簡短描述 檢索表 | 型態特徵 | 形態測量圖

背的軟條 (總數) : 6 - 7; 臀鰭軟條: 4; 脊椎骨: 18 - 20. No tubercles in skin covering eyeballs and on ventral surface of disk except a few near bases of pelvic fins. Interorbital and mouth both exceptionally narrow. Conspicuous chalk-white oval marking on midline of lower jaw. Teeth present on palatines and vomer. Cephalic lateral-line counts: subopercular usually 6; preopercular 2. Tail lateral-line counts 9-13. Paired fins slender, moderately strong with fin membranes transparent. Tips of pectoral rays fleshy. No tubercles on fins (Ref. 35447, 40826).
沒有小瘤在皮膚覆蓋的眼球而且在體盤腹面上除一些腹鰭基底附近。 眼間骨與嘴兩者都格外狹窄。 在下頜的中線上的顯著的白堊色的橢圓形斑紋。 齒位於顎骨與犛骨之上。 頭部的側線計算: 子鰓蓋通常 6; 前鰓蓋骨 2. 尾部側線計算 9-13 。 偶鰭細長的, 強度中等的有鰭薄膜透明。 胸鰭頂端鰭條肉質的。 沒有在鰭上的小瘤.(參考文獻 35447,40826)

Estimates based on models

Preferred temperature (Ref. 123201): 3.7 - 6.8, mean 5.2 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.00925 - 0.05675), b=2.94 (2.72 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.3   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  中等的, 族群倍增時間最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
