Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 4 - 6; Dorsal soft rays (total): 53 - 55; Anal spines: 3; Anal soft rays: 47 - 51; Vertebrae: 73 - 76. Belongs to the Macrognathus aculeatus species group but can be distinguished from all other Asian mastacembelids by having only 4-6 spines on dorsal fin (vs. 11-40). Differs further from all members of the Macrognathus aculeatus species group by having only 6-8 rostral tooth plates (vs. 9 in Macrognathus meklongensis to 55 in Macrognathus tapirus) and the details of color pattern (Ref. 83418).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00138 - 0.00633), b=2.94 (2.76 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.2 ±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).
