Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 36.0 cm TL male/unsexed; (Ref. 9271); common length : 20.0 cm TL male/unsexed; (Ref. 55763)
Body somewhat elongate; mouth sub-terminal; cephalic plate prominent, granulated, and rough; pre-dorsal plate narrow; pre-maxillary teeth villiform; vomerine teeth lacking; palate with molariform teeth set in two separate sub-oval plates; inner edge of pectoral spine coarsely notched; caudal fin lobes long, thin, and pointed, about the same length as the head; body dark brown; belly white; flanks silvery blue (iridescent); fins dark or black; barbels dark brown (Ref. 55763).
Found in marine, brackish and fresh waters (Ref. 9271). Rarely consumed due to its small size (Ref. 9271).

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=0.00759 (0.00347 - 0.01656), b=3.07 (2.90 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.4 ±0.8 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (26 of 100).
