Short description Morphology | Morphometrics

Dorsal soft rays (total): 12-15; Anal soft rays: 15 - 18; Vertebrae: 35 - 36. Devario udenii differs from all its congeners by the combination of following characters: body depth 26-36 %SL; snout length less than eye diameter; color pattern comprising of 5-6 dark, irregular, broad, vertical bars anterior to level of dorsal-fin origin; 14-17 predorsal scales; dorsal fin with 9½-12½ branched rays and anal fin with 12½-15½ branched rays; presence of danionin notch; dorsal fin origin to hypural distance, when carried forward, reaching middle of eye; pectoral fin, when adpressed, reaching origin of pelvic fin; and P-1 stripe subequal in width to P stripe (Ref. 118056).

Biology     Glossary (e.g. epibenthic)

Inhabits fast-flowing water within moderately shaded areas (Ref. 118056).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00418 - 0.02283), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
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) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
