简单描述

背棘 (总数) : 3; 背的软条 (总数) : 23 - 26; 臀鳍软条: 20 - 22; 脊椎骨: 32 - 35. Narrow interorbital distance (29-65 thousandths of SL), usually less than the diameter of the orbit (60-104 thousandths of SL), versus usually equal to or wider than the orbit diameter in other Opsanus species. Similar to O. phobetron, both usually have the posterior part of lower half of the mouth darkly pigmented in specimens over 7 cm SL. Upper lateral-line papillae 26, lower 23. Pectoral fin glands 12, starting between uppermost 2 pectoral fin-rays (Ref. 41041).
狭窄的眼间距 (29-65/SL*1000), 通常少于眼窝 (60-104/SL*1000) 的直径, 对通常等于或者比其他的 Opsanus 种的眼窝直径宽。 类似 O. phobetron, 两者都通常有暗被有颜色在超过 7 公分 SL 的标本中的嘴巴的下半部的后面的部份。 上面的侧线乳突 26, 低的 23. 胸鳍腺 12, 起点在最上面的 2 个胸鳍鳍条之间.(参考文献 41041)
