Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines : 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; snout over 50% of head length and over 80% of head width; post-ocular length less than 30% of head length; maxillary barbels slightly shorter than head, bearing externally some short and simple ramifications and a broad basal membrane; outer and inner mandibular barbels with numerous tuberculate ramifications; mandibular teeth long, numbering 6-9 (8 in the lectotype); pectoral-fin spines weakly denticulate on inner margin and very slightly crenulated externally; dorsal-fin spine smooth anteriorly and prolonged into a filament; humeral process deep, blunt, granulose and not keeled ventrally; adipose fin long, low and rather close to rayed dorsal fin (Ref. 57223 ). Coloration: general appearance rather dark, with ventral areas lighter; outer margins of caudal-fin lobes black-edged (Ref. 57223 ).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  2.9   ±0.3 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 to moderate vulnerability (29 of 100) . Price category (Ref. 80766 ):   Unknown .
