簡短描述
型態特徵 | 形態測量圖
Easily distinguished from H. nemurus by the shape and coloration of the caudal, adipose, dorsal and anal fins, the shape of the snout, occipital process and body. Has broad and conspicuous black margin all around the caudal fin (versus the fin has at most a dark narrow posterior margin), the fin is more deeply notched, the two lobes are very long and narrow, the lower lobe is about 3.5-4.0 times longer than the median rays (versus the lobes are broader and shorter, the lower one being about 2.0-2.5 times longer than the median rays), and the upper lobe regularly tapers (versus the upper lobe is somewhat rounded posteriorly, with the upper simple principal rays produced into a filament). The adipose fin is shorter, its base is included about 1.5-2.0 times into the distance between the posterior extremity of the dorsal base and the adipose origin (versus about 1.0-1.5 times in H. nemurus). Dorsal fin has a more slender appearance; membranes between the rays are narrower so that the fin has a more triangular appearance. The last branched ray is about 2-3 times in the length of the first branched rays (versus about 1.5-2.0 times) and the dorsal spine is about 2.5 times in the predorsal length (versus about 3 times) and about equal to distance between head and dorsal base (versus shorter). The anal fin is triangular (versus rounded); the snout is more protruding and most of the tooth band on the upper jaw is exposed (versus only part of it is exposed in H. nemurus); the occipital process is either visible or at least can be felt through the skin and muscles to the dorsal fin origin. The posterior part is deeply buried in the muscles and cannot be felt); and the female genital papilla is relatively longer (reaching anal origin, versus not reaching) (Ref. 37837).
容易地與尾鰭，脂肪，背鰭與臀鰭，吻部的形狀的形狀與顏色, 後頭骨突起與身體的 H. nemurus 區分了。 有寬而顯著的黑色邊緣在尾鰭 (最多對鰭有一個深色的狹窄後緣) 的周圍四處, 鰭是更多的凹槽深的, 兩者葉是非常長而狹窄又下面的葉大約倍 3.5-4.0 是中央的鰭條 (對葉更寬與更短, 作為大約倍 2.0-2.5 中央的鰭條下面的), 與上葉經常地小臘燭.(在後部地對上葉是略微圓形的, 與上面的單一主要的鰭條伸展到一個絲狀突起) 脂鰭比較短, 它的基底被包括大約 1.5-2.0個次進入那背部基底與脂肪的起源後面的末端之間的距離.(對大約 1.0-1.5個倍 H. nemurus) 背鰭有一個更細長的外表; 在鰭條之間的薄膜比較狹窄，所以鰭有一個更接近三角形的外表。 最後的分枝鰭條是大約 2-3 倍第一個分支條 (對大約 1.5-2.0 倍) 的長度，而且背部棘是大約 2.5 倍前背的長度 (對大約 3 倍) 大約等於頭部與背鰭基底之間的距離.(對比較短的) 臀鰭是三角形的;(對圓形的) 吻部是更多凸出與大部分的齒箍在上頜上被暴露;(對不過它的部份在 H. nemurus 被暴露) 後頭骨的突起或是看得見的或者至少可能是毛氈經過皮膚與背鰭起源的肌肉。 後面的部份是埋藏在深深地之中的肌肉而且不可能是毛氈); 而且母魚生殖乳突是相對較長的 (達到臀鰭起點, 對不達到).(參考文獻 37837)
Appears to be found only in the lower reaches and estuaries of large rivers (Ref. 40801).
