Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 1; Afterflossenstacheln 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles, but bordered by a narrow, black, hardly visible, basal membrane; outer mandibular barbels with numerous, rather long, simple and thin ramifications; branches of inner mandibular barbels shorter, subdivided and partly tuberculate; mandibular teeth rather short, numbering 37-47; denticulations of pectoral-fin spines weaker on outer than on inner margins; dorsal-fin spine smooth anteriorly and weakly denticulate posteriorly; humeral process blunt, at most about twice as long as deep, its upper margin more or less convex; adipose fin rather poorly developed and distinctly separated from rayed dorsal fin; body covered with irregular, more or less coalesced spots (Ref. 57223).
Coloration: rather dark, lighter ventrally; body entirely covered with brownish spots and marblings against a lighter background; spots on ventral body regions also large, but lighter; all fins marked with spots aligned in transverse series; adipose fin of the same colour as rest of body; top of head also spotted (Ref. 57223).
Maximum TL was recorded at 14.8 cm (Ref. 57223). Oviparous (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00427 - 0.01860), b=2.94 (2.76 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
