Diagnosis: large, predatory-looking species; very large mouth and big stout teeth; eye seems very small compared to scaled area of cheek beneath; upper surface of the tip of the premaxilla often extends almost horizontally for a considerable distance when viewed in profile (Ref. 55949).
鑑別: 大又看似掠食性的種; 非常大的嘴與大的矮胖齒; 眼在似乎之下非常小的被相較於的頰的覆有鱗片區域; 當在輪廓中看了，前頜骨的頂端的上表皮對於相當多的距離時常幾乎水平地延伸。 (參考文獻 55463)
描述: 非常大的頭部與嘴; 下頜一般到強烈地凸出, 具有一個突出的神經突起; 眼小的; 深地的頰; 齒大的﹐厚的, 非常直的而且分開很遠; 時常只有當嘴巴被關閉的時候，在頜的前面附近的齒的頂端是看得見的。 (參考文獻 55463)
體色 身體通常 countershaded; 腹面, 下巴與喉部的區域可能是銀灰色的, 白色的或黃色; 兩性的成魚可能有白色的﹐灰色的或橘色的/黃色的腹鰭, 有時有黑色的蔓緣; 尾鰭深灰色的到黑色的, 在薄膜上有時具有白色的斑點; 在軟背鰭的薄膜上有時具有白色的斑點。 (參考文獻 55463)
