Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 60-80; Anal soft rays : 56 - 63; Vertebrae : 58 - 61. Characterized by its lateral line which appears as a thick white band; barbels extremely short. Head long, broad and flattened. Frontal fontanelle long and extremely narrow. Occipital fontanelle rather small. The `dermosphenotic' and supraorbital bones are separated. Tooth plate extremely broad. Pectoral spine straight and robust. Suprabranchial organ well developed but not completely filling the chamber.

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274 ); Occurs in well-vegetated sluggish river channels and floodplain lagoons. Breeds during the summer rainy season (Ref. 7248 ). Eats invertebrates and, when older, other fishes (Ref. 7248 , 78218 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00794 (0.00432 - 0.01461), b=2.98 (2.83 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.5   ±0.6 se; based on diet studies. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (40 of 100). Price category (Ref. 80766 ):   Unknown .
