色彩是褐色的到蓝色的; 躯干蓝色的到黑色的; 鳍黑色的; 嘴暗色的; 鳃腔黑色的。
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).
显然地在它的分布范围的北部中更深地发现。 桡脚类的动物 (80%) 与多毛类动物 (62%) 有调查从斜坡的标本外海的非洲西北部中最高的比例。 其他的甲壳动物与一些鱼形成那其余的食性。 这种类似多数的 macrourines, 仰赖一个底栖与大洋性生物的混合食性.(参考文献 6219)
