Etymology: Heterodontus: heteros (Gr.), different; odontos (Gr.), tooth, referring to pointy teeth (for clutching prey) at front of jaws, different than rounded molar-like teeth (for grinding hard-shelled invertebrates) at the back (See ETYFish); omanensis: -ensis, Latin suffix denoting place: Gulf of Masira, Central Oman, Arabian Sea, type locality (See ETYFish).

简单描述
检索表 | 型态特徵 | 形态测量图
脊椎骨: 98. Diagnosis: Four dark saddles, more or less equally distributed along the head and body. Relatively small, dark pigmented dorsal fins, each with a white distal streak. Large pectoral fins. Unique egg case, with 2 long tendrils extending from its base and flanges with 2 turns. This species differs from H. japonicus in having 4 dark saddles (vs. 11-14); a smaller first-dorsal fin (9.3-10.9% TL vs. 11-21% TL); an egg case of 2 turns (vs. 3), bearing extremely long tendrils (vs. short) (Ref. 54826).
鉴别: 四个深色的鞍状斑, 约略同样地分布沿着头部与身体。 相当小又深色的背鳍, 每个具有一个白色的末梢部的条纹。 大的胸鳍。 独特的卵荚, 有两个从它的基底延伸的长的卷须，而且边缘有两个旋转。 这种有别于 H. japonicus 有 4个深色的鞍状斑;(vs.11-14) 一个较小的第一背鳍 (9.3-10.9% TL 和 11-21% TL 比较); 2 的卵荚旋转 (vs.3), 生长着非常长的卷须 (vs. 短).(参考文献 54826)
