Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 24 - 26; Rückenflossenweichstrahlen (insgesamt): 89-103; Afterflossenweichstrahlen: 80 - 93; Wirbelzahl: 86 - 90. Diagnosis: head relatively long, 15.7-21.1% SL (mean 18.2%), decreasing with size; origin of first dorsal spine situated before posterior edge of pectoral fin, (-9.5)-(-0.5)% SL [mean (-6.3%)]; body relatively deep, 7.8-9.6% SL (mean 8.7%); distance from tip of snout to last externally visible dorsal spine 49.0-56.2% SL (mean 52.1%), decreasing with size; origin of soft dorsal fin clearly anterior to origin of soft anal fin; lower jaw length 21.3-26.9% HL (mean 23.9%), increasing with size; distance from gill opening to dorsal pectoral fin base relatively short, 4.3-9.6% HL (mean 6.9%); 23+1 to 25+1 (median 25+1) dorsal spines (Ref. 81678).
Occurs in slow streams with a sandy bottom (Ref. 6060). Maximum reported total length 252 mm (Ref. 81678).

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=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.6 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 (19 of 100).
