簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 72; 臀鰭軟條: 42. M. bruuni differs from all other species of the genus except M. jesperseni in having a glandular part of the dorsal fin. Is distinguished by the following combination of characters: head short, snout blunt, skull length 3.8% TL, rostral fang with dorsal profile slightly convex forming an almost straight line with frontal part of skull, dorsal fin origin above myomere number 13, and small pectoral fins (ca. 1% TL).
M. bruuni 在有一個方面除了 M. jesperseni 以外有別於所有的其他種的本屬腺部分的背鰭。 被藉著下列的組合特徵區別: 頭部短, 吻鈍的,頭蓋骨長度 3.8% TL, 嘴的尖牙用背面輪廓些微中凸形成一幾乎用頭蓋骨的前部份 , 在 13 號 myomere 上面的背鰭起點 , 與小的胸鰭 (大約 1% TL) 的直線.
Holotype was captured with a ringnet, at a depth of about 4000 m (Ref. 34506).
Holotype 被用一個環狀網捕獲, 深度大約 4000 公尺.(參考文獻 34506)
