簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 9; 臀鰭軟條: 10 - 11. Head smooth above (Ref. 2988). Maxillary barbel reaching middle of adipose fin in the young and the end of the rayed dorsal in the adult; nasal barbel reaching anterior border of eye (Ref. 52301, Ref. 2988). External mandibular barbels reaching the branchial fissure; occipital processus reaching the interneural bone (Ref. 52301). Longest dorsal fin ray a little longer than head; distance between adipose and dorsal fin equals base of the latter; adipose fin twice as long as the distance between dorsal and adipose fin (Ref. 2988). Caudal fin forked, upper lobe slightly the longer (Ref. 52301, Ref. 2988). Pectoral spine very strong, prominent and strongly serrated (Ref. 36900) on inner side (Ref. 2988). Pelvic fins under last dorsal fin ray (Ref. 52301, Ref. 2988).
Coloration: reddish brown above, yellowish white beneath and the caudal fin dotted with black (Ref. 36900, Ref. 2988).
頭部平滑的上方.(參考文獻 2988) 上頜骨觸鬚在成魚中達到幼魚與有鰭條的背鰭的末端的脂鰭的中央; 鼻骨觸鬚達到眼的前緣。 (參考文獻 52301, 參考文獻 2988) 外部的顎觸鬚達到鰓的裂縫; 後頭骨活動達到背側間的硬骨。 (參考文獻 52301) 長的背鰭鰭條稍微長度超過頭部; 脂鰭與背鰭等於後者的基底之間的距離; 脂鰭兩倍長於那背鰭與脂鰭鰭之間的距離.(參考文獻 2988) 尾鰭分岔, 上葉些微地比較長.(參考文獻 52301, 參考文獻 2988) 胸棘非常強的, 突出的而且在內部的側邊上深鋸齒狀的 (參考文獻 36900).(參考文獻 2988) 在最後的背鰭鰭條下面的腹鰭.(參考文獻 52301, 參考文獻 2988)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00402 - 0.02604), b=2.95 (2.72 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.9 ±0.9 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Assuming Fec>10,000).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
