Morphology | Morphometrics
soft rays: 46 - 50. Barbels short. Head spatulate in dorsal outline; snout rectangular and lower jaw extending beyond upper. Gill arches extended anteriorly. Suprabranchial organ well developed. Pectoral spine serrated on base of outer side. Openings of secondary sensory canals display a regular geometric pattern.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00337 - 0.01633), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 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.).
Vulnerability (Ref. 59153
): Moderate vulnerability (38 of 100) .
