脊椎骨: 109. Dorsal with irregular reticulated light brown to reddish-brown pattern over disc, pelvic fins and tail, demarcating white or creamy-white oval; reniform and circular spots of variable sizes over disc, and small white spots on dorsal and caudal fins. Eyes large and bulging. Circular spiracles with markedly elevated rims and complete antero-lateral margin. Interorbital distance greater than interspiracular distance. First dorsal fin greater than second in height. Individual teeth with small lateral cusplets; upper and lower tooth bands roughly equal in width and broadly rounded.
背部有在体盘，腹鳍与尾部上的不规则的网状淡褐色到红褐色的图案,定界线白色或乳白色的椭圆形; 在体盘上的可变大小的肾脏形而圆形斑点 , 与在背鳍与尾鳍鳍上的白色小斑点。 眼大的而且凸出。 圆形的喷水孔有显着升高的边缘与完全的前侧边缘。 眼间距大于呼吸孔间的距离。 在高度方面的第一背鳍大于第二个。 个体牙齿有小的侧面 cusplets; 上、下齿箍概略宽度相等而且宽广地圆的。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00470 - 0.02937), b=2.88 (2.66 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Assuming fecundity<100).
Fishing Vulnerability (Ref.
