Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 5 - 6; Anal soft rays: 8 - 10; Vertebrae: 31 - 32. Distinguished from all its congeners by the following combination of characters: head length 22.0-28.6% SL; depth of caudal peduncle 8.8-10.7% SL; length of anal-fin base 15.2-19.1% SL; eye diameter 12-16% HL; length of nasal barbel 57-92% HL; 3-4 serrae on the posterior edge of the pectoral spine; and caudal fin emarginate (Ref. 30226).

Inhabits large muddy river channels. Not seen in the markets (Ref. 12693).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
