簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 96; 臀鰭軟條: 66. M. ozawai differs from the other species of the genus by the following combination of characters: head short, snout blunt and short, skull length 5.5% TL, rostral fang with dorsal profile slightly convex forming an almost straight line with frontal profile of skull, dorsal fin origin above myomere number 5, anal fin origin below dorsal fin ray number 40 and pectoral fin about 1% TL.
M. ozawai 在組合特徵之後有別於本屬的另一個種藉由: 頭部短, 吻鈍且短的,頭蓋骨長度 5.5% TL, 嘴的尖牙用背面輪廓些微中凸形成一幾乎直線用頭蓋骨的前輪廓, 在 5 號 myomere 上面的背鰭起點, 臀鰭起源在背鰭 40 號鰭條與胸鰭之下大約 1% TL。
