определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 80; членистые (мягкие) лучи анального плавника: 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).
