Short description Morphology | Morphometrics

Maxillary barbels longer than head, bearing externally short and tuberculate ramifications and a broad membrane extending along their basal part; outer mandibular barbels with simple, thick ramifications, branches of inner mandibular barbels tuberculate, sometimes subdivided (Ref. 57223). Mandibular teeth short, numbering 59-66 (Ref. 57223). Pectoral-fin spines very strongly denticulate on inner margin, but nearly smooth on outer margin; dorsal-fin spine denticulate on front margin and prolonged into a filament (Ref. 57223). Humeral process deep, granulose and not keeled ventrally (Ref. 57223). Adipose fin very well developed and contiguous to rayed dorsal fin (Ref. 57223). Colour: General background greyish-brown, colour pattern inverted, the ventral areas being dark (Ref. 57223).

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=0.01380 (0.00618 - 0.03082), b=2.94 (2.76 - 3.12), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.6   ±0.28 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.14).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
