Morphology | Morphometrics
soft rays: 6. Lateral line ossicles 66-70; pectoral spine with serrations on the anterior (27-29) and posterior (6-15) edges. Can be differentiated from Sisor chennuah and Sisor torosus in having a more slender body (body depth at anus 5-5.4% vs. 5.6-7.8) and from Sisor rheophilus in possessing a smaller eye (9.4-12.2% HL vs. 13.2-16.3) and a shorter snout (53.9-55.7% HL vs. 56.2-60.3) (Ref. 55921).
Inhabits streams with sandy bottom and strong currents (Ref. 1479).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00252 - 0.01200), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (45 of 100) .
