簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 3; 背的軟條 (總數) : 23 - 26; 臀鰭軟條: 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).
狹窄的眼間距 (29-65/SL*1000), 通常少於眼窩 (60-104/SL*1000) 的直徑, 對通常等於或者比其他的 Opsanus 種的眼窩直徑寬。 類似 O. phobetron, 兩者都通常有暗被有顏色在超過 7 公分 SL 的標本中的嘴巴的下半部的後面的部份。 上面的側線乳突 26, 低的 23. 胸鰭腺 12, 起點在最上面的 2 個胸鰭鰭條之間.(參考文獻 41041)
