Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10 - 11; Vertebrae: 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).

Biology     Glossary (e.g. epibenthic)

Occurs in rapid water habitats (Ref. 1440).

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=0.00933 (0.00305 - 0.02858), b=3.01 (2.76 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
