Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 43 - 45. Body rather slender, belly with 24 to 25 + 10 or 11, total 34 to 36 scutes. Eye large, lower jaw projecting. Dorsal fin origin behind midpoint of body; anal fin origin below dorsal fin base. Swim bladder without a posterior tube (or tubes) passing backward into the body muscles. No toothed hypo-maxilla between hind tip of pre-maxilla and blade of maxilla.

Occurs in rivers, reaching at least 650 km up the Irrawaddy, perhaps more. More data needed.

Estimates of some properties 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 (0.00424 - 0.02252), b=3.01 (2.83 - 3.19), based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.5 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100) .

Price category (Ref. 80766): High.
