Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal soft rays: 10 - 13; Vertebrae: 50 - 51. Can be differentiated from its congeners by the unique combination of the following characters: head extremely depressed and broad; dorsal spine well ossified, long (11.9-14.8% SL), and with 10-12 serrations on the posterior edge; cream-colored coracoidal region; caudal fin dark grey, with cream procurrent and first principal caudal rays; maxillary barbels reaching to middle of dorsal-fin base (143.7-195.4% HL) (Ref. 38441). Smooth flat skull roof; occipital process reaches basal bone of dorsal fin; 10-11 soft pectoral-fin rays; no stripe on body (Ref. 12693). Presence of white markings on pectoral fin and dorsal fin tips, anterior edge of adipose, upper and lower margins of caudal peduncle and caudal, including filaments (Ref. 43281).

Biology     Glossary (e.g. epibenthic)

Lives in large rivers with fast flowing water over muddy substrate (Ref. 56749). Appears to be restricted in the middle reaches of rivers (Ref. 40801). Feeds on insects, prawns and fishes. Sold fresh in the markets (Ref. 33813).

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=0.00457 (0.00198 - 0.01053), b=3.10 (2.89 - 3.31), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.61 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 8,000).
Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100) .
Price category (Ref. 80766):   Unknown.
