Monognathidae (Onejaws)
單頜鰻科 (Onejaws)
Etymology: Monognathus: Greek, monos = one + Greek, gnathos = jaw (Ref. 45335); boehlkei: Named for the late James E. Böhlke in recognition of his valuable contributions to the study of apodal fishes.
Eponymy: James Erwin Böhlke (1930–1982) and his wife Eugenia Louisa Böhlke née Brandt (1929–2001) were both ichthyologists who worked at the Academy of Natural Sciences of Philadelphia, where he was Curator of Ichthyology (1954–1982). [...] (Ref. 128868), visit book page.

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 130 - 150; 臀鰭軟條: 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 有別於所有的其他種的本屬藉由高數字臀鰭棘條 (110-130 vs.42-88) 與藉著在嘴的尖牙與頭蓋骨的前輪廓之間的一個圓頭角。 它是進一步藉著下列的組合特徵區別: 頭部短, 吻鈍的, 頭蓋骨長度 4.2-5.2% TL, 嘴的尖牙用背面輪廓些微地凹曲, 臀鰭起源在背鰭鰭條之下數 7-13 ，胸鰭 2-3% TL ，下頜幾乎是直的, 與 6個側面又皮下顏色的斑點.(參考文獻 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).
所有的標本被用閉合網採集, 在 2500 與 3500 公尺之間的一底部深度在 10-3 之間的 4563 公尺與另一個標本- 具有來自 2960-5430 公尺的測錘測得的結果在底部上面的公尺.(參考文獻 34506)
