Short description Morphology | Morphometrics

Dorsal soft rays (total): 13; Anal soft rays: 14 - 18; Vertebrae: 36. Devario annnataliae differs from all its congeners in Sri Lanka by the combination of following characters: body depth 24-27 %SL; snout length equal to or greater than eye diameter; color pattern consisting of 5 or 6 irregular, dark blue vertical bars on anterior half of body; P stripe, originating just anterior to dorsal-fin origin; 16-17 predorsal scales; dorsal fin with 10½ branched rays; anal fin with 11½-14½ branched rays; a minute process on first infraorbital; presence of danionin notch; origin of dorsal fin to hypural distance, when carried forward, falling well short of posterior border of eye; pectoral fin, when adpressed, just reaching origin of pelvic fin (Ref. 118056).

Inhabits torrents close to the foot of Brahmana Ella waterfall (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) .
