简单描述 检索表 | 型态特徵 | 形态测量图

背的软条 (总数) : 10 - 11; 脊椎骨: 31 - 32. Lips with transverse plicae; snout pointed and very prominent, with a fleshy upwards turned small transverse appendix; eyes very small in superolateral (almost dorsolateral) position; sometimes a darkish spot is found on the squamous caudal fin. Can be distinguished from L. sorex but for the snout length, eye diameter and postocular length (Ref. 12456).
嘴唇有横跨的皱摺; 吻尖与非常突出的, 具有一个肉质的以上转了小的横跨附录; 眼非常小的在侧面上方的 (几乎背外侧) 位置中; 有时一个微暗的斑点被发现于鳞状的尾鳍。 能被与 L. sorex 区分但是对于吻部长度，眼直径与眶后的长度.(参考文献 12456)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
