描述

provided by The Fish Database of Taiwan
身體延長,尾部側扁且漸細,頭部及身體佈滿黑色細點呈暗黑色,全長為鰓孔位體高及肛門位體高之21.0-29.3及18.9-27.9倍;肛門約位於全長前1/3處,肛門前長佔全長的23-28 %;尾長極度延長,其長度約為肛門前長的2.6-3.4倍;尾端柔軟,易彎折,尾部末端鰭條延長;背鰭起點位於胸鰭末端之後方;奇鰭為暗色,鰭條分節;具有胸鰭,位於體高中點之上方;鰓孔為黑色,形狀為圓形,位於身體側邊中點之下方,其上緣約與胸鰭基部下緣等高;全長為頭長之12.1-13.5倍,吻端圓鈍,口裂末端約位於眼睛水平中點,上顎明顯長於下顎,吻長大於或小於眼直徑,吻長為眼直徑之0.9-1.5倍;眼睛較小,約占頭長的12-17 %;嘴唇不具上唇瓣;前鼻孔為短管狀,靠近吻端,後鼻孔為圓形,約位於眼睛上緣前方。上眼窩有2個感覺孔,下眼窩有3個感覺孔,前鰓顎有3個感覺孔,顳骨接合處有1個感覺孔;背鰭前側線孔數15-16,胸鰭前側線孔數4-5,肛門前側線孔數32-33;背鰭前脊椎骨數14-20,肛門前脊椎骨數27-41,血管閉合處前脊椎骨數52-55,總脊椎骨數168-178。此種經常與(/M. brevirostris/)混淆,可藉由其體色、鰓孔形狀及背鰭起點來區分這兩種。本種與/M. brevirostris/主要差異在於腹部不具感覺孔。背部為灰棕色,並向下延伸至腹部;胸鰭較短,背鰭起點位於較後方,因此胸鰭末端遠在背鰭起點前方。
