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

Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00371 - 0.02044), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (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.).
Vulnerability (Ref.
59153): Low vulnerability (16 of 100) .
