生態學
海洋 深海區的. 深水域; 50°N - 35°S
Eastern Atlantic: between Ireland and the Azores; Canary Islands to South Africa but not recorded from the Gulf of Guinea. Western Atlantic: off Bermuda. Also known from northwest Pacific. Leptostomias gracilis, Leptostomias macropogon, Leptostomias longibarba, Leptostomias bermudensis, Leptostomias analis and Leptostomias leptobolus are probably synonyms of a single species (the entire complex needs a thorough study, Ref. 4468).
東大西洋: 在愛爾蘭與亞速群島之間; 加納利群島到南非但是沒有紀錄從幾內亞灣。 西大西洋: 外海的百慕達群島。 也已知來自西北太平洋。 纖巨口魚〔Leptostomias gracilis〕 ， 大鬚纖巨口魚〔Leptostomias macropogon〕 ， 長鬚纖巨口魚〔Leptostomias longibarba〕 , Leptostomias bermudensis,Leptostomias analis 與 Leptostomias leptobolus 可能是種的同種異名.(整個的複合體需要一個完全的研究, 參考文獻 4468)
