簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 80; 臀鰭軟條: 52. M. isaacsi differs from all other species of the genus by the following combination of characters: head long with elongate snout and almost straight jaw, skull length 7.0% TL, rostral fang strongly hooked with distal part in a nearly right angle to dorsal profile of skull, anterior dorsal fin ray above myomere number 13, jaw with 4 teeth, max depth of body 9.7% TL, and skin uniformly brown (Ref. 34506).
M. isaacsi 在組合特徵之後有別於所有的其他種的本屬藉由: 頭部長的具有延長的吻部與幾乎直的頜，頭蓋骨長度 7.0% TL ，嘴的尖牙強烈地以末梢部的部份鉤住在一幾乎對頭蓋骨，前面的背鰭鰭條上方 13 號 myomere 的背面輪廓的直角, 頜有四個齒，身體 9.7% TL 的最大深度與皮膚全身褐色的.(參考文獻 34506)
