Short description Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 10; Anal soft rays: 7. Distinguished from Erromyzon compactus by having fewer bars on flank (12 vs. 16-18), a more compact body with pectoral fin extending further backward (3/4 of distance to pelvic-fin origin, vs. 1/2) and pelvic fin reaching anus (vs. not), caudal peduncle as deep as long (vs. depth 1.1-1.3 times in length), a shorter snout (69 % HL, vs. 77-86) and smaller eye (45% HL, vs. 54-56). Possesses numerous tubercles on snout, cheek and opercles, which are missing in E. sinensis, but their development might depend on season and sexual maturity (Ref. 54043).
Collected during rainy season from swift flowing, turbid water over large boulders (Ref. 54043).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00268 - 0.01421), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
