توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
شعاع نرم باله پشتي (کل) : 91 - 98; شعاع نرم باله مخرجي: 43 - 58. M. bertini differs from all other species of the genus by the great distance between anal fin origin and anus (13-19 myomeres). It is further distinguished by the following combination of characters: head short, snout relatively long, skull length 3.6-4.9% TL, rostral fang with dorsal profile slightly convex forming an almost straight line with frontal part of skull, dorsal fin origin above myomere number 5-7, pectoral fin 5.3-10.5% TL and no lateral, subdermal spots of pigmentation (Ref. 34506).
All specimens were caught in the water column far above the bottom (Ref. 34506).
