简单描述
型态特徵 | 形态测量图
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).
容易地与尾鳍，脂肪，背鳍与臀鳍，吻部的形状的形状与颜色, 后头骨突起与身体的 H. nemurus 区分了。 有宽而显着的黑色边缘在尾鳍 (最多对鳍有一个深色的狭窄后缘) 的周围四处, 鳍是更多的凹槽深的, 两者叶是非常长而狭窄又下面的叶大约倍 3.5-4.0 是中央的鳍条 (对叶更宽与更短, 作为大约倍 2.0-2.5 中央的鳍条下面的), 与上叶经常地小腊烛.(在后部地对上叶是略微圆形的, 与上面的单一主要的鳍条伸展到一个丝状突起) 脂鳍比较短, 它的基底被包括大约 1.5-2.0个次进入那背部基底与脂肪的起源后面的末端之间的距离.(对大约 1.0-1.5个倍 H. nemurus) 背鳍有一个更细长的外表; 在鳍条之间的薄膜比较狭窄，所以鳍有一个更接近三角形的外表。 最后的分枝鳍条是大约 2-3 倍第一个分支条 (对大约 1.5-2.0 倍) 的长度，而且背部棘是大约 2.5 倍前背的长度 (对大约 3 倍) 大约等于头部与背鳍基底之间的距离.(对比较短的) 臀鳍是三角形的;(对圆形的) 吻部是更多凸出与大部分的齿箍在上颌上被暴露;(对不过它的部份在 H. nemurus 被暴露) 后头骨的突起或是看得见的或者至少可能是毛毡经过皮肤与背鳍起源的肌肉。 后面的部份是埋藏在深深地之中的肌肉而且不可能是毛毡); 而且母鱼生殖乳突是相对较长的 (达到臀鳍起点, 对不达到).(参考文献 37837)
Appears to be found only in the lower reaches and estuaries of large rivers (Ref. 40801).
似乎发现只在大河的下面范围与河口中.(参考文献 40801)
