简单描述 检索表 | 型态特徵 | 形态测量图

背棘 (总数) : 0; 背的软条 (总数) : 14 - 17; 臀棘: 0; 臀鳍软条: 28 - 33. SL/BD = 4.4-6.1. Dorsal much smaller than anal inserted almost midway from origin of anal (Dorsal-Anal fin base ratio 0.32-0.46). Pectorals at most as long as head with posterior end not extending beyond origin of pelvic fins. Thin caudal peduncle with height 22.6-31.5 x SL. Color similar to B. brachyistius. Snout projecting and curved downward.(Ref.4967)
SL/BD=4.4-6.1. 背鳍远小于臀鳍从臀鳍起点 (背鳍、臀鳍鳍的基底比 0.32-0.46) 几乎中途插入. 胸鳍最长等于头部有后端不延伸超过腹鳍起点。 细的尾梗有高度 22.6-31.5 x SL。 颜色类似 B. brachyistius 。 吻突出的而且弯曲向下的。(参考文献 4967)

生物学特性     字汇 (例如 epibenthic)

Affinities: related to Brienomyrus brachyistius, distinguished by longer anal fin in Brienomyrus longianalis and by lower peduncle height SL ratio. May be limited to the delta and the lower reaches of rivers (Ref. 3203).

分类相关: 与 壮象鼻鱼[Brienomyrus brachyistius] 有关了, 藉着 长臀壮象鼻鱼[Brienomyrus longianalis] 的更长的臀鳍区别了与藉着梗高度 SL 比下游。 可能仅限于三角州与河的范围下游。 (参考文献 3203)
