Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal soft rays: 68 - 73; Vertebrae: 48 - 50. Distinguished from all congeners in having a unique combination of the following characters: lack of dorsal fin; vomerine in two separate patches; head width 7.9-9.4% SL; 24-28 gill rakers on first gill arch; 9 branchiostegal rays; and more laterally positioned eyes with only ventral half of orbital margin visible when head is viewed from below (interorbital distance 34.2-43.4% HL) (Ref. 55768).

Feeds on invertebrates and small fishes. In the Cambodian Mekong, the fish migrates into the flooded forest during high water periods and returns to the rivers in November where they remain until March (Ref. 55768).

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=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.60 se; based on food items.

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).
