Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 11; Afterflossenweichstrahlen: 7. Body spindle-shaped and subcylindrical, and head anteriorly compressed. Other diagnostic characters include scaleless abdomen, horizontally placed pectoral and pelvic fins, 35-36 scales along the lateral line series, dark brownish spots in the predorsal region and along the sides of the body, relatively bigger head, deeper body and smaller mouth; hump-like shape in the predorsal region of bigger specimens (Ref. 75068).

Inhabits river with more water current and sandy bottom. Prefers sandy substrate with horizontally placed pectoral fin suited to withstand the water flow (Ref. 75068).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00183 - 0.00952), b=3.16 (2.95 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.2 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
