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 unbranched, longer than head, without tubercles and bordered by a narrow, but rather long, basal membrane that extends over half their length; inner mandibular barbels with few, short, sometimes subdivided, ramifications; mandibular teeth moderately developed, numbering 16-27 (27 in the holotype); denticulations of pectoral-fin spines almost as strong on outer as on inner margin; dorsal-fin spine smooth anteriorly, except for some apical denticles; humeral process relatively pointed and granulose, keeled ventrally; adipose fin low, rather short, its length less than 3 times the distance between rayed dorsal- and adipose fin, pointed posteriorly and well separated from rayed dorsal fin; body entirely spotted (Ref. 57223).
Coloration: ground colour rather light with darker marblings on back and sides, less distinct on lower parts of body; all rayed fins covered with non-aligned spots; adipose fin of the same colour as body; in juveniles, spots larger, fewer and less isolated (Ref. 57223).
Maximum TL was recorded at 18.5 cm (Ref. 7362, 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=0.01122 (0.00437 - 0.02882), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.5 ±0.29 se; based on food items.
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).
