简单描述 型态特徵 | 形态测量图

背的软条 (总数): 130-150; 臀鳍软条: 110 - 130. M. boehlkei differs from all other species of the genus by the high number of anal fin rays (110-130 vs. 42-88) and by an obtuse angle between rostral fang and frontal profile of skull. It is further distinguished by the following combination of characters: head short, snout blunt, skull length4.2-5.2% TL, rostral fang with dorsal profile slightly concave, anal fin origin below dorsal fin rays number 7-13, pectoral fin 2-3% TL, lower jaw nearly straight, and 6 lateral, subdermal spots of pigmentation (Ref. 34506).
M. boehlkei 有别于所有的其他种的本属藉由高数字臀鳍棘条 (110-130 vs.42-88) 与藉着在嘴的尖牙与头盖骨的前轮廓之间的一个圆头角。 它是进一步藉着下列的组合特徵区别: 头部短, 吻钝的, 头盖骨长度 4.2-5.2% TL, 嘴的尖牙用背面轮廓些微地凹曲, 臀鳍起源在背鳍鳍条之下数 7-13 ,胸鳍 2-3% TL ,下颌几乎是直的, 与 6个侧面又皮下颜色的斑点.(参考文献 34506)

All specimens were taken in closing nets, one between 2500 and 3500 m with a bottom depth of 4563 m and the other specimens between 10-3- m above the bottom with soundings from 2960-5430 m (Ref. 34506).

所有的标本被用闭合网采集, 在 2500 与 3500 公尺之间的一底部深度在 10-3 之间的 4563 公尺与另一个标本- 具有来自 2960-5430 公尺的测锤测得的结果在底部上面的公尺.(参考文献 34506)
