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).
鉴别: 大又看似掠食性的种; 非常大的嘴与大的矮胖齿; 眼在似乎之下非常小的被相较于的颊的覆有鳞片区域; 当在轮廓中看了，前颌骨的顶端的上表皮对于相当多的距离时常几乎水平地延伸。 (参考文献 55949)
描述: 非常大的头部与嘴; 下颌一般到强烈地凸出, 具有一个突出的神经突起; 眼小的; 颊的深; 齿大的﹐厚的, 非常直的而且分开很远; 时常只有当嘴巴被关闭的时候，在颌的前面附近的齿的顶端是看得见的。 (参考文献 55949)
体色 身体通常 countershaded; 腹面, 下巴与喉部的区域可能是銀灰色的, 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 55949)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.9 ±0.62 se; based on food items.
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (32 of 100).
