Short description Morphology | Morphometrics

This species is distinguished by the following set of characters: 2-3 pale stripes on body, of which 2 extend onto head, a pair of dermal fold fringing base of dendritic organ; nasal and maxillary barbels reach well beyond posterior border of orbit; origin of dorsal procurrent caudal-fin posterior to vertical thorough middle base of pelvic fins, and slightly anterior to vertical through origin of anal fin; 21-26 (usually 23-25) gill rakers; 142-174 (usually 146-174) total rays in confluent median fins; 48-52 (usually 49-51) vertebrae excluding anterior complex vertebra (Ref. 75200).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00197 - 0.01058), b=3.07 (2.86 - 3.28), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (24 of 100) .
