خارهاي باله پشتي (کل) : 1; خارهاي باله مخرجي: 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).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00303 - 0.02871), b=3.05 (2.80 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.3 se; based on size and trophs of closest relatives
جهندگی (Ref. 120179):  متوسط, كمينه زمان لازم براي دو برابر شدن جمعيت 4/1 – 4/4 سال (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
